Second, a dry chemical extinguisher-the most common type we see in aircraft-uses chemicals that have effects on the occupants and the aircraft that are so pernicious that we recommend against their use in aircraft. Our research and testing has led us to a two-fold conclusion as to what type of extinguisher you should carry in your aircraft: First, effective means an extinguisher that uses a “clean agent,” either Halon or one of the Halon alternatives-if it is possible to extinguish the fire you’re dealing with, they will do it and they won’t hurt you or the aircraft in the process.
While inflight fires are rare, we think that every aircraft should have an effective fire extinguisher in the cabin where the pilot can reach it quickly and easily. It’s no wonder that pilots dealing with an inflight fire have jumped out of their aircraft even though they had no parachute. Uncontrolled combustion in a confined space is ugly enough-adding altitude and speed to the mix can make a fire lethal in short order. Now, there is an approved alternative available for immediate installation on new aircraft and as a retrofit unit for older aircraft originally equipped with halon fire extinguishers.The idea of an inflight fire rightfully scares the bejabbers out of pilots.
Federal Aviation Administration (FAA) says must perform as well or better than halon, with a toxicity rating that is equal or less, with a favourable environmental impact.ĭespite the pressing need for a halon replacement, it took more than 20 years to develop a suitable candidate: Halotron BrX. With the global supply diminishing, the aviation industry has been working hard to find an effective replacement, which the U.S. Under the Montreal Protocol, halon production has been banned since 1994. Halon was a tough act to follow – that is, until it was identified as an ozone depleting substance. It left no harmful residue on sensitive aircraft electronics, fluids, metals, and composites, and was lightweight and effective on different types of fires. Halon offered reliable performance at extreme temperatures, high altitudes, and while subjected to excessive vibration. The 375H673 is suitable for installation on new aircraft or as a retrofit,” explained Alan Templeton.įor decades, halogenated hydrocarbon (halon) was the firefighting agent of choice in aircraft flight decks, passenger cabins, lavatories, and cargo hold. “Many directors of maintenance, design engineers for airlines and OEMs have asked us for a hose style replacement unit, and it is finally here. With an ozone depletion potential near zero and a short seven-day atmospheric lifespan, Halotron BrX is the clear winner in the race to replace halon. Many aircraft are certified with a hose style extinguisher and the 375H673 is a perfect replacement” continued Alan. Other 2-BTP filled extinguishers are only available with a nozzle attachment, so the 375H673 fills the gap.
The flexible hose attachment allows users to aim directly at fires in hard-to-reach places, such as inside overhead bins or under seats. “The new unit weighs less than other Halon alternative extinguishers with hose and is easy to carry. “CASP had the ability to come up with a solution for not only the extinguisher but also design & manufacture a 16G rated bracket that has a compatible hole pattern with the prior model extinguishers B722538 bracket,” said Alan Templeton, President & General Manager of CASP Aerospace. Realizing the pressing need for this product, CASP Aerospace-which has serviced commercial and military aviation fire extinguishers of all types since 1988-worked with Amerex to ensure the 375H673 meets or exceeds the requirements for aviation operations.
#Halon fire extinguisher portable
Estimated reading time 4 minutes, 20 seconds.įor more than 25 years, the aviation industry has been searching for a viable, environmentally friendly alternative to portable Halon 1211 fire extinguishers.ĬASP Aerospace of Montreal has teamed with Alabama-based Amerex to deliver the CASP model 375H673, a drop-in solution that not only meets all regulatory and environmental requirements, but mates with a fully compatible mounting bracket featuring the same mounting hole pattern as the Halon 1211 units (100-9750 & 30H673) it is replacing.īest of all, the clean agent 375H673 portable fire extinguisher is UL certified, in production, and available today.
