Description

Reduce fire and explosion hazards for workers with the 2011 NFPA 33: Standard for Spray Application Using Flammable or Combustible Materials.

Boost fire safety on the job with the latest rules for the construction of spray rooms and spray booths, along with their electrical systems, ventilation, and fire protection systems, and for safe spray application of coatings, including handling of flammable liquids, operations, and maintenance. The 2011 edition of NFPA 33 provides requirements for automated and hand-held spray application processes, as well as specific requirements for electrostatic spray systems. NFPA 33 also includes specific requirements for hand lay-up and spraying operations for glass fiber-reinforced plastics.

Revisions in the 2011 edition that improve fire prevention and fire protection include:

Addition of exemptions for small quantity operations
Inclusion of a decision tree to assist in determining applicability of NFPA 33
Revision of the definition of spray area to better describe its extent
An improved correlation with the NEC® zone system for classifying hazardous locations
A reduction in the extent of hazardous (classified) areas outside spray booths and rooms, based on incident history and risk analysis
Incorporation of NFPA 30’s concept of maximum allowable quantity (MAQ) and storage quantity limits based on these MAQs
Changes to requirements for spray booths and rooms that are also used for drying and curing operations

Don’t take chances with flammable or combustible liquids or combustible powders. Put industry best practices to work for you with the 2011 NFPA 33.
