Metal fires involving magnesium, sodium, potassium and sodium-potassium alloys, zirconium, uranium, titanium, and powdered aluminium.

MODEL 571 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. Copper powder has been found to be superior to all other known fire extinguishing agents for lithium.

These EXTINGUISHERS are pressurised using ARGON. Argon is an inert gas that will not react with combustible metals. Nitrogen pressurising gas could cause a reaction when used on certain combustible metal fires. Air pressurising SHOULD NEVER be used, as even the slightest amount of moisture will cause a violent reaction will Class D Materials.
