Fireboy Halon Fire Extinguisher (April 1989)

We installed this extinguisher and it is still in the engine compartment. It has a temperature sensitive valve that will operate to discharge the unit in case of a fire. Halon was later banned and these devices are no longer available. I was concerned if would still work. So we contacted Fireboy. They advised us t to have the unit weighed and check the weight against the data on the unit label. If the weight is correct, the unit is still functional. In December 2014, we had the unit weighed on an official scale and it still weighs the correct amount. It is still installed in the engine compartment. Fireboy also provided documentation of the unit suitability for service.
