Scaffolder Colin Dell, 62, suffered life-changing injuries while working near the main cooling water discharge valves at a site in Kent on 13 June 2022.
Dell was conducting scaffolding work when a hydraulic actuator, or ram, was not in place, leaving a heavy counterweight unsupported. While measuring the area, the counterweight suddenly fell from a cooling water pump, striking his hand and foot and trapping him. He sustained severe injuries, including broken and amputated toes on his left foot, and required four days of hospital treatment.
The injuries have left Dell unable to return to work as a scaffolder and he has since been diagnosed with post-traumatic stress disorder.
A prosecution by the Office for Nuclear Regulation (ONR) revealed significant safety failings by EDF, the site operator, and Trillium Flow Services Ltd, the contractor responsible for maintenance. Both companies pleaded guilty to safety offences at Folkestone Magistrates’ Court.
Fines and Outcome
- EDF was fined £533,333.
- Trillium Flow Services Ltd received a £100,000 fine.
- Both companies were ordered to pay £15,034 each in prosecution costs.
District Judge Stephen Leake highlighted the companies’ failure to protect workers from a known risk, emphasizing the avoidable nature of the accident.
ONR’s Findings
Dan Hasted, ONR’s Director of Regulation – Operating Facilities Directorate, commented:
“This accident was wholly avoidable. Nobody should go to work and not come home in a fit and healthy state. Our investigation found that EDF and Trillium Flow Services Ltd failed to follow the correct sequence for re-fitting the valve, leading to Mr. Dell’s injuries. There were multiple missed opportunities to prevent this incident.”
About the Site
The incident occurred at Dungeness B, which ceased power generation in June 2021 and is now in the defueling phase. The site’s cooling system features four main pumps, each equipped with a discharge valve.
This case underscores the importance of adhering to safety protocols to prevent avoidable workplace injuries.
