Description
An emergency blanket, often referred to as a space blanket or survival blanket, is a crucial component of first aid and survival kits. They are made from thin, lightweight, heat-reflective plastic sheeting, typically Mylar (metallized polyethylene terephthalate or MPET), which was originally developed for NASA to protect spacecraft and equipment from extreme temperatures in space.Here’s how they work:
- Heat Reflection: The metallic surface reflects radiated body heat back towards the user, helping to minimize heat loss and maintain body temperature.
- Weather Protection: Emergency blankets are designed to be waterproof and windproof, offering protection against rain, snow, and wind.
- Reduced Evaporation: They also help reduce heat loss by preventing sweat from evaporating, which can lead to rapid cooling.
