I got grease injected into my hand trying to grease a kingpin on a Jeep pickup. The owner was a regular customer and the left side was always difficult to get to take grease. I was using an air operated greaser with a compounding gun that multiplied the pressure when the handle was released and squeezed again. The tip wanted to pop off the fitting so I held it with my hand and the hose blew shooting grease in near the base of my thumb. They didn't seem to know what to do at the emergency room and were going to send me home. I had read an article about a man who lost his left arm after injecting undercoating into a finger while trying to clear a tip. I told the emergency room staff and they found a doctor who was familiar with injection cases. He showed up and told me that immediate surgery was required. I was in the hospital for 3 days with IV antibiotics. I have about a 3 inch long scar in the palm of my left hand, but I still have the hand.
Most hospitals have zero idea what to do with high pressure injection. Our hospital went through training because of the high pressure hydroblasting that happens in the area.
Happened exactly the same way with a friend of mine, he got a hydraulic injection when a hydraulic pipe broke on a tractor and got an injection in his knee. They cleaned it up at the ER and got some of the oil out then sent him home. When his wife, who is a nurse, came home saw it she rushed him back to the emergency room. They had to do extensive surgery on the knee to get all of it out. Luckily the knee was saved so he can walk even run albeit with some discomfort.
That's crazy that they were just going to send you home... We learned about how dangerous injection injuries are during my college program which included a hydraulics course

How large opening did your valve have? It might generate quite much pressure loss already over that. I think best/worst case would be damage some hoses slightly and then pressurize them until they burst. I got terrified already on the first video with that grease gun and pressure meter going all the way over. I have been somewhat afraid of injection injuries already long time but couple years ago we had 44 000 psi pressure washer for videos and I did some research for that project and saw some unpleasant stuff :D

@@dankeebler6171 They're working with a tube something like 8"/20cm in diameter, so 40,000 times the surface area of the largest hole here. And since they don't have reservoirs the size of a house, they have a very limited time to raise pressure and a limited reservoir of air. Different constraints. Here you can see the pressure drop even at normal speed, so the constraint is at the nozzle rather than at the target. There, the transient pressure spike is extremely short in duration, so getting the most energy out by using a fast-opening valve is crucial.
Arggggghhh... Bad memories! I almost lost a finger last year from a High pressure injection injury I got from an airless paint sprayer with the tip reversed so it sprayed out in a fine jet. Spent a week in the hospital and a had my hand sliced open and the bones scraped of paint. Still hurts, can't feel my fingertip and can't close my hand. Be careful people, if it wasn't latex I'd be done.
One of my mates lost a thumb when a hose split on an airless sprayer. They later took his index finger off and attached it as a thumb and made it work.

I've heard superheated steam is really scary. Invisible. Walking around the boiler room looking for the hiss, and suddenly your skin's being boiled/blasted off
HPHT steam... anyone that's been on a nuclear powered navy vessel knows about it. And a leak is a terrifying thing - but sleeping under the pipes as they run around under the flight deck is the worst. You just have to hope you won't even feel it if one pops a leak...
I’ve seen on a channel somewhere before that a Navy sailor posted a story about a high pressure steam leak. In the Engineering space around a new engine of some sort they have a protocol that you instantly freeze in place and don’t move until it is determined that you are safe. I don’t know what the details are, but like a lost Army Butter Bar with a Broken compass. A newly released ID10T was ignoring the order and he found the leak. Cut him clean Half in two within feet of the bulkhead door. Bad way to go ...
My first job was on a power plant and there was a rack of broom handles at the bottom of the stairs to the control room. When I asked why, the guy showing me around too a handle and waved it up and down in front of him as he went up the stairs. About 2/3 of the way up, as the broom handle got to about 5' off the ground, the top 6" just fell off. There was a high pressure stream leak and the operators used the broom handles to locate it so they could duck under it on their way to and from the control room. It had been that way for weeks. Fortunately, it got fixed the next day, but it scared the crud out of me.
Hey Ave, you should put a UV/near-UV blocking filter in front of the camera. That way you'll only pick up fluorescein fluorescence, giving you much more contrast.
Seeing 10k psi jetting into an apple absolutely terrified me and made my whole body tingle. You really don't think about this sort of thing most of the time. These systems are often closer than expected. My old Citroen BX car ran about 2500psi in the high pressure system for suspension and brakes and I frequently worked around it without giving it a moments thought. Also my old Silverardo ran something like 5k psi on the fuel injector at idle, both these would give you a very bad day if there was a minute leak.
@@bosstowndynamics5488 Lots of pressure and tiny holes. I'm just not sure how deadly diesel would be, since apparently the big problem is the zinc in the hydraulic fluid
It's like this big pressure tanks you never imagine how much power there is when the regulator flies off until you see it fly through a solid brick wall 5 feet away without even slowing down
Had a friend walk by a hydraulic line with a pin hole. Never knew what happened and has a spot in his arm a bit bigger than a golf ball that had to be debrided.
