Line-construction contractors can do their best to train the management, offer safety training and equipment and trust the foremen who are appointed to a job, but it is an inherently dangerous business. Despite all the safeguards, some new linemen say this is what some foremen tell them about safety procedures: “That’s the way you may have learned it in training, but this is how it’s done on the job...”
Training is designed to keep linemen safe. But is that training and equipment being put to proper use? The answer varies depending on the job and the foreman—more so than the...

Step Potential

Step potential is the step voltage between the feet of a person standing near an energized grounded object. It is equal to the difference in voltage, given by the voltage distribution curve, between two points at different distances from the electrode. A person could be at risk of injury during a fault simply by standing near the grounding point.

Touch Potential

Touch potential is the touch voltage between the energized object and the feet of a person in contact with the object. It is equal to the difference in voltage between the object and a point some distance...
