An Edinburgh food firm has been fined after a worker seriously injured his hand on an unguarded dough mixer.

Edinburgh Sheriff Court heard that Joseph Burnett had been employed as a factory assistant for almost four months and helped to sort ingredients, make Chinese dumplings to order and package products.

On the day of the incident he was working on an industrial-sized dough mixer, into which ingredients and water are placed. Paddles then rotate to mix the ingredients into dough.

The shutter on top of the machine when in the closed position still left a gap of approximately eight centimetres. There was also no interlocking on the dough mixer machine which would have cut the power to the dangerous rotating parts when the metal shutter was lifted.

Mr Burnett was concerned the dough was too wet and began to add extra flour into the mixer by hand. He suddenly felt his hand and arm being pulled into the drum of the machine, with his arm going in past the elbow of his right arm before he managed to pull himself free and alert others to what had happened.

Mr Burnett suffered two factures in his fingers and ripped tendons in his index and middle fingers. He had to undergo surgery, required 30-40 stitches, his arm was in a plaster cast for eight weeks and he needed physiotherapy to help restore movement in his fingers. He still has limited movement in his index finger.

Following the incident, an investigation by the Health and Safety Executive (HSE) found that the company had failed to carry out a risk assessment for the operation.

The investigation also found that the company had failed to provide a safe system of work or sufficient information, instruction, training and supervision in relation to the use of the dough mixer machine.
