These fire extinguishers are ABC type and can be used on A = trash, wood and paper, B = liquids and grease, C = electrical equipment. Only persons who have received fire extinguisher training should attempt to use a fire extinguisher to put out a fire or immediately call 997 and inform the civil defense. Never let the fire get between you and the exit. When using a fire extinguisher the acronym “P.A.S.S.“ should be applied, “P” Pull the tab, “A” aim the extinguisher at the base of the fire, “S” Squeeze the handle, and “S” Sweep the base of the flames. If you cannot extinguish a fire with one extinguisher, then leave the building and proceed to the assembly point.
