What is one method of worker protection from step touch potential?

The concept of step touch potential refers to the difference in electric potential that can occur when a person is in close proximity to an energized electrical source. Essentially, if a person steps too close to an energized line or equipment, the ground beneath them can carry a voltage, leading to a potentially dangerous situation.

Grounding vehicles together is a method that can help mitigate the risk of step touch potential. When vehicles are grounded and connected to the same electrical reference, it helps eliminate any potential difference between them and the ground, thus reducing the risk of electrical shock if a worker steps between them.

Choosing this method acknowledges the importance of maintaining a safe, electrically grounded environment in areas where workers may come into contact with potential electrical sources, thereby enhancing overall safety on-site.
