    Question Rescue breathing

    We had in house discussion today about rescue breathing for scba's. Which brought out a few different recomendations. I was wondering what your thoughts are and if anyone has any idea on the proper rescue breathing techniques that are being used?

    I'm assuming you mean "buddy" breathing. There are several ways of accomplishing this, our packs (Scott 4.5) have a buddy breath hose incorporated in the pack. Some other methods that are being taught by the PA State Academy are sharing a facepiece, sharing a regulator, breathing with your lips around the regulator, around the bottle threads, and staying low and cracking the seal on your facepiece and breathing through your hood.

    Question

    Ok...I can understand the sense in all of them except putting your lips around the bottle thread. If you do that, then obviously your bottle is not unattached from your harness. Thus you don't have the air flowing through low and high pressure regulators. So two points why I think that isn't the best thing to do:

    1) Your blasting a s-load of high pressure air into your mouth.

    2) Your wasting a lot of air that is in your bottle.

    If you wrapped your lips around the threads of a Scott 4.5 bottle, you wouldn't have to worry about buddy breathing, or even breathing for that matter. That's 4500 psi coming out of the bottle. More than 2 tons per square inch. You think your lips could handle that?

    All the methods mentioned will work to some degree, but all have their downfall and most a common downfall.

    Sharing a facepiece: Involves taking off your helmet and hood, making you very vulnerable to personal injury. Removing the facepiece subjects you to the exact toxins you are trying to avoid, again making you the next potential victim.

    Sharing a Regulator: In my opinion better than sharing a facepiece since your helmet, hood and facepiece stay in place for better protection. Still has that issue of subjecting yourself to the toxins of the IDLH atmosphere you are in.

    Mouth on the threads: It works, I've done it and tought it in my RIT class however it needs to be done with care due to the pressure. We use Scott 4.5's and if you have ever held the threads up to your facepiece without the regulator in place, you will see that the threads will fit nicely into the regulator opening. The careful part comes with opening the cylinder. You need the absolute smallest twist of that knob that will allow air to flow.

    All this being said, I think that it is rather easy to sit here and say do this, don't do that while sitting at your computer, but should you be the guy who's SCBA fails, you are probably going to do whatever you can to get air. With that said, as the 'buddy' remember that. If you pass off your regulator, you may not get it back do to the panic reaction of your partner.

    My best suggestion is radio your situation and position and escort your partner out ASAP. If you share your air, then you are depleting it twice as fast with 2 of you under panic conditions and then you still have to get out. Keep your air and your wits and get your partner out.

    If you are both trapped with no ability to get out, then all bets are off, sharing is just about your only option until someone can get to you.

    FF Trainer said it best, when you have to do this stuff, all bets are off. Give your guys the best chance possible, only purchase or retrofit packs with buddy breather options. Make sure your FAST company is standing by with a spare pack, make sure your guys know ALL of these little tricks, who knows which one will work? Here are two more. If you are alone and run out of air with a Scott buddy breather pack. Disconnect the fitting going to your mask and try to tuck the male end of the hose into your coat. It's very tough, but you might get some breathable air or try create a filter over your regulator opening. Use your hood (wet it if possible) in several layers to try to filter out most of the heavy particulates and cool the air a little. You will still take alot of the gases, but it may help. By the way, NONE of this will ever help unless you take the guys to a burn building and try it under some stress.

    Breathing from the bottle is very possible,as I've done it many times (only in training) As FFTrainer said, you only crack the bottle take a breath and close the bottle. I should have explained. Are these conventional methods...absolutley not! But they may just mean the difference between life and death. I strongly suggest you practice them. Take care.
