Class D Fire Extinguisher
Specialized fire suppression engineered specifically for Class D combustible metal fires. Standard extinguishing agents such as water, foam, CO2, and multi-purpose dry powder can react violently or cause dangerous explosions when applied to burning metals.
Our Class D fire extinguishers utilize specialized metal-suppression powders and low-velocity soft-flow applicators designed to gently smother burning metal shavings, chips, and turnings without scattering burning debris. Sized for industrial workshops, precision engineering facilities, and metallurgical laboratories.

View full detailsHow Class D Suppression Works
Specialized Crusting Agent: Discharges specialized dry powder (such as sodium chloride-based or copper-based compounds) that forms an oxygen-excluding crust over the molten metal, smothering the fire and conducting heat away.
Low-Velocity Soft-Flow Applicator: Equipped with an extended applicator wand and low-velocity discharge nozzle. This allows the operator to stand at a safe distance and gently deposit powder over the fire without dispersing burning metal chips, swarf, or dust into the air (preventing secondary dust explosions).
Common Industrial Applications
Precision Engineering & Machining: CNC milling, grinding, and turning of light metals (magnesium, titanium, aluminum alloys).
Additive Manufacturing & 3D Printing: Facilities handling fine reactive metal powders and sintering waste.
Aerospace & Marine Fabrication: Component manufacturing and structural welding workshops.
Laboratories & Testing Facilities: Chemical research and metallurgical inspection environments handling reactive alkali metals (sodium, potassium, lithium).
