Class D Fire Extinguishers

Class D Fire Extinguishers (Metal Fires)

Class D Fire Extinguishers are specially designed to combat fires involving combustible metals such as magnesium, sodium, potassium, lithium, and aluminum powders. Unlike conventional extinguishers, Class D extinguishers use dry powder agents that smother metal fires safely without causing violent reactions. These extinguishers are essential for industrial environments, laboratories, metal processing units, foundries, and manufacturing plants where metal fire risks are high. Engineered for reliability and safety, Class D Fire Extinguishers provide controlled fire suppression while minimizing damage and preventing re-ignition, ensuring compliance with industrial fire safety standards.

Class D Fire Extinguishers are purpose-built safety devices used to extinguish high-temperature metal fires that cannot be controlled with water, foam, or CO₂ extinguishers. They discharge a special dry powder that forms a crust over the burning metal, cutting off oxygen and absorbing heat. These extinguishers are mandatory in industries handling flammable metals. Their rugged construction ensures durability in harsh industrial environments. Class D extinguishers play a vital role in protecting personnel, machinery, and infrastructure from dangerous metal fire incidents.
Class D Fire Extinguishers are widely used in metal fabrication units, aluminum smelting plants, chemical labs, automotive manufacturing, aerospace industries, and battery production facilities. They are ideal for locations where reactive metals are stored or processed. Easy-to-operate discharge mechanisms ensure quick response during emergencies. Proper placement and professional installation are crucial for maximum effectiveness. Regular inspection and maintenance help maintain operational readiness, making these extinguishers a critical part of industrial fire safety planning.
