Two companies have been fined after a worker received serious electrical burns during demolition work.
The Magistrates’ Court in Chelmsford heard how in April 2017 two demolition workers employed by a sub-contractor (R B Haigh & Sons) were removing electrical distribution equipment from a switchgear room at the former Molecular Products site in Thaxted, Essex. Mr AB had been told by the principal contractor (A J Wadhams & Co Ltd) that the electrical equipment had been isolated. In an effort to reassure his colleague that it was safe he threw a crowbar at the 400V AC equipment. This came into contact with live exposed wires, causing a flashover and temperatures of several thousand degrees, followed by a subsequent fire. As a result, AB suffered serious burn injuries and was immediately hospitalised.
An investigation by the HSE found that the task being undertaken had not been properly planned and suitable control measures were not implemented to ensure the isolation of the power supply. The principal contractor failed to follow the clear procedures outlined in their risk assessments and method statements, which identified all equipment must be treated as live unless written authorisation proved otherwise.
Russell Haigh and Stuart Haigh (Partners of R B Haighs & Sons) of Thaxted, Essex, pleaded guilty to breaching Regulation 3(1) of the Electricity at Work Regulations 1989 and have been fined £80,000 and ordered to pay costs of £3882.65. AJ Wadhams & Co Limited trading as Wadham Homes of Charterhouse Street, London, pleaded guilty to breaching Section 3(1) of the Health and Safety at Work etc Act 1974, and have been fined £80,000 and ordered to pay costs of £3816.60.
After the hearing HSE inspector Adam Hills said
This incident has had a significant impact on AB’s life and the injuries could so very easily have been fatal. Had the companies followed the control measures outlined in their respective risk assessments, then this incident would not have occurred. Never assume that an electrical supply is disconnected. Always check with the Distribution Network Operator or a qualified electrician to obtain written proof of isolation before commencing work.
