Since the foam extinguisher is non-conductive and analyzed into the BS EN3 35,000V dielectric examination, they may be utilized in the vicinity of but not on Are living electrical gear. Foam fire extinguishers can be distinguished by their product colour coded panel.

Carbon dioxide or Co2 hearth extinguishers are Secure to utilize on electrical fires. The Co2 gas is non-conductive and would not leave a residue driving that may result the longer term general performance of electrical gear not like foam or powder extinguishers. These hearth extinguisher styles also are helpful on Course B fires (flammable liquids). Carbon dioxide fireplace extinguishers are distinguished by a black panel about the extinguisher physique and by their horn and that is to get pointed at the fire but not held in the event of a freeze burn.