Not two weeks ago, I said I would never buy that battery operated grease gun. Today standing in the blazing sun around 1:30 at 35c plus the humidex, putting the track back on a mid sized excavator I was reconsidering my stance on that thing. I only use an air grease gun in the shop, and my truck doesn't have on board air. Nobody was around to help me load a decent compressor so I grabbed the Honda generator and a small pancake compressor. Took 5 times as long to tighten the track as it did to get it back on the machine. The last bit of tension took forever, and of course no hand grease gun in the 100 thousand dollar machine. Maybe one more team red tool wouldn't hurt. She might put out even more pressure with a HO 6.0.
This looks like an interesting torture device. "Tell us who you work for or we'll release the schmoo!" Edit: On a side note, common rail fuel injection on diesel engines can reach 30K PSI of fuel pressure. Don't check for leaks with your fingers!
You should always be careful with them, but realistically speaking they don't need much of an leak and that pressure is nowhere near what they're rated running in normal conditions.
Fun fact: Most places that sell "Ameraucana" chicks are actually just Easter Eggers, which is a mutt bred to lay blue eggs. Actual Ameraucana are very rare. Learned that first hand. Looking at you, Tractor Supply.
But seriously, I remember in the Navy seeing machinists swarm a high pressure air leak while waving sheets of paper at it. Looked like a congregation of shitty wizards.
As part of a health and safety training course, we were shown an injury to a fireman's hand from a hydraulic burst when he was training with the Jaws of life. They had to amputate.
Nice work! This is a great practical demonstration video. The risk of transdermal injection when working with high pressures doesn't get much mention, if any, and even when it does, the concept is abstract at best. The slow motion visualization really sends it home. Also, I think I'm going to suggest this video be played during our next pre-shift meeting, 1) for safety, and 2) because I work with a bunch of Canadians, and I wanna know who does and doesn't know who AvE is ... then judgements will be made!
Spread the word. Almost any town in North America has people working with high pressure fluids, especially hydraulics. Every class I’ve been to tells the horror stories and shows the pictures and tells us to insist that surgery be done
I worked as a greaser in an underground mine for about 6 months predating mech apprenticeship. I had a scare with a lever style grease gun. I was reefing on it trying to coerce a boom to bucket pin to take a bit of grease after the bushing was damaged/worn when the # 4 hydraulic hose extension I had on my grease gun blew a pinhole. I was wearing the thin nitrile coated gloves and luckily never had any injection but it felt like someone hit me in the hand with the tip of a slag hammer. You are probably onto something with the non newtonian thing. I pegged a 5k psi gauge almost instantly testing a lever grease gun, I’d bet they hit 10k no problem
Unless it is a trans-canadian chicken. New day, new way. We did not tell him he was a cock because we needed the eggs. "He's everywhere, he's everywhere "
Common rail can get up to 60,000psi. Working around those really requires gloves and a face shield. You also never run your hands over the lines or fittings unless you have already verified they are not under pressure. Use cardboard to check for leaks, just running the cardboard around will show you.
Every common rail diesel class I've attended has had this safety warning before/during/after class. Diesel pickups easily reach near 30k psi and even the gasoline direct injection cars are getting to +5k psi injection pressures.
@@BrandonJones-wv9mv gasoline is becoming the new diesel 40 years behind because of the so dangerous emissions of diesel engines. If it doesn't need spark plugs to ignite anymore, the process is diesel already
@@MF175mp i think only mass produced compression ignition gasoline engine is made by mazda and it still has spark plugs. Rest of direct injection gas motors still spark ignition. Also diesel is a fuel not an engine. There are turbojets that can operate on diesel fuel. Just like compression ignition Cummins motors could operate on cng or lp gas
@@VictorGalayda yeah but soon it may be mainstream and some will start removing the spark plugs as they would become useless. Rudolf Diesel invented the engine, not the petroleum product that only is named after the engine it's used in. Diesel engine can burn anything flammable from coal dust to crude oil if the proper injection system is added.
Went for some waterjet training last year. 50k psi through a .015 orifice. The horror stories of those injuries. Getting garnet surgically removed a foot away from where the jet pierced skin.
@@darkwinter6028 Most of my learning on tablesaws happened in highschool, where we had 3 of the industrial size SawStops, definitely reassuring. Obviously doesn't help if you get kickback, but I find it pretty easy to not have any particularly important parts of me in the line of fire, standing off to either side depending on width of cut
Thank you so much! This is so important. Ive only heard of the aftermath from hydraulic injection. More people working around hydraulic machinery need to be aware of the potential hazards. Shake hands with danger!
Man that brought back memories of doing wellhead. Using a Hy-Torq everyday and telling the green hats not to ever put your hand behind the wrench and always make sure your fittings are tight. I have seen hydro poisoning and man it is not pretty!
@@silent_bob_ the hydro wrench works by using hydraulic force pushing against another object (usually another nut and bolt) so you never put your hand in that space. Look up hydraulic torque wrench and you will see what I mean.
