3. Shut down immediately in event of fire.

4. Maintain ground circuit on all conductive objects below 1 megohm to prevent

sparking.  (ANSI/NFPA 33, Chapter 9, or local codes).

5. Shut down operation and correct grounds if sparking occurs.

6. Install fixed fire suppression system in accordance with ANSI/NFPA 33,

Chapter 7 (or local codes), before operating with combustible powder.

7. Install automatic flame detectors in accordance with ANSI/NFPA 33,

Chapter 7 (or local codes), before operating automatic guns

surface must be conductive.  Footwear and gloves must be static dissipative

in accordance with ANSI Z41-1991 (or local codes).

11. Air velocity through all booth openings must meet local requirements and

contain powder within the booth.  If powder escapes from the booth, shut

down operation and correct the malfunction.

12. Powder may be toxic or be a nuisance dust hazard.  Refer to supplier’s

MSDS.  If exposed to dust during operation, maintenance, or clean up,
