Abstract
On June 17, 1994, a 33-year-old service technician was electrocuted by 220 volts A.C. while repairing a central air condenser unit located outside a residence. The victim had repaired a leak in the condenser coil and was preparing to check for electrical faults. He was kneeling on moist ground in front of the open side of the unit and was in contact with the case on the side of his abdomen. Later testing of the unit revealed that the compressor unit had an internal short, subsequently electrifying the case. The ground wire to the casing had been removed by the victim, and when the compressor shorted out, the victim provided the path-to-ground and suffered a fatal electrical shock. The MO FACE Investigator concluded that in order to prevent similar occurrences, employers should: 1. require that all electrical equipment be de-energized before any repairs are performed; 2. provide employees with education and training in the recognition and avoidance of electrical hazards; 3. ensure that electrical equipment is installed to meet the manufacturers specifications, and ensure that equipment is restored to the manufacturers specifications before any work is begun.
