The concept of an emergency space blanket is rooted in the fundamental principles of thermoregulation and heat retention. In situations where individuals are exposed to extreme environmental conditions, such as hypothermia or dehydration, the ability to conserve body heat becomes paramount. Emergency space blankets, also known as space blankets or emergency blankets, are designed to provide a lightweight, compact, and efficient means of retaining body heat in emergency situations. These blankets are typically made of a thin, metallicized plastic material, such as aluminized Mylar or polyester, which reflects radiant heat and minimizes heat loss.

History and Development of Emergency Space Blankets
The development of emergency space blankets dates back to the 1960s, when the United States National Aeronautics and Space Administration (NASA) began researching ways to protect astronauts from extreme temperatures in space. The first space blankets were designed to be lightweight, compact, and highly reflective, with the ability to retain up to 80% of radiant heat. These early blankets were made of a thin, aluminized Mylar material, which was found to be highly effective in reflecting heat and minimizing heat loss.
Materials and Construction
Emergency space blankets are typically made of a thin, metallicized plastic material, such as aluminized Mylar or polyester. These materials are chosen for their high reflectivity, lightweight, and compactness, making them ideal for use in emergency situations. The blankets are often constructed with a thin, breathable layer of material, such as polyester or nylon, which helps to minimize heat loss and prevent moisture buildup. The metallicized layer is typically applied to the surface of the blanket using a process known as vacuum metallization, which involves depositing a thin layer of metal onto the surface of the material.
| Material | Reflectivity | Weight |
|---|---|---|
| Aluminized Mylar | 80-90% | 1.5 oz/sq yd |
| Polyester | 70-80% | 2.0 oz/sq yd |
| Nylon | 60-70% | 2.5 oz/sq yd |
Applications and Uses
Emergency space blankets have a wide range of applications and uses, from outdoor and wilderness survival to emergency response and search and rescue operations. They are often included in first aid kits, survival kits, and emergency response packs, and are used by outdoor enthusiasts, such as hikers, campers, and skiers. These blankets are also used in medical settings to help regulate body temperature in patients, particularly in situations where hypothermia or dehydration is a concern.
Emergency Response and Search and Rescue
In emergency response and search and rescue operations, emergency space blankets are often used to help keep victims warm and dry. They are particularly useful in situations where victims are exposed to extreme temperatures, such as in cold weather or water rescue situations. By providing a lightweight and compact means of retaining body heat, emergency space blankets can help prevent hypothermia and dehydration, and can be a critical component of emergency response and search and rescue operations.
According to the National Weather Service, hypothermia can occur in as little as 30 minutes in cold water, and can be fatal if not treated promptly. Emergency space blankets can help prevent hypothermia by providing a means of retaining body heat, even in extreme environmental conditions. In fact, a study published in the Journal of Wilderness Medicine found that the use of emergency space blankets in wilderness survival situations can reduce the risk of hypothermia by up to 50%.
