Title: Halon
Post by: longjohn on February 23, 2014, 06:23:06 PM
I have found 3 old halon extinguishers in a garden shed whilst clearing out the property of a recently deceased relative, anyone know where I can safely dispose of them??

Some local authorities dump sites used to take them as long as they were from domestic premises or similar, that would be your first port of call.

I can also get specialist disposal firms to take them (not cheap though) although if they are in good condition & an age/model of use to the preservation/museum sector I may be able to sort something at no cost to you (a picture would help to determine this)

If you can send me a pic I may be able to sort something if you are only in the E.Mids.

I used to like halon. Now you have made me all nostalgic, shorty. (Sorry to hear about your relative though. Hope no one too close.)

Thanks Colin, it was good stuff for extinguishing fires wasn't it, apparently an old extinguisher engineer chap I knew used it as deterrent for intruders, kept a halon extinguisher at hand upstairs and always said he would knock em out with halon, claim that he panicked and then he wouldn't get arrested himself for it, there's a marketing opportunity missed!!!!

As a x RAF firefighter, I recall a bit of BCF in an engine fire was always good. Extinguished the fire without damaging the engine I was taught. Unfortunately it damaged the environment.

If people stopped having fires then very little. ;)

The problem wasn't using it for fire fighting it was using it for everything else such as coolants in refrigerators etc.. It was also used extensively in stripping paint off aircraft and cleaning, who could forget the empty CTC extinguishers on military bases because the contents had been used for cleaning the uniforms! The amount of Halon used for firefighting was minimal compared with these other uses.

Incidentally I believe that halons are still used for paint stripping aircraft in the UK (under strictly controlled conditions) and by the US military and some developing countries (who just don't care).

It always irked me that the diktat on banning Halon, particularly BCF, was made without, as far as I am aware, any proper assessment of the halon versus combustion products effect on the environment. Certainly no one from the Department of Environment asked the Fire Research Station about the matter, despite the fact we were part of DoE, and were at the time showing that nastier things were being given off in fires than many people appreciated.

The late Tony Hudson told me that halon was good for clearing out wasps....

Was our approach to halon a knee jerk reaction - would the far slower phase out from general use as seen in the USA have been more appropriate?

I have an earlyish ICI brochure in the archive fire collection extolling the use of halon as the panacea to virtually all risks in all sectors yet know it's as if it had never existed and we seem to survive...

I still like it as an agent though, it had it's place, was always effective when I needed it.

When I first started out on my own, my office was in a new built link between the house and garage. Very often whilst staring at the phone willing it to ring, I would hear the patter of tiny feet above my head. That's when i discovered that Halon was very successful in killing rodents.

Now, on a more serious note. I have today been in a small private airplane with a 0.7kg hand held halon unit installed in 2002. Can anyone point me in the direction of some recommendations/regulations regarding servicing/refilling such units. It has no pressure gauge like many of the old halons. Should it still be tested/recharged at 10 years? Who would do that? Can I buy replacement units? What do any regulations say about extinguishers in private planes?

Any advice appreciated.

John

Halon is still permitted for use on board aircraft, the extinguishers should be serviced (I can't remember if there are specific CAA requirements or BS5306-3 will do)

At 10 years it should be overhauled.

FFE still do these and you can find a local distributor via their site:

Amerex can also supply halon extinguishers.

in light aircraft, extinguishers are signed off annually by a LICENCED aircraft engineer. all they do is weigh them and record the weight on a sticky label with their licence number and signiature. also cast a glance at pressure gauge if unit has one. no notice is taken of the units age, indeed many chipmunks and other ex military stuff still have 1950s graviner brass headed units. a couple of years ago, i was even given one of those pistol type units that one aircraft had been carrying! its a joke, they dont seem to be required to work to current standards.
