HAZARD
Tells what the hazard is.
Electrical Discharge
High voltage equipment is uti-
lized in the process.
in the vicinity of flammable or
combustible materials may oc-
cur. 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 correc-
tion.
An electrical arc can ignite coat-
ing 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 sol-
vents for example: methylene
chloride and 1,1,1,-Trichloro-
ethane are not chemically com-
patible with the aluminum that
might be used in many system
components.
The chemical
reaction caused by these sol-
vents 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 hazard-
ous locations, the power supply, control cabinet,
Arcing
and all other electrical equipment must be locat-
ed outside Class I or II, Division 1 and 2 hazard-
ous 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 combus-
tible 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 manu-
facturer.
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 ap-
plication 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.
