Serial Digital Module - Safety
AREA
Tells where hazards
may occur.
Spray Area
HAZARD
Tells what the hazard is.
Fire Hazard
Improper or inadequate operation
and maintenance procedures will
cause a re hazard.
Protection against inadvertent
arcing that is capable of causing
re or explosion is lost if any safety interlocks are disabled during
operation. Frequent power supply shutdown indicates a problem
in the system requiring correction.
SAFEGUARDS
Tells how to avoid the hazard.
Fire extinguishing equipment must be present in
the spray area and tested periodically.
Spray areas must be kept clean to prevent the accumulation of combustible residues.
Smoking must never be allowed in the spray area.
The high voltage supplied to the atomizer must be
turned off prior to cleaning, ushing or maintenance.
When using solvents for cleaning:
Those used for equipment ushing should have
ash points equal to or higher than those of the
coating material.
Those used for general cleaning must have ash
points above 100oF (37.8oC).
Spray booth ventilation must be kept at the rates
required by NFPA-33, OSHA, and local codes. In
addition, ventilation must be maintained during
cleaning operations using ammable or combustible
solvents.
Electrostatic arcing must be prevented.
Test only in areas free of combustible material.
Testing may require high voltage to be on, but only
as instructed.
Non-factory replacement parts or unauthorized
equipment modications may cause re or injury.
If used, the key switch bypass is intended for use
only during set-up operations. Production should
never be done with safety interlocks disabled.
Never use equipment intended for use in waterborne installations to spray solvent based materials.
The paint process and equipment should be set up
and operated in accordance with NFPA-33, NEC,
and OSHA requirements.
