Fire extinguishes

DO NOT CUT THE OLD ONE.
E bay it or donate to local museum.

Screw Fix, tool station or contact your local fire extinguisher company.

really is it that unique

I thought would test one of the old ones out today from the garage and it worked! shame it could not be stopped,
I did not know that they had a co2 cylinder in side that propelled the water out! Can they be refilled and a new co2 cylinder fitted or is it not worth it?

I also did know realise the CO2 extinguishers are made from ali either after taking one apart.

Yellow ardvark is your fire extinguisher expert. I'm sure he'll be along soon, after he's finished doing stuf ...........

@123hotchef
Any complete pre 1970 extinguishers I worth a bit of ££££. They are collected for tv shows.


Not all CO2 are alloy, some are steel. Alloy is most common. But be careful when taking them to scrap yards. not all with take them

the co2 one will be turned into a air tank

Melting alloy, with a mix of scrap wood and charcoal.

Many years ago I used to work for a large extinguisher company who also make locks, doing marine fire firgting systems etc. In Staines they had meusem full of old stuff dating back to victorian times, was actually very interesting

@123hotchef
Check the date stamp on the body of the CO2.
If it is over 10 years old. Junk it.

The newer water type have a fancy diffuser nozzle so you get more effective coverage from the same volume of water and a greater capability. CA ones are charged to 10 bar through a standard Schraeder valve, the label colour denotes the usage to comply with BS 476;

Red. Water- Class A, Carbonaceous fires (Paper, wood, cardboard, natural textiles etc).
Cream, Foam- Class B, Carbonaceous and Running liquids/burning fat.
Black, CO2- Class C, Carbonaceous, liquids and flammable gases
Blue, Class D- Powder, Carbonaceous, liquids, gas and metal fires.
Green (was Halon), flammable liquids, now replaced by Black, CO2.

There isn't actually an electrical class as it's something that's involved in a fire so you're not actually trying to put it out, the idea is to isolate it first then use the appropriate extinguisher for the class involved.
Points to note:
Don't ever try to use a CO2 without it's horn, you'll just accelerate the combustion and keep your hands away from it as it freezes in operation.
If you use foam on a liquid start at the nearest point and form a blanket to flow away from you, make sure it settles on the liquid gently so as not to splash and cause injury or further seats of fire.
Powder is hugely messy and will ruin other electrical apparatus in the vicinity, it will also quickly fill a small area and make the atmosphere unbreathable.
CO2 is best used in a minimum of 2 and again is capable of quickly degrading the atmosphere.
If you need to use one make sure that you are at your means of escape so you get out of there quickly if it all starts going wrong.

Good advice !!

I have various size powder ones as that's what I've been told to use when soldering in people's houses, do I really need others? No mention of it in my liability insurance which surprised me

Put it this way they make a hell of a mess so if you do have cause to use it you will be even more unpopular than you would just setting their house on fire. I'd keep a water or co2 as well.

i always was told to never fight a fire thery are for you to ade in your escape if you had an exit just leave

and no if it was just a small fire yes i would put it out but all training i had over the years thats all they would say

 

[The_Yellow_Ardvark]

@Kayos
The powders are a mess to clean up and if you inhale the powder they can clean you out.

I would advise a 3lt foam for soldering work, I guess the pipes are flammable gas free? If working with heat near a flammable gas system have the powders to hand.

I think fire extinguishers have two purposes one to help you get out of a building in the event of a serious fire, and also to stop something small getting out of hand. In the past i used to do a lot of hot works in big factory's fire extinguishers were used daily just as any other tool, water and co2.

Correct.
Even if you use the unit to bash a door down to escape they have don their job.

How true, if you just run from a building there is no point in having any fire extinguishers. H&S gone mad again.

We often have similar on site, someone unknowingly spills something, something flammable such as paper or plastic blows into a work area, or even a steel supplier sends material with a sticky label attached and all of these can start small fires which can be quickly extinguished.
