HAZARDOUS LOCATIONS

There are many industries where combustible vapors and dusts are used or processed creating a potentially explosive environment.  Electrical equipment for use in these areas needs to be properly certified and installed to prevent ignition of these atmospheres.

We have over 30 years of experience confirming compliance of equipment and systems with the applicable requirements of the following standards.

NFPA 70 – The National Electrical Code – Articles 500 through 517
CSA 22.1 – The Canadian Electrical Code – Section 18, 20 and Annex J

NFPA 30 –  Flammable and Combustible Liquids code
NFPA 52 – Vehicular Gaseous Fuel Systems Code
NFPA 496 – Purged and Pressurized Electrical Equipment
NFPA 497 – Recommended Practice for the Classification of Flammable Liquids, Gases, or Vapors and of Hazardous (Classified) Locations for Electrical Installations in Chemical Process Areas
NFPA 499 – Recommended Practice for the Classification of Combustible Dusts and of Hazardous (Classified) Locations for Electrical Installations in Chemical Process Areas
ANSI ISA 12.12.01  – Hazardous location Equipment for Installation in Div 2 Locations
ANSI ISA/RP 12.06.01 – Intrinsically Safe Wiring Methods
