Hello to all the lovely Tom Scott newsletter readers joining us here this week. 👋😊👍 I bet you'll find the comments beneath my videos to be a far nicer place than many other TH-cam comment sections. 😁💚
I've loved your work for quite a long time. It's a very delicate act, threading the needle between education and entertainment... And you folk have been doing it consistently, year after year. It takes a ton of work, much of it hidden labor, but those of us who know... we know. Thanks for doing what you do and being who you are. 💚
Can't believe I interrupted watching a 4 hour video about a Star Wars hotel to watch a 2 hour video about fire codes. Another awesome presentation, thank you.
and I can't believe that I would know what video you're talking about, except I knew IMMEDIATELY seriously, how much overlap between Dev's audience and Jenny's audience is there?
There was a fire yesterday 6/6/2024 at the Hyatt Place in downtown Knoxville. It originated in a 7th floor elevator maintenance room. It is amazing that because of everything you talk about there were not any injuries. The fire was contained to just that room. 50 years ago, that could have been a devastating fire, now it barely made the local news. The hotel has some smoke damage from where firefighters had to open doors but the multiple systems worked perfectly to allow everyone to get out. You didn't talk about elevators here but that system kicked in and platformed themselves at the lobby with doors open; even with the controls possibly being on fire.
I love the mundanity of success when it comes to safety. Every rollover someone walks away from, every fire that snuffs out with no lives lost, every ship where the watertight doors make it mere annoyance, every flight where the door blows out and no person does (okay, that one was more luck than not) is a tribute to the will to make things better, sadly, it's usually predicated on the passion of those who have lost loved ones from prior incidents. But those successes are proof that where there is the will, the law mandating it and enforcement, we can save lives.
@@x--.The mundanity brings its own form of risk. After all, there is no greater proof that no good deed goes unpunished than the fact that the poor assholes who busted their butts preventing Y2K have been mercilessly mocked about it being “fake” for 24 years.
Great fun talk. 😀 Just one accessory if you're carrying a hard hat, wear steel toed boots. There is no place that requires a hard hat that doesn't require steel toed boots.
@@phillyphakename1255 You'll need to sew on the green triangle (or whatever your jurisdiction uses) to identify them as compliant boots. Any place that requires safety footwear is trained to look for the compliance indicators. In the US and Canada that's a green leather triangle.
I've worked as a security officer in a large hospital and I'm currently a firefighter Its worth noting that NFPA is not a regulatory body. They do not do enforcement and they do not do fines or criminal charges. The NFPA standards are best practices but are THE standard. Most of the standards are obviously codified into law by the local jurisdiction On the outside of any commercial structure will have an FDC. Fire Department Connection. It allows a fire engine to connect and pump the fire suppression system. The in building system has pumps and water but not the flow that a fire truck can provide direct from a hydrant and pumps etc. can fail but generally the piping will be intact. Its worth noting that fire hydrants are rated by their flow and are color coded. The colors oddly match the order of the sprinkler bulbs. The color of the caps on a fire hydrant let the engineer running the fire truck know what kind of flow they can expect at just a quick glance. Blue is the best. Followed by the traffic light order. Green, then yellow, then Red. A low flow hydrant would require a second engine to connect to a second hydrant and relay pump to the initial engine. A more contemporary fire that resulted in fire code changes would be the the Cocoanut Grove Nightclub fire took place in Boston, Massachusetts, in 1942 en.wikipedia.org/wiki/Cocoanut_Grove_fire Hospitals are designed around fire spread. Carpet, wall coverings, garbage cans. Everything is chosen around fire spread. An elderly person is a walker should be ale to outpace a fire in a hospital. Its part of what allows locked egress doors etc. A fire on one wing would not necessarily unlock doors off the unit itself.
After 25 years as a service engineer I throughly appreciate the power of a polo shirt with a logo, being acompanied can be annoying but if you are really friendly and explain in great depth how a machine works they generally go away in under 5 minutes.
I know you don't need praise but I want to say it anyway: the way you handle questions is admirable. You ensure people don't get missed, try to do it in order where possible, defer to experts in the room, admit you don't know things when you don't. It's all amazing and it's a shame not everyone does it like you.
🥹 thank you so much for seeing what I try to put into the vibe when I have a room like this. I really want everyone to feel seen and involved as much as I can
Funfact about an institutional environment I have worked in - a hospital psych unit. Many times individual rooms (specifically the locked rooms) would have individual water/sprinkler shutoffs for that specific room, because people would try to break the sprinkler heads. If someone did, staff could isolate that specific room from the system and prevent the doors from unlocking. Though an alarm would still sound and security would still have to attend the room.
@@DeviantOllam There was a service closet directly next to each of the secured rooms - staff could shut off water, sprinkler, power, and access a cleanout for the drains so all that work could be done without entering the room. The closet contained manual valves. The staff station also included a water shutoff electronic button, but I dont believe that affected the fire sprinklers, just the washroom. When occupied, the rooms had to be constantly monitored by a staff member who would have a key to open those closets.
Police department cell blocks have a similar issue, as matches and lighters are relatively easy to smuggle in. I have worked with a customer that installs Marioff Hi-Fog systems in institutions like these. Instead of traditional sprinkler heads, they have solenoid-controlled valves that pump out mist that is supposed to both reduce water damage and allow creating buffer zones to trap smoke particulate. I wrote a valve control app that runs on a touchscreen computer in the CCTV control room. When a fire detector is triggered, the traditional backup fire alarm system defers the general alarm for a short time while our software commands valves open in affected zones and lets security guards assess the situation. Valves can be both shut and opened remotely and the pump can be stopped in case the valves are stuck open. The final backup shutoff is the manually operated gate valve in the pump room. So, if you ever get too drunk in $EU_COUNTRY, get thrown in the cell and see a fancy sprinkler system, don't try to trigger it. You'll only end up getting wet.
When will this guy learn that no one cares if the talk is long, or about "boring stuff". Everything he touches and talks about is gold. JUST FREAKING GO!!! Just talk until the sun comes up!
Hi! I'm a former water-based fire suppression system technician. In regards to water companies shutting off the water, *most* places have a domestic service line and a fire service line, both tapped from the under-street water main. If you don't pay your water bill, the domestic service line gets shut off. Your faucets stop working, your showers stop working, but the fire risers remain in service. There's very few instances in which, unless the huge city main is disrupted, a fire riser will lose water. Even abandoned buildings with sprinklers will have water service to the riser(s) in most cases unless, say, the system is activated by vandals or scrappers and the fire department cuts off the service at the main riser gate (OS&Y) valve. There's of course exceptions to this in rural areas where water isn't provided by a waterworks, or cities and such where age is a consideration, but even in hundred year old buildings on the Hudson, *most* buildings with sprinklers have a water line for people and a water line for fire protection piped separately off the water main or tapped *before* the domestic service meters and shutoff. I don't know anything about the law when it comes to payments or domestic water service and I imagine it varies *wildly* from jurisdiction to jurisdiction, but there's a prevailing wind of "I don't care how much they owe you, unless it's impacting the health or ability of others to have safe drinking water, if the building's occupied, you give them water. Sue them if you want the money" and I think that's a good thing. Feel free to ask me anything about sprinkler systems, and if I know the answer I'll be happy to help!
it happened at the building i work at. The pressure in the water main was cut by the city. The city turned the water back on during a saturday afternoon and SURPIRSE! Sprinklers went off in the boiler room, elevators flooded.... A year later there is a company in the building now going through every floor testing pressure.
