Fire blankets are crucial safety devices designed to extinguish small fires or protect individuals from flames in emergency situations. Typically made from fire-resistant materials like fiberglass or wool, these blankets are stored in easily accessible locations for quick deployment. When thrown over a small fire, they smother it by cutting off the oxygen supply, effectively putting out the flames. 

Fire blankets are especially valuable in kitchen fires caused by cooking accidents, where they can be used to cover burning pots or pans. Their versatility, ease of use, and effectiveness make fire blankets an essential component of fire safety equipment in homes, workplaces, laboratories, and various public spaces. Regular maintenance and proper training on how to use them are vital to ensure their efficacy during critical situations.
