What is the primary purpose of a fire blanket?

The primary purpose of a fire blanket is to extinguish small fires by smothering them. When a fire blanket is placed over a fire, it works by cutting off the oxygen supply to the flames, which is essential for combustion. This method is particularly effective for small, contained fires, such as those that might occur on a person or in a pan. Fire blankets are commonly made of materials that are flame-resistant and can safely blanket an area to suppress burning without contributing to the fire hazard. This application is fundamental in personal safety and fire response, making the fire blanket an essential tool in both home and industrial settings.