1:02:12 I’ve got a funny anectdote for this, I was working in the back room at a Lowe’s when my manager came over with a forklift and one of the new employees. The employee said “I wasn’t aware that was an emergency exit” and the manager replied “Do you think something like painting a yellow box on the ground would help identify it as such?”. The new guy said yes at which point the manager used the forklift to shift a pallet out from in front of the emergency exit revealing the bright yellow painted box on the ground.
i can't wait to hear what they reply. they'll catch some of my small errors! (like delayed egress... i said 30 seconds or 60 seconds, that's incorrect... 30 is the maximum allowable. 15 seconds is much more common)
@@DeviantOllam I play DND with a former NFPA guy, so I'll see him this Friday. Codes dense and has changed a bunch over the years. It's one of those ones where if you're just reading the updates like patch notes, it's not too bad but getting into it is rough.
I have an amber light that I got off a truck at a salvage yard. Don't need the cord, just chopped it off and can magnet it to the truck whenever I need to park somewhere unauthorized froa few minutes. Kick on the hazard flashers and go about my business. I already drive a white pickup, and a few magnetic " This vehicle makes frequent stops" or Speed monitored by GPS, a yellow vest on the passenger seat, hardhat and a lunch bag...no one will bother you. The magnetic door signs are good...but if you want to go all out, buy a used Cricut vinyl cutter and make yourself some FakeCo. door decals. They look authentic and remove easy enough if you don't leave them on too long. You can even pre-make them and put them on a rental if needed.
When you hit your big box craft store, looks for PSV ( pressure sensitive vinyl). You don’t have to buy Cricut brand and usually something is on sale. Also, they have 2 varieties usually. One is “Permanent” for vehicles, water bottles, that stuff. The Semi-Permanent is usually for wall decals and things you really need to be able to peel off. This will safe uncomfortable explanations to a rental place later. Tip: also buy the clear transfer vinyl. It’ll save so much time trying to line up the pieces later so long as it lined up in the software. 🙃
@@coffeegonewrong you can also weaken the adhesive using talcum powder. Also, what if you Turtle Wax the truck first? If the decal is not actually stuck to the clearcoat but has a sacrificial layer in between, you should always be able to remove cleanly without harsh solvents.
What kind of trouble can a building owner get into for violating fire code? Well quite a lot over here in NL. I used to rent an apartment from one of the largest estate companies in the country. One day I couldn't exit through the fire exit like I normally did, so I had to walk the 100+ metres to the central hall in order to get out of the building. So I checked the outside, as it turned out the outside of the fire exit has a key hole that my key would open. However it was only half a cylinder in the lock and the inside was just a blind, no way to unlock the door. Turns out residents of the building, including those on the ground floor, could lock the door from the outside with their key and then it couldn't be unlocked from the inside. I called my boss to tell him I'd be a little bit late that day and proceeded to call the fire department. They sent an inspector out to me, we walked the building and it turned out that each of the 14 fire exit doors had this issue and 4 or 5 of them were at that time locked from the outside. Suffice to say the inspector was not impressed. So he did the sensible thing, called some of his colleagues in other municipalities. They discovered that this method of saving a few euros on half of a lock cylinder was pretty much in every building that estate company owned. So the inspector called up the estate company, had them send "someone in charge" over to my building and told them in no uncertain terms that they had 48 hours starting the following morning at 6am to get ALL of those doors sorted and up to code. Failure to do so would be met with a 1500 euro fine per door per day that it wasn't in compliance. It took the estate company close to a month to fix thousands of doors, it cost them close to a million euro in fines. They never replaced the half-cylinder locks, as that'd be too expensive. They just send maintenance crews with axle grinders to cut the deadbolts off. Making the doors self closing, self latching, but no longer lockable.
That's honestly really disheartening to hear. The fact that nothing really got fixed makes the fine seem so pointless. Just the cost of doing business.
@@thewhitefalcon8539 And where is the documentation stating that it has been tested in the new configuration and will open under conditions found in an emergency? Testing and certification by organizations such as U.L. and TÜV are required for a reason.
I watched the whole thing in one go. I wish i had been at that conference. The amazing thing about this is absolutely no ad breaks. I have seen other things like this where they had an unskippablr ad every five minutes. Thank you for valuing my time.
I will absolutely never use this information professionally, but it will forever sit in the back of my head from now on as I inspect every door and all fire hardware I see to someday find one egregious enough to contact the AHJ
Diesel engine pumps are connected to an external water source (large tank) designed to run until total destruction if need be. It’s also double redundant (2 starters and 2 battery sources). I used to work on them and they’re badass. Also usually the company that services the generator (Cat Cummins etc) services the fire pump.
Canadian Generator mechanic here: That's called Chicago Protocol up here and some places do use it. Unfortunately a lot of places here still have engine protection shutdowns because they're allowed to... Absolutely stupid to me. If that pump is running it's because it HAS to, and in my opinion they should run until they melt or seize if necessary. We have some big holes in life safety legislation up here.
Oh hell yeah, two straight hours of conversational style infodump on safety codes. I love how fluid and engaged this whole talk is 😁 Thanks again for making sure it was recorded to be posted online Deviant
Great talk! I used to be front of house manager in a large museum with a conference centre attached, so I've seen just about every possible way of defeating fire safety provisions anyone has ever come up with. Events staff using a fire exit corridor as a storage closet was a classic, personal favourite was probably when I saw a fire extinguisher missing from its hook, went to look for it and found it propping open a fire door. But the most shocking example was when the museum converted a basement into a brand new flagship gallery (cost in the milliions, fancy architects, etc) and then decided it needed a new gift shop kiosk just outside the gallery entrance. Fine, but then someone (not the architects clearly) OK'd converting the bottom of the stairwell into a stockroom. Apparently nobody realised this was a no-no and I was the first one to express any sort of concern! In the end the "fix" was to designate that stairwell as "not a fire exit" which meant we had to reassess all the building capacity numbers and redo tons of signage, rework our evacuation sweep routes, and on busy days, monitor the visitor numbers in one half of the building to ensure we didn't go over capacity. Absolute nightmare for such a stupid reason. And not even worth it since they ended up closing the gift shop kiosk after the first exhibition because it didn't even take enough money to pay for the retail assistant staffing it.
Lol, in the spring, I saw some things that seemed off to me at my university. So I read the NFPA 101 and IFC fire codes and sure enough they were violations. Reported it to our fire and life safety department, fixed same day. I might also be a bit autistic 😅
Def up there. I love the elevator talk too. Between the elevator and now this, I'll likely re watch many many times. I love going to conferences where the speaker is engaging and draws in the audience. When it's just a dry reading slides one by one, word for word, I just want to fall asleep. Lol
This might just replace your adult industry talk as my favorite Dev' talk. Adult industry was so great because it was clearly designed for a specific audience. Those were always my favorite essays to write in school, thinking about what to include for the target audience, what wording to use, etc. That talk was a masterclass of the genre. Turns out with this speech that you also have a target audience: nerds. We all get super excited about connecting dots between disparate fields, like security and safety. You rocked the room.
@@ZMacGregor yes. it was a talk about physical and digital safety at a PH run conference. The overlap between people providing film services and people providing in person services is narrowing, you might follow someone on OF then meet with them IRL, maybe at a hotel, maybe at a personal residence. What's the security like? Hey, just so you know, under door tools exist! EXIF data exists on photos, too, so be careful with what data you are leaking for creepers to find you. Dev is all about threat modeling. Adult industry people have threats, and that talk walked through how to think about and respond to them, and he did it in a very empathetic and competent way.
@@ZMacGregorAdult film stars are much more likely than the average person to have some creepy stalker try to break into their house or place of work, and the sets they work at probably aren't that well secured. IIRC Dev's talk focused on ways to prevent creeps from getting places you don't want them.
