Wholesale PricingThe Amerex B402T is a professional-grade, 5 lb ABC dry chemical fire extinguisher that represents the perfect balance between high-capacity suppression and lightweight maneuverability. Rated 3-A:40-B:C, this unit provides triple the Class A extinguishing power of a standard 2.5 lb unit while remaining light enough for any staff member to operate effectively under stress. Whether you need protection for a hospital corridor, a retail stockroom, or a fleet service truck, the B402T is engineered to tackle the most common industrial and commercial fire threats.
Built with a high-strength drawn-steel cylinder and an all-metal valve assembly, the B402T avoids the common failure points of plastic-head consumer models. It is a fully rechargeable, sustainable safety asset. The "T" in B402T signifies that this model includes a UL-Listed vehicle bracket, keeping the unit secured during high-vibration transport in work vans and service trucks.
The Science of Multi-Purpose Suppression
1. 3-A Thermal Insulation (Class A)
On Class A fires involving wood, trash, and fabric, the chemical agent undergoes sintering at roughly 350°F. The powder melts and forms a resilient, oxygen-excluding crust over the fuel. This coating is the key to preventing deep-seated re-ignition — a common danger in office fires involving dense paper.
2. 40-B Vapor Suppression (Class B)
For Class B liquid fires, the B402T provides enough agent to suppress 40 square feet of a deep-layer flammable liquid fire. The fluidized powder acts as a chemical catalyst, interrupting the free-radical chain reaction within the flame zone.
3. Class C Dielectric Safety
The agent is siliconized to ensure it remains moisture-resistant and non-conductive. This allows an operator to safely engage fires in breaker panels or server racks without the risk of electrical shock.
Why the B402T is the Right Choice
- Extended Discharge Time: The B402T provides approximately 14 seconds of discharge time, allowing the operator to refine their sweep technique at the base of the fire.
- Increased Discharge Range: With a high-velocity nozzle, the B402T can project agent up to 18 feet — essential for maintaining safe distance from intense heat.
- Vehicle and Marine Readiness: The included UL-Listed vehicle bracket keeps the unit secured during high-vibration transport in work vans and service trucks.
The 5 lb capacity is the primary specified choice for high-density hazard zones:
- Hospitals and Healthcare: The ideal weight for nurses and staff to handle while providing significant 3-A protection.
- Restaurants: Providing supplemental protection for dining areas where electrical (Class C) hazards are present.
- Fleet and Utility Vehicles: The DOT-compliant choice for heavy-duty trucks requiring higher knockdown power.
- Retail and Small Business: Protecting stockrooms from ordinary combustibles.

To maintain NFPA 10 compliance, the B402T must follow a standardized maintenance cycle:
- Monthly Visual Inspection: Verify the pressure gauge is in the green zone and the safety pin is secured.
- Annual Service: A technician must conduct an external examination and verify the chemical's fluidity.
- 6-Year Internal Maintenance: Every six years, the unit requires a full internal inspection and agent replacement.
- 12-Year Hydrostatic Test: At the twelve-year mark, the steel cylinder undergoes a hydrostatic pressure test to verify its structural integrity.
What is the difference between a 3-A and 2-A rating?
A 3-A rating means this 5 lb unit has 50% more extinguishing power on wood and paper fires than a standard 2-A rated unit. It allows you to tackle larger fires with a smaller, more manageable unit.
Can I use this on my home computer?
While safe for Class C electrical fires, the dry chemical powder is mildly corrosive and leaves a residue. For data centers and sensitive electronics, a CO2 or clean agent extinguisher is recommended to avoid residue damage.
Where can I find wholesale fire equipment?
For outfitting large facilities, look for wholesale fire equipment distributors who specialize in Amerex products. They can provide the volume pricing needed for a complete facility safety program.
