For unknown voltage situations, what is the minimum distance a worker should maintain?

The minimum distance a worker should maintain from unknown voltage situations is 20 feet. This distance is based on safety protocols designed to protect individuals from potential electrical hazards caused by unidentifiable voltage sources. Maintaining a distance of 20 feet ensures enough space to reduce the risk of electrical shock or arc flash incidents, which can occur if someone inadvertently comes into contact with or is too close to high-voltage equipment.

This distance is aligned with standard safety practices in the industry, which recognize that increased proximity to electrical hazards raises the likelihood of accidents. Workers should always prioritize maintaining a safe distance when dealing with unknown voltage situations, as it helps mitigate the risk of injury or fatality.