I was walking through an art museum in St Petersburg, prior to the Russian invasion of Ukraine. There was a bunch of people crowded around a Leonardo da Vinci. I glance over, and there on the wall is the Shits On Fire Yo painting, being completely ignored. It was the highlight of my trip.
The thing about murals, it's semi common in some institutional environments (think dementia wards) get exemptions to disquse the doors to prevent residents getting fixated on the exits. They get exemptions based on having procedures to assit and flashing lights on the exits.
@1:00:40 this reminds me of the Shmoocon 2019 party where the fire alarm went off and hotel security (Hilton, again, heh) wouldn't let people take their drinks outside, which caused back-pressure on people trying to evacuate, leading to a *very* slow evacuation... Something like >10 minutes to get everyone out, while it only took 90 seconds for everyone to get back in once the all-clear was given
i remember that. i definitely took my drinks outside, stiff-arming hotel staff in the process. they have absolutely no authority to prevent free movement of people during an emergency situation.
5-over-1's are actually specifically a weird edge case in the fire code - the ground floor is ordinary or noncombustible, and then the upper 5 stories are a combination of engineered wood beam (similar fire performance to timber framed) and normal wood stick construction. Essentially a 5-story apartment building made out of wood, sitting on the roof of a strip mall. They're basically firetraps compared to what you'd expect a 6 floor mixed-use building to be, and exploit the edge cases in the fire and building codes to enable cheaper construction. And they look pretty dang fireproof at ground level.
For anyone who hasn't seen it, it's worth looking up those photos of a room burned to an absolute crisp, and everything outside of the door is fine. We think a door, especially a wooden one, isn't going to do much against a fire. Makes it a bit hard to internalize all the advice about checking for smoke under the door, or not opening the door if the handle is hot. But wooden fire doors are no joke. Doors will save your life. The talk was great fun! But also, it's cool how we're all going to be paying a lot more attention to doors as a fire safety device.
Please please please tell that to the fine folk on the second floor of the apartment building I used to live in. They always jammmed the door labelled "FIRE DOOR; KEEP CLOSED" open.
Right. When people tell me my battery box has to be metal, I just point them to the fire rating of oak plywood. (it would take hours for a fire to get through. li-ion battery fires only last minutes. much of what you see in yt videos is the other things it sets of fire... carpet, tires, etc.)
I have an answer to your question about missing bottom rods as a building maintenance technician. They get broken and are too expensive to replace. People running carts into them is most common. Far too many of our doors have received field expedient LBR conversions, with varying degrees of success.
Hey Deviant, I've worked at a place that had a sauna. The sauna had an entry area outside of it with a door to close it off from the rest of the hallways, and the engineers didn't do preparation for the heat in that area. The 155 f burst soon after the place was up and running. The building had that sprinkler trigger, and had to replace it with a green one. Thought you might get a kick out of this!
I swear this dude works a crowd so well! I've watched so many of Deev's presentations on "dry" topics and it never feels slow or uninteresting. I can imagine these conversation skills could only help when doing pentesting :)
HVAC tech here. In our hall way shelves are several aerosol cans of CO provided by (I think) it was April Aire for the purpose of testing their CO detectors. They have been there for years unused but I know they exist. I just checked and they are available at Home Depot too.
I'm glad I got to see this in person, and at my first con. This is my favorite talk of Deviant's (your's?) so far, up there with and above the elevator talk and Through the Eyes of a Thief. Like many people, the door inspection was easily my favorite part and was a great way to engage us (the audience). The badges afterwards were also great fun, so thanks for doing to work to set that up (and not getting brought down by the curse of live demos). TL:DR; Really awesome talk, and it definitely contributed to making my first con an awesome one. Thank you.
Absolutely ELECTRIC crowd for such a dry talk. Only Deev is capable of such things. Genuinely excited for the paint drying (and whisky tasting) seminar. With a bonus story about how deev broke into a building by pretending to test for proper latex content in wall paint ((Non occupancy spaces may be litigated differently)ask your AHJ) "Mister security guard, I would love to leave like you want me to, but these walls FAR exceed the max permissible DEEViation for latex content!" (Edit: misspelled "me")
My old condo building learned about triggering an alarm by opening a sprinkler the fun way. One of our neighbors had an upstairs neighbor playing loud EDM into the small hours of the morning. He started pounding on his ceiling with a broomstick, and hit the sprinkler head. Those evacuation alarms are VERY loud.
You also can bore people to death with your copy of NFPA 70 (edit: I appended sn E in error, it's just 70) the National Electric Code. I'm an electrician and physical plant mechanic. I work in access controlled facilities. Some are tied to fire suppression, some are not. I also have fail-secure doors that won't open from the outside even in a fire. So, in less modern structures where the old code is grandfathered in, don't assume anything. I work in facilities from the 19th century to today.
Sorry to be pedantic but NFPA 70 is the National Electric Code, NFPA 70E is the "Standard for Electrical Safety in the Workplace". 70 is the code your electrical installation must conform to, while 70E is about safe work practices for keeping electricians safe on the job.
@@HOLOGRAPHICpizza My bad. I have been doing continuing ed on arc flash prevention, risk assessment, LOTO, and PPE. I have 70E on the brain. Also haven't been sleeping great and some of my gaffes are the product of insomnia. You are correct.
Also @deviant, in my experience if you experience a water loss on a charged wet pipe system IT WILL trigger a "Low-pressure" alarm on the newer systems and on older systems it generally does trigger a full alarm activation. Thanks
@@DeviantOllam It can if it's a deluge type. (personally never seen such) I've seen just such an activation due to an ice storm power outage. It was overflowing the stand pipe turning the parking lot into a skating rink. While I was in the building (telco), I didn't have access to dismiss the alarm. (facilities moron has to get there to do that.) I did climb the 9 flights of stairs to confirm there was no fire on the 9th floor. (there were no secondary alarms, so relatively safe to venture up there.)
The podcast "Make No Law" (Can't recommend enough, only a few episodes, does great storytelling around major 1A law cases) has an episode talking about the trope of "Fire in a crowded theater". As a lead in to your Theater Fire segment it would be cool to see a slide talking about the trope before going in to how horrifyingly real theater fires were in the early 1900s. In the discussion on fire sprinklers your slide showed varying size gas bubbles in the liquid. "Ordinary Structures" had the smallest. It would be interesting to see how big of a gas pocket higher temp bulbs have! Also, definitely don't hang clothes in them. My brother-in-law did that flooded his second storey apt's bathroom pretty badly. I'm disappointed Group H wasn't "Hotels, Motels, Holiday Inns" huge missed opportunity. Holy shit I miss Mitch. I drank more as the talk went on (definitely not noticeable in critique length). I loved it. Thanks for continuing to share your knowledge and expertise freely Deviant. You rock.
Quite the most outstanding comment of this length that I've read in a while! Have an internet award! 🏆 For real, though, you really were hanging on to every detail and that's really cool! I've never seen the ultra high sprinkler bulbs, myself... Sure would like to! (Also, your Rapper's Delight reference there gave me a huge smile!)
Remember folks, it's only illegal to yell "fire" in a crowded theater if there IS NO FIRE. If there actually IS a fire in a crowded theater, it may be considered the appropriate course of action depending on the situation!
I can say from experience, loss of water pressure/supply due to shutoff in response to a main break can/will set off the alarms on the standpipe. A small business I used to work for had exactly this happen. The owner who lived down the street got a call around 4/5am from the fire alarm company letting him know that either the water was disconnected or the sprinklers were going off. This resulted in a 50-something year old man running, in sweatpants and a t-shirt down a Boston street in winter.
don't industrial extinguishers usually have pressurized systems with check valves to prevent backflow? water stagnates in these systems, I wouldn't want any of that feeding back into my drinking water
@@TheAechBombIt might depend on how old the fire suppression system is. Boston has some of the oldest still-in-use buildings in the U.S., so there’s a lot of places where stuff’s been grandfathered in past multiple code changes.
