Title: Which fire extinguisher
Post by: DomP on April 16, 2026, 10:47:51 PM
All this tinkering with carbs and fuel has got me thinking I should invest in a fire extinguisher, ive done some research into them but wondered what you all recommend?  Powder seems the go to choice but it would appear its very corrosive, maybe not an issue when the other option is a pile of melted parts, foam is soon to be banned which leaves CO²

It's only certain types of foam extinguisher which are to be phased out. CO2 gas models are very good, but can still leave hot spots as the gas clears. Just remember that fire needs 3 ingredients:- fuel, air, and  heat. It only needs one removal of these to kill a fire.

Dry powder is the most popular for home type use these days and is readily available. It is good for oil and fuel fires, electrical fires and general house fires. Downside is it makes a lot of mess and a lot of cleaning up. But like you say the alternative to not using it is a lot worse.  Dry powder extinguishes should be changed after a number of years as the powder can start to become packed down, particularly with vibration when the extinguisher is carried in a vehicle. 
Good all round general fire extinguisher.

Foam is also good for oil and fuel fires, should not be used on electrical fires and not a good choice for general house type fires. It also makes a horrible mess and is more for industrial type situations.

CO2 is good for electric fires, it will put out oil and fuel if you are really quick and get the fire right at the start but there is risk of reignition as the CO2 disperses. not much use on oil fires once they start to take hold because of the reignition factor. Not sure how CO2 extinguishers fit in with environmental concerns nowadays.

We carried water, foam and CO2 extinguishers on the RN ships, powder wasn’t a big thing back then.

After nearly 40 years working on oil refineries I've used them all on too many occasions, but in the house and garage I have CO2.

Sometimes we like to be different, sometimes we take what can be salvaged!!🤫

Doing a firefighting course in the Merchant Navy in 72 i was taught you can put a fuel fire out with water you have to bounce it of a steel bulkhead to turn it into a "fog"

Engine room fires on small ships is no fun.  Was on a small survey ship once when diesel was being  sprayed over hot engines, the crew managed to cool the engines down  quickly using the deck hose and then ventilate the space.  Came very close to pulling the big red handle in the wheelhouse. I was initially tasked with going up on the monkey island to close the engine room vents just in case it went up. Whole place stunk of diesel for weeks after that despite a gallon of jizer to wash down the engine room

Yes Greta! Well rightly or wrongly? the tree hugging Greta’s of the world decided that Halon was bad for the Ozone layer. Although all contained in pressurised cylinders and unlikely to be detrimental to the environment. I guess maybe the disposal of said Halon during periodic cylinder inspection and pressure testing. Something like 10years, can’t remember. But a massive cost to the industry changing out all fixed ff systems and replacing with co2 as well as all site wide individual extinguishers. Just remember vaguely about a Paris agreement.

I recently went for a 6kg dry powder extinguisher, covers a wide range of fire risk, and 20sec of discharge, also useful if some low life’s here decide to torch my workshop, this is the world I live in theses days, 29.99 for some peace of mind!
