Emergency Space Blanket: How to Use for Survival

An emergency space blanket, also known as a thermal blanket or survival blanket, is a lightweight, compact piece of equipment designed to retain body heat in emergency situations. Often made from a thin, metallic material like Mylar, these blankets are incredibly effective at preventing hypothermia, a potentially life-threatening condition where your body loses heat faster than it can produce it. They are a staple in first-aid kits, bug-out bags, and are frequently carried by hikers, campers, and anyone who spends time outdoors. But simply *having* a space blanket isn’t enough; knowing how to use it correctly is crucial to maximizing its benefits.

This guide will cover everything you need to know about emergency space blankets, from how they work and what they’re made of, to the proper techniques for using them to stay warm and safe in a survival scenario. We’ll also discuss common mistakes to avoid and how to choose the right blanket for your needs.

How Do Emergency Space Blankets Work?

The effectiveness of a space blanket lies in its reflective properties. The Mylar material is designed to reflect up to 90% of the body’s radiant heat back towards the person wrapped inside. This is different from traditional blankets, which primarily trap air to provide insulation. Space blankets don’t necessarily *warm* you up; they prevent you from losing the heat you already have. This makes them particularly valuable in cold environments or when you’re wet, as moisture significantly accelerates heat loss.

It’s important to understand that space blankets are not a substitute for proper clothing and shelter. They are a temporary solution to help stabilize your body temperature until you can find or create a more sustainable source of warmth. They are most effective when used in conjunction with other survival strategies.

Materials and Types of Space Blankets

Most emergency space blankets are made from a thin sheet of polyethylene terephthalate (PET) coated with a metallic layer, typically aluminum. This combination provides the reflective properties and durability needed for survival situations. However, there are variations in quality and features:

• Standard Mylar Blankets: These are the most common and affordable type. They are lightweight and compact but can be easily torn.
• Reinforced Blankets: These blankets have a layer of more durable material, like nylon, laminated to the Mylar, making them more resistant to tearing and punctures.
• Bivy Sacks: These are essentially space blankets shaped like sleeping bags, offering more complete coverage and protection from the elements.
• Double-Sided Blankets: Some blankets feature a silver side for reflecting heat and a gold side for signaling rescuers.

Proper Techniques for Using a Space Blanket

Using a space blanket effectively requires more than just wrapping it around yourself. Here’s a step-by-step guide:

1. Minimize Exposure: Before opening the blanket, find a sheltered location if possible, even if it’s just behind a rock or tree. Reducing wind exposure will significantly improve the blanket’s effectiveness.
2. Wrap Tightly: The key to retaining heat is to minimize air space between your body and the blanket. Wrap the blanket tightly around your entire body, including your head and neck.
3. Reflective Side In: This is a common mistake. The reflective side of the blanket should face *towards* your body to reflect your radiant heat back to you.
4. Seal the Edges: Use the corners of the blanket to create a sealed cocoon around yourself. This will further reduce heat loss.
5. Protect Your Head: A significant amount of heat is lost through the head. Ensure your head and neck are well-covered.
6. Stay Dry: If possible, avoid getting the blanket wet. Wet Mylar loses its reflective properties and can even conduct heat away from your body.

Understanding how to build a simple shelter can greatly enhance the effectiveness of your space blanket. Combining the two provides a more robust defense against the elements. You might consider learning about shelter building techniques before venturing into the wilderness.

Common Mistakes to Avoid

• Incorrect Side Facing Out: As mentioned earlier, the reflective side must face inwards.
• Loose Wrapping: A loose blanket allows too much air circulation, reducing its effectiveness.
• Tears and Punctures: Even small tears can significantly reduce the blanket’s ability to retain heat. Handle with care.
• Overconfidence: A space blanket is a temporary solution. Don’t rely on it as your sole source of warmth.
• Ignoring Other Needs: Staying warm is crucial, but don’t forget about hydration and signaling for help.

Choosing the Right Space Blanket

When selecting a space blanket, consider the following factors:

• Durability: Reinforced blankets are a good investment if you anticipate rough conditions.
• Size: Choose a blanket that’s large enough to completely cover your body.
• Features: Consider features like double-sided reflectivity or bivy sack designs.
• Weight and Packability: Emergency gear should be lightweight and compact.

Regularly check your space blanket for tears or damage. Replace it if it’s compromised. Knowing basic first aid principles can also help you assess and address hypothermia symptoms.

Conclusion

An emergency space blanket is a valuable tool for survival, but its effectiveness depends on knowing how to use it correctly. By understanding the principles behind its operation, practicing proper techniques, and avoiding common mistakes, you can significantly increase your chances of staying warm and safe in an emergency situation. Remember, preparation is key. Include a space blanket in your emergency kit and familiarize yourself with these guidelines before you need them. It’s a small investment that could potentially save your life.

Frequently Asked Questions

Can I reuse a space blanket?

Yes, a space blanket can be reused if it’s not torn or damaged. However, repeated folding and unfolding can weaken the material. Inspect it carefully before each use. If it’s compromised, it’s best to replace it.

What should I do if my space blanket gets wet?

A wet space blanket loses much of its effectiveness. Try to dry it as much as possible using body heat or a fire (carefully!). If it remains wet, it’s better to use it as a windbreak rather than relying on its reflective properties.

Are space blankets effective in hot weather?

While primarily designed for cold weather, space blankets can also be used in hot weather to reflect sunlight and prevent overheating. However, be careful not to trap too much heat, as this can lead to dehydration.

How long can a space blanket keep me warm?

The duration of warmth depends on various factors, including the ambient temperature, wind conditions, and your physical condition. A space blanket can provide several hours of crucial warmth, but it’s not a long-term solution.

What is the difference between a space blanket and an emergency bivy sack?

A space blanket is a flat sheet of reflective material, while an emergency bivy sack is shaped like a sleeping bag, offering more complete coverage and protection from the elements. Bivy sacks are generally more effective but also bulkier and more expensive.
