What type of extinguisher is recommended for extinguishing burning metals?

Dry powder extinguishers are specifically designed to combat fires involving combustible metals, such as magnesium, sodium, and potassium, which are classified as Class D fires. These extinguishers contain a specialized dry powder agent that works by smothering the burning material and interrupting the chemical reaction of combustion.

Unlike water-based extinguishers, which could react dangerously with certain metals (causing explosive reactions), or foam and CO2 extinguishers, which are not effective on metal fires, dry powder extinguishers provide a safe and effective means of extinguishing these types of blazes. This makes them crucial for environments where combustible metals are present, ensuring the safety and effectiveness of fire response strategies.
