Amerex ABC Fire Extinguisher

When it comes to aircraft cabin fires, ABC fire extinguishers—while effective for general use—are not recommended for onboard deployment due to their corrosive dry chemical agent. These extinguishers use monoammonium phosphate, which can severely damage avionics, aluminum structures, and electrical systems if discharged inside an aircraft cabin2.

For aviation use, especially in confined cabin spaces, the FAA and industry experts recommend Halon 1211 or Halotron extinguishers. These are classified as “clean agents,” meaning they suppress fires without leaving residue or causing corrosion—critical for preserving aircraft integrity and ensuring post-incident airworthiness2.

That said, ABC extinguishers may still be appropriate for hangars, ground vehicles, or ramp operations, where their broad-spectrum fire suppression capabilities (Class A, B, and C) are valuable and the risk of internal aircraft damage is not a concern.

Would you like help drafting a product description for a Halon extinguisher tailored to FAA Part 135 operators or luxury charter interiors? I can also help compare models based on weight, discharge time, and mounting options.
