What you are seeing here is the SCBA, or self-contained breathing apparatus. I have no idea how this acronym is supposed to be pronounced, but I’m assuming it is not like scuba (which is, in case you don’t know, an acronym for self-contained underwater breathing apparatus).
The SCBA is designed for firefighters, in order to help them breathe in rooms that are toxic with smoke. It can connect to a shoulder-mounted air-tank with a retractable air tube.
I have to admit that the SCBA looks much less burdensome than the ones I have seen on firemen. It also has a voice amplifier, so a fireman’s yell of “is there anyone in here” can be heard. It also has a flashlight, as well as a heads-up display.
It sort of reminds me of the mask that Liam Neeson wore when he played Ra’s al Ghul in Batman Begins. It also reminds me of the ones Han, Leia, and Chewie wore in The Empire Strikes Back when they had landed inside that huge asteroid. I always wondered about that scene. I mean, if they were inside an asteroid that they had entered in through a huge tunnel, then technically, they are still out in space, right? I would think they would need more protection than just something that looks like a gas mask. I guess George Lucas didn’t want to do that scene with head-to-toe spacesuits.
Anyway, the SCBA is simply concept for now, but I can easily see it on firefighters of the future.
