I can say with some certainty the fire extinguishers do actually work having used one to put out a slight mishap involving me and a welding kit (not on the car btw) Then again a 1kg unit will put out about 2 ltrs of petrol easly as long as you can see the seat of the fire and actually know how to use the extinguisher propperly (IE drive the fire back with a rapid sweeping motion to the back corner) however once out there is still a chance of reignition unlike with AFFF but that doesnt have the instant knock down power of dry powder is a real pain to use properly and you need more of it...
the same ANAF extinguishers are been banged out by the local caravan dealership for £19.99
ISOCOMP ABC 40 Potassium Bicarbonate does have a slight laxative effect then again having put a rather large fire out at work involving an oil drum sized pitch kettle with 2 X 9kg powder units and 9 ltrs of foam i didnt have any undue lavvy moments afterwards
