Paul DeBartolomeo shows the various components of airbag systems and how to test the setup before use.
I'll -- the -- column now welcome the training minutes it today's segment we're gonna discuss the components of -- high pressure air bag system. We're gonna demonstrate how to probably put the system and service. How to properly set the pressure and how to test the system prior to use. The foundation of any airbag system is the air source itself commonly in firefighters -- an SE BA cylinder. Other alternatives. Is the air brake system off of an apparatus. And -- court -- foot pump. Well we could even get air out of a rate higher using it tired shock -- out there. Are regulated consists of high pressure in Latin -- high pressure gauge a low pressure gauge. The pressure regulator -- The in line shut off in the low pressure -- -- All hoses are reinforced rubber three eighths inch diameter. High pressure hoses they operated 300 PSI. They come and various callers and -- The -- links. Are snapped lot with a twist. Safety for the -- once safety rating. A controller consists of the inlet valve. Yeah activation buttons it's a -- that -- control. The green all bought and supply in the bag while the red dog buttons the -- the back. Each each independent size has its own -- This controller has built in pressure relief -- If the pressure in the bag reaches greater than 118 PSI the relief valve automatically kicks and to prevent -- over inflation of the back. The outlet ports is where our supply hoses going to the controller in run to the bags and our air bags are constructed of reinforced and -- green rubber. With Kevlar reinforced the red. They have a non slip surface and are all marked on both sides with a large ax -- helps and centering the bags. One on top of the other when we stacked bags also helps us the -- a bag under a load we want always lift off the Senate -- back. The bags common sizes that range from one point two times to seventy -- and are capable of lifting a load from three to one inches. And -- some commonly used adapters and airbag systems all the -- shot off now. This is simply a device that allows us to shut your source off from the back so that we could remove a -- is if we needed that hosts to -- -- back. It'll allow the bag that we're using to stay inflated. Another common adapters the watch. When we applied as wide and control that we can run two separate -- wolf the same outlet this allows us to do a nice even balance -- Applying to wise to a controller allows us to -- -- back simultaneously. Now we're gonna demonstrate how to probably set up the air -- system. The first annual auto insurers that the shuttle off on the regulators in the off position prior to supplying regulator with there. Poking the regulator uses cylinders very similar to changing out a cylinder on an SE BA simply -- the high pressure coupling on those cylinder. When supplying the regulator -- air do so slowly. As an -- -- out that he diaphragm inside the regulator. As the system -- up you'll see the high pressure -- doctor rice. It should read the same -- the gauge on the cylinder. If these gauges fall below two -- PSI it's time to change out the cylinder. Next we want to set the regulator pressure 235. PSI we do that by turn of the controlling knob clockwise. As we aren't we see the -- on the low pressure dial -- to come up. Many times what we know is will put a white or red mark right on the -- itself out 1352. When -- we have the right pressure. Our next step would be to connect the supply hose from the cylinder. To the control. -- connecting these soldiers you wanna hear the -- snapped and you wanna -- down the safety collar. At this point we would turn the in line -- on the regulator itself. To the open position. This applies the controller with there. The simple test to ensure that we have air we're beating the press both the -- activation buttons when we do that we see. The gauge dial up. We can relieve the air by pressing the down bought. Now we want to move on to supplying our backs. Again we take our supply post. Into one of the outlets listen for the click. Screw the collar off -- we take the female -- It applied to the airbag didn't let nibble again we want to hear the snap. And we want to -- down the safety now. At this point our system is set up and ready for service. What we want to do now -- tests to make sure that everything's working properly. -- testing the system we really don't need to inflate the bags and more than thirty PSI. What we're simply looking to do always listen for any leaks are fine any defects within the entire system we simply -- -- press the up button. We see the -- start to inflate. We know the system is working properly the controllers supplying air in the hoses are getting -- the back. This point want to listen for any air leaks or any other problems that -- arrives. If we didn't -- that week we take a spray bottles of soapy solution. Sprayed in the area we bought the -- was in order to determine what the problems. Once we're done with this we simply make the -- we know the system is working properly. Were ready for service. In any fire department operation. Having pre determined riding assignments -- -- equipment allows for a quick and efficient operation. Many companies have designated assignments for air -- operations. In my company the outside -- firefighter is assigned to control operator positions. This assignment tasked him with transporting the equipment to the scene setting the system up and operating the control. As you can see our air bag system is -- wrecked we've conferred an old SE BA and have the regulator birdie attached. We have a large satchel. Which contains -- controller are hoses and -- most widely used fittings. And I most commonly used airbags the twenty -- air bag in the fifteen ton -- had been supplied with. Carrying straps so basically this system could be transported to the scene by one -- by. -- -- -- -- -- -- now thank you Washington.
