Shipbuilders and Royal Navy personnel working on the UK’s newest Astute-class submarine were taken to hospital on Saturday after a carbon monoxide leak was discovered inside the submarine.
According to North West Evening Mail, the evacuation from future HMAS Audacious started when sensors detected high carbon monoxide levels.
Some 18 workers were taken to hospital following the incident as a precaution and returned to work in the afternoon, according to the report.
HMAS Audacious, built by BAE Systems in Barrow in Furness, was launched in April this year and is expected to start sea trials in 2018.
The 7,400 tonne, 97-metre long, nuclear-powered submarine is the fourth of overall seven boats that will be built for the Royal Navy
