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.
Chemical Hazard
Certain materials 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
or applicable country codes, hazardous areas in
accordance with NFPA 33 and EN 16985.
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 Safety Data Sheet
supplied by coating material manufacturer.
Adequate exhaust must be provided to keep the air
free of accumulations of toxic materials. Reference
EN 12215 or applicable code.
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.
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.
