A fire blanket is a safety product used to extinguish small incipient fires. It consists of a sheet of fire retardant material which is placed over a fire in order to smother it .
Small fire blankets, for use in kitchens and around the home, are usually made of fiber glass, and are folded in to a quick-release container for ease of storage.
Larger fire blankets, for use in laboratory and industrial situations, are often made of wool (sometimes treated with a flame retardant fluid). These blankets are usually mounted in vertical quick-release cabinets so that they can be easily pulled out and wrapped round a person whose clothes are on fire.
