Pipefitter electrocuted when closing metal gates at construction site in California.
NIOSH 1993 Apr; :1-2
A 30-year-old white male pipefitter (victim) was electrocuted while closing a steel chain link gate at a construction site. The victim was leaving the premises at the time of the incident, and was not wearing any personal protection equipment (PPE) other than work boots. An office/trailer which had been used by the construction crew as an office was located immediately adjacent to a freestanding (no post) chain link fence when the incident occurred. It was determined that the grounding wire in the office/trailer was not connected to provide effective grounding when the incident occurred. As a result of this, one side of the gate became energized from the freestanding fence and as the victim grabbed the other gate he completed the circuit to ground. The other gate (side opposite the office/trailer) had posts which ran into the ground. A co-worker pushed the victim from the gate and was shocked. Cardiopulmonary resuscitation was given by co-workers until paramedics arrived. The California FACE investigator concluded that, in order to prevent similar occurrences, employers should: 1. make sure all structures are grounded properly before allowing electricity to flow into them. 2. conduct jobsite surveys to identify potential hazards prior to beginning work on a project and during the project.
