The obligation
PCBUs must identify ignition sources, establish exclusion zones, ensure adequate ventilation, and use only compliant electrical equipment in spray areas.
Spray painting involves flammable solvents that create explosive atmospheres. The Code requires PCBUs to: classify hazardous areas, eliminate or control ignition sources, maintain exclusion zones (Appendix B provides sample zones and ventilation conditions), use only explosion-proof electrical equipment, and have fire suppression and emergency response plans in place. Powder coating also presents fire and dust-explosion risks requiring similar controls.
