Attention: Firefighters & Emergency Service Officers (ESO's).
In this video, Brian outlines 'How to Operate a Breathing Apparatus Open Circuit during an Emergency'.
There are several respiratory hazards involved in fire fighting due to HOTS, which are high temperatures, oxygen deficiency, toxic or poisonous gases, and smoke or suspended particles. In order to avoid injuries and to survive a rescue, you need to know how to operate a breathing apparatus. An open circuit set will pass expired breath to waste through an exhalation valve that comes with a face mask. It provides air, and its duration depends on the competence, fitness and mental state of the individual.
Parts of a Breathing Apparatus
There are different sizes, types and makes of a breathing apparatus. A typical BA has a cylinder, low pressure warning device, harness, pressure reduction valve, demand regulator, pressure gauge, head harness and face mask. The low-pressure warning device is designed to indicate when the cylinder has around ten minutes of air left. The remaining air is known to be a safety margin. The demand regulator controls the supply of air to whatever is required by the user during a rescue operation. One’s depth of breathing determines the rate of supply. The pressure gauge is connected to the cylinder through a high-pressure hose. It is made to indicate the pressure of the cylinder. Elements of a face mask include a full vision visor, exhalation valve, head harness, regulator, and a speech diaphragm.

Operating a Breathing Apparatus during an Emergency Situation
Before fire fighting operations, the fire fighter must do some checks to ensure that the breathing apparatus is in good working condition. You should place the BA on a clean surface. The first thing that you need to check is the cylinder and its band adjustment. Be sure to untangle all the harnesses, as well as the facemask adjustment straps.
You should also make sure that the cylinder hydrostatic test date is not due. You should depress the standby mode reset button and shut the constant flow valve. Then open the main cylinder valve and see to it that the cylinder pressure is above the minimum needed for rescue operational use.
Now close the cylinder valve and check the pressure. The gauge should not fall more than 10 bars over a minute. Check the operation of the constant flow valve by opening it to remove the pressure in the set. Once the pressure drops, check the pressure gauge and make sure that the low-pressure warning device is working at the right pressure.
You should test the Distress Signal Unit in all its modes. If you find any faults with the breathing apparatus, you should record it and report. If there are no faults then, it is fit for fire fighting duties.
There are four stages of operating a breathing apparatus during a rescue attempt. These are donning, starting up, closing down and doffing.
Donning
Donning is the phase where the individual puts the breathing apparatus on the back and do the preliminary checks.
Starting Up
During this phase, the facemask of the breathing apparatus is fitted. The final checks are made to ensure that the apparatus is working properly.
Closing Down
After the emergency operation, the breathing apparatus is set to standby mode and the facemask is removed.
Doffing
Doffing is the process of removing the set from the back of the wearer and prepared to be cleaned and placed in its storage place so that it can be used again in the next fire fighting operation.

my left ear really enjoyed this video
I always have my left one in and i just realized there is music in the left one
Same here
😂
very useful viedo and give me knowledge thanks
Nice instructions
thank you garret morgan for the invention of the gas mask
Nice
Sir I'm from India and I need your help regarding the Scaba (open ) how minimum pressure maintain in confined space ...and how to calculate the duration of uses in confined space .....
Pls help me
what
@@jimmyrecard6021 I WANT A HELP ON BA SET LIKE A TYPES OF BA SET MINIMUM REQUIRED O2 in confined space how much pressure gauge maintain
@@Safetyman2020 I can't understand you
@@jimmyrecard6021 pls make videos on BA set
@@jimmyrecard6021 - you are ignorant !!
You would check the gauge at the start. ? It would be pointless running through all these checks if there wasn't enough air available. It would waste valuable time taking it back off and putting on another B.A..
Luke Wright yes of course. From what I know you check your equipment every day and again on the way to the fire. The last check is for your own safety ( you dont say, all of these steps are for my own safety *facepalm* ) just to check if everything is really alright
Nice
When he checked the seal he already had it all on and he turned the entire SCBA off which is very dangerous. When I check my seal I do it when only the mask is on and cover the hole with my hand.
Collin Rykaczewski Holy cow! Thanks for this comment!
