One type of fire that requires special attention is the Class D fire, which involves burning metals such as lithium, magnesium, steel, and aluminum. Unlike other types of fires, Class D fires require specific types of extinguishing agents to put them out, as water can actually make them worse.
13 wrz 2023 · Class D fires involve combustible metals as the fuel for the fire. The US, Europe, and Australia consider combustible metals as ”Class D.” Combustible metals usually have a very high flash point because you must expose vast amounts of heat to the metal before it burns.
any type of Class D fire, the extinguishing agent must suppress the fire without reacting physically or chemically with the combustible materials. The more familiar dry powder extinguishing agents for controlling combustible metal fires are sodium chloride (salt), copper (US Navy developed for lithium fires) and graphite. It should be
7 paź 2024 · Class D fires involve combustible metals that ignite and burn when exposed to air or water, requiring a Class D fire extinguisher. Unlike conventional fires involving organic materials, flammable liquids, or gases, Class D fires are types of fires fueled by combustible metals such as magnesium, titanium, sodium, zirconium, lithium, and potassium.
Class D fires are dangerous and can spread quickly with surprising intensity. Be prepared and informed on the proper ways to combat the flames and avoid situations that can spark such a fire.
25 paź 2023 · Understanding Class D Fires. Class D fires are unique and can be extremely hazardous due to the involvement of combustible metals. These metals include magnesium, titanium, aluminium, sodium, and potassium, among others.
