The employee of a civil engineering contractor was erecting a mobile lighting unit under an 11,000 Volt overhead power line that was 8 metres above ground. The lighting unit made contact with the overhead power line and the employee sustained a fatal electric shock. The live overhead line had not been adequately highlighted to workers.
The company was prosecuted under the Health and Safety At Work etc. Act 1974, Section 3, Sub Section 1 and received a fine.
The downloadable guidance Avoidance of danger from overhead electric power lines describes how to work safely near overhead power lines in a range of industries. You can also download a free leaflet called Safe working near overhead power lines in agriculture.
