Refrigeration Addendum

This addendum contains new learning objectives and content in refrigeration safety based on the recommendations made by Technical Safety British Columbia (TSBC) in its investigation reports of the October 2017 ammonia leak. The report examines two ammonia leaks, one occurring at the Fernie Memorial Arena in Fernie, BC, which resulted in the deaths of three people, and the other in October 2018 at a pet food manufacturing plant in Langley, BC, which prompted an extensive evacuation of the area. As this information is critical to operator safety, IPECC, SOPEEC, and PanGlobal Training Systems are making it available to learners immediately at no additional cost. In addition, this material will also be published in the forthcoming editions of Power Engineering Fourth Class, Power Engineering Fifth Class, and Refrigeration Plant Operator.

The new content of this addendum emphasizes the testing of secondary refrigeration systems, safe operation of ammonia refrigeration systems, and maintenance of refrigeration equipment. Some content may be familiar from the courses mentioned above, and the TSBC investigations suggest that it is worth repeating if this content will contribute to keeping all Power Engineers and operators safe.
