How Long Does a Fire Blanket Last?

A fire blanket is made of fire-resistant materials designed to put out small fires or save someone on fire. Its lifespan depends on many factors, including the materials and how it's stored. 

So, how long does a fire blanket last? How do you know if it's expired? Let's find out. 

Factors Affecting a Fire Blanket's Lifespan

Here are the factors that impact how long a fire blanket lasts: 

Material Quality 

High-quality materials can withstand more extreme conditions and last longer. On the other hand, lower-quality materials degrade faster.

Plus, most fire blankets are not designed to be reused. However, you can store tougher brands like the Emergency Fire Blanket and Hero Fire Blanket again as long as they're not damaged after use. Just wipe the blanket off, fold it, and put it back in the pouch.

Storage Conditions

How you store your fire blanket also affects its lifespan. Putting it in a dry place away from direct sunlight and moisture helps keep it in good condition. If you want to know more about how to store your fire blanket properly, check out our guide

How to Tell if a Fire Blanket is Expired

Now that you know what factors affect a fire blanket's lifespan, it's time to know how to tell if it's expired. 

1. Check the Manufacturing Date

A fire blanket's manufacturing date and lifespan are usually printed on the pouch. If it is older than the recommended lifespan, it's time to replace it. 

2. Inspect for Physical Damage 

Check your fire blanket for visible damages like holes, tears, frayed edges, burn marks, and rips. They affect the blanket's effectiveness, so replace your fire blanket if you see them. 

3. Check the Blanket's Condition

Over time, the materials of a fire blanket can be brittle, especially if it's regularly exposed to heat or direct sunlight. Noticeable fading or discoloration can also mean that the materials are degrading. If you see any of these signs, consider replacing your fire blanket. 

4. Examine for Moisture or Mold

A fire blanket stored in a damp environment is a breeding ground for moisture or mold, which can affect the blanket's effectiveness. We suggest you throw the fire blanket if there's mold or moisture. 

5. Review Usage History

Has your fire blanket been used to put out a fire? If yes, consider replacing it. The heat and stress from putting out a fire can affect its integrity. 

Thankfully, Prepared Hero's Emergency Fire Blanket and Hero Fire Blanket are tougher than most fire blankets in the market. You can often reuse them because they can withstand higher temperatures. If they're not damaged after use, just wipe them off and fold them back into their pouches.
