In this rapid intervention segment, Jim McCormack details the actions of the navigation-air supply RIT firefighter after the team has located the victim.
Okay what we're gonna go over this time is emergency air supply and again I'm gonna ask that you refer back to the segment on. -- positions and assignments this assignment is performed by the navigation -- supply person after they've found the victim. So stepping back a little bit and talking about emergency air supply we need this -- secure is supplied to this down five and we need to get him -- sometimes you may be running out or out. Where he may have some in there but you wanna addressed is supply function as soon as you can. There's a couple different options with the air supply first and foremost. Get yourself a -- to carry your emergency air supply in so that it sent -- the way you you're gonna perform when you get this down five. This three options -- look at when we talk about emergency air supplies to do that will look at the pack we have we've got this tax that up if we -- When the pack up. And take a quick look at the inside. Everything we need is right here that's why we've we've set this bag -- to function the way we would performance in a worst case situation. One of the first options available. To the firefighter on the inside. Comes from this -- a connection which is a high pressure -- -- device. That is attached to your -- act in all of -- -- -- packs out there if we take a quick look at it. They've got a -- a connection on that now some of the old pax don't but in all the conversions and all the new packs have this. An option to get this guy is simply to take that universal connection. Plug it into his universal. A connection on a step back in this -- -- fails so let's say this as zero. And this has 4500 rounds. We're -- equalize that twenty to fifty somewhere around that about it equalize prices the nice thing about this is that there's no compromise to the environment you simply give -- -- -- with a bit. One of the downsides to this is that when we talk about drags. You'll see that we could rip this off and it happens fairly easy so if you use this option you've got a lot it has built in and remove it. Otherwise what will happen is that you will. Rip this off and you'll have bigger problems on your hand so remember the pros no. No compromise of his they have supplied weapon on you may not be able to get through it if he was trapped on -- back -- you may rip it off if you forget to take -- out. That's one option. A second option that exists. Is the low pressure often and in this rip that we carry it with a low pressure regulator out -- and ready to be used. The firefighter who has this -- set up. Can easily be converted by swapping the regulator -- the benefit to this is is much more flexibility. And also it's it's probably the most common gloved hand action that U performance and individuals so you'd be pretty proficient at making this switch. The downside to this one is that -- compromising his they have supplies so you have to take the pros and the problems. And plug them into the environment that you have. Because this may be the only option that you canyons so that's option number two in terms of -- -- supplies. And the third option that exists which should be a definite worst case option. Would be a bit -- that this guy was in a packed unlike -- -- -- with no universal connection. War. He had his face mask compromise or ripped off completely and in that event what you would do. -- should come to -- written act which is carrying a spare face mask. And then make that set up. And then actually convert this face mask of the down -- dubbed the most difficult they have -- that that there is. But it's something that may have to happen and even if it's not happened with the rat pack you maybe dragon this guy out and somehow -- -- mask off. So you'll have to be proficient at getting a mask back on the down 50. So that's three options that exist a couple of things about the -- act we wanna talk -- -- Is when did turn it on it and what do you do after you've secured yes supplies so you turn the pack on on the outside simply -- check and make sure everything's in place. And then you turn it off and you only turn it on when you get to the victim because if you don't. What would happen is that if the bypass was opened slightly more than -- which happened to be activated you would lose all your -- and probably never know that by the time -- go to the victims Oprah and on outside jacket. And then actively turn it off so that you know you -- -- ago. And the last thing is once the F supplies been converted to this victim the firefight. We have -- Caribbean are attached to the bag in a drag strapped that we would simply attach to the converted waist strap of the victim. And -- it becomes a hands free operation you dragged the victim -- -- that's NBA strapped in this -- -- simply drag out with. So what we'll go in the next sequence here is we'll show you the actual connection to the down -- Based on whatever -- supply option you -- you would simply connect this is the last step. And then he would be rented have been in no. Okay the last step in the emergency air supply like we talked about is actually securing the bag to the down five remember unit used either the high pressure won the regulator or the face mask to convert his area. Now what you want to do is just take the bag. Get the -- -- attached to his crotch strap. And out no matter which drag technique you use. This is actually in street you can remove the firefighter in the bag is gonna simply drag right straightaway with him. That's a technique that allows you to focus -- removal. And not.
