Laborer electrocuted in Indiana, August 4, 1987.
NIOSH 1987 Oct; :1-4
A general handyman was electrocuted when he touched an energized cap on a well casing. The victim was employed by a gas pipeline contractor who provided only on the job safety training. The company had moved into new facilities the day before the accident. In the new location, water was supplied by a well located about 100 feet from the facility. Four inch pipe encased the well with a submersible pump inside powered by a 220 volt line. A water leak had been observed in the area of the well casing. A backhoe was used to excavate around the casing, and the victim and his supervisor dug further but did not find the leak as the pump was not running and the water line was not pressurized. The men were standing in water when the pump automatically cycled on, giving a shock to the supervisor and causing the victim to slump over the well casing. The supervisor ran to the garage to break the circuit. Resuscitation was begun immediately but was unsuccessful. Investigation showed unsafe wiring powering the pump; where wires passed under the metal cap a damaged wire was noted, which energized the metal cap when the pump was running. It is recommended that employers implement a hazard recognition program, that electrical equipment be deenergized whenever possible during maintenance or repair work, and that compliance with existing articles of the National Electrical Code applying to branch circuit underground wiring be maintained.
