Emergency services were called to the site at 12.30pm on Wednesday, November 9, after reports of a gas leak at the brewery on Bridge Street.
Northamptonshire Police have confirmed that 11 workers from the site as well as 11 members of the emergency services were taken to hospital. Remaining staff from the factory were evacuated.
The incident was attended by Northamptonshire Fire and Rescue, which sent nine fire engines to the scene, as well as two specialist appliances.
Carlsberg UK chief executive Julian Momen said he was deeply saddened by the tragic incident and subsequent fatality.
“Our immediate thoughts are with the individual’s family, friends and colleagues at this very difficult time and we will support them in every way we can,” said Momen.
“Our further thoughts and support are with our colleagues and members of the emergency services who are being treated in hospital.”
It was unclear what had caused the gas leak, but Momen said Carlsberg was working with the authorities to investigate how the incident occurred.
“We will be in a position to say more once a full investigation has been concluded,” added Momen.
Leak was confined
The leak was confined to the Carlsberg UK site and the emergency services did not believe there was a wider risk to members of public.
Production at the brewery has been stopped while the investigation takes place. The cause of death for the worker is currently not known.
Meanwhile, the death of a Sainsburys worker was under investigation by Merseyside council, after the man was involved in a forklift truck accident.
Police were called to the St Helens distribution centre on September 29, where officers found paramedics treating the injured man for serious head injuries. He was later pronounced dead at the scene.
