What is the required clearance when operating near high voltage power lines rated at 33kV according to 1926.1408?

When operating near high voltage power lines rated at 33kV, the required clearance established by the OSHA standard 1926.1408 is indeed 10 feet. This standard is designed to minimize the risk of electrical hazards for workers and equipment in proximity to power lines.

The rationale behind this clearance requirement is to ensure safety by preventing accidental contact with the power lines, which could result in serious injuries or fatalities due to electrical shock or arc flash. The 10-foot distance serves as a buffer zone, recognizing the potential for unexpected equipment movement as well as maintaining a strategic distance from the electrical source.

Understanding this clearance requirement is essential for signal persons and operators, as it helps foster a safe working environment around overhead power lines. Proper adherence to these guidelines not only protects lives but also ensures compliance with safety regulations during construction or maintenance activities near electrical infrastructures.
