The London Fire Brigade has served an enforcement notice on London Underground, citing eight breaches of fire safety rules at London Bridge Tube Station.

Details of the enforcement notice – which was issued on 10 April – were recently made public on the fire brigade website.

London Underground has until 5 June to comply with the remedial measures set out by the fire brigade, and an internal investigation has been launched.

The eight breaches of legislation identified by the fire brigade include "failure to provide a suitable method of giving warning in case of fire", "failure to provide and/or maintain adequate and clearly indicated emergency routes and exits that lead to a place of safety" and failure to ensure that the premises and any facilities, equipment and devices for use by or protection of fire-fighters are maintained in an efficient state, in effective working order and in good repair".

Fire safety on the Tube was tightened up after the 1987 fire at King's Cross St Pancras in which 31 people died.

The SE1 website approached Transport for London for comment last week but no response was received by the time of publication.

Update Wednesday 4pm – A TfL spokesman told the SE1 website: "Safety is always our top priority, and we work closely with London Fire Brigade to ensure that our stations are safe for our customers and staff.

"We have met with them to discuss the issues that they identified and have taken urgent steps to address all of them."
