Electricity Today T&D Magazine

Ineffective or missing fall protection has been OSHA’s most-cited violation every year since 2011, and falls are the leading cause of death in the construction industry. Year after year, fall protection remains a key concern for employers throughout the United States. Not just that, but electrical workers routinely face hazards in the form of high-voltage equipment, dangerous heights, and extreme weather conditions.

OSHA recognizes these dangers and in 2014, updated some of its fall protection regulations to keep employees safe while working at heights. 29 CFR §1926.954 covers PPE requirements, including fall protection, and 29 CFR §1910.269 covers electric power...

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...
