Paul Osmond, of Hele, Exeter, broke his right arm and injured his left shoulder in the incident at a warehouse in Bancombe Court, Martock, on 31 January this year. He fell 4.5 metres onto a concrete floor after stepping onto the skylight.
The incident was investigated by the Health and Safety Executive (HSE), which prosecuted Philip Saunders Building Contractors at Yeovil Magistrates’ Court.
The court heard that Mr Osmond and a fellow workman were tasked with installing a new roof over an existing tin one.
No mention had been made of the fragile skylights before the work began and no arrangements had been made to install netting to lessen the impact of any falls.
When Mr Osmond stepped onto the skylight it gave way, sending him crashing to the floor below. His arm required surgery and was in plaster for six weeks, rendering him unable to work.
HSE’s investigation found no safe system for covering the skylights had been shown to Mr Osmond or his colleague, such as placing netting or scaffolding underneath to prevent falls.
Philip Saunders Contractors Ltd, of Tiverton, which is now in liquidation, was fined £12,500 and ordered to pay £2,850 in costs after pleading not guilty breaching the Work at Height Regulations 2005.
HSE inspector James Lucas, speaking after the hearing, said:“Although Mr Osmond’s injuries have caused him a great deal of pain and discomfort, he was fortunate his injuries were not more serious or even fatal.
“This incident could easily have been prevented if the job had been planned properly and safety netting or scaffolding installed.
“Falls from height are the biggest cause of workplace deaths and it’s crucial that employers make sure work sufficient measures are put in place to protect staff from the risks. There is no excuse for employers failing to safeguard workers who have to work at height.”
