may occur.

HAZARD

Tells what the hazard is.

SAFEGUARDS

Tells how to avoid the hazard.

Spray Area

Fire Hazard

Improper or inadequate operation-

ing  and  maintenance  procedures 

will cause a fire hazard.

Protection against inadvertent arc-

ing that is capable of causing fire or 

explosion is lost if any safety inter-

locks are disabled during operation.  

Frequent power supply shutdown 

indicates a problem in the system 

requiring correction.

Fire extinguishing equipment must be present in the 

spray area and tested periodically.

Spray areas must be kept clean to prevent the accumula-

tion 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, flushing or maintenance.

When using solvents for cleaning:

Those used for equipment flushing should have flash 

points  equal  to  or  higher  than  those  of  the  coating 

material.

Those used for general cleaning must have flash points 

above 100

°

F (37.8

°

C).

Spray booth ventilation must be kept at the rates re-

quired by NFPA- 33, OSHA, and local codes.  In addition, 

ventilation must be maintained during cleaning opera-

tions using flammable 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 equip-

ment modifications may cause fire 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.
