my question is, why are they doing this stuff on the ground and not off a truck? Wouldn't it make more sense to practice it from getting on a truck, putting the SCBA on and then getting off? I don't think you'd show up to a confirmed structure fire and grab the SCBA from the truck, throw it on the ground then open the valve. You'd get on the truck put it on, once you get to the call you'd obv get off it and get your line and then get to the front door waiting for water to your line and as your masking up then you open the valve. Why wouldn't you have the mask already connected to the regulator? saves you time in putting it on cause then you have to find the air hose and connect it whereas if you have it connected it's as simple as putting it on.
We have to lean forward and put scba on back from ready position. We have to tighten waist first before shoulders. We have to have gloves on before we put on regulator. Most of us have Scott's, so we have to push in and then turn while on back. This is alot harder than it looks
The last step is the first step. Check that the cylinder gauge is reading at or a above 2216 psi. If its not, a new cylinder will need to be attached. Check that the o ring is seated in its nut and is in good condition be fore attaching the new cylinder….. lol. UPS makes don and doffing more complicated than it needs to be.
Pure oxygen can be harmful, so it’s just pressurized breathing air. Basically, an air compressor takes in outside air, compresses it, and puts it in the tank.
It’s pressured air Closed circuit respirators have oxygen bottles, open circuit like Scott’s/msa and most all firefighting ones Closed circuit is a rebreather
This is SCBA ,self contained breathing apparatus ,fire fighters use it during fire fighting and rescue operations .this is full of fresh air for breathing in hazardous area , where deficiency of oxygen or pouisness areas
Good demo .But I have a point to share 03:40 Doffing SCBA .You are disconnecting the regulator with out removing the mask.It is not correct method .You will not get air to breath.
