Hi,

I've heard that there is a new type of portable fire extinguisher that can tackle class A fires and also electrical fires.

Has anyone had any experience with these? Are there any limits of the type of electrical fires they cans safely tackle?

Chubb have thier own type of water spray called Hydospray (water with additive) that states:

"Although not recommended specifically for electrical risks, the fire extinguishers have passed the 35kv conductivity of discharge test, thus reducing operator risk if used in close proximity to electrical equipment."

Other than this I havent heard of any electrical safe water extinguishers?

I have heard of a foam extinguisher where the foam is not a constant spray so reduces the conductivity of the contents, but not water.

I am not so sure. It tends to be the initial pressure within the cylinder expelling the medium that knocks down the flames to put out the fire. I cant imagine this having the necessary force to cause this initial effect?
