High school maintenance worker electrocuted after contacting a 277 volt electrical cable.
NIOSH 1995 Nov; :1-4
On July 7, 1995, a 28-year-old male maintenance worker was electrocuted while working in a public school building. The incident occurred in the office area of a high school during the alteration of a wall for the construction of an alcove for a copying machine. The victim had just started the project and had removed a section of sheetrock when he discovered an electrical cable behind the wall leading from a light switch to the overhead fluorescent lights. He notified his supervisor who looked over the problem and instructed him to disconnect the power at the breaker box and to wait until he got back before he proceeded. After the supervisor left, the victim dismantled the light switch box and pulled the cable out of the wall. The victim was apparently stripping the wires on the cable when he contacted 277 volts, electrocuting him. NJDOH FACE investigators concluded that, in order to prevent similar incidents in the future, these safety guidelines should be followed: 1. Employers should develop, implement, and enforce an electrical lock-out, tag-out procedure. 2. Employers and employees should ensure that all electrical circuits are de-energized and tested before working on them. 3. Employers should be aware of educational and training resources for health and safety information.
