HAZARD
Tells what the hazard is.
Electrical Discharge
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.
Certain material may be harmful
if inhaled, or if there is contact
with the skin.
Explosion Hazard –
Incompatible Materials
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.
SAFEGUARDS
Tells how to avoid the hazard.
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.
Follow the requirements of the Material
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.
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.
