Daniel Timbers, 29, of Dereham Road, Costessey, and Barry Joy, 56, of Spencer Street, Norwich, died after an explosion at Harford Attachments on the Vulcan Road Industrial Estate, near Hellesdon, on July 13, 2015.

Opening the men's inquest a week later, senior coroner Jacqueline Lake said both men's medical cause of death was the effects of fire and inhalation of fumes of combustion pending further investigation.

She said: 'Both men were working in the premises when an explosion occurred.

'Both men were located by fire officers and their death was confirmed at the scene.'

Mr Timbers worked as a production operative and Mr Joy was a paint sprayer.

Detectives from the Norfolk and Suffolk Major Investigation Team, with Norfolk Fire and Rescue Service and the Health and Safety Executive (HSE), launched an investigation following the deaths.

A spokesman for the HSE said the matter is still being investigated and any decision over whether any possible offences were committed would have to wait until after an inquest into the deaths.

He said: 'Following a police investigation, the Health and Safety Executive (HSE) now has primacy for this matter which is still under investigation pending the outcome of the inquest, listed for two weeks from 10 July. On conclusion of the inquest, HSE will review all evidence and consider possible offences.'

As reported last year, Norfolk police had previously contacted the Crown Prosecution Service (CPS) about the case and were waiting to hear back from them to see if criminal charges were likely.

In the days following the deaths of Mr Joy and Mr Timbers fellow workers described frantic and courageous efforts to save the two men.
