Spray Area / High Volt-
age Equipment
Electrical Discharge
There is a high voltage device that can
induce an electrical charge on ungrounded
objects which is capable of igniting coating
materials.
Inadequate grounding will cause a spark
hazard. A spark can ignite many coating
materials and cause a fire or explosion.
Follow These Guidelines
Parts being sprayed must be supported on conveyors
or hangers and be grounded. The resistance between
the part and ground must not exceed 1 mega ohm.
All electrically conductive objects in the spray area, with
the exception of those objects required by the process
to be at high voltage, must be grounded.
Any person working in the spray area must be ground-
ed.
Unless specifically approved for use in hazardous
locations, the power supply and other electrical control
equipment must NOT be used in Class I, Division 1 or
2 locations.
Electrical Discharge
High voltage equipment is utilized. Arcing in
areas of flammable or combustible materials
may occur. Personnel are exposed to high
voltage during operation and maintenance.
Protection against inadvertent arcing that
may cause a fire or explosion is lost if safety
circuits are disabled during operation.
Frequent power supply shutdown indicates
a problem in the system which requires
correction.
An electrical arc can ignite coating materials
and cause a fire or explosion.
Electrical Equipment Follow These Guidelines
All electrical equipment must be located outside Class
I or II, Division 1 or 2 hazardous areas. Refer to NFPA
33, 2009 Edition.
Turn the power supply OFF before working on the
equipment.
Test only in areas free of flammable or combustible
material.
Testing may require high voltage to be on, but only as
instructed.
Production should never be done with the safety cir-
cuits disabled.
Before turning the high voltage on, make sure no ob-
jects are within the sparking distance.
