- Fire extinguishers
I bought a load a while back for the workshop / shed etc, as being at the end of the garden, 50m from the outside tap, it a power tool caught fire etc, I though they’d be quite handy…
Anyway, many years have passed and I’m wondering – how long do they last?
HSE requires work to bin them after 5 years (10 for CO2), but is that just H&S gone mad, or do they magically stop working after 5 years and a day…Posted 3 months ago
That 5 year thing is a “recommendation”.
Although they are not particularity expensive and it’s probably easier for a business to just replace.
Do they have a pressure gauge? If not, how do you know they haven’t leaked slowly over time.
They are in good condition and you can confirm they are still intact, I would keep them for about 10 years or so.
I just bought 2 small 1kg DP ones for £9 in Lidl. Just for the house.Posted 3 months agoNobeerinthefridgeMember
We have literally hundreds on site at work, which are operated from a third party, who’ll replace when the time limit is up.
I’m fairly sure they’ll be inspected/refilled/whatever, rehashed and put back at stations for another 5 years.
Extinguish on, soldier.Posted 3 months ago
Typically local authorities refuse extinguisher in the bin as they’re a hazard to the bin men – but the should accept them at recycling centres – shame yours doesn’t
Water you can just discharge and put it in the scrap metal bin at the recycling centre – its now longer an extinguisher.
Powder – find some sort of fabric bag / receptcle (tie a knot in the end of an old pair of trousers perhaps). Turn the extinguisher upside down and discharge it into the bag. Throw the bag in the bin and the extinguisher is now scrap as well. Keep the powder away from anything electric/electronic – they’re not reccomended for home use any more as the powder finds its way in to electrical goods, attracts moisture and ruins them
Foam can be more problematic as you mustnt let it reach a water course – it needs to go to a foul sewer – but you;’ll easily overwhelm your loo! Any company that offers to service extinguishers will take them away for a small fee though
The FIA one…. stick it on Ebay – its ‘memorabilia”…. and someone else’s problem 🙂Posted 3 months ago
Best to let them off though before attempting this.
don’t listen to him he’s telling fibs. Powder ones should definitely be full and fully pressurised before you take the top off.
Remember to take pics

I have a halon extinguisher in my kitchen! It must be 20+ years old. the gauge still reads OK so I just keep it as it should work if needed. NO idea how i would get rid of it safely
Halon is a very effective fire extinguisher but are now illegal. It’s a really nasty CFC.
You should take it for safe disposal.Posted 3 months ago
I had assumed that once it had been manufactured the damage was done and the safest thing was just to keep it as any disposal would lead to it or some of it ending up in the air
The problem is that eventually the cylinder will begin to leak. I think that the disposal method “destroys” the halon and rids it of it’s ozone damaging properties.Posted 3 months ago
been banned since 2003 ish. I’d be getting rid of that as ethically as I can asap. Before you melt the entire polar ice cap when discharging it.
Still widely used as a fire suppressant in the aviation industry. Pretty sure most Comms rooms in Africa still use Halon 1301 as well (although possibly the won’t be easy to refill anymore).Posted 3 months agomidlifecrashesMember
Were they Kidde extinguishers footflaps? Might be on to some free replacements. Big product recall.Posted 3 months agojamesozSubscriber
I think the Yanks still use Halon. Not sure one little 2kg or whatever will make much difference.
I’ve discharged it in the past. Was testing a Comms room Fire system that had been updated to FM200 (hfc227ea so still not great for the planet).
I disconnected the FM200, hit the Manual release to test the firing pin and woosh, I moved quite quickly out of the Comms room.
Turns out the guys that updated the system had only removed the Cylinders they could see and used the original cables.
Made the old cylinders much lighter to remove.
Pressure vessels over 10 years old should be hydrostatic tested. Realistically scrap in the case of portables and turned into tubeless inflaters.Posted 3 months agoglobaltiMember
A fire extinguisher engineer once told me that the only reason for retiring dry powder extinguishers is that the powder settles over time and becomes a lump, which the gas can’t shift. So if every six months you shake it vigorously while banging it with a rubber mallet you’ve a fair chance that it will work when you need it.
I used to work in a bike factory in Darlaston, which had a modern electrostatic paint spray booth and a conveyor curing oven. The electro-static bit had very sensitive spark detectors because of the high fire risk and if the fire alarm ever sounded, you had 30 seconds to evacuate the building before it would be flooded with CO2 unless somebody hit the override button. So every time the alarm sounded, which was several times a week, the entire workforce of about 100 would explode outwards towards the fire exits like squaddies whose mate has dropped a hand grenade. It was always a welcome little break from assembling crappy bikes for Brown Brothers, Edwardes and Vindec, whoever they were.Posted 3 months agokcalSubscriber
Wasn’t so long ago I had a Halon extinguisher that sat in the car. Not sure how I ended getting it disposed of to be honest! Did it reasonably ethically I think.
I also found a v old NATO standard extinguisher that my my dad had in the garage. Took a while to sort that out but IIRC a friendly RAF neighbour took it off my hands and took in to the base where it wa s- I assumed – disposed of.Posted 3 months ago