I've always wondered why all hydraulic torque wrench hoses dont have a clear plastic safety hose over them. Where as tensioning hoses do (specifically tentec). I've had tensioning hoses blow up around 24k psi and I'll tell ya, that external safety hose is a lifesaver. I'll never use bare hoses again.
Even when I was a little kid, dad would warn me about never putting my hands or any part of me close to pressurized hydraulic lines on the tractors. Expecially the old worn-out ones with no rubber coating left on them.
Someone told me about a worker who got hit with high pressure hydraulic, was a small hole in a hose, it shot into his arm, just a small puncture but he had to go into surgery to clean the inside of the arm, they had to open up the whole arm surgically all the way up to the shoulder. High pressure hydraulics are scary things!
I've heard stories of guys cleaning airless pumps with lacquer thinner after spraying with oil based and injecting their hands. Subsequently losing fingers at the minimum
We used vegetable oil in some hydraulic motors that were used for meat tenderising, they used to blow a seal and contaminate the meat with the oil the company used. They had the motor running to wrong way was the real problem causing the blades to bind into the meat. After we fixed it for them with swapping the pipes and using veg oil they gave us a bonus.
I would be curious to know how far away from the leak you need to be to be safe from injection. We have a LOT of hydraulic systems where I work, but inspite of having a very thorough safety program, we don't give much attention to the risk of hydraulic injection. I have not heard of many hydraulic injection injuries in steel mills, but then again we tend not to be right up against equipment while it's running. I would imagine that the oil looses it's velocity pretty quickly upon exit of the system. Would you by any chance be willing to shoot your schmoo at a greater distance? For science!?
@@-tr0n people have died from pressures air. Even had a case in my training where some guys thought they act funny and aimed the air hose at someones a hole and pushed it. Blew his intestines up. He has a bag now (edit : sounds like I made that up but no I didn't. Germany 2012)
I would assume that it looses velocity PRETTY fast, but its probably still dangerous at least within a few feet, but as pressure goes up and viscosity goes down, the danger goes up as far as danger distance goes. beyond a certain point the material comes apart and can't maintain its shape, or stream as it were, which really reduces velocity quickly. I'd guess that 5 feet you would be perfectly safe from injection from his rig.
@@kilianortmann9979 We used cardboard or paper for leak checking common rail stuff. Diesel injection pressures between 20,000 and 60,000psi. We were warned specifically in training to never put our hands near the lines unless they were dead and depressurized. Also best to wear a face shield when cracking lines. I've had several times gotten squirted at when opening up lines.
I'm an old salty dog of an offshore crane operator and all around bilge rat... Workin around the hydraulics of cranes/vessel propulsion/jacking system of liftboats in The Gulf of Mexico, we had regular training on the dangers of hydraulic injection injuries. You can walk past a hose with a tiny pinhole leak that you can't even see and it will cut you like a razor, injecting hydraulic oil inside your muscle fibers. The older gents spun yarns about walking around the boilers and engine rooms with a broom handle in front of them (like you do in the woods with a stick to knock down spider webs you can't see) and if the broom stick got cut or knocked around they would find the leak that way instead of bodily.... Training video aftermath examples were pure carnage.... Thanks a ton for the upload, AvE! VERY INTERESTING! P.S. Nice chicks! We are all looking forward to the Bumblefork episode where you demonstrate the proper technique for consumption of ones' own cock! XD
Remember doing some heavy rescue training and saw a photo of a hydraulic line that let go through some poor guys rabbit lined gloves. 16 surgeries later and the most horrific injury I’d ever seen. Almost threw up. Checked lines and connections EVERY time after that!
Though it feels like you’re releasing all those PSI’s all at once, the high speed tells all. You may be letting the pressure drop significantly because there’s much flow out of the orifice. Cheers from Southern Ontario
EXCELLENT VIDJAO! I work around high pressure, 10,000 psi plus, everyday. These young kids coming into the work force don't realize the danger aspect of this stuff. They think they are invincible. Again excellent. I would like to use this video as a safety reminder video since you have explained it and showed results of what can happen.
I don't mean to be telling tales out of school..... but has anyone ever seen AvE and Paul Harell in the same room at the same time... Just wondering....
I work with high pressure paint sprayers and the guy who had half his butt amputated for sitting on a armed gun still takes the trigger guard and nozzle guard off as soon as I give him a new gun..
Yeah, I remember seeing what high power hydraulic fluid does to a humans tissue internally. Typically that shit turns into little bb’s inside and causing immense internal damage to all the soft tissue under the dermis. Within 24 hours you begin to see severe swelling and pain begins to worsen, after 48 hours you’re in immense pain and if you haven’t already gone to the hospital you will be going by that time or you’re losing whatever was hit by the hydraulic fluid. I was taught to check for hydraulic leaks when I first started training for heavy equipment to use a stick to check the hose or area that we thought would be leaking or we would be likely losing a hand by results of the damage cause by high pressure hydraulic leaks. Yes, it absolutely will cause necrosis of the damaged appendage. This shit should absolutely be taken seriously as a warning to everyone, he’s definitely got some funny fucking commentary going for him but he’s absolutely fucking right, you can and will be seriously injured by fucking around with high pressure fluids in equipment. You never want to get injured by that stuff and all it takes is one mistake or a stupid act and you’re fucked in the most unhappy and painful way possible. He should show some demonstrations of injuries by hydraulic equipment like crush injuries. I had my arm crushed by my boss while I was using the equipment already and he decided to go mess with the operation station not checking for me when I had already told him I would be getting everything ready and to not mess with it without seeing where I was first. That injury was permanent as much as it was excruciating and I still feel it today.
