Very quick extinguisher colour / date question

Post by witsd » Mon Apr 29, 2019 11:15 am

When was the last time that it would have been acceptable to be using a blue dry powder extinguisher?

Monday morning is not helping me add this one up, and the internet isn't being helpful! :roll:

Great question that I couldn’t help look at according to Surrey Fire website, they ceased in 1997.
You should be very proud to have found a museum piece😎

Two museum pieces.

Still not as good as the bright green halon extinguisher I found in a shed a few years ago, last checked in 1987... :roll:

Blimey, that is a relic and a dangerous one too

I was working on a project on a former US airbase in east Anglia and found some purple something US extinguishers - complete with a separate co2 charging cylinder. The base of the larger unit was rotten as the last test date was in the early 70s!

I was frightened to touch it to be honest as it would have been blown to rusty pieces if activated

More recently, I have started a policy of removing extinguishers from locked rooms- such as plant rooms etc - as they keep being missed by service engineers. I came across a co2 last tested in 1986 back in January, so had to take action

'Purple K' is a Dry Powder extinguisher that is around 80% Potassium Bicarbonate and is actually coloured Violet/Purple to distinguish it from other DP Extinguisher powders.
Common in the USA (and other areas of the world where they have Fire Influence) usually with MACR sites, Airports, Oil refineries, Military Airfields etc. Usually marked as "PKP".

The big Flight Line extinguishers used to be around 140lb of powder with a separate bottle to charge it, CO2 I think that was (is).

I seem to recall one of it's properties was that it was compatible with Form, the PKP putting the flames out and the Foam laying on top to keep it out.
Other DP extinguisher materials are not compatible with foam.

Given that there is no legal requirement for colour marking of extinguishers, only the BS, so long as it has been correctly serviced and inspected, then there is no requirement for it to now be Red.

I saw this Foam one in 2014, all the servicing dates were still current, from a reputable local firm.

I have this one in my shed. After many months and several emails of badgering the Council, I finally found how I can legally dispose of it. Having got a Waste Transfer Certificate from the Council, which is only valid for something like 7 or 8 days, I have to make a 100+ mile round trip to completely the other end of the County, in order to take it to the one Contractor who is their licenced recycler for it. I'll make a greater environmental damage contribution driving around with it than if it were to leak away..... So when I'm actually going past this remote location in the middle of nowhere, I'll ask for a Transfer chit!
It hasn't happened for 2 years, perhaps this will be the year....

I thought that might be the case.

But as for the test dates, well:

Supplied in 2007? Obviously years out of date, but it seemed doubly odd to supply two blue extinguishers well after them being pulled from general use.

So very clearly out of date.
The company who supplied are still in operation. I just looked them up ;)
It may well be that in a bygone time, before we became a throwaway society for extinguishers, they did actually do a re-lifing maintenance on them.
That foam one I posted a photo of was only 4 years ago and I can't remember the full details, but I know all the dates were correct at the time.
