Two companies are facing prosecution over an oil refinery explosion in south Wales seven years ago in which four maintenace workers were killed.
Valero Energy UK and B&A Contracts have been told by the Health and Safety Executive that they face charges under the Health and Safety at Work Act following the Pembroke Refinery incident in June 2011.
Workers Robert Broome, Andrew Jenkins, Julie Jones and Dennis Riley died after a 730 cu m storage tank exploded and caused a fire in one of the refinery’s buildings. Andrew Phillips suffered major injuries.
HSE deputy director of field operations Jane Lassey said: “Following a painstaking and extremely thorough investigation, much of which was conducted jointly with Dyfed Powys Police, we have concluded that there is sufficient evidence to bring criminal charges.”
At the time the refinery (pictured) was owned by Chevron Ltd, but ownership changed to Valero in August 2011. B&A Contracts specialises in industrial cleaning services.
The defendants are due to appear at Haverfordwest Magistrates Court on 24 September.
The Crown Prosecution Service decided in November 2015 that there was insufficient evidence to proceed with corporate manslaughter charges against Valero Energy UK and B&A Contracts.
B&A Contracts declined to comment. Valero UK has been contacted by CN.
