The Amerex B571 30 lbs Copper Fire Extinguisher (Class D) uses a copper extinguishing agent specially developed by the U.S. Navy to fight hard-to-control lithium and lithium alloy fires. Lithium and lithium compounds are pyrophoric, which means that their dust or powder will spontaneously combust in the air at or below a temperature of 130°F. This underscores the importance of having a reliable Class D extinguisher designed to fight lithium fires in areas with huge amounts of lithium shavings or dust such as warehouses, factories, laboratories, or anywhere lithium is cut, drilled, or milled. Please note that the B571 is not recommended for lithium-ion battery fires which are classified as Class B fires.
Superior firefighting performance. The copper powder is found to be superior to all other lithium fire extinguishing agents. It stops the fire by smothering it and acting as a “heat sink” to dissipate heat. It also forms a non-combustible copper-lithium alloy on the surface which cuts off the oxygen supply. The copper fire extinguisher is also the only known lithium firefighting agent that clings to a vertical surface, making it the ideal agent on flowing and three-dimensional fires that tend to spread fast. The 30 lbs B371 Fire Extinguisher is capable of fighting 4 ft.2 and/or 5 lbs. of lithium. Discharge can last for 18 seconds and reach 3-6 feet.
User-friendly design. The Amerex B571 has a unique “soft flow” extension applicator with a built-in long-range nozzle that allows the operator to stand away from the extreme heat and avoid inhalation of toxic fumes caused by the burning metal. This applicator provides an easily controlled, even discharge of the agent. When you need more range, you can quickly remove the applicator to provide a narrower, straight stream of the agent. Like all Amerex extinguishers, the B571 has a large-looped stainless-steel pull pin for easy pulling, as well as QR-coded and bilingual labels.
Rugged, reliable build. Amerex is known for high-quality fire extinguishers that are guaranteed to last long with proper maintenance and service. The Class D fire extinguishers feature a stored pressure design, sturdy drawn-steel cylinders, an all-metal valve construction, a special anti-corrosion yellow paint, and a Class D color-coded paint finish. The Amerex Class D fire extinguishers are safe to use in temperatures ranging from -40°F to 120°F.
Manufactured to the highest industry standards, the Amerex B571 30 lbs Copper Fire Extinguisher (Class D) is tested to ANSI/UL standards, complies with NFPA 10 Standards, is ISO-9001/ISO-14001 certified, and is FM approved. It’s a reliable device that is guaranteed to work when you need it.
