Class D fire extinguishers contain specialised dry powder agents designed to tackle fires involving combustible metals, such as magnesium, sodium, and titanium.
The extinguishing agent is carefully selected according to the type of metal involved, as different metals require different fire control methods.
How Do Class D Fire Extinguishers Work?
Class D extinguishers help control metal fires by applying a suitable specialised powder that covers the burning material, helps isolate it from surrounding conditions, and reduces the spread of the fire.
Using the correct extinguishing agent is essential because an unsuitable agent may react dangerously with certain burning metals.
