The fire broke out while a watch cleaning machine was in operation at the close of the last year at a watch store in Shizuoka City. The cause of its fire seems to be the static spark of electric charge stored in the various cleaning liquids and other parts. Then, if the phenomenon of the static carrying charge exits in them, it would be desirable to measure the amount from the point of preventing fire danger. So the amounts of these liquids and other parts have been measured.Experiments for gasoline, benzine petrol, carbon tetrachloride and trichlorethylene were made by the set which has the valve 1R5 as the amplifier.The absolute values of carrying charges are maximum in benzine petrol and minimum in trichlorethylene. Then, methods of prevention of fire danger have been established.