I work for an engineering firm. It is AMAZING what a hardhat and clipboard does to get you access. And some engineering companies are lazy. They put the door power supplies above the lay-in ceiling above the UNSECURE side. Mag locks, cut power. Electric strikes, a quick jumper to the low voltage power supply to open. All you need is a screwdriver, a bit of wire, and something to stand on. And there are a lot of ladders in the typical building.
A common one for telecom and datacenter goes by the trade name SAPPHIRE, it’s meant to be non-conductive and low cleanup. Also supposedly only mildly toxic until heated. When it encounters fire it’s best to clear the area but you can survive accidental discharges. ( this anecdote was from an fire system installer about his own personal experiences)
All the motorsports I'm aware of use AFFF. (non-PFOA/S that shit's been banned for decades.) It's still water based, so not a great idea around powered systems. (eg. data center.)
Commercial aircraft also sometimes will have water fire extinguishers as well as the Halon. If you see a gray fire extinguisher, that's a water based extinguisher.
On the matter of vehicle cleanliness - no matter how dirty we field guys got, we were always expected to keep our work trucks (aka our “rolling billboards”) clean and presentable, especially if they were newer. The public may not see us working, but they sure as hell see the trucks.
Awesome talk as always. A little anecdote in reference to the section around 50 mins with fake service vehicles. I know a guy who got lost and ended up in a "secure" area at Pratt & Whitney, he had a silver Jeep with a Whelen light bar on the roof he used for roadside assistance. He made a wrong turn and security waved him right through a security checkpoint. He was trying to find the way out and started seeing "Restricted Area" signage... He was helping block traffic at a wreck with that same vehicle one time and cops put a guy in his back seat thinking it was a patrol car. He had a net behind the front seats to hang stuff on and they apparently thought it was a cage. Never underestimate what you can get away with when you drive a plain vehicle with emergency lights.
1:39:00 that burning-through door - worth the whole 2 hours just to see that. Imagine being in that room with literal hell trying to get at you. Fire safety training for employees and students should include that clip. They should show it in public schools.
Little-known fact. Per the NEC, you are allowed to wire a fire suppression pump and fire alarm systems directly from the supply side of the electrical system. That means no breaker. Fire pumps still need to have a service disconnect somewhere, but the point is, on fire pump systems if you turn off all the breakers, the pump and alarms may still have power.
Question at 25:00. Dry pipe systems rely on compressed air to hold the water back. if the compressor looses power, the air pressure will eventually decrease in the pipe, allowing the water to overcome it, and flow into the formerly dry pipe. This will trigger a sprinkler flow alarm, but will not cause water to discharge form sprinkler heads.
@@DeviantOllamDry systems typically have a standby compressor to maintain pressure. There is a pressure switch that monitors the system and cycles the compressor when needed.
1. My building is testing fire alarms while your premiere runs, coincidentally. 2. I learned that the countdown sequence you picked wasn't custom-made by the music label I thought made it for their concert premieres 😮
Two things... One, regarding the 5 over 1 thing. You clearly need to be introduced to "Well There's Your Problem", a podcast about engineering disasters. With slides. Two, motion for all future Deviant Ollam talks to be at the end of the conference!
As a fellow neurospicy, that was one of the most interesting talks I've seen in a long time! I'd been interested in this kind of stuff but I realize just how little I know! And it's only making me want to learn more. Stay safe, and carry on!
Same, and not knowing anything going in I keep wondering what is going on with all of the "infiltrate this place and look like you belong" parts of this talk. I'm super entertained but also a little concerned lol
First time I learned about pressure/flow alarms on fire systems was at work, the county water system had a problem resulting in pressure loss and there was some kind of "back-flow" from the fire suppression system setting the alarms off. I'm told back when the building was constructed there were also issues with pressure changes at the top of the hour a huge number meetings ended and most of the toilets were being flushed at the same time caused enough of a pressure change to set the fire alarms off. Apparently they had to put in some kind of additional check valves or pressure tanks to help it absorb sudden changes.
I thoroughly enjoyed your talk. I was a firefighter for 20 years and knew a lot of what you were talking about and you made sprinkler systems fun! I took a college course that made me want to knaw my arm off and beat myself silly for signing up for it. I also got hurt on the job and became disabled so I went back to school to get my degree in Network Security and Social Engineering was one of my all time favorite classes. Thank you for your videos I am already watching another one. Stay Safe!
i absolutely LOVE how eager both you, and the audience are to talk here- the whole talk sofar, like everything ive seen you do has an incredibly wholesome vibe with how happy you've been to engage with the audience
Dev, thank you for that impressive talk - and you know what!? Having your own (original) pages in the video is SOOOOOO good! Even in Europe this is interesting :D
1:00:15 When I was in college, my dorm was set up so that at the bottom of the stairs, your turned left into the lobby and then went out the main doors. To the right of the stairs was a set of fire doors with the typical alarmed push bars. It was astounding how many people would turn left when the fire alarms were going off cause instead of taking the shortest path out.

1:22:00 Pro Tip: All autofocus sucks. If you are in an autonomous filming situation such as this, *always* manually set focus during your setup, and then *turn off* autofocus.
I have a suspicion that the difference between group I and group R for elder care is related to whether it's assisted living, memory care, or independent living. People in an assisted living environment ought to be allowed to get out on their own, but they may not be capable of doing so for medical reasons. Whereas people living in memory care may be capable of leaving but generally wouldn't be allowed egress without staff accompanying them for safety. Then independent living is a lot like a big college dorm for seniors.
Hello to all the lovely Tom Scott newsletter readers joining us here this week. 👋😊👍
I bet you'll find the comments beneath my videos to be a far nicer place than many other TH-cam comment sections. 😁💚
I love when my interests align like this.

Came straight from Technology Connections and enjoyed the entire talk. Awesome!
There was a fire yesterday 6/6/2024 at the Hyatt Place in downtown Knoxville. It originated in a 7th floor elevator maintenance room. It is amazing that because of everything you talk about there were not any injuries. The fire was contained to just that room. 50 years ago, that could have been a devastating fire, now it barely made the local news.
The hotel has some smoke damage from where firefighters had to open doors but the multiple systems worked perfectly to allow everyone to get out. You didn't talk about elevators here but that system kicked in and platformed themselves at the lobby with doors open; even with the controls possibly being on fire.
I love the mundanity of success when it comes to safety. Every rollover someone walks away from, every fire that snuffs out with no lives lost, every ship where the watertight doors make it mere annoyance, every flight where the door blows out and no person does (okay, that one was more luck than not) is a tribute to the will to make things better, sadly, it's usually predicated on the passion of those who have lost loved ones from prior incidents.
But those successes are proof that where there is the will, the law mandating it and enforcement, we can save lives.
@@x--.The mundanity brings its own form of risk. After all, there is no greater proof that no good deed goes unpunished than the fact that the poor assholes who busted their butts preventing Y2K have been mercilessly mocked about it being “fake” for 24 years.
Great fun talk. 😀
Just one accessory if you're carrying a hard hat, wear steel toed boots. There is no place that requires a hard hat that doesn't require steel toed boots.
Non steel toed hiking boots will work in a pinch, but authentic steel toe is better.