I like the phallic demonstration the hose puts on whilst getting the schmoo primed at high pressure. Provides a great reference for a self test, checking all systems are operational. Now that’s the Cockford-Ollie!
Very informative video! If you think he’s kidding about the injuries, look up “hydraulic injection degloving” (only if you have a strong stomach). The victim NEEDS to go to the hospital regardless of what they say! We were trained to circle the injection site with a marker and write the time of injection next to it. This assists the doctors in deciding whether to amputate or not. VERY serious!
Reminds me if the time, when I was a kid, I got swiped by a pressure washer. Didn't look bad at first.. few minutes later water was "flowing" out if my skin... like it was pouring sweat. Then it turned pink.. liquid went from clear to yellow. Never bled a drop and had still a huge "nike swoosh" scar on my forearm for damn near 10 years. Damn glad it was tap water...
@AvE - I was skinning a sheep and nicked my pinkie finger on the joint. Cellulitis is BAD and spreads FAST!!! I ended up on serious antibiotics and still have issues over a month later...(Do not try this at home..)
Dang I feel lucky, two years ago I cut myself skinning a deer and about two months later cut myself skinning a pig. I just wrapped it in a paper towel and kept going
I remember safety videos in hydraulic class showing injection injury's, the oil is fat soluble and displayed pics of the doc scraping oil from the fat around some unlucky persons forearm
Good video, happened to "a buddy" with a pressure washer. Lost a chunk of the calf muscle the size of a golf ball...good thing it was JUST water I guess
Nice chicks! Thanks for showing this, I learned something very important. I work with hydraulic presses, and have only had some basic training. I knew that squirting oil at high pressure was dangerous, but I never thought about the injection - only the cutting!
In fact there still are stores like your Lees Electronics, just maybe not in Kanuckistan. Should you visit Singapore, go visit Koba Electronics in Peoples Park center. Paradise!
velocity is primarily dependent on pressure (theoretically). orifice geometry affects jet shape and is corrected with orifice coefficient. the experimental setup dynamics probably resulted in faster pressure loss with the larger orifice.
I’m a house painter. 20 yrs. the first thing learned about using a high pressure sprayer is to keep your stoopid meeathook away from the tip. Injection wounds may mean an amputation. This was an important lesson you shared.
I love the high speed camera porn soundtrack for the schmoo! But on a serious note when I set up the waterjet at work, it has all sorts of super scary warnings about high speed particles of sewage bacteria from normal water that can be injected because of the 60k Pressure. Different book, same story. Bad stuff.
Perhaps I'm just thick, but what about the original question? If you've got a pressurized system with no way to relieve it without you going in and manually loosening fittings how do you safely do that?
I THINK that not much happens when dealing with something as incompressible as grease. The pressure goes up AND down rapidly in response to available volume. Increase the available volume by 1cc and the pressure may drop to 5k PSI instantly. Add another 1cc of volume and be down to 2k PSI. Very rapidly you're at ambient pressure.
Long wrench and some rags around the fitting I suppose. That said if you're stuck in that corner a lot of thought should be applied to the problem as a whole, i.e. is that pressure holding something up/back?
I cringed at how painful that would be. One time I hurt myself with a pressure washer and it wasn't even a 1/5 of that sort of pressure... I was bleeding real bad
That shot at the end reminds of something. It's on the tip of my tongue. It's going to bother me all day if it's stuck in my head and I can't get it off.
Holmatro had an oil injection incident in Scotland. Bloke lost his hand/arm. Now with the core system the high pressure hose runs inside the return hose. And new Kevlar hoses can be kinked unlike the thermo plastic hoses.
You are amazing. I wish so bad that I could meet you some day. You remind of my dad that passed not long ago. You two would have been so happy to hang out. I can’t describe how awesome your videos are. It’s like being in the shop with pops.

Not two weeks ago, I said I would never buy that battery operated grease gun. Today standing in the blazing sun around 1:30 at 35c plus the humidex, putting the track back on a mid sized excavator I was reconsidering my stance on that thing. I only use an air grease gun in the shop, and my truck doesn't have on board air. Nobody was around to help me load a decent compressor so I grabbed the Honda generator and a small pancake compressor. Took 5 times as long to tighten the track as it did to get it back on the machine. The last bit of tension took forever, and of course no hand grease gun in the 100 thousand dollar machine. Maybe one more team red tool wouldn't hurt. She might put out even more pressure with a HO 6.0.
I routinely work on hydraulic systems, diesel engines, and other high pressure fluid systems. This is my number one nightmare.
“It was a bit more volume than I was expecting”. That’s what she said.
