Rooftop Work Spaces (§ 2.1) Q – How do I mark the egress path from enclosed spaces on the roof that are accessible only from the exterior portions of the roof?
A – The Department does not consider the doors that lead into the stairs from the roofs as “doors opening to exits” per § 2.1 if the only occupancy on the roof is mechanical equipment rooms, elevator machine rooms, etc. However, if the roof is utilized for recreation, assemblies, offices in a penthouse, etc., then we would consider those doors as “doors opening to exits” and we would require a UV-rated sign per § 2.1. Note that enclosed cellar spaces with only mechanical spaces are treated differently – in the cellars, all exits and doors leading to exits must be marked per RS 6-1.
