Overview
Pulling the pin and sweeping a dry chemical stream across the base of the flames is how the B500 works, with an ABC agent for ordinary combustibles, flammable liquids and live electrical fires. Amerex builds each unit with a metal valve, a corrosion-resistant steel cylinder and a pressure gauge, and this set comes as a pair.
Refillable construction is the reason to choose these: after use a certified technician recharges and re-pressurizes them instead of you replacing the unit. Discharge time is short, so success depends on reaching the fire early and aiming at its base.
Who it's for
Homes with a kitchen and a garage, small shops, landlords and owners of trucks, RVs or boats can place one unit in each high-risk spot. Buyers after a single throwaway can should look elsewhere.

Performance notes
The agent does the work: a fluidized phosphate powder melts onto burning material, coats and insulates it, smothers liquid fires and does not conduct electricity back to the operator. Range and discharge time decide how close you must stand and how long you have, so aiming at the base of the flames from the start matters. Monthly gauge checks confirm each unit is still pressurized.

Frequently asked questions
Can the Amerex B500 be used on a grease or electrical fire?
Yes for both. The listing covers Class B fires including gasoline, oil and cooking grease, and Class C live electrical fires, and the agent will not conduct electricity back to the operator.
Where should the two Amerex B500 units go?
The description suggests one on every floor, one in the kitchen near an exit rather than directly above the stove, one in the garage or workshop, and one near a fireplace, wood stove or space heater.
How do you maintain an Amerex B500?
Check the pressure gauge monthly and have the unit professionally inspected once a year. After any discharge, a certified technician refills and re-pressurizes it.
Can the Amerex B500 be kept in a car, RV or boat?
Yes. The listing says the metal valve and corrosion-resistant steel cylinder hold up in a hot trunk, a cold garage, a boat cabin or an RV storage bay.