Hahaha
All the juice
We'll she's never said it... But I'm always hoping she will 😁
At his age he's still got it. Even I was impressed.
This looks like an interesting torture device. "Tell us who you work for or we'll release the schmoo!"
Edit: On a side note, common rail fuel injection on diesel engines can reach 30K PSI of fuel pressure. Don't check for leaks with your fingers!
Lol that's why they go through the hood if something is wrong
But thats how you really get diesel into your blood.
Deck Name Really? I guess I’ve been going about it all wrong.
**pours diesel/banana smoothie down the sink*
You should always be careful with them, but realistically speaking they don't need much of an leak and that pressure is nowhere near what they're rated running in normal conditions.
@@deckname5794 and diesel is the worst fluid of all for eating away at your flesh is it not? Or does it just get real deep!?
As an m+e engineer 2 things scare me hydraulics and the stroboscopic effect of rotational machinery.
I bruised a finger pretty good once poking an invisible spinning object... stroboscopic effect is definitely scary
As an avionic mechanic, well, shit, flare buckets, high voltage cabling, and 3000+ PSI hydraulics.
On airless paint sprayers, they actually have a warning card- surgeon advisory, in case you puncture your body and inject paint. 🤢
Another guy talking about how he almost lost his finger and had to get the paint scraped off his bones
Fun fact: Most places that sell "Ameraucana" chicks are actually just Easter Eggers, which is a mutt bred to lay blue eggs. Actual Ameraucana are very rare. Learned that first hand. Looking at you, Tractor Supply.
In the Navy we taught guys to look for HP leaks on energized systems with the straw end of a sweep 🧹.
Interesting, My dad was in the Air Force and told me he was taught to use the other end.
@@richardhunter607 are we still talking about checking for leaks?
But seriously, I remember in the Navy seeing machinists swarm a high pressure air leak while waving sheets of paper at it. Looked like a congregation of shitty wizards.
@@AuxiliaryPanther Yes I was talking about leaks, but I imagine he had plenty of experience using one for it's intended purpose.
Had some of the old BTs tell me of looking for leaks on the old 1200psi boilers with broom handles. When it got shorter you found the leak...
As part of a health and safety training course, we were shown an injury to a fireman's hand from a hydraulic burst when he was training with the Jaws of life. They had to amputate.
Nice work! This is a great practical demonstration video. The risk of transdermal injection when working with high pressures doesn't get much mention, if any, and even when it does, the concept is abstract at best. The slow motion visualization really sends it home.
Also, I think I'm going to suggest this video be played during our next pre-shift meeting, 1) for safety, and 2) because I work with a bunch of Canadians, and I wanna know who does and doesn't know who AvE is ... then judgements will be made!
I'm currently learning to be an emergency physician, this was pretty interesting to see, I'm glad I learned this
The world needs more emergency staff who are trained in industrial emergency situations.
Spread the word. Almost any town in North America has people working with high pressure fluids, especially hydraulics. Every class I’ve been to tells the horror stories and shows the pictures and tells us to insist that surgery be done
I worked as a greaser in an underground mine for about 6 months predating mech apprenticeship. I had a scare with a lever style grease gun. I was reefing on it trying to coerce a boom to bucket pin to take a bit of grease after the bushing was damaged/worn when the # 4 hydraulic hose extension I had on my grease gun blew a pinhole. I was wearing the thin nitrile coated gloves and luckily never had any injection but it felt like someone hit me in the hand with the tip of a slag hammer. You are probably onto something with the non newtonian thing. I pegged a 5k psi gauge almost instantly testing a lever grease gun, I’d bet they hit 10k no problem
The dye is likely fluorescein based on the color. It is dirt cheap (
Would you mind if i ask a couple of question about fluoreacent? I have a bit of an obsession in using it for art projects/crafts
@@saberxzero Sure, ask away. Hopefully, I can answer your questions.
Grounds Keeper Willy: ACK! Turn off the noozlel!

That last bit reminds me of a German movie I saw once. Maybe twice.
Pro tip:
The male ones don't lay eggs.
Not true, they lay double yolked eggs!
Explain this If the rooster didnt lay the egg.. how did his dna get in there
@@buddersthepuunk high pressure grease injection
Unless it is a trans-canadian chicken. New day, new way. We did not tell him he was a cock because we needed the eggs. "He's everywhere, he's everywhere "
Cant roosters identify as any gender they want these days?
There is real danger working on modern Diesel engines... the high pressure fuel systems are capable of 30,000+ PSI!!!
Common rail can get up to 60,000psi. Working around those really requires gloves and a face shield. You also never run your hands over the lines or fittings unless you have already verified they are not under pressure. Use cardboard to check for leaks, just running the cardboard around will show you.
Every common rail diesel class I've attended has had this safety warning before/during/after class.
Diesel pickups easily reach near 30k psi and even the gasoline direct injection cars are getting to +5k psi injection pressures.
