Arc-Flash Analysis

A study of particular importance due to employee safety and provincial regulations is called Arc-flash analysis. Many industries are required to quantify the risk involved working on or near energised electrical equipment – an arc-flash study does just that.


Operating and Electrical technicians have potential occupational hazards where they can be severely burned by an arc-flash incident – very high energy released during a fault. This may occur during routine switching or troubleshooting tasks.


Operators run the electrical process equipment and are responsible to turn it on and off. Electricians maintain the equipment and at times must troubleshoot with the circuits live. Both of these scenarios require an arc-flash analysis, safe work procedures and training to reduce the consequences of an arc-flash hazard and to comply with provincial regulations.


An arc-flash study quantifies the available energy levels - additional engineering can reduce these levels as required. Revisions to and/or the creation of electrical safe work procedures will help prevent a workers exposure. One can’t prevent all arc-flash incidents, but following these steps will facilitate less injury to the worker and compliance with the latest CSA Z462-15 (2015) Workplace Electrical Safety Standard.


QSR Electrical Engineering works with members of Operations, Maintenance, Reliability, Engineering and Health & Safety. Each shall realise the hazards and methods to manage the risks. Electrical Awareness and arc-flash training recommendations can be provided.


The success of any program depends largely on the aspirations of those involved. QSR Electrical Engineering has high aspirations to protect workers working on or near electrical equipment and keep them safe.
