Chelmsford Magistrates’ Court heard that in February 2016 an employee was excavating the ground at a site on Spare Lease Hill in Loughton, Essex.

He struck an electrical cable and was set on fire. He received significant burns to his lower body, causing him to be hospitalised for one month and unable to work for six weeks.

An HSE investigation found the company failed to adequately plan, manage and monitor the construction work; failed to obtain drawings from the utility company detailing the position of underground cables, and did not re-scan the affected ground to a sufficient depth while excavation work was ongoing.

Both the injured person, and the employee responsible for scanning the ground did not receive training for their tasks, despite this being detailed in the company’s risk assessments and method statements.

Mason Construction (London) Limited of Hertford, pleaded guilty to breaching CDM Regulations and was fined £25,000 and ordered to pay costs of £3979.68.

After the hearing HSE inspector David King said: “The contractor’s injuries were very serious, and he could have easily been killed.

“This injury would have been prevented if the company had planned and implemented safe methods of working, and provided the necessary information and training to its workers.”
