THE GREAT INVENTION OF FIRE BLANKETS
A FIRE BLANKET is a safety device designed to extinguish small incipient (starting) fires. It consists of a sheet of fire-retardant material which is placed over a fire in order to smother it.
Small fire blankets, such as for use in kitchens and around the home, are usually made of fiberglass and sometimes Kevlar, 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.
Some older fire blankets were made of woven asbestos fiber and are not NFPA rated. This can pose a hazard during the decommissioning of old equipment.
