SRI CLASS D FIRE EXTINGUISHER

Magnesium, Potassium, Sodium Titanium, Alkyllithiums, Grignards, and Diethylzinc are extremely combustible
Therefore, people must be caution and follow appropriate safety measures when used
These chemicals react violently with water, air and other chemicals and cause class D fires which burn at high temperatures
Thus, typical fire extinguishers are not sufficient for this type of fire
Class D contains Sodium Chloride or Graphite metal-based powder
When discharge on a fire, the heat causes the powder to cake and form a crust
The crust excludes air and dissipates the heat.
