Rescue blankets: Life savers in pocket size

In the world of survival equipment, rescue blankets stand as unobtrusive heroes. These thin, lightweight blankets can make the difference between life and death in critical situations. In this article we explore the different types of rescue blankets, their uses and how they work to protect you in emergency situations.

Background and history

Rescue blankets, often known as thermal blankets, emergency blankets, or space blankets, have a remarkable history that stretches from the space age to the emergencies of our time on Earth. Originally developed for NASA in the 1960s, these blankets were intended for use in space shuttles and satellites. They were designed to protect astronauts and their craft from the extreme temperatures of space, where they could reflect away the sun's radiation while retaining body heat in the cold vacuum of space. Made from a thin layer of plastic, often PET, coated with a metallic reflective material such as aluminum, these blankets combined light weight with effective thermal insulation.

After proving their value in the space program, the rescue blankets soon became available to the public and began to be commercialized in the 1970s. They quickly became a standard component of first aid kits worldwide, often used to treat or prevent hypothermia and shock in emergency situations. Their popularity also grew in the outdoors, where their lightweight and compact nature made them a favorite for hikers, campers and adventurers.

Over the years, the rescue blankets have undergone several innovations and improvements. Variations in material and design have been created to suit different needs and conditions. In addition to the traditional Mylar blankets, more robust versions have also been developed, such as wool-based blankets, which are more suitable for use by emergency services and in harsher environments.

Today, the rescue blankets are considered a basic element of safety and survival equipment. Their uses range from medical care to disaster preparedness and adventure sports. With a growing awareness of the importance of being prepared for emergencies, rescue blankets continue to play an important role in both professional equipment kits and personal safety kits.

What is a rescue blanket?

Rescue blankets, also known as thermal blankets, emergency blankets, or space blankets, are made of thin, reflective materials that aim to retain body heat or protect against heat radiation. Originally developed for space programs, these blankets have become a standard tool in first aid kits and survival situations.

Types of rescue blankets

Rescue blankets come in different designs, each adapted to specific scenarios and needs. The two main types most commonly used are Mylar blankets and wool-based rescue blankets.

Mylar blankets , also known as thermal emergency blankets, are made of a very thin plastic material coated with a metallic reflective layer, usually aluminum. These blankets are notable for their ability to reflect back up to 90% of body heat, making them extremely effective at preventing heat loss. They are waterproof, windproof and exceptionally light, making them ideal for emergencies, outdoor activities and as part of a survival kit. Their compact size means they can easily be stored in the car, backpack or first aid kit.

On the other hand, there are wool-based rescue blankets . These are much thicker and more durable than Mylar blankets and are often used by emergency services. They are best suited for situations where a robust and long-lasting heat retention capability is necessary. Unlike Mylar blankets, which are intended for single use, wool-based blankets can be used repeatedly and offer a higher level of comfort. However, they are significantly heavier and less compact, which can be a disadvantage in certain situations.

1. Mylar blankets (Thermal Emergency Blankets)

   • Made of plastic film coated with metallic material.
   • Light and compact.
   • Reflects up to 90% of body heat.
   • Waterproof and windproof.
   • Ideal for single use in emergencies and outdoor life.

2. Wool-based rescue blankets

   • Thicker and more durable.
   • Often used by emergency services.
   • Suitable for reuse.
   • Heavier and less compact.
   • Better for long-term use and higher comfort.

These different types of rescue blankets offer different benefits and are adapted to meet specific needs in different situations. The choice of felt depends on the area of ​​use, required durability and transport possibilities.

When and why to use rescue blankets

Rescue blankets are versatile and can be used in a variety of situations:

• Emergency situations : In the event of an accident or when someone is in shock, the blanket can help maintain body temperature.
• Hiking and camping : To protect against the cold at night or as an emergency solution if equipment breaks.
• In cars : An excellent item to have in the car's emergency kit, especially during the winter.
• Sporting events : Useful for marathons or other outdoor sporting events where weather conditions can change quickly.

How do rescue blankets work?

The basic function of a rescue blanket is to reflect the body's own heat back to the body. This prevents heat loss by:

• Reflection : The reflective surface sends body heat back.
• Wind and water protection : Dense material that protects against the effects of the weather.

How to use a rescue blanket

Before using a rescue blanket, it is important to understand some basic principles. First, rescue blankets are designed to reflect body heat. When using a Mylar blanket, it is important that the reflective side (often the shiny, silver side) faces inward, toward the body. This is to effectively reflect the body heat back towards the person.

If the blanket is used outdoors, it is important to protect it from wind, as strong winds can reduce the effectiveness of the blanket by blowing away the warm air that collects between the blanket and the body. In windy conditions, seek shelter or use the blanket indoors or in a tent.

As for wool-based rescue blankets, which are thicker and sturdier, they are more forgiving in their use but should still be kept dry and clean to maintain their insulating properties

1. Open Carefully : Be careful when opening a Mylar blanket as they can tear easily.
2. Correct Side Against the Body : Make sure the reflective side is inwards.
3. Protect from Wind : Use the blankets in a sheltered place if it is windy.
4. Cover the Entire Body : To maximize heat retention, cover the entire body, including the feet and head if possible.
5. Keep Dry and Clean : Make sure wool-based blankets are kept dry and clean for best performance.
6. Avoid Direct Contact with Hot Surfaces : Mylar blankets can melt on direct contact with open flames or extremely hot surfaces.
7. Reuse and Storage : Wool blankets can be reused if they are cared for properly. Mylar blankets should be folded carefully and stored in a dry place for possible future use.
