How to Use a Fire Blanket to Extinguish Fires Safely and Effectively

A fire blanket is a safety device designed to smother small fires by cutting off oxygen supply. This guide explains when and how to use a blanket to extinguish fires, its advantages over other methods, and proper maintenance tips for optimal performance.

What Is a Fire Blanket?

A fire blanket is a flame-resistant sheet made from materials like fiberglass or wool treated with fire-retardant chemicals. When placed over a fire, it starves the flames of oxygen, effectively putting them out. These blankets are commonly found in kitchens, laboratories, and workshops.

When to Use a Fire Blanket

You should use a blanket to extinguish fires in these situations:

• Small cooking oil fires (class F fires)




• Clothing fires on a person
• Small electrical fires (after power is turned off)
• Fires in confined spaces where extinguishers might spread flames

Never use a fire blanket on large fires, gas fires, or when the flames are taller than you.

Step-by-Step Guide to Using a Fire Blanket

1. Turn off the heat source if possible (especially for cooking fires)
2. Pull the tabs to release the blanket from its container
3. Hold the blanket by the corners with your hands protected behind it
4. Approach the fire slowly and carefully
5. Place the blanket over the flames completely
6. Leave it in place for at least 15 minutes to ensure the fire is out
7. Call emergency services if the fire persists or grows

Advantages of Using a Fire Blanket

Compared to fire extinguishers, a blanket to extinguish fires offers several benefits:

• No messy chemical residue
• Simple operation with minimal training required
• Effective on grease fires where water would be dangerous
• Reusable after proper inspection
• Compact size for easy storage

Maintenance and Care

To ensure your fire blanket works when needed:

• Store in an easily accessible location away from potential fire sources
• Check periodically for damage or expiration dates
• Replace if the blanket shows signs of wear, holes, or contamination
• Have it professionally inspected annually

Safety Precautions

When using a blanket to extinguish fires, remember:

• Never wrap the blanket around your hands
• Stand between the fire and your escape route
• If clothing is on fire, have the person stop, drop, and roll first
• Don't peek under the blanket too soon
• Have a fire extinguisher as backup

Choosing the Right Fire Blanket

Select a blanket that meets safety standards (look for CE or UL marks). Consider size - standard blankets are 1m x 1m, while larger ones (1.5m x 1.5m) handle bigger fires. For professional kitchens, choose blankets rated for high-temperature grease fires.

Common Mistakes to Avoid

People often make these errors when using a blanket to extinguish fires:

• Using it on fires that are too large
• Not covering the fire completely
• Removing the blanket too quickly
• Storing it near the stove where it's hard to reach during a fire
• Forgetting to call emergency services after use

By understanding how to properly use a fire blanket, you can effectively handle small fires before they become emergencies. Always prioritize safety and remember that fire blankets are just one part of a comprehensive fire safety plan.
