Class D Fire Extinguishers

Class D fires are defined by the presence of burning metals. The most common metals involved in these fires are magnesium and titanium, while other metals include sodium, potassium, uranium, lithium, plutonium and calcium. These types of fires most often occur in laboratories, warehouses, factories and anywhere the manufacturing process cuts or drills metals. Class D fire extinguishers use a dry powder agent, which will not react with the burning metals and will smother the fire and reduce its spread.

Common Applications:

  • Laboratories
  • Warehouses
  • Manufacturing facilities
  • Other sites that use burning metals
