The Complete Handbook of Emergency Blankets

Emergency blankets save lives, but only when someone chooses the right one, deploys it correctly, and understands what it will and will not do. The shiny 5x7-foot sheet in your kit is not one blanket; it is at least four different products - metallized polyester, non-woven polypropylene, fleece-lined composite, and heavy-duty vinyl - and each performs differently in wind, rain, and subzero temperatures. Misuse is common: wrapping a hypothermia victim tightly in a vapor-barrier blanket can accelerate the chilling process by trapping sweat. This handbook replaces guesswork with engineering.

It opens with the physics you actually need: how radiant heat, conductive loss, and moisture management interact with metallic coatings and woven substrates. It then walks through every type on the market, with testable specifications for reflectivity, tensile strength, tear resistance, and packed size. Dedicated chapters cover selection matrices for specific roles (wilderness EMS, urban evacuation, mountaineering, film location first aid), step-by-step shelter construction, repair techniques using ordinary gear, and a practical maintenance schedule that extends the life of reusable blankets.

The final sections address the business side: how to evaluate suppliers, spot the difference between compliant and counterfeit products, negotiate bulk pricing, and build a profitable resale, rental, or private-label operation around a product that every organization needs but few understand. This is a working reference - the book you keep in the gear room, not on the coffee table.
