Air Heater Assembly - Safety
AREA
Tells where hazards
may occur.
Spray Area /
High Voltage
Equipment
LN-9245-00.8
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 will
cause a spark hazard. A spark
can ignite many coating materi-
als and cause a fire or explo-
sion.
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 con-
veyors or hangers that are properly grounded.
The resistance between the part and earth
ground must not exceed 1 meg ohm. (Refer to
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, operators
must assure contact with the handle of the ap-
plicator 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 flooring
must be provided in the spray area.
Always turn off the power supply prior to flush-
ing, cleaning, or working on spray system equip-
ment.
Unless specifically approved for use in hazard-
ous locations, all electrical equipment must be
located outside Class I or II, Division 1 or 2 haz-
ardous areas, in accordance with NFPA-33.
