Fatality Assessment and Control Evaluation (FACE) Report for Massachusetts: Elevator Service/Repair Helper Electrocuted, FACE-92-MA-010.

摘要

A 35 year old male elevator service/repair helper (victim) was electrocuted while installing a new electrical component on a commercial elevator car. During the course of this installation, the victim who was working unobserved, came into contact with an energized 110 volt electrical circuit supplying power to an operational single socket porcelain lighting fixture located on top of the elevator car. The victim was attempting connection of the component to the live branch circuit when he was jolted by the 110 volt current. Immediately shaking off the effect of the electrical charge, the victim resumed his work and collapsed approximately 50 - 60 minutes later while standing beside a co-worker inside the elevator car. The co-worker caught the victim as he pitched forward in the elevator car and immediately summoned facility medical personnel that included a company based physician. The victim was then transported to the local hospital where he was pronounced dead 1 hour and 40 minutes later. The Massachusetts FACE Investigator concluded that to prevent similar occurrences in the future, employers should: (1) Provide assurance that electrical systems are de-energized and tested to verify that they are de-energized prior to any work being performed on them. (2) Ensure proper lock out and tag procedures that are followed at all times. (3) Develop safety programs that provide a system of inspection and evaluation to ensure worker compliance with safe work procedures and ensure program effectiveness. (4) Consider use of battery powered electrical lighting systems when performing electricity related maintenance. (5) Implement a medical surveillance program that mandates employees suffering work related mishaps seek immediate medical attention regardless of severity.
