Generally speaking, all facilities using potentially explosive materials require a documented hazardous area analysis and classification. This includes process industries involving potential combustible dusts, which require a Dust Hazard Analysis (DHA) to be conducted. Our consultants can assist with performing and documenting these area classifications for your facility.
Our experience is too extensive to fully describe. Below is a partial list of of the area classification (and related) standards we have used:
NFPA |
NFPA 30: Flammable and Combustible Liquids Code |
|
NFPA 33: Standard for Spray Application Using Flammable or Combustible Materials |
|
NFPA 34: Standard for Dipping and Coating Processes Using Flammable or Combustible Liquids |
|
NFPA 35: Standard for the Manufacture of Organic Coatings |
|
NFPA 36: Solvent Extraction Plants |
|
NFPA 61: Fires and Dust Explosions in Agricultural and Food Processing Facilities |
|
NFPA 70: National Electrical Code |
|
NFPA 484: Standard for Combustible Metals |
|
NFPA 497: Recommended Practice for the Classification of Flammable Liquids, Gases, or Vapors and of Hazardous (Classified) Locations |
|
NFPA 499: Recommended Practice for the Classification of Combustible Dusts and of Hazardous (Classified) Locations for Electrical Installations in Chemical Process Areas |
|
NFPA 652: Fundamentals of Combustible Dusts |
|
NFPA 654: Prevention of Fire and Dust Explosions from the Manufacturing, Processing and Handling of Combustible Particulate Solids |
|
