Analysis of Two Electrocution Accidents in Greece that Occurred due to Unexpected Re-energization of Power Lines.

Baka AD, Uzunoglu NK - Saf Health Work (2014)

Bottom Line: Investigation and analysis of accidents are critical elements of safety management.The over-riding purpose of an organization in carrying out an accident investigation is to prevent similar accidents, as well as seek a general improvement in the management of health and safety.This study presents and analyzes two electrical accidents (1 fatal injury and 1 serious injury) that occurred because the power supply was reconnected inadvertently or by mistake.

ABSTRACT
Investigation and analysis of accidents are critical elements of safety management. The over-riding purpose of an organization in carrying out an accident investigation is to prevent similar accidents, as well as seek a general improvement in the management of health and safety. Hundreds of workers have suffered injuries while installing, maintaining, or servicing machinery and equipment due to sudden re-energization of power lines. This study presents and analyzes two electrical accidents (1 fatal injury and 1 serious injury) that occurred because the power supply was reconnected inadvertently or by mistake.

Mentions: The described electrocutions occurred because of unexpected activation of power lines. When a person receives an electric shock, electricity flows between parts of the body or through the whole body to the ground or the earth. The victim is electrocuted due to direct contact with energized equipment such as distribution box circuit, switches, fuses, or energized wire. The failure to de-energize was the only cause of these accidents (see Fig. 1). The second parallel series of cause blocks indicate that poor working practice (no work instructions, inadequate safeguards, lack of communication, etc.) touched a live part that could electrocute the body parts that are not currently covered by personal protective equipment (e.g., safety gloves and safety boots). The victim was also in touch with the ground and did not wear proper personal equipment when he touched the bare conductors. Therefore preventing injuries is extremely difficult in the absence of an understanding of the factors which are likely to favour the occurrence of accidents. By studying such factors, the root causes of accidents can be isolated and necessary steps can be taken to prevent the recurrence of the accidents.
