Burning metals can be extinguished using which type of extinguisher?

Burning metals, particularly those involved in class D fires such as magnesium, sodium, and potassium, require specific extinguishing agents that can effectively suppress these types of flames. Dry powder extinguishers are designed specifically for combating fires involving combustible metals. These extinguishers contain a specialized dry powder that works by smothering the fire and forming a barrier between the burning metal and the oxygen in the air, effectively preventing re-ignition.

In contrast, other types of extinguishers, such as dry chemical, carbon dioxide, or AFFF (aqueous film-forming foam), may not be suitable for extinguishing metal fires. Dry chemical extinguishers typically contain agents that can effectively put out ordinary combustibles and flammable liquids but are not formulated to handle high-temperature metal fires. Carbon dioxide extinguishers do not create a suitable environment for fighting metal fires since they rely on displacing oxygen, which can be ineffective against burning metals. AFFF extinguishers are primarily designed for flammable liquids and will not work effectively on Class D fires, as they can react negatively with combustible metals.

By utilizing dry powder extinguishers, you ensure that the firefighting effort is appropriate and effective for the unique challenges posed by burning metals, reducing the
