Do you have a fire extinguisher in your house?

The basic types are:

Water - Class A fires

Foam - Class A & B fires

ABC Powder - Class A, B & C fires

CO2 - Class B and electrical fires

I was thinking of getting a 2KG CO2 fire extinguisher to be kept in the hallway, for tackling electronical fires as I have quite a lot of electrical stuff in the house. I hope that none of it would catch fire but you never know.

Also, for the kitchen you can get special class fire extinguishers that tackle chip pan fires or oils?? why not just a CO2 one?

Anyway... do you have fire extinguisher(s) in your house, if so what type and weight?

600g BC powder. In the hall very close to front door and main phone.

The fire brigade always tell you to only tackle very small fires and make sure you aren't cut off, otherwise get out and stay out.

Tackling an oil based fire with a CO2 extinguisher would be a tad danderous i would have thought.

The only way to beat any fire is to remove one of the elements of the fire triangle, consisting of Heat, Fuel & Oxygen.

To beat an oil based fire normally you would remove the oxygen using a smothering method using a blanket of foam or the chip pan blanket.

CO2 being a gas would probably turn to liquid resulting in a big flashover, im not 100% sure but im fairly sure im corrrect. That is why CO2 is used on electrical fires as it removes the oxygen and to some degree the heat.

Liquid CO2? Thats like - 150oC - by then I would be frozen dead. But in all fairness the nozzle does go icy when you eject some CO2!

Class F fires involve oils with a very high auto ignition point - 350 degree +. Which means they're bloody hot compared to petrol and the like which has a much lower ignition value.

Petrol is therefore relatively easier to put out using Class B extinguishers.

Class F forms a film over the oil, suffocating and cooling.

Also, CO2 can be dangerous in a confined space like a small kitchen - replaces the air in the the room...

slightly off topic but to concur with what Ian said on one of the sites we look after the fire officer wants to see flame detectors working by setting a pan of meths alight to put it out place a sheet of steel over the pan and stand on it, one day this did'nt work correctly and flames were still licking around the bottom of the sheet steel so he told his deputy to let loose with the co2, which prompted a 6ft flame surrounding the fire officer in the middle, we had to leave the building because we were laughing so much :roflmao: 5minutes later fire officer left the buliding jacket still smouldering :eekout:

Does this mean I can justify keeping a few sticks of explosives in the kitchen drawer?

If ever the chip pan catches light I drop in a stick of explosive, which when ignites starves the fire of oxygen?

I know I am being ridiculous, of course I don't have a chip pan, oven chips all the way for me!

Its been a few years now since my fire extinguisher days but I have 6lt foam as general cover, CO2 for the electrics and a fire blanket for kitchen fire.

You could combine Bellmans idea and load a smoke cloak with gas suppressant.

*disclaimer...do not try this at home.

Nothing is foolproof to a sufficiently talented fool.
