A Worcestershire engineering firm has been fined £30,000 after a worker lost both of his legs in a factory explosion.
Filtration Service Engineering Ltd was also ordered to pay costs of £15,325 after pleading guilty at court.
51-year-old Clive Dainty, from Kidderminster, was working at the company as a 335-litre vessel which was being pressure tested, exploded.
Health and Safety Executive investigators found the quality of the welding on the vessel could have been tested by simply filling it with water, instead of compressed air.
Mr Dainty was in hospital for several months afterwards and had to have both legs amputated.
He also suffered head injuries and now has problems moving his arms, which were repaired using metal plates.
