6 0 Introduction 0.1 Process During the electrostatic coating process the non-ignitable liquid coating material is transported from a reservoir to an applicator where it is atomised by mechanical forces and by the influence of an electric field. The coating material is charged by high voltage of some 10 kV and a spray cloud is generated. The charged droplets of the coating materials are attracted by and applied to the earthed workpiece. Droplets of the coating material, which are not applied to the workpiece (overspray) are removed by a suction device or by other means. After the coating process the coated workpieces are introduced into a dryer or oven where a dry film of coating material is generated. 0.2 Fire hazards 0.2.1 Fire hazards can be caused by deposits of coating materials inside the spray booth, exhaust air ducts, the recovery system for coating materials, and filters. During operation, malfunctions or electrical faults may cause ignition of these residues. The propagation of the fire leads to hazards also in adjacent areas. 0.2.2 Particular attention should be paid to the prevention of electrostatic charges on different surfaces, which are in the vicinity of the spray cloud. This could apply both to workpieces during the coating process or the reciprocating devices and the mounting parts of the spraying system, etc. 0.2.3 When spraying non-ignitable coating material, the formation of an explosive atmosphere is not likely to occur. Electrostatic application equipment for ignitable coating materials are covered by EN 50050-1, EN 50050-2 and EN 50050-3. 0.3 Electric hazards 0.3.1 Electric shock (by direct or indirect contact) can be generated, for instance, by contact with — live parts, which are not insulated for operational reasons, — conductive parts, which are not connected to dangerous voltage during normal operation, but only in case of failure, — insulated live parts with insufficient or damaged insulation due to external impact, — charged passive parts with inadequate earthing. 0.3.2 Inadequate earthing may occur, for instance, due to — faulty connections to the protective earthing system, — a too high resistance to earth (e.g. contamination by coating materials). 0.3.3 Hazards could occur, for instance, if hazardous malfunctions (e.g. shortcut of electronic safety circuits) occur due to interferences of the electrostatic high voltage equipment and the components of the con
