NFPA 33

NFPA 33 is the national fire protection standard for spray application using flammable and combustible materials, including powder coating processes. It outlines requirements for ventilation, electrical classification, fire suppression, and recirculation of exhaust air. Compliance with NFPA 33 reduces risks of fires, explosions, and health hazards while protecting both workers and facilities. Southern Fluid Systems engineers booths and ventilation systems that meet or exceed NFPA 33 standards, giving manufacturers peace of mind and smooth approval from authorities having jurisdiction (AHJs). Our expertise helps clients design and document code-compliant installations that support long-term safety and efficiency.
