Firms have been warned that they face prosecution and injury compensation claims if they put their employees at risk of work injury.
It follows a GBP 6,000 fine for Cheshire-based company Eazyfone after it allowed a worker to fit a CCTV bracket to the side of a building, while raised more than two metres on a pallet on the forks of a forklift truck.
The incident was observed by two Health and Safety Executive (HSE) inspectors who were passing the company’s offices in March.
HSE inspector Deborah Walker said that although nobody was hurt this time, it could potentially have resulted in serious injury or death.
She added: "The method that was used was badly thought out and unsafe.
"This case should remind employers of the importance of working safely at height."
It follows an incident in a Wales garage in which poor safety procedures led a young child to be injured after falling six feet from a ramp.
