A safety review of Peterborough City Hospital has uncovered potential fire risks at the Bretton site.
Bosses at the hospital have made staff and patients aware of the need for extra vigilance around fire safety following a number of issues that were found in a fire safety standards review.
A review of the fire evacuation procedure is now taking place.
Stephen Graves, Chief Executive at Peterborough and Stamford Hospitals NHS Foundation Trust, said: “Following a review of the fire safety standards to which our hospital has been built, we have learned of some potential issues with the infrastructure.
“The scale of these issues is not yet clear, however we have immediately discussed them with Progress Health, the organisation which has responsibility for maintaining the City Hospital building, who are treating the matter with the utmost urgency and have commenced an independent study of the building. We, together with Progress Health, are working to investigate and resolve any potential issues.
“As a precaution we have notified Cambridgeshire Fire and Rescue Service and have taken the decision to review our fire evacuation procedure. We are working with our staff to ensure they are aware of this.
“We can assure our patients, staff and visitors that we will remain vigilant in ensuring fire safety standards are maintained at all times.”
