An engineer was testing a sprinkler system at a site in Hemel Hempstead. In the course of his investigations he climbed onto an internal roof using an extension ladder. The ladder slipped and he fell 3 metres into the gap between the internal roof and the external wall. Once safely extracted he received treatment for a head injury, fractured vertebrae and soft tissue damage. The severity of his injuries and the time it took for his extraction caused him significant blood loss.
The HSE found that the arrangements for working in the internal roof were inadequate and laid the blame with the principal contractor, Modus Workspace Ltd. The company were found guilty of breaching section 3(1) of the Health & Safety at Work etc. Act 1974 and fined £1.1 million. It was also ordered to pay costs of £68,116.
