Which fire extinguisher type would you choose for a fire involving flammable metals?

For a fire involving flammable metals, the appropriate choice is indeed Type D fire extinguishers. These extinguishers are specifically designed to combat fires caused by combustible metals such as magnesium, titanium, and sodium.

Type D extinguishing agents are usually composed of dry powder materials that smother the burning metal and also disrupt the chemical reactions that are sustaining the combustion. This is crucial because traditional extinguishing agents like water or foam can react dangerously with burning metals, leading to explosive reactions or the spreading of the fire.

Using a Type D extinguisher ensures that you are employing the right method to handle a specific type of fire that requires specialized intervention, thus allowing for effective and safe extinguishing of flammable metal fires.
