Hi,
I work at a dental surgery and we were previously told by a fire officer that a ground floor window was a secondary fire exit. All fire exit doors already have the appropriate signage. Is it necessary to use such signage and lighting on all accessible ground floor windows which may be considered secondary fire exits?
I would be grateful for your advice.
Many Thanks,
Niamh

Who is this Fire Officer is he/she from the local Fire and Rescue Service and were they conducting a fire risk audit. If anything requires attention they should have sent you report on what requires attention.

Is your Fire Risk Assessment (FRA) up to date, if so you would have informed if any windows are required for alternative means of escape and if signs are required.

Check out the appropriate guide https://www.gov.uk/government/publications/fire-safety-risk-assessment-healthcare-premises or contact the person that conducted your FRA.