@@BrandonJones-wv9mv gasoline is becoming the new diesel 40 years behind because of the so dangerous emissions of diesel engines. If it doesn't need spark plugs to ignite anymore, the process is diesel already
@@MF175mp i think only mass produced compression ignition gasoline engine is made by mazda and it still has spark plugs. Rest of direct injection gas motors still spark ignition. Also diesel is a fuel not an engine. There are turbojets that can operate on diesel fuel. Just like compression ignition Cummins motors could operate on cng or lp gas
@@VictorGalayda yeah but soon it may be mainstream and some will start removing the spark plugs as they would become useless. Rudolf Diesel invented the engine, not the petroleum product that only is named after the engine it's used in. Diesel engine can burn anything flammable from coal dust to crude oil if the proper injection system is added.
Went for some waterjet training last year. 50k psi through a .015 orifice. The horror stories of those injuries. Getting garnet surgically removed a foot away from where the jet pierced skin.
Yeesh...that's horrible.
That’s the other tool that scares the @$^%#3%&9& out of me. (first one is a table saw) 😬
At least with a waterjet, you know you need to go to tho ER because your pinky is bobbing in the tank.
@@darkwinter6028 Most of my learning on tablesaws happened in highschool, where we had 3 of the industrial size SawStops, definitely reassuring. Obviously doesn't help if you get kickback, but I find it pretty easy to not have any particularly important parts of me in the line of fire, standing off to either side depending on width of cut
Thank you so much! This is so important. Ive only heard of the aftermath from hydraulic injection. More people working around hydraulic machinery need to be aware of the potential hazards. Shake hands with danger!
thanks for watchin', keep you chicks in a box.
ahahah missed opportunity :D

Made my wife Coq au Vin and she loved it. She asked what the name meant and i told her it was her two favorite things.
Wine and Au?
Cock with wine.. I prefer to use chicken.
Man that brought back memories of doing wellhead. Using a Hy-Torq everyday and telling the green hats not to ever put your hand behind the wrench and always make sure your fittings are tight. I have seen hydro poisoning and man it is not pretty!
Sorry not a native English speaker: What do you mean by having your hand behind the wrench? What do you mean by behind?
@@silent_bob_ the hydro wrench works by using hydraulic force pushing against another object (usually another nut and bolt) so you never put your hand in that space. Look up hydraulic torque wrench and you will see what I mean.
I've always wondered why all hydraulic torque wrench hoses dont have a clear plastic safety hose over them. Where as tensioning hoses do (specifically tentec). I've had tensioning hoses blow up around 24k psi and I'll tell ya, that external safety hose is a lifesaver. I'll never use bare hoses again.
I don't miss using Hy-Torq's especially getting in well cellars. I did wellhead for 5 years for Cameron.
@@yotafan174 I'm more of a rad gun type of guy. Unless they wont fit, then I'll jump to hytorq's stealth heads
I just want to say that you make excellent and informative videos while also being uniquely hilarious. Keep it up AvE!
That's a morning after stream. Either sit down or aim for the tub.
Or just go outside lol and hope the wind is favourable
😆😆😆
Even when I was a little kid, dad would warn me about never putting my hands or any part of me close to pressurized hydraulic lines on the tractors. Expecially the old worn-out ones with no rubber coating left on them.
After 6 months stuck on a mine in the DRC I also have blue eggs
Some of the blokes are busy developing a bit lopsided especially their right biseps.
Someone told me about a worker who got hit with high pressure hydraulic, was a small hole in a hose, it shot into his arm, just a small puncture but he had to go into surgery to clean the inside of the arm, they had to open up the whole arm surgically all the way up to the shoulder. High pressure hydraulics are scary things!
Steam too
Lots of pictures on Google, pretty sure one was a firefighter using a rescue cutter or similar, pin hole in the hose.
I've heard stories of guys cleaning airless pumps with lacquer thinner after spraying with oil based and injecting their hands. Subsequently losing fingers at the minimum
We used vegetable oil in some hydraulic motors that were used for meat tenderising, they used to blow a seal and contaminate the meat with the oil the company used.
They had the motor running to wrong way was the real problem causing the blades to bind into the meat.
After we fixed it for them with swapping the pipes and using veg oil they gave us a bonus.
I would be curious to know how far away from the leak you need to be to be safe from injection. We have a LOT of hydraulic systems where I work, but inspite of having a very thorough safety program, we don't give much attention to the risk of hydraulic injection. I have not heard of many hydraulic injection injuries in steel mills, but then again we tend not to be right up against equipment while it's running. I would imagine that the oil looses it's velocity pretty quickly upon exit of the system.
Would you by any chance be willing to shoot your schmoo at a greater distance? For science!?
@@-tr0n people have died from pressures air. Even had a case in my training where some guys thought they act funny and aimed the air hose at someones a hole and pushed it. Blew his intestines up. He has a bag now
(edit : sounds like I made that up but no I didn't. Germany 2012)
Usually I think it's inches. But in certain cases I've heard people say it can be dangerous from several feet away.
