Two people have been taken to hospital after a fire broke out at BAE Systems’ Barrow-in-Furness shipyard in Cumbria, police said.
Cumbria Constabulary said the fire at the nuclear submarine shipyard broke out at about 12.45am and remains ongoing in an update at 7am.
Police said there is “no nuclear risk”, but two people were taken to hospital for suspected smoke inhalation.
The facility is home to Britain’s Astute-class submarines and Dreadnought programme.
Cumbria Fire and Rescue are likely to have appliances on site for much of the day today.
A statement said: “At this time there are no other casualties and everyone else have been evacuated from the Devonshire Dock Hall and are accounted for.”
The force advised people living nearby to “remain indoors whilst emergency services respond to the incident and keep doors and windows closed”.
A road closure is in place on Michaelson Bridge.
BAE Systems has been contacted for comment.
