The primary use of a fire blanket is to extinguish small, contained fires by cutting off the oxygen supply. A fire needs three elements to burn: heat, fuel, and oxygen. A fire blanket works by smothering the flames and depriving the fire of oxygen, which causes it to die out. This makes fire blankets highly effective for quickly putting out small cooking fires, electrical fires, or fires involving fabrics.ûire blankets are particularly useful in kitchen environments where flammable oils and liquids may catch fire. Fires caused by cooking oils or grease can spread rapidly and become difficult to manage. By simply placing a fire blanket over the fire, the flames are deprived of oxygen, causing the fire to be contained. It is crucial to note that fire blankets are not meant for large-scale fires but are highly effective for small to medium-sized fires, especially in the kitchen.ûFire blankets can also be used as personal protective equipment (PPE) to shield an individual from flames. In the event that a person's clothing catches fire, a fire blanket can be quickly wrapped around them to stop the flames from spreading and causing severe burns. This method is often used in emergency situations to prevent further injury until professional help arrives.ûIn some cases, a fire blanket can be used to protect a person while they attempt to escape from a fire or hazardous environment. It can serve as a temporary shield, protecting the person from smoke, heat, and flames as they move to a safer location.