@@mfk12340 hardly depends on the nozzle size
I would assume that it looses velocity PRETTY fast, but its probably still dangerous at least within a few feet, but as pressure goes up and viscosity goes down, the danger goes up as far as danger distance goes. beyond a certain point the material comes apart and can't maintain its shape, or stream as it were, which really reduces velocity quickly. I'd guess that 5 feet you would be perfectly safe from injection from his rig.
@@kilianortmann9979 We used cardboard or paper for leak checking common rail stuff. Diesel injection pressures between 20,000 and 60,000psi. We were warned specifically in training to never put our hands near the lines unless they were dead and depressurized. Also best to wear a face shield when cracking lines. I've had several times gotten squirted at when opening up lines.
I'm an old salty dog of an offshore crane operator and all around bilge rat... Workin around the hydraulics of cranes/vessel propulsion/jacking system of liftboats in The Gulf of Mexico, we had regular training on the dangers of hydraulic injection injuries. You can walk past a hose with a tiny pinhole leak that you can't even see and it will cut you like a razor, injecting hydraulic oil inside your muscle fibers. The older gents spun yarns about walking around the boilers and engine rooms with a broom handle in front of them (like you do in the woods with a stick to knock down spider webs you can't see) and if the broom stick got cut or knocked around they would find the leak that way instead of bodily.... Training video aftermath examples were pure carnage.... Thanks a ton for the upload, AvE! VERY INTERESTING!
P.S. Nice chicks! We are all looking forward to the Bumblefork episode where you demonstrate the proper technique for consumption of ones' own cock! XD
"They" fear the indoor chicken farmer
Any sane chick would be afraid of schmoo at that pressure.
Remember doing some heavy rescue training and saw a photo of a hydraulic line that let go through some poor guys rabbit lined gloves. 16 surgeries later and the most horrific injury I’d ever seen. Almost threw up.
Checked lines and connections EVERY time after that!
Though it feels like you’re releasing all those PSI’s all at once, the high speed tells all. You may be letting the pressure drop significantly because there’s much flow out of the orifice. Cheers from Southern Ontario
I knew it :) new video states that lauri from hydraulik press channel made the same comment
EXCELLENT VIDJAO! I work around high pressure, 10,000 psi plus, everyday. These young kids coming into the work force don't realize the danger aspect of this stuff. They think they are invincible. Again excellent. I would like to use this video as a safety reminder video since you have explained it and showed results of what can happen.
I was wearing my AvE carefulling T-Shirt watching this and nothing happened to me!
That just means you didn't try hard enough.
That means it works! Scientific method, right there.
Full marks for correct spelling of carefulling, unlike the T-shirt.
But did you have safety squints on?
I love Lee's Electronics. you always come out with more than you needed.
Where's the meat target?

Don’t talk about his better 3/4 like that... 😀
I enjoyed the four and a half minute ad for Nordlock. Learned a bit.
I work with high pressure paint sprayers and the guy who had half his butt amputated for sitting on a armed gun still takes the trigger guard and nozzle guard off as soon as I give him a new gun..
Never stop making videos my friend. If for no other reason, my enjoyment. Thank ya!
Yeah, I remember seeing what high power hydraulic fluid does to a humans tissue internally. Typically that shit turns into little bb’s inside and causing immense internal damage to all the soft tissue under the dermis. Within 24 hours you begin to see severe swelling and pain begins to worsen, after 48 hours you’re in immense pain and if you haven’t already gone to the hospital you will be going by that time or you’re losing whatever was hit by the hydraulic fluid.
I was taught to check for hydraulic leaks when I first started training for heavy equipment to use a stick to check the hose or area that we thought would be leaking or we would be likely losing a hand by results of the damage cause by high pressure hydraulic leaks. Yes, it absolutely will cause necrosis of the damaged appendage.
This shit should absolutely be taken seriously as a warning to everyone, he’s definitely got some funny fucking commentary going for him but he’s absolutely fucking right, you can and will be seriously injured by fucking around with high pressure fluids in equipment. You never want to get injured by that stuff and all it takes is one mistake or a stupid act and you’re fucked in the most unhappy and painful way possible.
He should show some demonstrations of injuries by hydraulic equipment like crush injuries. I had my arm crushed by my boss while I was using the equipment already and he decided to go mess with the operation station not checking for me when I had already told him I would be getting everything ready and to not mess with it without seeing where I was first. That injury was permanent as much as it was excruciating and I still feel it today.
this is why lockout tags and isolation switches exist. and if its a plugnplay device, remove the plug and she wont play.
I like the phallic demonstration the hose puts on whilst getting the schmoo primed at high pressure. Provides a great reference for a self test, checking all systems are operational.
Now that’s the Cockford-Ollie!
I think citrus fruits might be best for simulating skin. Tattoo artists practice on grapefruits. (Also, hydraulic injection has always terrified me.)
Very informative video!
If you think he’s kidding about the injuries, look up “hydraulic injection degloving” (only if you have a strong stomach). The victim NEEDS to go to the hospital regardless of what they say!
We were trained to circle the injection site with a marker and write the time of injection next to it. This assists the doctors in deciding whether to amputate or not.
VERY serious!
