Foam hearth extinguishers is often distinguished by their cream colour coded panel.
Carbon dioxide or Co2 hearth extinguishers are Safe and sound to employ on electrical fires. The Co2 fuel is non-conductive and does not leave a residue guiding that will influence the long run functionality of electrical tools not like foam or powder extinguishers.
