What type of fires does Class B refer to?

Class B refers to fires that involve flammable liquids or gases. This classification is crucial for understanding the nature of the materials that are burning and the appropriate methods and extinguishing agents to use when combating such fires.

Flammable liquids can include substances like gasoline, oil, and paint, while flammable gases can consist of propane, acetylene, and natural gas. When dealing with Class B fires, it is important to recognize that typical water-based extinguishing methods are often ineffective and can exacerbate the situation. Instead, extinguishing agents such as foam, carbon dioxide, or dry chemical extinguishers are recommended, as they can effectively smother the flames and prevent re-ignition.

Understanding this classification helps firefighters and individuals involved in emergency response to choose the right approach and equipment, ensuring safety and effective fire control. Recognizing the characteristics of Class B fires is essential in training and prepares personnel to respond promptly and effectively to such incidents.
