What does Class E refer to in fire classification?

Class E in fire classification refers specifically to fires that involve electrical apparatus. This category is important because electrical fires can behave differently from other types of fires due to the presence of live electrical currents. When dealing with such fires, the use of water or typical extinguishing agents can be hazardous, as they may conduct electricity and pose a greater risk of electrical shock or worsen the fire situation.

Understanding that Class E fires require specialized handling is crucial for safety. Specifically designed extinguishing agents, such as carbon dioxide or dry powder extinguishers, are often used to safely put out electrical fires without the risk associated with conductive materials. This knowledge is vital for both training and practical response in emergency situations involving electrical equipment.
