An apprentice and the supervising electrician this past week received a dangerous electric shock while re-terminating an electric supply line in an electrical cabinet. According to information, the apprentice electrician suffered electric shock when coming into contact with live unisolated electrical equipment.
The Regulator said that while in the process of re-terminating a 1000V outgoing (de-energised) supply cable at a pump starter box, an apprentice electrician has removed the shroud from the live side of the electrical isolator and inserted a T-handle tool to loosen bolts. The apprentice suffered an electric shock. The electrician then pulled the apprentice away and also suffered an electric shock.
Recommendations to industry: Effective supervision of apprentices in the workplace is essential. Isolation points must be determined to sufficiently remove people from energy sources.
