A civils contractor has been fined £250,000 after a self-employed ground worker lost an arm following a disc cutter accident.

Truro Crown Court heard how on 1 June 2017, self-employed ground worker Morgan Prosser, contracted by MJL Contractors Limited, was working to complete ground works at a new building site near Bodmin, Cornwall.

Prosser was using a petrol disc cutter to cut reinforced concrete beams to size when the saw ‘kicked up’ and caused a severe laceration to his arm.

He underwent months of operations following the incident to try to save his arm but it had to be amputated In October 2017, which has had a significant impact on his ability to work and his personal life.

An HSE investigation found that MJL Contractors Limited were responsible for the groundworks at the site, including providing and maintaining the disc cutter.

Prosser had not been sufficiently trained to use the petrol disc cutter and the system of work in use for cutting reinforced concrete beams had not been planned or assessed to ensure the risks were properly controlled.

MJL should have been aware that Prosser had no previous experience of undertaking such a task and this should have been identified and addressed at his induction or at the time the work was allocated to him to complete.

MJL Contractors Limited of Helston in Cornwall, were found guilty of safety breaches and have been fined £250,000 and ordered to pay costs of £100,000.

Speaking after the hearing, HSE inspector Georgina Symons said: “The contractor’s injuries have been life changing. This serious incident could have easily been avoided if basic safeguards had been put in place.”
