What kind of fire extinguisher should be used on flammable metals?

For fighting fires involving flammable metals, a Class D fire extinguisher is the correct choice. This type of extinguisher is specifically designed to combat fires caused by combustible metals such as magnesium, titanium, and sodium. These metals burn at extremely high temperatures and can react unpredictably to water and other typical extinguishing agents.

Class D fire extinguishers often contain dry powder agents that can absorb heat and smother the flames without causing a violent reaction, which can occur when water or certain other chemicals come into contact with burning metals. Using the correct type of extinguisher is crucial in effectively and safely addressing such hazardous situations.

The other fire extinguisher classes are not appropriate for flammable metal fires:

• Class K is for fires involving cooking oils and fats.

• Class B is used for flammable liquids like gasoline, oils, and solvents.

• Class C is designated for electrical fires.

Since each type of extinguisher is designed for specific fire hazards, using the correct extinguisher ensures effective fire suppression while minimizing risks.
