Types of Fire Extinguishers DRY POWDER D Combustible Metals • Class “D” fires. • Sodium chloride, copper, or graphite based. Some handle multiple types of metals, others will not. 6 -8 ft. maximum effective range. Low velocity nozzles or discharge wands apply gently to avoid disrupting finely divided burning materials. • • Extinguishes by cooling and smothering. Powder will act as a heat sink, while forming a crust that cuts off oxygen supply.

Apparently Graphite fire extinguisher work better on magnesium fires than lithium, but still do some good depending on the battery chemistry.