@@D_V_.746 _"why you are not completely screwed if the integrity of the mask is damaged whilst operating in a hazardous atmosphere"_ Sorry I'm late to the party, but I'm curious;
Is that because of constant over-pressure compared with the environment?
The way you explained it, I can't help but compare it to my CPAP/APAP device.
Constant pressure means the only air reaching my face is air coming thru the device (as long as it pushes, anyway. The mask has inward check-valves so I don't asphyxiate in a power outage).
Once the belt is connected i would tie/wrap up the loose part. It was hanging loose, that could cause a snag
Thanks, i need this for my drills 🙏
I have a question the bypass valve should be on or off during the use of the equipment? by the name bypass I understand that should be used in case that something is not working right. is this correct or wrong.
Thx!
damn!! this video makes me want to be a FIREMAN!!!!!!
Join the merchant navy use BA all the time
Join the navy. You'll be a firefigter
Or go to a VFD and be a volunteer
Are you a firefighter now? It's been 5 years now
another question one of my test question give me the option and i know it sounds but the oxygen tank is 50% full ? it doesn't make sense but I want to make sure I'm clear on that one.
Thank you I will be practicing how to don a BA set today at course. 😃
How much time to breathe you have with that on???
you guys are modern day heroes
RESPECT
you all probably dont give a damn but does anyone know a trick to get back into an Instagram account..?
I somehow forgot my password. I love any help you can give me
@Lance Adam instablaster ;)
I need this set up I'm installing cameras in a sewage plant next week, yuck, where can I buy this?
One Day I'd like to do My breathing apparatus course
"and placing it over my face ...mwhamphumwhwahpham whamphumwhwahphamwhamphumwhwahphamwhamphumwhwahpha mwhamphumwhwahpham whamphumwhwa hphamwhamphumwhwahphamwhamphu mwhwahphamwhamphumwhwahphamwhamphumw hwahphamwhamphumwhwahp hamwhamphum hwahphamwhamphumwhwahpha"
...and this is why people dont wear SCBA gear on the local news.
....why use the neck-strap, when you just can stress the regulator hose......!!!
❤❤❤
Great video but you could have done without the music.
Question
Why did he not know where the pressure gauge was right off the bat?
what would you say is the distance of the pyrex glass to your eye?
How much pressure gauge maintain for confined person
i want this mask..
why there is no sound only music
- via YTPak(.com)
Why do firefighters use gas tanks instead of a gas masks (filter)?
Because of temperature, and no filter can provide adequate airflow immediately while also safely filtering out everything.
Well done man
Great
I love this careers
Is the same air used in diving compressed in to these BAs?
up to a certain distance, at deep distances oxygen become toxic i believe, just search at what depth is compressed air safe underwater
66 metres (217 ft) Depth at which breathing compressed air exposes the diver to an oxygen partial pressure of 1.6 bar. Greater depth is considered to expose the diver to an unacceptable risk of oxygen toxicity.
Why do you have to turn it back a quarter turn? 1:40
you don't. Every service does things their own way mate.
The reason for this has to do with expanding values.... Things get hot they expand
For air conservation
Douglas Erickson no scuba divers also do a quarter back turn and there's no heat in cold lakes lol
Its to prevent it from seizing. You do the same thing with climbing carbiners
my dad was a fire fighter
Ok it's probably just me but don't you put your tan hoodie on first then the mask
It can cause leaks in the mask
You pull the hood over after the scba
Although it is recommended to put the mask on and the hood after, you can also have a good seal when the hood is on, before donning the mask. Just need to set the straps correctly.
Hood over mask straps or under mask straps, which is correct?
....face-mask straps always go under the flash-hood; the neck-strap is the only strap outside the flash-hood !
one thing stood out to me here, once opening the airflow from the cylinder, fully, he proceeds to close the valve by a quarter turn. I have never seen this, in my 2 years of HazMat / Environmental Emergency Response on the field. Even in my SCBA training, this is not something we do. Can anyone explain the reasoning behind this? Im open to taking on a new technique if its actually beneficial.
It’s to prevent backseating it’s applicable to most valves that prevents damage and possibly failure over time
To see if the pressure drops
It's also to check the pressure for fluctuations
