I am looking confirm my understanding on the requirement for fire doors in corridors. The scenario is a long corridor (circa 30 metres) in a primary school with a fire resistant door at each end. Is there a requirement to provide and additional door in between?

Having raised this and then found the answer could you share it?
The forum should have rules about this sort of teasing!

They may need to be double swing doors depending on the means of escape.

Don't forget if you create a fire resisting compartment to ensure it is also compartmented above and laterally.

School when built would have been subject to Building Regs approved doc B (Fire Safety ) which from memory is origin of the 30m corridor smoke division doors
