This article highlights OSHA’s requirements for substations and work within substations. Substations have significant step and touch and arc flash hazards located within relatively small, restricted areas. Various types of non-electrical and electrical work are performed inside areas with extremely high voltages and minimal air clearances. Energized substations are considered restricted work areas that contain electric power system hazards with extremely high risk. Workers who enter restricted work areas must be appropriately trained to recognize the electrical hazards and to demonstrate the...

Electrical testing hazards arise when specialty testing is performed on electric power lines and equipment to determine maintenance needs and fitness for service. OSHA requirements for testing and test facilities are found at 29 CFR 1910.269(o) and 1926.963. Specialty testing refers to cable fault locating, large capacitive load tests, high-current fault closure tests, insulation-resistance and leakage tests, direct-current proof tests and other tests requiring direct connection to power lines. These tests include interim measurements using high-voltage and/or high-power methods on new lines...

These items must be appropriately used and cared for to maintain their insulating capabilities. This article will address two unique areas of electric power regulatory standards: electrical protective equipment and live-line tools. As with all articles in this series, let’s start with the hazard. Electric power workers have exposure to electric shock hazards with extremely high risk of serious injury or death. Although personal protective equipment should always be considered the last line of control, electrical protective equipment – when designed, manufactured, tested, maintained and used...
