HAZARD
Tells what the hazard is.
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
cause a spark hazard. A spark
can ignite many coating mate-
rials and cause a fire or explo-
sion.
No. 2 Process Electric Motor Version - SAFETY
SAFEGUARDS
Tells how to avoid the hazard.
Parts being sprayed and operators in the spray
area must be properly grounded.
Parts being sprayed must be supported on
conveyors or hangers that are properly ground-
ed. The resistance between the part and earth
ground must not exceed 1 meg ohm. (Refer to
will
NFPA-33.)
Operators must be grounded. Rubber soled in-
sulating shoes should not be worn. Grounding
straps on wrists or legs may be used to assure
adequate ground contact.
Operators must not be wearing or carrying any
ungrounded metal objects.
When using an electrostatic handgun, opera-
tors must assure contact with the handle of the
applicator via conductive gloves or gloves with
the palm section cut out.
NOTE: REFER TO NFPA-33 OR SPECIFIC
COUNTRY SAFETY CODES REGARDING
PROPER OPERATOR GROUNDING.
All electrically conductive objects in the spray
area, with the exception of those objects re-
quired by the process to be at high voltage,
must be grounded. Grounded conductive floor-
ing must be provided in the spray area.
Always turn off the power supply prior to flush-
ing, cleaning, or working on spray system
equipment.
Unless specifically approved for use in hazard-
ous locations, all electrical equipment must be
located outside Class I or II, Division 1 or 2
hazardous areas, in accordance with NFPA-33.
