Please note that it is a requirement for all attendees to sign a "Confidentiality Agreement" prior to receiving the course notes for this online offering.

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

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.

Who Should Attend
Plant Managers and Engineers • Project Engineers • Engineers in Training • Technologists • Electricians • Electrical Designers • Chemical Process Operators • Equipment personnel
