What can cause a Class B fire?

A Class B fire is specifically fueled by flammable liquids and gases, which includes substances like gasoline, oil, grease, and other combustible liquids. These materials can rapidly ignite and spread, presenting unique challenges in firefighting. Fire extinguishers designed for Class B fires typically use foam, carbon dioxide, or dry chemical agents to smother the flames and effectively extinguish the fire.

The other materials listed, such as electrical wiring, cooking materials, and paper products, do not classify as Class B fire fuels. Electrical wiring can lead to electrical fires, cooking materials relate more to Class K fires typically involved with cooking oils and fats, and paper products are associated with Class A fires that involve ordinary combustibles. Understanding the specific classes of fires helps in selecting the appropriate extinguishing method and enhances overall fire safety awareness.
