Lessons from a Near-Fatal Incident: Ensuring Safety and Statutory Compliance Around Overhead Powerlines

Imagine a split second where your entire body locks up, a blinding surge of heat rips through your limbs, and you can hear the raw hum of electricity echoing inside your own head. For 26-year-old Joshua Pocknell, this terrifying scenario became a reality while carrying out routine evening clearance work on a Wiltshire road.

A mobile lighting tower he was moving made direct contact with an 11,000-volt overhead powerline. The resulting shock left him with catastrophic, life-threatening injuries, including deep thermal burns that charred his arm and hip completely to the bone. Following five weeks of complex surgeries and facing lifelong chronic nerve pain, Joshua's career was instantly cut short.

This incident resulted in a decisive Health and Safety Executive (HSE) prosecution. On 1 May 2026, Bristol Magistrates' Court ordered the employer to pay a £60,000 fine plus £6,237 in costs after pleading guilty to breaching Regulation 14 of the Electricity at Work Regulations 1989.

As a professional firm specialising strictly in commercial and industrial compliance, we believe this traumatic event provides critical safety lessons that every facility manager, duty holder, and site supervisor must implement today.

The Root Cause: A Total Failure to Risk Assess

The HSE investigation revealed that while the company had successfully obtained a local authority permit to execute the midnight vegetation clearance, they had failed completely to risk assess or plan for the dangers of nearby high-voltage lines. No safety zones were mapped, no physical goalpost barriers were erected, and the crew had received zero training on the safe deployment height of mobile lighting towers near live conductors.

When operating plant hire, scaffolding, or mobile access platforms on commercial premises, overhead powerlines must never be treated as passive background infrastructure. High voltages can easily arc across open air gaps to conductive equipment without requiring direct physical contact.

Statutory Responsibilities Under Regulation 14

Regulation 14 of the Electricity at Work Regulations 1989 sets out a clear, absolute legal standard: No person shall be engaged in any work activity on or near any live conductor unless it is absolutely necessary, and suitable precautions are taken to prevent danger.

To fulfil your statutory duty of care on a commercial site, your safe systems of work must strictly include:

• Pre-Site Engineering Surveys: Walking boundaries and cross-referencing DNO maps before any plant or equipment is unpacked.
• The Use of Safety Zones: Deploying physical goalposts and non-conductive barriers to restrict high-reaching equipment from encroaching on live exclusion paths.
• Rigorous Equipment Training: Ensuring field operatives understand maximum extension limits and safe clearance distances for lighting rigs, ladders, and delivery vehicles.

Protecting Your Team and Infrastructure

This incident demonstrates that a single oversight in planning can lead to life-altering human suffering and devastating legal and financial penalties. Safety is not achieved by luck; it is built through strict engineering protocols.

If you manage commercial facilities or lead site maintenance packages, ensure your safe systems of work are fully robust before ground is broken or plant is deployed.
