Doors in a fire wall

[Mr Burns]

Hi Everyone,

I have a couple of question regarding fire doors in fire walls in comercial buildings.

1) I was supplied a compartmentation strategy floor plan for a fire door audit and was told that it is ok to put a FD30 in a 60 min fire wall?  is this correct?

2) does every door in a fire wall need to be a fire door? i.e toilet doors and office doors? as well as high risk rooms/areas?

many thanks

1. Yes fire doors can be half the fire resistance of the wall, check out ADB, compartmentation.

2. Depends on the circumstances is it MoE of fire separation.

Hi Tom,

Thanks very much for your reply,

yes the toilet doors are in a corridor/ enclosed lobby area oppisite a stairwell door used for a fire escape, so in this case the WCs need to be a fire door I presume?

Thanks

Mr B
