A new Code item requires a minimum distance between two exterior discharges of exit stairs from the same floor area [3.4.2.3.(4)].
My question is: should this also be applied to exterior exit doors if there is no stairs? For example, a main floor suite that has an exterior exit door, but the other egress required from the suite is then to an exit lobby, which discharges directly beside the suite exterior exit door.
I am dealing with a system that is used to protect storage tanks at one of our industrial facilities, this system is an outdoor deluge
NBC 2015 Div B-9.8.9.5. Treads 1) Stair treads of lumber, plywood or O-2 grade OSB within dwelling units shall be not less than 25 mm
My question is: Is there ever a time that access needs to be provided around an entire building?
