FIRE, EXPLOSION, OR ELECTROSTA
TIC SHOCK HAZARD
To reduce the risk of fire, explosion, or electrostatic shock,
may result from electrical discharge, it is essential that:
All parts of the electrostatic system are properly grounded.
S All personnel in or close to the spray area are properly
electrically conductive objects or devices in the spray area,
paint containers, wash
cans and tools, are properly
When operating the electrostatic device, any ungrounded
objects in the spray area (such as people, containers, tools,
can become electrically charged. Arcing may
occur if these
then come in contact or close to ground. Arcing of suf
cient energy levels can ignite the fluid being sprayed, fumes
solvents, dust particles, and other flammable substances.

States Government safety standards have been adopted under the Occupational
Safety and Health Act. These standards––particularly the
General Standards, Part 1910.107 and any other appropriate regulations––should be consulted in connection with the installation, operation, and
maintenance of electrostatic spray painting equipment.
