Police investigating the Bosley mill explosion have spoken to the owners of the company and employees that worked there in a bid to discover the cause of the blast.
Describing the site as a "potential crime scene", Cheshire Police said they were attempting to gain information on the history of Wood Treatment Limited, which operated the wood flour mill.
Families of the four people missing following the disaster will make a visit facilitated by emergency services tomorrow, police said.
The first body recovered from the Bosley mill fire wreckage is believed to be that of William Barks, Cheshire Police has said.
The 51-year-old, who had been married for 31 years, was born and bred in Leek, Staffordshire.
Police said the body, recovered on Sunday, did not belong to any of the other three people missing following the blast.
Identifications on a second recovered body are ongoing, it was added.
Earlier his brother told ITV News Barks was a "hero" who was "so knowledgable" and "well-respected by everybody".
Kelvin Barks also said the fire at the wood mill had been a "disaster waiting to happen", alleging that the owners had failed to buy parts for a faulty machine despite "relentless" requests.
Kelvin Barks told ITV News his brother William, who was an engineer at the factory, tried to get a new job but 'had bills to pay'.Read the full story ›
A Bosley mill worker says he was given no safety training whatsoever before he started working there just a week ago.
Scott Cole told ITV News: "There was no safety training at all.
"I went in there to have a brief interview, three minutes, and he told me to start on Monday.
"He didn't tell me how to work the machines, nothing. I just learnt myself. I asked for a protection mask. Three days in, and I still didn't get one."
The Health and Safety Executive is now investigating the causes of the explosion.
The mill owners have said they will cooperate with the process but families of four workers still missing said they were "disgusted" they had not been in touch since the incident happened.
Dorothy Bailey, Derek Moore, Jason Shingler and William Barks have been missing since Friday's explosions.Read the full story ›
It will take some time to identify two bodies found at Bosley mill following two explosions last week, Cheshire Fire Service has said.
Chief Fire Officer Paul Hancock said the second body was found six metres below the first body, which they recovered on Sunday.
"The search and rescue team are absolutely determined to find the remaining two people who are still missing," he told a news conference.
"They are now working inside the collapsed structure in what are even more demanding conditions.
"Lots of pockets where small fires are still burning. We have removed hundreds of tonnes of rubble.The recovery is very difficult and very challenging."
He added he was confident the two missing people were in the same vicinity as the two bodies they had found already.
Staff at the Bosley mill where two explosions occurred last week have claimed they had no induction or safety training.
The Health and Safety Executive said they still do not know what caused the blast but staff training would form part of their investigation into the incident.
Cheshire Fire Service confirmed two bodies had now been found in the rubble but two people remain missing.
Chief Fire Officer Paul Hancock said "there was always hope" they would find them alive.
"But we are realistically now starting to move into a search and recovery phase," he added.
Cheshire Fire service have released this footage of the scene at Bosley mill after two explosions sparked a massive fire last week.
The video shows just how damage was caused in the blaze which started on Friday.
Two bodies have since been found and a further two people remain missing.
A second body has been recovered in the Bosley mill search, Cheshire Police have confirmed.
Fire and rescue teams have been working non-stop to find William Barks, 51, Dorothy Bailey, 62, Jason Shingler, 38, and Derek Moore, 62, since Friday's blast at the Wood Flour Mills in Tunstall Road, Bosley.
No formal identification has taken place on the body found today.
The brother of a missing Bosley mill worker has told ITV News of his anger at what he called the lack of support or sympathy from the mill's owners since the devastating explosion.
Kelvin Barks, the brother of William, said: "My brother worked at that mill for 12 years. He's been missing for over three days now; In all that time nobody at the company has contacted us at all - no offer of support or sympathy or help."
