BLUE BOOK 7 — CAVE SURVIVAL ENVELOPE

This is the one that stops death from winning by default. When a victim is: trapped upside-down pinned in a choke point half-submerged losing oxygen going into shock dehydrating freezing suffocating under their own weight The Cave Survival Envelope (CSE) wraps around them and preserves life long enough for rescuers to reach them. It’s not a sleeping bag.Not a stretcher.Not a cocoon. It’s a micro-environment, a portable pocket of stability. A human terrarium that refuses to let the Earth take you yet.