When that slow-mo music started playing I started bouncing catchy as f***
Reminds me if the time, when I was a kid, I got swiped by a pressure washer. Didn't look bad at first.. few minutes later water was "flowing" out if my skin... like it was pouring sweat. Then it turned pink.. liquid went from clear to yellow. Never bled a drop and had still a huge "nike swoosh" scar on my forearm for damn near 10 years. Damn glad it was tap water...
I tapped this accidentally but think I found a new great channel. Thanks for the great commentary!
@AvE - I was skinning a sheep and nicked my pinkie finger on the joint. Cellulitis is BAD and spreads FAST!!! I ended up on serious antibiotics and still have issues over a month later...(Do not try this at home..)
Dang I feel lucky, two years ago I cut myself skinning a deer and about two months later cut myself skinning a pig. I just wrapped it in a paper towel and kept going
I remember safety videos in hydraulic class showing injection injury's, the oil is fat soluble and displayed pics of the doc scraping oil from the fat around some unlucky persons forearm
"Pink Ladyyyy!" 5:22 Someone been taking notes from good old Bill Burr?
Thank you for the video. I am now officially scared shitless of anything with pressure ...Better that than experiencing it....

Love your videos !! Super applicable and educational! I'm father and I enjoy you fatherhood videos too!!
Good video, happened to "a buddy" with a pressure washer. Lost a chunk of the calf muscle the size of a golf ball...good thing it was JUST water I guess
Nice chicks!
Thanks for showing this, I learned something very important.
I work with hydraulic presses, and have only had some basic training.
I knew that squirting oil at high pressure was dangerous, but I never thought about the injection - only the cutting!
I still have a bunch of stuff in baggies from the old Lee's on Main St. The new location is pretty great too though, don't you worry.
To get the air out of the system just pump it until it starts to come out then close the valve and pressurize it.
In fact there still are stores like your Lees Electronics, just maybe not in Kanuckistan. Should you visit Singapore, go visit Koba Electronics in Peoples Park center. Paradise!
velocity is primarily dependent on pressure (theoretically). orifice geometry affects jet shape and is corrected with orifice coefficient. the experimental setup dynamics probably resulted in faster pressure loss with the larger orifice.
Drive a big diesel injector with it and show it on an apple 🍎 😁
I think this is far more important than the constant h2s lectures we get at work.
I'm curious about that background track. It reminded me of some later episodes of LEXX.
Me too... can it be found on Spotify?
Its Roots of a Legend by Jim Huerta, he does a lot of this kind of thing and you can find him here on YT too
Love your high speed camera tune. It's 80's-ish with a strong Napoleon Dynamite flavor profile.
Man I need to be more careful . I don't want to poke a hole in the back of my gals head .
you definitely released the schmoo in this video. i got dehydrated just watching it
Should fed the chica the oil apples too, that way your wings fry from the inside too! thats how we do it with our shrimp along the Gulf of Mexico.
Lee’s electronics is still by far the best nostalgic parts source out there. Can’t beat that smell!
"Why are you taking apples and a black light into the bathroom?"
"...youtube!"
I’m a house painter. 20 yrs. the first thing learned about using a high pressure sprayer is to keep your stoopid meeathook away from the tip. Injection wounds may mean an amputation.
This was an important lesson you shared.
I love the high speed camera porn soundtrack for the schmoo! But on a serious note when I set up the waterjet at work, it has all sorts of super scary warnings about high speed particles of sewage bacteria from normal water that can be injected because of the 60k Pressure. Different book, same story. Bad stuff.
Music choice and video second to none, as always.

Perhaps I'm just thick, but what about the original question? If you've got a pressurized system with no way to relieve it without you going in and manually loosening fittings how do you safely do that?
I THINK that not much happens when dealing with something as incompressible as grease. The pressure goes up AND down rapidly in response to available volume. Increase the available volume by 1cc and the pressure may drop to 5k PSI instantly. Add another 1cc of volume and be down to 2k PSI. Very rapidly you're at ambient pressure.
An apprentice
Long wrench and some rags around the fitting I suppose. That said if you're stuck in that corner a lot of thought should be applied to the problem as a whole, i.e. is that pressure holding something up/back?
The slow motion money shot at the end made it all worthwhile
AvE. So safety wise, never eat an apple around high pressure hydraulics! 😁
That's the true lesson here
I cringed at how painful that would be. One time I hurt myself with a pressure washer and it wasn't even a 1/5 of that sort of pressure... I was bleeding real bad
That shot at the end reminds of something. It's on the tip of my tongue. It's going to bother me all day if it's stuck in my head and I can't get it off.
It’ll eventually come to you...
Holmatro had an oil injection incident in Scotland. Bloke lost his hand/arm. Now with the core system the high pressure hose runs inside the return hose. And new Kevlar hoses can be kinked unlike the thermo plastic hoses.
You are amazing. I wish so bad that I could meet you some day. You remind of my dad that passed not long ago. You two would have been so happy to hang out. I can’t describe how awesome your videos are. It’s like being in the shop with pops.
