2. Safety Information
Always prioritize personal safety. Only attempt to extinguish a fire if you believe it is still in its inception stage and you have a clear path of egress. If the fire is past its inception stage or you are unsure, immediately evacuate the area and call emergency services (911).
Fire Classes

- Class A: Ordinary combustibles like wood, paper, cloth, and plastic.
- Class B: Flammable liquids such as gasoline, oil, grease, and alcohol.
- Class C: Energized electrical equipment.

3. Setup and Installation
The Amerex B456 fire extinguisher comes with a bracket for easy mounting. Choose a visible and easily accessible location, away from potential fire hazards and heat sources. Ensure the extinguisher is mounted securely to prevent accidental dislodgement.


Mounting Brackets
Various types of mounting brackets are available to suit different installation needs. The included bracket is designed for standard wall mounting. Ensure the bracket is installed using appropriate hardware for the wall material.

4. Operation
To effectively use the Amerex B456 fire extinguisher, follow the PASS method:
The PASS Method
- P - Pull: Pull the pin. This breaks the tamper seal.
- A - Aim: Aim the nozzle or hose at the base of the fire.
- S - Squeeze: Squeeze the operating lever to discharge the extinguishing agent.
- S - Sweep: Sweep the nozzle from side to side at the base of the fire until it is extinguished.
Stand back 8-10 feet from the fire when beginning to discharge. Be prepared for discharge recoil by holding the extinguisher and hose firmly. Continue to discharge even if the fire appears out to prevent re-ignition. Once the fire is completely extinguished, evacuate the area safely and call 911 if assistance or medical attention is needed.
5. Maintenance and Inspection
Regular maintenance and inspection are crucial to ensure your fire extinguisher is ready for use in an emergency.
Monthly Visual Inspection
- Check that the extinguisher is in its designated place and is easily accessible.
- Verify that the pressure gauge needle is in the green operating range.
- Ensure the pin is intact and the tamper seal is not broken.
- Inspect for any signs of physical damage, corrosion, leakage, or clogged nozzle.
- Clean any dirt or debris from the extinguisher.
Annual Professional Inspection and Recharging
The Amerex B456 fire extinguisher requires an annual professional inspection. This product comes with a 12-month annual inspection tag. After any use, even partial discharge, the extinguisher must be professionally recharged by an authorized Amerex distributor to ensure it is fully operational for future use.
6. Troubleshooting
If you encounter issues with your fire extinguisher, consider the following:
- No Discharge: Ensure the safety pin has been fully removed and the operating lever is squeezed completely. If the gauge shows no pressure, the unit needs recharging.
- Fire Re-ignition: If the fire re-ignites after initial suppression, continue to discharge the extinguisher if it is safe to do so and you have sufficient agent remaining. If not, evacuate and call emergency services.
- Damaged Unit: Do not attempt to use a damaged extinguisher. Replace or have it professionally inspected and repaired.
