Electrical Work

Electrical work is a broad occupational category including tasks such as installing, maintaining, and repairing electrical controls, wiring and work on lighting systems. Electrical work may also entail general electrical maintenance, inspection of transformers and circuit assemblies, and assembly of cable harnesses. In addition, electrical work can include installation and maintenance of overhead distribution and transmission systems, underground cables and electrical equipment. Among the most significant risks workers face are electrocutions, arc flash incidents, incidents caused from machine energization, and fires or explosions.

The information in each section below is listed in the order of relevance to the hazardous situation.
