Heathrow Airport has been fined £10,000 after a contractor suffered “life-changing injuries” when he fell into a 2.2 m deep gully while working on the roof at Terminal 1 in March 2007.
City of London Magistrates Court heard that the maintenance worker was walking from one part of the terminal roof to another.
It was told there was no edge protection around the gully and local lighting was not working.
The Health and Safety Executive said: “The injured worker suffered life changing injuries and is now unable to do the work that he used to do.”
Heathrow Airport pleaded guilty to breaching the Health and Safety at Work etc Act and was ordered to pay costs of £3,130 in addition to the fine.