@@phillyphakename1255 You'll need to sew on the green triangle (or whatever your jurisdiction uses) to identify them as compliant boots. Any place that requires safety footwear is trained to look for the compliance indicators. In the US and Canada that's a green leather triangle.
My job requires a hard hat and full length boots but not steel toes.
Not true at all.
@@christopherguy1217That green triangle is for the Canadian Safety Administration, and isn’t a requirement in all industrial environments in the US.

Its worth noting that NFPA is not a regulatory body. They do not do enforcement and they do not do fines or criminal charges. The NFPA standards are best practices but are THE standard. Most of the standards are obviously codified into law by the local jurisdiction
On the outside of any commercial structure will have an FDC. Fire Department Connection. It allows a fire engine to connect and pump the fire suppression system. The in building system has pumps and water but not the flow that a fire truck can provide direct from a hydrant and pumps etc. can fail but generally the piping will be intact.
Its worth noting that fire hydrants are rated by their flow and are color coded. The colors oddly match the order of the sprinkler bulbs. The color of the caps on a fire hydrant let the engineer running the fire truck know what kind of flow they can expect at just a quick glance. Blue is the best. Followed by the traffic light order. Green, then yellow, then Red.
A low flow hydrant would require a second engine to connect to a second hydrant and relay pump to the initial engine.
A more contemporary fire that resulted in fire code changes would be the the Cocoanut Grove Nightclub fire took place in Boston, Massachusetts, in 1942
en.wikipedia.org/wiki/Cocoanut_Grove_fire
Hospitals are designed around fire spread. Carpet, wall coverings, garbage cans. Everything is chosen around fire spread. An elderly person is a walker should be ale to outpace a fire in a hospital. Its part of what allows locked egress doors etc. A fire on one wing would not necessarily unlock doors off the unit itself.
After 25 years as a service engineer I throughly appreciate the power of a polo shirt with a logo, being acompanied can be annoying but if you are really friendly and explain in great depth how a machine works they generally go away in under 5 minutes.
Tom Scott brought me here. This lecture shows perfectly that an enthusiastic teacher makes any subject interesting!
I know you don't need praise but I want to say it anyway: the way you handle questions is admirable. You ensure people don't get missed, try to do it in order where possible, defer to experts in the room, admit you don't know things when you don't. It's all amazing and it's a shame not everyone does it like you.
🥹 thank you so much for seeing what I try to put into the vibe when I have a room like this. I really want everyone to feel seen and involved as much as I can
Funfact about an institutional environment I have worked in - a hospital psych unit. Many times individual rooms (specifically the locked rooms) would have individual water/sprinkler shutoffs for that specific room, because people would try to break the sprinkler heads. If someone did, staff could isolate that specific room from the system and prevent the doors from unlocking. Though an alarm would still sound and security would still have to attend the room.
wow fascinating... where were the shutoffs? out in the hallway? manual valves or electronic somehow?
@@DeviantOllam There was a service closet directly next to each of the secured rooms - staff could shut off water, sprinkler, power, and access a cleanout for the drains so all that work could be done without entering the room. The closet contained manual valves. The staff station also included a water shutoff electronic button, but I dont believe that affected the fire sprinklers, just the washroom.
When occupied, the rooms had to be constantly monitored by a staff member who would have a key to open those closets.
Police department cell blocks have a similar issue, as matches and lighters are relatively easy to smuggle in. I have worked with a customer that installs Marioff Hi-Fog systems in institutions like these. Instead of traditional sprinkler heads, they have solenoid-controlled valves that pump out mist that is supposed to both reduce water damage and allow creating buffer zones to trap smoke particulate.
I wrote a valve control app that runs on a touchscreen computer in the CCTV control room. When a fire detector is triggered, the traditional backup fire alarm system defers the general alarm for a short time while our software commands valves open in affected zones and lets security guards assess the situation. Valves can be both shut and opened remotely and the pump can be stopped in case the valves are stuck open. The final backup shutoff is the manually operated gate valve in the pump room.
So, if you ever get too drunk in $EU_COUNTRY, get thrown in the cell and see a fancy sprinkler system, don't try to trigger it. You'll only end up getting wet.
@@nyandyn that is truly fascinating and I've never seen that before, indeed!

Hi! I'm a former water-based fire suppression system technician. In regards to water companies shutting off the water, *most* places have a domestic service line and a fire service line, both tapped from the under-street water main. If you don't pay your water bill, the domestic service line gets shut off. Your faucets stop working, your showers stop working, but the fire risers remain in service. There's very few instances in which, unless the huge city main is disrupted, a fire riser will lose water. Even abandoned buildings with sprinklers will have water service to the riser(s) in most cases unless, say, the system is activated by vandals or scrappers and the fire department cuts off the service at the main riser gate (OS&Y) valve. There's of course exceptions to this in rural areas where water isn't provided by a waterworks, or cities and such where age is a consideration, but even in hundred year old buildings on the Hudson, *most* buildings with sprinklers have a water line for people and a water line for fire protection piped separately off the water main or tapped *before* the domestic service meters and shutoff.
I don't know anything about the law when it comes to payments or domestic water service and I imagine it varies *wildly* from jurisdiction to jurisdiction, but there's a prevailing wind of "I don't care how much they owe you, unless it's impacting the health or ability of others to have safe drinking water, if the building's occupied, you give them water. Sue them if you want the money" and I think that's a good thing.
Feel free to ask me anything about sprinkler systems, and if I know the answer I'll be happy to help!
That's so cool to learn about, thank you!
it happened at the building i work at. The pressure in the water main was cut by the city. The city turned the water back on during a saturday afternoon and SURPIRSE! Sprinklers went off in the boiler room, elevators flooded.... A year later there is a company in the building now going through every floor testing pressure.
1:02:12 I’ve got a funny anectdote for this, I was working in the back room at a Lowe’s when my manager came over with a forklift and one of the new employees. The employee said “I wasn’t aware that was an emergency exit” and the manager replied “Do you think something like painting a yellow box on the ground would help identify it as such?”. The new guy said yes at which point the manager used the forklift to shift a pallet out from in front of the emergency exit revealing the bright yellow painted box on the ground.
hahaha perfect
Sent this to some NFPA guys, the NFSA, and some companies in the industry. Thanks Deviant, you're one of the best, seriously.
i can't wait to hear what they reply. they'll catch some of my small errors! (like delayed egress... i said 30 seconds or 60 seconds, that's incorrect... 30 is the maximum allowable. 15 seconds is much more common)
@@DeviantOllam I play DND with a former NFPA guy, so I'll see him this Friday. Codes dense and has changed a bunch over the years. It's one of those ones where if you're just reading the updates like patch notes, it's not too bad but getting into it is rough.
I have an amber light that I got off a truck at a salvage yard. Don't need the cord, just chopped it off and can magnet it to the truck whenever I need to park somewhere unauthorized froa few minutes. Kick on the hazard flashers and go about my business. I already drive a white pickup, and a few magnetic " This vehicle makes frequent stops" or Speed monitored by GPS, a yellow vest on the passenger seat, hardhat and a lunch bag...no one will bother you.
The magnetic door signs are good...but if you want to go all out, buy a used Cricut vinyl cutter and make yourself some FakeCo. door decals. They look authentic and remove easy enough if you don't leave them on too long. You can even pre-make them and put them on a rental if needed.
When you hit your big box craft store, looks for PSV ( pressure sensitive vinyl). You don’t have to buy Cricut brand and usually something is on sale.
Also, they have 2 varieties usually. One is “Permanent” for vehicles, water bottles, that stuff. The Semi-Permanent is
usually for wall decals and things you really need to be able to peel off. This will safe uncomfortable explanations to a rental place later.
