My boss has recently taken over a pub and wants to use a fire door that leads to the externals of the building as a normal entrance for customers but in the same instance the door is located right where he is also going to put live bands which will block some of this door way. Someone has told him this is illegal and I'm wondering if you could give me a little advice on it please.

Best regards
Sarah

Someone is correct you need full width of the door with no obstructions. Check out https://www.gov.uk/government/publications/fire-safety-risk-assessment-offices-and-shops
