Thermal or emergency blankets (also called Mylars or space blankets) are thin sheets usually made of plastic, destined to keep you warm in bad weather conditions or in case of an accident. These blankets are extremely light and due to their material, they can keep about 90% of your body heat by not letting the warmth radiate away from your body. They are usually large, with high resistance to wind and water, and ideal for surviving in emergency situations as they reflect body heat and keep you protected from elements.
Unlike ordinary aluminum foil, this type of blanket is usually made from two layers and can be used repeatedly. Thanks to its bright color it can be immediately seen from a distance so you can use it as shelter when waiting for the rescue teams. There’s a very small chance to not be remarked by rescuers when you’re covered with it.
A thermal emergency blanket can be very useful when camping, so it’s always recommended to know what products are the best and why. One situation where the blanket might prove useful is when exploring a cave: the blanket is extremely useful in underground locations, for thermal protection of injured cavers while waiting for the rescue team.
It doesn’t weigh much, it can be packed easily and it fits anywhere, even in your pocket. This is why you shouldn’t forget to include it in your emergency kit and make sure you always have at least one to spare.
Multiple uses for the first aid blanket
Believe it or not, an emergency blanket can be used for various emergencies, domestic or outdoors. If you have one around the house that you’re not using while camping and hiking anymore, you shouldn’t throw it away; there are others that may need it. Let’s see what uses a Mylar has in an emergency situation or around the house:
- The first use is in an emergency situation, when you’re trying to stay warm until the rescue teams reach your location. Also, it’s very useful if you go camping during winter: place it inside your sleeping bag and you’ll be properly insulated from the cold;
- The blanket is waterproof and it can provide protection in case your tent starts to soak from the humidity;
- It can be used as a heat reflector so all the heat from the fire will be redirected towards you;
- It is highly visible so you can use it when signaling for help. You can make different shapes with the blanket or you can cut stripes and leave them on the ground to form a trail or mark your way when you get lost in the woods;
- Returning to its waterproof properties, you can create a shelter to protect you against the rain. Tie your blanket with a rope to some solid branches or a tree and you will not get wet;
- You can use it to obtain water during winter. If you place it in the sun and put some snow on it, you will get fresh potable water;
- You make a fishing rod out of a piece of Mylar and a stick (fish are attracted to shiny colors);
- The blanket is quite resistant so you can put it together to form a cord in case you need one. However it may be not strong enough to hold the weight of a human body so it is advisable not to repel down a rock.
- In some emergency cases you might need a tourniquet. You can create one by cutting a few strings out of the emergency blanket. It is an improvisation but it will hold until you receive professional help.
- Due to the fact that it reflects light it can be used to start a fire, by directing the rays to the tinder (using it as a magnifying glass). Still, it’s always recommended to have another fire source with you in case this doesn’t work or it takes too long;
- Use it as a water proofing material for your boots and backpack. Line the interior of tour shoes and backpack with pieces cut from the blanket. This way, not matter how much rain it pours down, you’ll be dry and thing in your backpack will live to see another day;
- In case you break an arm, you can use the blanket to support it until you manage to reach a doctor;
- The blanket is resistant so you can use it to carry water or anything else you need;
- In the summer, when you want to keep your food or drinks cold while camping, you can pack everything in the blanket, tie it well and place it in cold water (a creek or a river). Make sure you secure it so it doesn’t float away;
- If you are caught in a wild forest fire that threatens to reach you, find a creek, submerge your body completely under water and create an air pocket with your emergency blanket. Breathe like this until the fire passes over;
- You can fill it with heavy materials to create an anchor;
- It prevents heat from going out so if you need to keep the house or the chalet warm, simply cut large pieces from the emergency blanket and isolate the windows and doors with them and some duct tape;
- It also can be helpful in the garden: during hot summers the vegetables may fade if they don’t have enough water. Cover them with the foil and it will not let the moisture evaporate.
- The blanket can keep the birds away from your garden as they are scared of the light reflections. This way the tiny beings won’t nibble your fruits anymore.
As you can see, preserving life in an emergency situation may be the first use for an emergency blanket, but it’s not the only use.
