AREA
Tells where hazards
may occur.
HAZARD
Tells what the hazard is.
SAFEGUARDS
Tells how to avoid the hazard.
High voltage equipment is
utilized in the process. Arcing
in the vicinity 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 shut-
down indicates a problem in
the system which requires
correction.
An electrical arc can ignite
coating materials and cause a
fire or explosion.
Unless specifically approved for use in
hazardous locations, the power supply, control
cabinet, and all other electrical equipment must
be located outside Class I or II, Division 1 and
2 hazardous areas in accordance with NFPA-33
and EN 50176.
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
circuits disabled.
Before turning the high voltage on, make sure no
objects are within the sparking distance.
Electrical Discharge
Electrical
Equipment
Certain materials may be
harmful if inhaled, or if there is
contact with the skin.
Follow the requirements of the Safety Data Sheet
supplied by coating material manufacturer.
Adequate exhaust must be provided to keep the
air free of accumulations of toxic materials.
Use a mask or respirator whenever there is a
chance of inhaling sprayed materials. The mask
must be compatible with the material being
sprayed and its concentration. Equipment must
be as prescribed by an industrial hygienist or
safety expert, and be NIOSH approved.
Chemical Hazard
Toxic Substances
Spray applicators require that aluminum inlet
fittings be replaced with stainless steel.
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
equipment 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 coating supplier. Any other type of
solvent may be used with aluminum equipment.
Halogenated hydrocarbon
solvents for example:
methylene chloride and
1,1,1,-Trichloroethane are
not chemically compatible
with the aluminum that
might be used in many
system components. The
chemical reaction caused
by these solvents reacting
with aluminum can become
violent and lead to an
equipment explosion.
