what element of the fire triangle does a fire blanket remove?

A fire blanket removes the oxygen element of the fire triangle by smothering the flames and cutting off air.

Quick Scoop: How a Fire Blanket Works

When you place a fire blanket over a small fire (like a pan fire):

• It creates a seal over the flames.
• This seal blocks fresh air from reaching the fire.
• Without enough oxygen, the fire can no longer sustain combustion and goes out.

In the classic fire triangle:

• Heat
• Fuel
• Oxygen

…the part that a fire blanket targets is oxygen by suffocating the fire rather than cooling it (heat) or removing the fuel.
