AREA
Tells where hazards
may occur.
HAZARD
Tells what the hazard is.
SAFEGUARDS
Tells how to avoid the hazard.
Spray Area /
High Voltage Equip-
ment
This is a high voltage device that
can produce electrical arcs ca-
pable of igniting coating materials.
Parts being sprayed must be supported on convey-
ors or hangers and be grounded. The resistance
between the part and ground must not exceed 1
megohm. (Reference NFPA-33.)
A safe distance must be maintained between the
parts being coated and the atomizer bell. A distance
of at least 1 inch for each 10 KV of power supply
output voltage is required at all times.
Parts must be supported so that they will not swing
and reduce the clearance specified above.
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.
Unless specifically approved for use in hazardous
locations, the power supply and other electrical
equipment must not be used in Class I, Division 1
or 2 locations.
Explosion Hazard/
Incompatible Materi-
als
Halogenated hydrocarbon sol-
vents for example: methylene
chloride and 1,1,1,-Trichloroeth-
ane are not chemically compatible
with the aluminum that might be
used in many system compo-
nents. The chemical reaction
caused by these solvents react-
ing with aluminum can become
violent and lead to an equipment
Aluminum is widely used in other spray application
equipment - such as material pumps, regulators,
triggering valves, etc. Halogenated hydrocarbon
solvents must never be used with aluminum equip-
ment during spraying, flushing, or cleaning. Read
the label or data sheet for the material you intend
to spray. If in doubt as to whether or not a coating
or cleaning material is compatible, contact your
material supplier. Any other type of solvent may
be used with aluminum equipment.
