Amerex portable fire extinguisher with sodium chloride, 30 lbs, type D (sodium, potassium or magnesium fires), with wall hook

30 lb class D sodium-chloride extinguisher, Amerex

The 30 lb Amerex sodium-chloride portable extinguisher is designed for class D fires, namely combustible-metal fires such as sodium, potassium and magnesium. Rugged and FM approved, it is ideal for laboratories, metal plants and workshops handling these materials. It comes with a wall hook.

The extinguishing agent is sodium chloride, pressurized with argon. Data shows that zirconium, uranium, titanium and powdered-aluminum fires can also be controlled and extinguished with this extinguisher. The cylinder is steel with a weather-resistant baked polyester enamel finish. This Amerex extinguisher is easy and safe to use, thanks to illustrated instructions and a wand that helps apply the powder effectively; the agent forms a crust over the flames and smothers them.

FAQ about the class D extinguisher

What is a class D fire?

A class D fire is a combustible-metal fire. It fights sodium, potassium and magnesium fires. It requires a specific agent and must never be replaced by an ordinary extinguisher.

How is the applicator wand used?

The wand (soft-flow applicator) allows a gentle, controlled application of the powder, which forms a crust that smothers the fire, while keeping the operator away from the heat.

Which metals does it work on?

Sodium, potassium, magnesium and, per available data, zirconium, uranium, titanium and powdered aluminum. For lithium fires, use the EXD571 model instead.
