Emergency Thermal Blanket Facts

There are a variety of names – and styles – of thermal blankets. These are known as emergency blankets, first aid blankets, space blankets, weather blankets, safety blankets, Mylar blankets, shock blankets, or heat sheets. They are handy in many situations. Here are some interesting emergency thermal blanket facts.

  1. Thermal blankets are made of plastic, in a very thin sheet.
  2. Emergency blankets are coated with gold or silver colored reflecting agent, which reflects back radiated heat – up to 97%.
  3. These blankets are often included in kits meant for survival, first aid, and emergencies.
  4. Space blankets are given to athletes after their events. Sometimes they are given before the event, as well, if the weather is cool.
  5. Space blankets were developed in 1964 by NASA.
  6. Thermal blankets can be used to combat hypothermia, as well as to prevent it.
  7. Because they are so thin, thermal blankets are lightweight.
  8. Because they are plastic, often coated in metal, these blankets are also durable.
  9. Thermal blankets are waterproof.
  10. Emergency blankets are weatherproof.
  11. Most are made from Mylar designed by NASA.
  12. Most thermal blankets are three to five feet wide bysix to seven feet long, making it possible for nearly anyone to wrap up in one efficiently.
  13. A bit of tape can convert heat sheets into sleeping bags.
  14. Most thermal blankets are individually packaged for ease in carrying.
  15. Space blankets can deflect heat from the sun; however, this should be done from a bit of a distance, as using it close to the body will still reflect and contain body heat.

  17. Thermal blankets are windproof.
  18. It can be twisted and used for a tourniquet in an emergency.
  19. For someone lost in the woods, a thermal blanket is reflective, which means it can be used to signal for assistance.
  20. Wrap around items in a backpack to keep them dry in inclement weather.
  21. Because it collects and reflects heat, it can be used in a winter survival situation to melt snow for fresh water.
  22. Carry water with it by gathering the corners and sides, making a bowl shape.
  23. Its waterproof nature makes it usable for shelter; tie it, lean-to style, to a couple of trees.
  24. Written on with a marker, it can be used as a poster or banner.
  25. A small hammock can be made with a thermal blanket.
  26. Its durability means that it can be used to add to rope by twisting it and tying it together.
  27. Small pieces cut from a thermal blanket could be used as lures to catch fish, because they reflect. Fish enjoy shiny items.
  28. Reflect light to increase it; this can be done with a campfire, candle, flashlight, moonlight, etc.
  29. It can be folded and tied into a sling in a pinch.
  30. Pieces of a thermal blanket can be used as scrubbing ‘cloths’ for cleaning dishes or people.
