Amerex B456 10 lb ABC Dry Chemical Fire Extinguisher

Amerex B456 is a 10 lb ABC (multi-purpose) dry chemical fire extinguisher for Class A, Class B, and Class C fires. It uses a specially fluidized and siliconized mono ammonium phosphate dry chemical that insulates Class A fires by melting at approximately 350°F and coating the surface, smothers and breaks the chain reaction of Class B fires, and will not conduct electricity back to the operator.

Official Amerex model B456, item number 14967. Stored-pressure design with an anodized aluminum valve and a hose and nozzle. A wall bracket is included (official catalog: 801 wall).

How to use

Persons expected to use this extinguisher should be trained. Follow the extinguisher nameplate and the official owner's manual. Discharge time and effective range vary by model; for the B456 the manufacturer lists a 15–21 ft initial range and a 22-second discharge time.

1. Remove the extinguisher from the wall hanger or bracket.
2. Hold the extinguisher upright, twist and pull the ring (safety) pin, snapping the plastic lockwire seal.
3. Starting back a minimum of 8 feet from the fire, grasp the nozzle and aim at the base of the fire nearest you.
4. Keeping the extinguisher upright, squeeze the lever to discharge and sweep the chemical agent stream from side to side. Work the fire away from you while being alert for flashbacks. Move closer as the fire is extinguished, but not so close as to scatter or splash the burning material.
5. When the fire is out, stand by and watch for possible re-ignition.
6. Evacuate and ventilate the area immediately after extinguishing the fire. The fumes and smoke from any fire may be hazardous and can be deadly.
