Ensure an effective policy is in place for the control of the hazard of exposure to low-voltage electricity, including requiring elimination as the primary control.
On the day of the incident, landowners in the Cardrona Valley were in the process of having the overhead lines on their property replaced with underground cables which would run from a new metre which would be connected to existing overhead lines at the top of a pole.
The victim, then employed by the Defendant as a line mechanic, was at the property to complete the connection. The victim ascended a ladder to carry out work at the top of the pole. The ladder was not tied to the pole. The victim did not disconnect the power supply before working on the line. He started the task of connecting the neutral wire to the main wire by way of parallel groove clamp using an adjustable crescent. As the victim attempted to tighten the clamp with the crescent he made contact with the line causing a low voltage arc.
The resulting arc and flashover caused the victim to fall from the ladder to the ground, approximately 6 metres below. He suffered compound tibia and fibula fractures to his left leg and a fractured L2 lumbar vertebra.
