Fire rating of exit door
Fire rating of exit door
(OP)
How do I find what fire rating is required for a stair exit door to the exterior from a public library? I checked the Ontario building code but so far have not found it (except for a statement saying not less than 45 minutes for exit doors, and not lsss than required in 3.2.2, but I don't see exit doors sepcifically mentioned in 3.2.2), although it must be there somewhere.

I will also see if I can contact an architect.
