Review National Electrical Code Article 500 for hazardous (classified) location requirements. Also, review NFPA 497 which is the Recommended Practice for the Classification of Flammable Liquids, Gases, or Vapors and of Hazardous (Classified) Locations for Electrical Installations in Chemical Process Areas.
