Certain metals, magnesium, potassium, sodium titanium, alkyllithiums, Grignards, and diethylzinc are extremely combustible and must be used with caution and appropriate safety measures. These chemicals react violently with water, air, and other chemicals and cause class D fires, which burn at high temperatures. A Class D fire extinguisher is needed to combat these specific types of fires.
D extinguishers contain a sodium chloride or copper powder. When discharged on a fire, the heat causes the powder to cake and form a crust which excludes air and dissipates the heat.
The Amerex “soft flow” extension applicator is particularly suited for fighting Class D fires. It keeps the operator’s hands away from the extreme heat and prevents inhalation of toxic fumes caused by burning material. The easily controlled, even discharge provides a non-dispursing application of the agent. The applicator may be quickly detached to provide a straight stream of chemical where greater range, a narrow discharge pattern or a lobbing effect is required.
Class BFlammable or combustible liquids such as gasoline, kerosene, paint, paint thinners and propane.
Energized electrical equipment, such as appliances, switches, panel boxes and power tools.
