When choosing an emergency blanket, several key features should be considered to ensure it's effective in survival or emergency situations. Here’s a list of important features:
-
Material: Typically made of Mylar (space blanket material), which reflects up to 90% of body heat and provides thermal insulation. Some may have reinforced layers or different materials like polyethylene for added durability.
-
Size: The blanket should be large enough to cover an adult. Common sizes range from 52 x 82 inches to 60 x 84 inches. Larger blankets can cover multiple people or be used for shelter.
-
Weight & Portability: Lightweight and compact for easy storage in a backpack, first aid kit, or glove box. Most emergency blankets weigh less than 2 ounces and fold down to pocket size.
-
Durability: Look for blankets that resist tearing or puncturing. Some emergency blankets are reinforced with extra layers or coatings to improve their lifespan.
-
Waterproof & Windproof: Ensuring the blanket is resistant to moisture and wind is crucial for outdoor survival, keeping you dry and protected from the elements.
-
Reflective: Bright reflective surfaces increase visibility, which can aid in rescue operations by signaling to search parties.
-
Reusable vs. Disposable: Some blankets are designed for one-time use, while others are more durable and reusable, depending on your needs.
-
Multi-purpose Use: Emergency blankets can double as ground covers, sunshades, or temporary shelters. Some can also be used to create a makeshift sleeping bag or tarp.
-
Insulation Rating: Some emergency blankets have added features to improve insulation, like thicker layers or double-sided reflection, which can help maintain body heat more effectively.
-
Color Options: Silver is most common, but other colors (like orange or gold) may be more visible in rescue situations.
