[Fire door hinges leaking]

Our fire doors are around 5 years old now and whilst doing the annual inspection, most of the hinges are now leaking oil. Am i best to replace these? Or is this still deemed acceptable? 

 

Thanks

[Fire door gap]

Hello All!

I have recently taken over the fire safety within the Company I am working for. They have never done any fire door checks. 

When undertaking this, I found that 7/10 of the doors on the main escape route had more than a 4mm gap between the door leaf and frame (top and sides). What is the best solution to correct this? Can i just add strips of wood the door frames to correct this gap? Is this solution accepted?

Thanks in advance.
