Survival Myths and Misconceptions (Space Blankets)

Most survival publications recommend we carry a space blanket as part of our emergency kit.  If the space blanket fulfills the role of an immediate action shelter (IAS), we need to evaluate it as such.  

The seven requirements of an effective IAS (introduced in our last post:)

1. Compact:  Roughly the size of a deck of cards. (+)
2. Quick to deploy:  Difficult to unfold, especially with cold hands. (-)
3. Waterproof:  Only as long as you can keep your head, torso, bottom, and legs covered at all times.  Add injuries or wind this is impossible. (-)
4. Windproof:  Same as #3. (-) 
5. Traps heat: Not enclosed, it cannot maintain dead air space. (-)
6. Durable:  Shreds with the slightest tear or puncture. (-)
7. Brightly colored:  Under certain conditions, can be an effective signaling device. (+/-) 

When evaluated with these requirements, a space blanket clearly fails as an IAS.

Instead, we recommend carrying a blue, 2-mil, 78 gallon plastic bag as your IAS.  This is the same IAS used by our Department of Homeland Security, Search and Rescue and EMS clients.