Tip: also buy the clear transfer vinyl. It’ll save so much time trying to line up the pieces later so long as it lined up in the software. 🙃
@@coffeegonewrong you can also weaken the adhesive using talcum powder.
Also, what if you Turtle Wax the truck first? If the decal is not actually stuck to the clearcoat but has a sacrificial layer in between, you should always be able to remove cleanly without harsh solvents.
@@JohnDlugosz and if you dont know where to get talcum, baby powder is the same stuff just with perfume added (at least the brands i used)

What kind of trouble can a building owner get into for violating fire code? Well quite a lot over here in NL.
I used to rent an apartment from one of the largest estate companies in the country. One day I couldn't exit through the fire exit like I normally did, so I had to walk the 100+ metres to the central hall in order to get out of the building.
So I checked the outside, as it turned out the outside of the fire exit has a key hole that my key would open. However it was only half a cylinder in the lock and the inside was just a blind, no way to unlock the door. Turns out residents of the building, including those on the ground floor, could lock the door from the outside with their key and then it couldn't be unlocked from the inside.
I called my boss to tell him I'd be a little bit late that day and proceeded to call the fire department. They sent an inspector out to me, we walked the building and it turned out that each of the 14 fire exit doors had this issue and 4 or 5 of them were at that time locked from the outside. Suffice to say the inspector was not impressed.
So he did the sensible thing, called some of his colleagues in other municipalities. They discovered that this method of saving a few euros on half of a lock cylinder was pretty much in every building that estate company owned.
So the inspector called up the estate company, had them send "someone in charge" over to my building and told them in no uncertain terms that they had 48 hours starting the following morning at 6am to get ALL of those doors sorted and up to code. Failure to do so would be met with a 1500 euro fine per door per day that it wasn't in compliance.
It took the estate company close to a month to fix thousands of doors, it cost them close to a million euro in fines.
They never replaced the half-cylinder locks, as that'd be too expensive. They just send maintenance crews with axle grinders to cut the deadbolts off. Making the doors self closing, self latching, but no longer lockable.
That's honestly really disheartening to hear. The fact that nothing really got fixed makes the fine seem so pointless. Just the cost of doing business.
@@eminatorstudiosHow is that not fixed? The fire exits became compliant. The company got a stern lesson in doing things right the first time.
@@henrikoldcorn Here in the U.S., "cut deadbolt off with angle grinder" is not an approved field modification and would void the assembly's listing.
@@uzlonewolfthe door opens, doesn't it?
@@thewhitefalcon8539 And where is the documentation stating that it has been tested in the new configuration and will open under conditions found in an emergency? Testing and certification by organizations such as U.L. and TÜV are required for a reason.

I will absolutely never use this information professionally, but it will forever sit in the back of my head from now on as I inspect every door and all fire hardware I see to someday find one egregious enough to contact the AHJ
You said people would be asking a whole bunch of questions, but not that it all would be actuaally amazing questions
Diesel engine pumps are connected to an external water source (large tank) designed to run until total destruction if need be. It’s also double redundant (2 starters and 2 battery sources). I used to work on them and they’re badass. Also usually the company that services the generator (Cat Cummins etc) services the fire pump.
Canadian Generator mechanic here: That's called Chicago Protocol up here and some places do use it. Unfortunately a lot of places here still have engine protection shutdowns because they're allowed to... Absolutely stupid to me. If that pump is running it's because it HAS to, and in my opinion they should run until they melt or seize if necessary. We have some big holes in life safety legislation up here.
@@cwjsmit64 maybe it might be advisible to make sure that the emergency water supply doesn't become a fire hazard by itself.
Oh hell yeah, two straight hours of conversational style infodump on safety codes.
I love how fluid and engaged this whole talk is 😁
Thanks again for making sure it was recorded to be posted online Deviant
Great talk!
I used to be front of house manager in a large museum with a conference centre attached, so I've seen just about every possible way of defeating fire safety provisions anyone has ever come up with. Events staff using a fire exit corridor as a storage closet was a classic, personal favourite was probably when I saw a fire extinguisher missing from its hook, went to look for it and found it propping open a fire door.
But the most shocking example was when the museum converted a basement into a brand new flagship gallery (cost in the milliions, fancy architects, etc) and then decided it needed a new gift shop kiosk just outside the gallery entrance. Fine, but then someone (not the architects clearly) OK'd converting the bottom of the stairwell into a stockroom.
Apparently nobody realised this was a no-no and I was the first one to express any sort of concern!
In the end the "fix" was to designate that stairwell as "not a fire exit" which meant we had to reassess all the building capacity numbers and redo tons of signage, rework our evacuation sweep routes, and on busy days, monitor the visitor numbers in one half of the building to ensure we didn't go over capacity. Absolute nightmare for such a stupid reason. And not even worth it since they ended up closing the gift shop kiosk after the first exhibition because it didn't even take enough money to pay for the retail assistant staffing it.
"No exit through the gift shop."
Fire saftey while doing dishes, noice.
I'm 20 min in and the audience is great. Really shows how valuable inperson shows are.
Checked into a hotel tonight, saw a door stop wedge holding a rated fire door open, got to apply this knowledge to bore a hotel clerk into fixing it.

Lol, in the spring, I saw some things that seemed off to me at my university. So I read the NFPA 101 and IFC fire codes and sure enough they were violations. Reported it to our fire and life safety department, fixed same day. I might also be a bit autistic 😅

This might just replace your adult industry talk as my favorite Dev' talk.
Adult industry was so great because it was clearly designed for a specific audience. Those were always my favorite essays to write in school, thinking about what to include for the target audience, what wording to use, etc. That talk was a masterclass of the genre.
Turns out with this speech that you also have a target audience: nerds. We all get super excited about connecting dots between disparate fields, like security and safety. You rocked the room.
Adult industry? Like adult film? Trying to think of how he would consult for that lol
@@ZMacGregor yes. it was a talk about physical and digital safety at a PH run conference. The overlap between people providing film services and people providing in person services is narrowing, you might follow someone on OF then meet with them IRL, maybe at a hotel, maybe at a personal residence. What's the security like? Hey, just so you know, under door tools exist! EXIF data exists on photos, too, so be careful with what data you are leaking for creepers to find you.
Dev is all about threat modeling. Adult industry people have threats, and that talk walked through how to think about and respond to them, and he did it in a very empathetic and competent way.
@@ZMacGregorAdult film stars are much more likely than the average person to have some creepy stalker try to break into their house or place of work, and the sets they work at probably aren't that well secured. IIRC Dev's talk focused on ways to prevent creeps from getting places you don't want them.

I was walking through an art museum in St Petersburg, prior to the Russian invasion of Ukraine. There was a bunch of people crowded around a Leonardo da Vinci. I glance over, and there on the wall is the Shits On Fire Yo painting, being completely ignored. It was the highlight of my trip.
I wish Old Rat sooner goes to Hauge.
The thing about murals, it's semi common in some institutional environments (think dementia wards) get exemptions to disquse the doors to prevent residents getting fixated on the exits. They get exemptions based on having procedures to assit and flashing lights on the exits.
I strongly recommend pairing this video with your favorite mid shelf bourbon and Deviant’s video on elevators
I'm happy that friendly, open and interesting people like you exist :)
i'm happy that this makes you happy 😊
@1:00:40 this reminds me of the Shmoocon 2019 party where the fire alarm went off and hotel security (Hilton, again, heh) wouldn't let people take their drinks outside, which caused back-pressure on people trying to evacuate, leading to a *very* slow evacuation... Something like >10 minutes to get everyone out, while it only took 90 seconds for everyone to get back in once the all-clear was given
i remember that. i definitely took my drinks outside, stiff-arming hotel staff in the process. they have absolutely no authority to prevent free movement of people during an emergency situation.
