Role of the Codes

The role of the North American HazLoc installation Codes (National Electrical Code for the U.S. and the Canadian Electrical Code for Canada) can be viewed as the starting point from which all subsequent aspects of the North American HazLoc system are derived. These Codes include details on equipment construction, performance and installation requirements, and area classification requirements.

For the U.S., the National Electrical Code (NEC) includes the following six Articles regarding hazardous locations (with additional Articles addressing special occupancies such as commercial garages, service stations, spraying applications and aircraft hangers):

  • Article 500 - General Class I, II, and III Division requirements
  • Article 501 - Specific Class I, Division requirements
  • Article 502 - Specific Class II, Division requirements
  • Article 503 - Specific Class III, Division requirements
  • Article 504 - Specific Class I, II, and III I.S. Division requirements
  • Article 505 - General and specific Class I, Zone requirements

For Canada, the Canadian Electrical Code (CEC) includes the following Rules, along with an Appendix, regarding hazardous locations (with subsequent Rules addressing special occupancies such as commercial garages, service stations, spraying applications and aircraft hangers):

  • Rule 18-000 - General Class I, Zone and Class II and III, Division requirements
  • Rule 18-090 - Specific Class I, Zone 0 requirements
  • Rule 18-100 - Specific Class I, Zone 1 and 2 requirements
  • Rule 18-200 - Specific Class II, Division requirements
  • Rule 18-300 - Specific Class III, Division requirements
  • Appendix J - General and specific Class I, Division requirements
