Fiberglass fire blanket, a simple and practical fire retardant material, is made of silicon or graphite coated fiberglass yarns. It is designed for extinguishing incipient (starting) fires, such as small kitchen fire, welding spatters and hospital purpose. In emergency circumstances, it can shield yourself to escape from a burning building. It can be placed over a fire in order to smother it, thus may be more helpful for someone who is inexperienced with fire extinguishers.