That was not a good look.
5-over-1's are actually specifically a weird edge case in the fire code - the ground floor is ordinary or noncombustible, and then the upper 5 stories are a combination of engineered wood beam (similar fire performance to timber framed) and normal wood stick construction. Essentially a 5-story apartment building made out of wood, sitting on the roof of a strip mall. They're basically firetraps compared to what you'd expect a 6 floor mixed-use building to be, and exploit the edge cases in the fire and building codes to enable cheaper construction. And they look pretty dang fireproof at ground level.
Seems like it's literally class5 OVER class1 😊
@@andrewmurschel2608it is also 5 stories over 1 story by coincidence
@@thewhitefalcon8539 Pretty sure it's normally 3 over 1 in terms of stories. It annoys me too.
For anyone who hasn't seen it, it's worth looking up those photos of a room burned to an absolute crisp, and everything outside of the door is fine.
We think a door, especially a wooden one, isn't going to do much against a fire. Makes it a bit hard to internalize all the advice about checking for smoke under the door, or not opening the door if the handle is hot. But wooden fire doors are no joke. Doors will save your life.
The talk was great fun! But also, it's cool how we're all going to be paying a lot more attention to doors as a fire safety device.
Please please please tell that to the fine folk on the second floor of the apartment building I used to live in. They always jammmed the door labelled "FIRE DOOR; KEEP CLOSED" open.
Right. When people tell me my battery box has to be metal, I just point them to the fire rating of oak plywood. (it would take hours for a fire to get through. li-ion battery fires only last minutes. much of what you see in yt videos is the other things it sets of fire... carpet, tires, etc.)
I have an answer to your question about missing bottom rods as a building maintenance technician. They get broken and are too expensive to replace. People running carts into them is most common. Far too many of our doors have received field expedient LBR conversions, with varying degrees of success.
Hey Deviant, I've worked at a place that had a sauna. The sauna had an entry area outside of it with a door to close it off from the rest of the hallways, and the engineers didn't do preparation for the heat in that area. The 155 f burst soon after the place was up and running. The building had that sprinkler trigger, and had to replace it with a green one. Thought you might get a kick out of this!
I swear this dude works a crowd so well! I've watched so many of Deev's presentations on "dry" topics and it never feels slow or uninteresting. I can imagine these conversation skills could only help when doing pentesting :)

Absolutely ELECTRIC crowd for such a dry talk. Only Deev is capable of such things. Genuinely excited for the paint drying (and whisky tasting) seminar. With a bonus story about how deev broke into a building by pretending to test for proper latex content in wall paint ((Non occupancy spaces may be litigated differently)ask your AHJ)

Okay... your comment made me giggle.
My old condo building learned about triggering an alarm by opening a sprinkler the fun way. One of our neighbors had an upstairs neighbor playing loud EDM into the small hours of the morning. He started pounding on his ceiling with a broomstick, and hit the sprinkler head. Those evacuation alarms are VERY loud.
I learned today that I want to be a code enforcement official. I enjoyed this way too much.
You also can bore people to death with your copy of NFPA 70 (edit: I appended sn E in error, it's just 70) the National Electric Code. I'm an electrician and physical plant mechanic.
I work in access controlled facilities. Some are tied to fire suppression, some are not. I also have fail-secure doors that won't open from the outside even in a fire. So, in less modern structures where the old code is grandfathered in, don't assume anything. I work in facilities from the 19th century to today.
Sorry to be pedantic but NFPA 70 is the National Electric Code, NFPA 70E is the "Standard for Electrical Safety in the Workplace". 70 is the code your electrical installation must conform to, while 70E is about safe work practices for keeping electricians safe on the job.
@@HOLOGRAPHICpizza My bad. I have been doing continuing ed on arc flash prevention, risk assessment, LOTO, and PPE. I have 70E on the brain. Also haven't been sleeping great and some of my gaffes are the product of insomnia. You are correct.
As a cybersec personnel, this talk is full of pristine hacker energy and I love it!
Also @deviant, in my experience if you experience a water loss on a charged wet pipe system IT WILL trigger a "Low-pressure" alarm on the newer systems and on older systems it generally does trigger a full alarm activation. Thanks
yes, an alarm activation... but it can't cause a release from the sprinkler heads
@@DeviantOllam It can if it's a deluge type. (personally never seen such) I've seen just such an activation due to an ice storm power outage. It was overflowing the stand pipe turning the parking lot into a skating rink. While I was in the building (telco), I didn't have access to dismiss the alarm. (facilities moron has to get there to do that.) I did climb the 9 flights of stairs to confirm there was no fire on the 9th floor. (there were no secondary alarms, so relatively safe to venture up there.)

0:10 you put an 8 hour talk on youtube with a bunch of stories, I WILL WATCH IT.
The podcast "Make No Law" (Can't recommend enough, only a few episodes, does great storytelling around major 1A law cases) has an episode talking about the trope of "Fire in a crowded theater". As a lead in to your Theater Fire segment it would be cool to see a slide talking about the trope before going in to how horrifyingly real theater fires were in the early 1900s.
In the discussion on fire sprinklers your slide showed varying size gas bubbles in the liquid. "Ordinary Structures" had the smallest. It would be interesting to see how big of a gas pocket higher temp bulbs have! Also, definitely don't hang clothes in them. My brother-in-law did that flooded his second storey apt's bathroom pretty badly.
I'm disappointed Group H wasn't "Hotels, Motels, Holiday Inns" huge missed opportunity.
Holy shit I miss Mitch.
I drank more as the talk went on (definitely not noticeable in critique length). I loved it. Thanks for continuing to share your knowledge and expertise freely Deviant. You rock.
Quite the most outstanding comment of this length that I've read in a while! Have an internet award! 🏆
For real, though, you really were hanging on to every detail and that's really cool!
I've never seen the ultra high sprinkler bulbs, myself... Sure would like to!
(Also, your Rapper's Delight reference there gave me a huge smile!)
Remember folks, it's only illegal to yell "fire" in a crowded theater if there IS NO FIRE. If there actually IS a fire in a crowded theater, it may be considered the appropriate course of action depending on the situation!
Literally minutes after hearing you talk about the Iroquois Theatre I see it listed in my Fire Officer text book while studying.
Awesome talk and wonderful you included all those questions! Excellent as always, Deviant.
I can't believe I just watched a 2-hour powerpoint presentation and liked it. Great video!
I can say from experience, loss of water pressure/supply due to shutoff in response to a main break can/will set off the alarms on the standpipe. A small business I used to work for had exactly this happen. The owner who lived down the street got a call around 4/5am from the fire alarm company letting him know that either the water was disconnected or the sprinklers were going off. This resulted in a 50-something year old man running, in sweatpants and a t-shirt down a Boston street in winter.
don't industrial extinguishers usually have pressurized systems with check valves to prevent backflow? water stagnates in these systems, I wouldn't want any of that feeding back into my drinking water
@@TheAechBombIt might depend on how old the fire suppression system is. Boston has some of the oldest still-in-use buildings in the U.S., so there’s a lot of places where stuff’s been grandfathered in past multiple code changes.
@TheAechBomb yes, but even installed new, they are allowed to lose some pressure over time.
I was clicking around for instant gratification on a Saturday afternoon...amazed I spent 2hours riveted the entire time. Well done!
