Class D Fire Extinguisher

MODEL B570 contains a particular blended Sodium Chloride-based dry powder extinguishing agent. The heat from the fire causes it to cake and form a crust, excluding air and dissipating heat from burning metal.

This Class D Fire Extinguisher can extinguish metal fires involving magnesium, sodium, potassium, and sodium-potassium alloys. In addition, data shows that zirconium, uranium, titanium, and powdered aluminum fires can be controlled and extinguished with this unique Fire Extinguisher.

Extinguishing Capacity

• Magnesium Chips: 4 ft.2 and/or 6 lbs. of metal
• Sodium or Potassium Spill: 5 ft.2 and/or 5 lbs. of metal
• Sodium or Potassium Spill Depth Over ”: 3 ft.2 and or 6 lbs. of metal
• Sodium Potassium Alloy Spill: 3 ft.2 and/or 2 lbs. of metal
• Available in 150-lb. Wheeled Extinguisher

MODEL C571 contains a copper extinguishing agent specially developed by the U.S. Navy for fighting lithium and lithium alloy fires. The copper compound smothers the fire and provides an excellent heat sink for dissipating heat. The copper powder is superior to all other known fire extinguishing agents for lithium metal fires and not recommended for lithium-ion battery fires.

Extinguishing Capacity

• 4 ft.2 and/or 5 lbs. of lithium
• Available in 250-lb. Wheeled Extinguisher

* Due to the density of copper, an extra agent is added to achieve 30 lbs. of agent discharge at a 45 angle. The actual extinguishing agent weight–when fully charged is 411/2 lbs.
