After Rademann, a safety officer showed us how to use the Dräger Oxyboks self-rescuer, a device that came in a small, frail-looking aluminum case. Self-rescue was not an idea I had grappled with, and now that I was forced to, did not like. In an emergency, you were supposed to open the little case and inflate the rubber bag inside by blowing into it, then strap the bag into place like a gas mask. The device would filter out toxic gases. It would keep you alive for 30 minutes.
