Ensures Proper Equipment Selection

James D., P.Eng., PMP

I enrolled in this course to gain a better understanding of hazardous area considerations, and to ensure my company and the people who worked under me were selecting equipment appropriately. One of the big take-aways I got from this course was a better understanding of how to handle simple devices (other apparatus items, such as thermocouples and simple non sparking devices). The topics that appealed to me most included the non-incendive and intrinsically safe topics as inspectors are not always consistent in their interpretation of the code. The course helped provide direction for several applications my company is currently working on. I liked that the testing material was spread throughout the course rather than just at the very end. During COVID restrictions, being able to take the course at home, on a flexible schedule was great.

Should Be Mandatory

Dan G, Electrical Safety Codes Officer's

It’s a great course. Hazardous Location electrical installs can pose dangerous explosion risk if not properly understood. This course should be mandatory for anyone who does design, inspecting, or electrical work in hazardous locations. A must for the Oil and Gas industry.

In-Depth Information

Kaylee T., P.Eng.

I started the Hazloc course with little prior knowledge of hazardous locations. The course provided a good overview and in-depth information. What I liked most about the course were the examples at the end of each chapter as this caters to my learning style. I am glad that I still have access to the course for 1 year so that I can reference back as needed.

Enhanced Knowledge

Terry L., P.Eng.

The course has enhanced my knowledge of hazardous locations classification and its importance to safeguard people, equipment and property if applied correctly. The course has also taught me about the nature of explosive atmospheres, properties of ignitable materials and gases, and mitigation methods to eliminate or reduce potential explosion hazards. It was also a good refresher to know the differences between the zone and division classification systems and the application of hazardous equipment certifications within these two systems. The course highlight was online accessibility at my convenience and the follow-up quizzes at the end of each unit for knowledge retention. The course offers good value.

Ensure Compliance to the CEC

Nicolas L., P.Eng., Chief Electrical Engineer

I have a passion for learning about hazardous locations. I’m the person responsible for ensuring compliance to the CEC. This course is about section 18, which is applicable to the industry I work in: the petrochemical industry. I’m also educating folks on HazLoc, so EngWorks is like training the trainer. People in my role have to have a HazLoc knowledge base. I recommend this course as a way to achieve that. I appreciate the ability to come back to review newly uploaded or revised videos. It’s like coming back to the latest revision of a textbook or reference guide. Another course highlight is how it’s sectionalized, so you don’t have to do it all in one sitting. There were some nuggets in the course I had no idea of before. The course is high quality. It’s from the expert. It’s like going to the farmer’s market and getting the fresh produce—the best stuff.
