Police today named the four workers who perished in the Bristol sewage plant explosion, including a 16-year-old boy – after the devastated wife of one of the victims revealed her son had been due to work on the same spot.
Avon and Somerset Police said that Luke Wheaton, 16, Michael James, 64, Brian Vickery, 63, and Raymond White, 57, were all killed by a blast thought to have been caused by an exploding chemical tank.
It is understood that Mr James was a contractor working at the site, while Mr Vickery and Mr White were employees of Wessex Water and Luke, a former pupil of Bradley Stoke Community School, was an apprentice.
In a statement, the force added that specially trained officers are supporting the victims' families, while investigators will speak to the person who survived the blast and is now recovering from their injuries at home.
Emergency services were called to reports of a large explosion involving one of the chemical tanks at the site at about 11.20am. The blast happened in a silo that held treated biosolids.
Avon and Somerset Police, which declared a major incident, said a cordon at the site was likely to remain in place 'over the coming days' as an investigation is carried out. This is being supported by the Health and Safety Executive (HSE) and a team of chemical and mechanical experts, the force said.
It came as other colleagues of the workers who died at Wessex Water Services Ltd in Avonmouth yesterday were said to be in a 'state of shock' after one was blown 500ft into a lake by the force of the blast.
Bradley Stoke Community School paid tribute to Avonmouth explosion victim Luke, writing on Facebook: 'We were shocked and saddened to hear of the tragic passing of our former student Luke Wheaton yesterday in the Avonmouth tragedy. Our thoughts are with his family and friends at this time.'
North Bristol Rugby Football Club tweeted: 'Such terribly sad news that one of our Colts, Luke Wheaton was tragically lost in the accident in Avonmouth yesterday morning. It's absolutely heartbreaking. All of our love & thoughts to Luke's family, team mates, coaches and everyone else that new him.'
Supt Simon Brickwood of Avon and Somerset Police said: 'I'd like to extend my heartfelt sympathies to the families of those involved in yesterday's tragic incident. An investigation has been launched into the causes of the explosion, with the support of partner agencies and the Health and Safety Executive.'
Giles Hyder, HSE's head of operations in the South West said: 'We send our deepest condolences to the families of those who tragically died. It is important a joint investigation is carried out. We will provide specialist support to what is likely to be a complex investigation under the command of the police.'
Wessex Water CEO Colin Skellett said: 'We are all absolutely devastated by what has happened. Our hearts go out to the family, friends and colleagues of those who lost their lives during the tragic event on Thursday.

Today Brian Vickery's wife Jane said her husband worked at Wessex Water for 42 years. She also revealed that she could have been robbed of two members of her family, if not for the fact their son had been on a holiday day.
Choking back emotion, she said: 'Brian had worked there for 42 years. Our son works there but had a day off yesterday. If he had been there he'd be dead too. We didn't hear anything for about five hours after it happened.'
Trade union Unite Unite's regional secretary for the south west, Steve Preddy, said earlier today: 'We can confirm that Unite has three members working at Wessex Water Services Ltd in Avonmouth. We have contacted them and they are, thankfully, uninjured, although in a state of shock.
'Unite will be giving our members maximum support in the days and weeks ahead. Unite the union would wish to extend its deepest sympathy to the families of those employees who have lost their lives and as well as those injured in the explosion – our thoughts and solidarity are with all those affected by this tragic event.'
The chemical tanker blew up at around 11am yesterday. Witnesses were struck by the magnitude of the explosion, which shook nearby buildings and blew a body into a lake 500ft away.
Sean Nolan said: 'It was quite short-lived, I'd say about two or three seconds. Sort of a boom and echo and then it just went quiet. That was it. There was no smoke, there was no after-effects of it.' Keiran Jenkins, who was in a nearby warehouse, said he and colleagues stood rooted to the spot in shock as the walls trembled.
Emergency service crews launched a major operation involving two search and rescue dogs and six fire crews after the blast on the industrial estate off Kings Weston Lane.
Chief Inspector Mark Runacres of Avon and Somerset Police told a press conference yesterday night: 'The fire service led the rescue operation but sadly, despite the best efforts of all those involved, we can confirm there have been four fatalities. This includes three employees of Wessex Water and one contractor.
