  • Keeping warm

In the event of a sudden disaster, such as a snowstorm, which causes a sudden loss of temperature, the first aid blanket can be fully expanded to wrap the body as tightly as possible, minimizing the part of the body exposed outside the blanket and waiting for support from the rear.

When camping in cold areas, you can also put the first aid blanket into the sleeping bag, and also put the first aid blanket under the sleeping pad, both can play a certain warm effect. But be careful to stay away from the open flame, because it is combustible, too close to the open flame will burn and easily cause damage.

Because the first aid blanket is mostly gold, silver, orange and other eye-catching colors, it has a good reflective effect and light radiation, which can make the first aid personnel find you quickly in the wilderness. There is also a tactical concealment color, mostly green, which is easy to hide in the outdoors and prevent wild animals from finding you.

Even if a 200-pound person lies flat on the unfolded first aid blanket, the four corners of the blanket and the middle of the blanket edge are picked up by six people at the same time and will not be broken. However, this kind of stretcher is only a temporary measure for short distance use, and it should be operated synchronously to avoid tearing and injuring the patient.
