Electric shock incident; LTI during lifting operations

摘要

A member has reported an incident in which a ship's electrician received a 220V AC shock. The incident occurred when working on a 24V remote input/output (RIO) module on joystick electrical equipment. The electric shock was transmitted from the left hand to right hand due to the fact that the path of least resistance was across the body and to ground through the factory-fitted anti-static earth strap. The electrician suffered minor burns to the left hand. The company noted the following: 1. live conductors should not be present at work sites if the correct controls are in place and advice from the manufacturers of electrical equipment is always properly followed 2. personal risk assessments were not adequate due to complacency in the task to be undertaken 3. harm could be caused to any person when they are exposed to 'live parts' that are either touched directly or indirectly by means of some conducting object or material.
