Class B Fires involve what?

Class B fires specifically involve flammable liquids, gases, and greases. These types of fires are characterized by their ability to spread rapidly due to the presence of volatile substances that are commonly found in various industrial and household settings, such as gasoline, oil, paint, solvents, and propane.

Understanding that Class B fires require specific firefighting techniques is essential, as water is ineffective and can actually spread the fire. Instead, specialized extinguishing agents such as foam, carbon dioxide, or dry chemical extinguishers designed for Class B fires are utilized to smother the flames and prevent re-ignition.

This categorization of fire types is crucial for safety protocols and emergency response strategies, particularly for those involved in pipeline operations, where flammable materials may be present. Recognizing the characteristics and appropriate response to Class B fires helps ensure effective management of risk in environments that handle such substances.
