Course Catalogue.

After participating in this course, you will be able to:

• Obtain a fair understanding of hazardous area classifications, standards, equipment and wiring
• Familiarize yourself with industry standards and code requirements across Canada with comparisons to USA and Europe
• Apply prevalent technologies to mitigate hazards in classified areas, with emphasis on electrical and instrumentation equipment

Description
The requirements for electrical hazardous area classifications and associated wiring methods for safety interlocks for the storage, use and handling of flammable and combustible materials are defined in the Canadian Building Code (CBC), Canadian Electrical Code (CEC), National Electric Code (NEC) and National Fire Protection Association (NFPA). Industry datasheet and product workshops for electrical, instrumentation apparatus, barrier selection and wiring calculations for power limitations.
