Reduce fire and explosion hazards for workers with the 2016 NFPA 33: Standard for Spray Application Using Flammable or Combustible Materials.

Protect workers by addressing fire, explosion, and electrical hazards in industries that spray flammable and combustible liquids, including waterborne materials that contain flammable or combustible residues. NFPA 33 has the latest rules for the construction of spray rooms, spray booths, and spray areas, along with their electrical installations, ventilation, and fire protection systems; and for safe spray application of coatings, including handling of flammable liquids, operations, and maintenance. NFPA 33 requirements address automated and hand-held spray application processes, as well as specific requirements for electrostatic and powder coating spray systems. The Standard also includes specific requirements for hand lay-up and spraying operations for glass fiber-reinforced plastics.

The 2016 NFPA 33 helps engineers, designers, contractors, and installers address fire and electrical safety concerns more effectively.

• Protections for new scrubber technologies help companies protect their workers and pass safety inspections.
• Terminology correlates with NFPA 70®: National Electrical Code® (NEC®). Other text changes impact electrical classifications for outside automatic spray operations, and additional graphics help you understand electrical classification requirements.
• A first-time chapter on Spray Application in Membrane Enclosures provides a flexible new means for compliance. The enclosures can be used indoors and outdoors to enclose workpieces that do not fit in traditional spray booths.
• The term "secondary filter" is now "recirculation filter" and has been clarified to define this type of filter and indicate when it is allowed.
• Combustible dust fire protection requirements and rules for sprinklers in ducts have been clarified to help users improve fire protection.
• Annex material provides new guidance in determining the water supply requirement for all sprinklers likely to open in a single fire incident.
• Minimum Explosive Concentrations (MECs) for representative powder coatings have been validated with recent test data, and updated Annex C contains metallic coating MECs.

Protect lives in facilities where flammable or combustible liquids or combustible powders are sprayed. Follow the industry best practices with the 2016 edition of NFPA 33.
