This skill module is part of a three-part series that introduces the core principles and concepts used for the installation of electrical equipment in hazardous (explosive) atmospheres.

Hazardous Area Classification in Oil and Gas Facilities discusses the process of Hazardous Area Classification, where we determine the risk of ignitable atmospheres being present. This skill module is relevant to both North American Standards (NFPA, NEC, CEC) and International Standards (IEC). 

Zone-based Equipment Selection and Installation in Oil and Gas Facilities covers equipment selection and installation practices for the Zone method used internationally (including North America).

Target Audience

Facilities and Project Engineers as well as newly graduated Electrical, Controls, and Instrument Engineers (0-5 years) with a need to improve basic understanding of instrumentation and control systems within oil and gas facilities.
