Fire Blankets Fire BlanketsA fire blanket is a safety device designed to extinguish small fires. It consists of a sheet of fire retardant material that is placed over the fire to smother it. Fire blankets are usually made from woven fiberglass and work by smothering the fire and cutting off its oxygen supply. They are stored in wall-mounted cases, or pouches, for quick access in a fire emergency. It's important that fire blankets are easy to find and your staff knows where to locate them.Fire blankets are especially useful for putting out small kitchen fires, such as those caused by cooking oil or grease. They should not be used to attempt to extinguish large fires or fires that are spreading quickly. When faced with a small fire emergency, our flame blankets provide a reliable and easy solution.
