Powder Extinguishers

[mike ashurst]

I've just bought a 2 Ltr AFFF extinguisher from Halfords (£39.99 special order)

 

But my partner was going to buy a powder ext inguisher for her MGA.

 

I thought that there were cases some time ago of powder extinguishers not working in cars/caravans due to the powder "packing".

 

Any know if that is still the case, and if so, why do they still advertise them for this purpose?

 

Cheers

Powder extinguishers need to be agitated before activation, no matter how long they've been sat. I know that in the heat of the moment (sorry!) the last thing you want to do is stand around shaking the extinguisher, but if you don't, it won't put the fire out...........

Never was a problem when I was a fireman, but does she really want to spoil her old and beloved car by the powderquestion.gif As it is alcaline, it'll make everything rust, especially as it is also hygroscopic. If the main issue is to put out fire, powder is fine, if it is to save the car, find an alternative! I don't know what you are allowed to use in the UK, personally I'd prefer CO2.

I'm reliably informed that AFFF is a good bet and to avoid powder ones for automotive use.

 

As for CO2, well I've never seen one advertised as for use in a car (I know, I know, the fire wouldn't be able to tell!).
