Area Classification For Hazardous Locations

Area Classification Drawings

Areas containing flammable vapours and combustible dusts must comply with Sections 18 & 20 of the Canadian Electrical Code (Part I). The Owner/Employer in a facility is required to identify hazardous locations where the risk of ignition of vapours, dusts or fibres / flyings exists, and take measures to ensure that the electrical equipment and wiring methods comply. Identifying these areas is the first step and could save thousands in unnecessary upgrades.

CCP Engineering can provide area classification drawings, signed & sealed by a professional engineer, using guidance from the Ontario Electrical Code, NFPA, UL, FM Global and IEC Standards. We utilize calculations methods that take in to account the amount of exhaust ventilation provided, which often results in Zone 0 and Zone 1 volumes being very small and manageable.

We provide easy-to-understand drawings with details on Classification, Division (or Zone), Group and Temperature Code.

The following is a link to Bulletin 18-1-16 from the Electrical Safety Authority on an Inspector's role in reviewing a hazardous location and the client's responsibility to obtain an area classification drawing: Bulletin 18-1-20
