Abstract
A safety harness for use with an electrostatic spray paint gun is disclosed which fits over the feed tube and the barrel of a standard electrostatic spray gun and acts both to protect the hand of the spray gun operator from an electrostatic discharge and to provide an indication of the electrostatic operation of the spray gun. A T-shaped safety shield made of non-conductive material is placed over the portions of the spray gun which may develop an electrostatic charge thereon, and is held onto the spray gun by mating strips of material. Located on the inner surface of the safety shield is a thin sheet of conductive foil which acts to channel the discharge through a wire to illuminate an indicator light located remote from the spray gun in a highly visible position.
