A tree surgeon suffered a powerful electric shock from an overhead power line while carrying out maintenance to hedges on a busy road near Royal Wootton Bassett.
The accident was caught on CCTV shortly after midnight on 19 January 2024 while Joshua Pocknell was working as part of a team of three on the A3102 when the mobile lighting tower he was pushing made contact with an overhead power line.
The 26-year-old said: “My whole body locked and I felt hot and cramping.
“I could hear the electricity in my head and thought I was going to die. I hit the floor and passed out, still cramping.
“I later discovered a hole had burnt through my arm and hip all the way to the bone.”
He had sustained life-threatening injuries and was rushed to hospital, where he spent the next five weeks.
No training in operating the mobile lighting tower
An HSE investigation into the incident found employer Upton Specialist Tree Services had requested a permit to carry out the work of a night time from Wiltshire Council. It had been decided to do the work after dark due to the needs of traffic flow as the A3102 acted as a diversion for the M4.
But the company had failed to adequately plan for or risk assess the dangers posed by overhead power lines. The company did not implement suitable control measures, such as barriers, instruction or training in operating the mobile lighting tower. Overhead powerlines had not been properly assessed or controlled, particularly following the change to night time working requiring the use of a mobile lighting tower.
Upton Specialised Tree Services Ltd, of Wimborne, pleaded guilty to safety breaches and was fined £60,000 and ordered to pay £6,237 in costs at Bristol Magistrates’ Court last week.
HSE inspector Tom Preston said: “Joshua is lucky to be alive.
“Overhead electrical power lines present extreme risks to workers, but the risks can and must be controlled.
“Work near overhead power lines should only be carried out where it can be done safely, following a suitable risk assessment, the use of barriers or safety zones, and proper training on the equipment being used.
“In this case, a worker sustained severe injuries in a traumatic incident for all concerned that was entirely preventable.”
