Ayrshire-based manufacturer Hillhouse Precast Concrete has been fined £10,000 for safety failings after worker Christopher Fay became entangled in a rolling machine used to flatten concrete in a mould.
The worker's glove became caught in a metal D-ring connecting the roller to the handle of the machine drawing his arm into the roller as it turned and breaking it in two places.
Mr Fay needed two plates surgically inserted in his arm and physiotherapy treatment. He no longer has full strength in his right arm leaving him unable to lift heavy loads and has been left with scarring. He has since returned to work with a different company.
Kilmarnock Sheriff Court was told that around a month before the incident took place on 18 January 2010 at the company's factory in Beith, the machine's handle was leaking hydraulic fluid and was replaced.
The original handle had a 'hold to run' mechanism fitted which prevented workers being exposed to the risk of the machine starting automatically, and therefore unexpectedly, if it was turned on remotely. However, the new switch did not have this safety feature and so was capable of being left in the 'on' position. No one had noticed the difference.
On the day of the incident the machine was restarted remotely by an employee who was unable to see Mr Fay and other staff working at the roller. Mr Fay was standing close to the machine and his glove was caught in the machinery.
HSE Inspector Mark Carroll said that while the offence came about through an inadvertent mistake rather than any deliberate failure to comply with standards, not replacing the control switch with a similar 'hold to run' device, removed the only safety feature to protect workers from the concrete roller starting unexpectedly.
"Hillhouse Precast Concrete Ltd has introduced measures and bought new equipment to avoid a repeat of the incident, but it could have been prevented by better consideration of how the repair work affected the safe operation of the roller," he added.
