Title Electrostatic charging in the course of high pressure, airless spraying and prevention of the probable accidents

Abstract Measurements were made, in the laboratory and at work sites, of the degree of charging of paint mist, the maximum spark discharge energy and the safety of working conditions during high-pressure airless paint spraying. Charge build-up and separation occurred in the space between the spray gun and the workplace, and on the workpiece. The differences in charge potential and static accumulation were great enough that the energy of a probable spark discharge could exceed the minimum ignition energy of the paint mist. Charge accumulation and spark discharge can be prevented by grounding of the workpiece and charge drainage through an eliminator. Dangers of personal charging are minimised by conductive clothing, footwear and flooring.