I love all the little privacy redaction details. Delivering to Your Mom at 50:50 got me good
I work for an engineering firm. It is AMAZING what a hardhat and clipboard does to get you access. And some engineering companies are lazy. They put the door power supplies above the lay-in ceiling above the UNSECURE side. Mag locks, cut power. Electric strikes, a quick jumper to the low voltage power supply to open. All you need is a screwdriver, a bit of wire, and something to stand on. And there are a lot of ladders in the typical building.
Sounds like something an intruder wouldn't have time to do.
And a four foot ladder makes you look the part of maintenance
@@thewhitefalcon8539 What intruder? "I am here to do a take-off for the proposed renovation.". And they step aside.
Just FYI, Halon was almost entirely replaced with Halotron (at least in motorsports environment), which is less shitty for the environment.
A common one for telecom and datacenter goes by the trade name SAPPHIRE, it’s meant to be non-conductive and low cleanup. Also supposedly only mildly toxic until heated. When it encounters fire it’s best to clear the area but you can survive accidental discharges. ( this anecdote was from an fire system installer about his own personal experiences)
All the motorsports I'm aware of use AFFF. (non-PFOA/S that shit's been banned for decades.) It's still water based, so not a great idea around powered systems. (eg. data center.)
Commercial aircraft also sometimes will have water fire extinguishers as well as the Halon. If you see a gray fire extinguisher, that's a water based extinguisher.
I didn't even notice the time stamp. I saw Dev had a new video and it was about fire code - I just clicked it.
On the matter of vehicle cleanliness - no matter how dirty we field guys got, we were always expected to keep our work trucks (aka our “rolling billboards”) clean and presentable, especially if they were newer. The public may not see us working, but they sure as hell see the trucks.
The former firefighter/paramedic and current security enjoyer in me very much enjoyed this presentation.
Awesome talk as always. A little anecdote in reference to the section around 50 mins with fake service vehicles. I know a guy who got lost and ended up in a "secure" area at Pratt & Whitney, he had a silver Jeep with a Whelen light bar on the roof he used for roadside assistance. He made a wrong turn and security waved him right through a security checkpoint. He was trying to find the way out and started seeing "Restricted Area" signage...
He was helping block traffic at a wreck with that same vehicle one time and cops put a guy in his back seat thinking it was a patrol car. He had a net behind the front seats to hang stuff on and they apparently thought it was a cage. Never underestimate what you can get away with when you drive a plain vehicle with emergency lights.
1:39:00 that burning-through door - worth the whole 2 hours just to see that. Imagine being in that room with literal hell trying to get at you. Fire safety training for employees and students should include that clip. They should show it in public schools.
I can't believe this doesn't have more likes, this is one of the most fascinating videos I've ever watched.
Little-known fact. Per the NEC, you are allowed to wire a fire suppression pump and fire alarm systems directly from the supply side of the electrical system. That means no breaker. Fire pumps still need to have a service disconnect somewhere, but the point is, on fire pump systems if you turn off all the breakers, the pump and alarms may still have power.
Our lady of the angels fire was another terrible one in Chicago that led to better code around fire doors and stairwells.
This crowd was awesome, love the energy
Brilliant talk. Didn't expect to hang on every word of a talk about fire codes but here I am 2 hours later!
Question at 25:00. Dry pipe systems rely on compressed air to hold the water back. if the compressor looses power, the air pressure will eventually decrease in the pipe, allowing the water to overcome it, and flow into the formerly dry pipe. This will trigger a sprinkler flow alarm, but will not cause water to discharge form sprinkler heads.
Are those systems using a compressor constantly or are they just pressurized and then left standing?
@@DeviantOllamDry systems typically have a standby compressor to maintain pressure. There is a pressure switch that monitors the system and cycles the compressor when needed.
"A little obsessive, a little non-neurotypical..." 😭I'm being called out here!!!
Great talk, as always!
Thanks for an awesome talk. I'm in the door&windows manufacturing, and still i learned a lot from you.
Another cover story you might want to try / research is an environmental engineering technician conducting a Phase 1 Environmental Site Assessment.
1. My building is testing fire alarms while your premiere runs, coincidentally.
2. I learned that the countdown sequence you picked wasn't custom-made by the music label I thought made it for their concert premieres 😮
This was so fun to listen to. I thought I'll watch a couple minutes only, but stuck around for the whole thing
hah, my talks can be like that, lol
Two things...
One, regarding the 5 over 1 thing. You clearly need to be introduced to "Well There's Your Problem", a podcast about engineering disasters. With slides.
Two, motion for all future Deviant Ollam talks to be at the end of the conference!
I have that episode downloaded!
This talk was fantastic in person and nearly as good via video. Well done and thank you!
So glad you got a lot out of it! 😁👍
As a fellow neurospicy, that was one of the most interesting talks I've seen in a long time! I'd been interested in this kind of stuff but I realize just how little I know! And it's only making me want to learn more. Stay safe, and carry on!
15:00 Thank FDR for those changes, And many more of compassion, the best president that ever lived
Technology Connections sent me! 😊
Same, and not knowing anything going in I keep wondering what is going on with all of the "infiltrate this place and look like you belong" parts of this talk. I'm super entertained but also a little concerned lol
First time I learned about pressure/flow alarms on fire systems was at work, the county water system had a problem resulting in pressure loss and there was some kind of "back-flow" from the fire suppression system setting the alarms off. I'm told back when the building was constructed there were also issues with pressure changes at the top of the hour a huge number meetings ended and most of the toilets were being flushed at the same time caused enough of a pressure change to set the fire alarms off. Apparently they had to put in some kind of additional check valves or pressure tanks to help it absorb sudden changes.
I thoroughly enjoyed your talk. I was a firefighter for 20 years and knew a lot of what you were talking about and you made sprinkler systems fun! I took a college course that made me want to knaw my arm off and beat myself silly for signing up for it. I also got hurt on the job and became disabled so I went back to school to get my degree in Network Security and Social Engineering was one of my all time favorite classes. Thank you for your videos I am already watching another one. Stay Safe!
i absolutely LOVE how eager both you, and the audience are to talk here-
the whole talk sofar, like everything ive seen you do
has an incredibly wholesome vibe with how happy you've been to engage with the audience
Dev, thank you for that impressive talk - and you know what!? Having your own (original) pages in the video is SOOOOOO good! Even in Europe this is interesting :D
1:00:15 When I was in college, my dorm was set up so that at the bottom of the stairs, your turned left into the lobby and then went out the main doors. To the right of the stairs was a set of fire doors with the typical alarmed push bars. It was astounding how many people would turn left when the fire alarms were going off cause instead of taking the shortest path out. One RA actually tried writing up the smart ones who used that door for setting off the door alarms.
1:40:14 "this is what we do as fire door inspectors"
I see you've already internalized your new persona, well done
One of the best talks I've seen, period. Thanks for making these topics fun!
"Not about all the puppygirls out there." Deviant, holy fucking shit.
1:22:00 Pro Tip: All autofocus sucks. If you are in an autonomous filming situation such as this, *always* manually set focus during your setup, and then *turn off* autofocus.
My phone autofocus has a terrible habit of turning itself back on. I really need to learn how to actually lock it because you're right.
finally got a chance to watch this video. I love your talks and can listen to you and your stories for hours and hours. Thank you.
Id love to see a talk where you have nothing prepared and just let the audience ask questions that remind you of good stories for 3 hours.
I could do that. Like an Evening with Kevin Smith
I have a suspicion that the difference between group I and group R for elder care is related to whether it's assisted living, memory care, or independent living. People in an assisted living environment ought to be allowed to get out on their own, but they may not be capable of doing so for medical reasons. Whereas people living in memory care may be capable of leaving but generally wouldn't be allowed egress without staff accompanying them for safety.
Then independent living is a lot like a big college dorm for seniors.
