Laborer electrocuted while working at bottom of dry well at sewer pumping station.
NIOSH 1991 Oct; :1-5
On August 28, 1990, a 31-year-old male laborer was killed, apparently as a result of contact with equipment thought to be deenergized. Working at the bottom of a 24-foot deep dry well at a sewer pumping station, the victim backed into the frame of a disconnected heater and apparently received an electric shock of a least 0.53 volts AC, sufficient to have caused an electric shock. Careful monitoring of electrical components in the area revealed ground faults which caused the wall heater frame to be energized. FACE investigators concluded that, in order to prevent similar occurrences in the future, employers should: 1. ensure that electrical equipment within pumping stations are periodically inspected and repaired by a licensed electrician conduct a job site survey before starting any job to identify potential hazards and implement appropriate control measures; 2. develop and implement an electrical safety program to help workers recognize and control hazards; 3. ensure that workers entering a confined space, such as the dry well at the pumping station, observe appropriate safety measures; 4. have at least one person assigned the responsibility for overseeing safe work practices and safety education; 5. provide training in basic CPR.
