The range prior to the ‘B’ is often a relative evaluate of the area the extinguisher can address for Course B fires, which entail flammable liquids and gases. This number gives a sign of your extinguisher’s efficiency in managing flammable liquid fires.

Inside the nineteen forties, Germany invented the liquid chlorobromomethane (CBM) to be used in aircraft. It absolutely was simpler and slightly considerably less toxic than carbon tetrachloride and was employed until finally 1969.
