Man Using A Fire Blanket

Did you know that approximately one of four residential fires start in the kitchen?

This fact alone should indicate how important it is to own and know how to use your fire blanket.

What Is A Fire Blanket?

fire blanket is a sheet made from a malleable material such as wool or woven fibreglass.

All fire blankets are treated with flame-resistant chemicals and can resist temperatures of up to 500 degrees Celsius.

Fire blankets are ok to be used on small Class A and B fires as well as Class F cooking fires.

How To Use A Fire Blanket?

It’s crucial to remember that a fire blanket use is only useful in cases of minor fire.

  • Turn off all electricity/gas supply that can add to the fire — for example, the gas on the stove.
  • Completely cover the fire with the fire blanket to ensure that no oxygen is reaching the fire. A Fire blanket works by blocking the oxygen from the fire, which then disrupts the chemical process needed for a fire.
  • While using the fire blanket, be sure to wrap the top edges of the blanket around your hands to prevent any burns. Also, be careful not to let your clothing catch fire.
  • Gently place the blanket down instead of trying to throw it over the fire; a sudden rush of air could spread the flames.
  • Leave the blanket to sit for around half an hour and do not touch the fire blanket until it has had enough time to cool down.
  • Evacuate the area and call 111 to get the fire brigade immediately if you’re unable to extinguish the fire with the blanket.


Fire blankets are not intended to be reused, so make sure you dispose and replace your fire blanket once it has been used.

It is also possible to use Fire blankets on clothing. If the clothing you are wearing catches fire, you can wrap the blanket around yourself to smother the flames and extinguish the fire.
