An item of cloth with fire-resistance qualities sewn into blankets specifically designed for workers in labs, workplaces, and other locations where small fires are a possibility is known as a fire blanket. The commonly used material for this cover is either wool or fiberglass to accelerate efficient rescue operations. It defunct flames by canceling the oxygen supply that the fire needs to do the process of combustion. Glass fibers woven into a scheme that holds air pockets together make up fiberglass.
