A Dartford-based engineering firm has been prosecuted for safety failings after a teenage apprentice fell from a ladder as he received an electric shock from badly wired equipment.

The apprentice engineer, just 17 at the time of the incident on 15 June 2012, fell nearly three metres to the floor as he recoiled from an instant bolt of electricity. He suffered a herniated disc and numbness in his lower back, but has since returned to work.

The incident was investigated by the Health and Safety Executive (HSE) which prosecuted Kenard Engineering Company Ltd at Dartford Magistrates' Court.


Magistrates heard that the apprentice, who doesn't wish to be named, was helping a maintenance worker to move a pillar-mounted crane. When it was in place and the crane wired-up, he climbed a ladder to plug in CNC computer equipment to the cable tray socket.

When the young worker's hand touched the cable tray on top of the pillar, the tray 'earthed' him. At the same time, the pillar he was holding on to for balance became live as a wire had been connected wrongly into the earth.

HSE found that Kenard Engineering had failed to ensure their working systems were safe by allowing someone without the proper competence and experience to wire up the crane. The firm had an electrical specialist moving and installing the CNC machines but it was customary for employees to move and wire in the cranes.

Kenard Engineering Company Ltd, of Green Road, Dartford, Kent, was fined £10,000 and told to pay £1,981 in costs after admitting breaching Regulation 4(1) of the Electricity at Work Regulations 1989.
