Wardrop had already admitted failing to ensure the health and safety of its employees at an earlier meeting, but at last week’s court appearance was found to have “put profit before workers”.

The court heard that the machine did not have the correct guards and that workers had not been given full instructions on its use.

“I have come to the overwhelming conclusion that the company put profit before workers,” said Norwich Crown Court recorder Guy Ayers.

“The machinery was significantly dangerous to the people who were working them.”

Wardrop was issued with a £25,000 fine plus ordered to pay £10,000 in costs by the court for its part in the accident, although it added in mitigation that safety procedures at the plant has been improved.
