(2)   A door that forms a part of a means of egress shall swing in the direction of egress for occupancies of 13 or more.

(3)     In   new  construction,  additions,  conversions,  renovations,  and remodeling, an exit door that is required to swing out shall swing directly onto a floor-level landing that is at least as deep as the swing of the door before the start of any steps or ramps to grade.

(6)   In new and existing buildings, only ambulatory campers shall be permitted above or below the first or ground floor, except where the floor above or below the first floor provides all required exiting at grade without using stairways.

(7)   In new construction, additions, conversions, or remodeling, where stairs or steps are used in any part of the required means of egress for camper-occupied areas, they shall have maximum risers of 7 inches and minimum treads of 11 inches.
