Rule 537.
(1) In
				  existing and small facilities, all stairways and other vertical openings shall
				  be enclosed with materials equal in fire resistance to the standard partition
				  construction of the building, if such partition construction is at least
				  standard lath and plaster. There shall be at least a 1 3/4-inch solid-core wood
				  door that has self-closing and latching hardware which is installed so that
				  there is effective fire and smoke separation between floors or, alternatively,
				  each sleeping room on the second floor shall be equipped with at least a 1
				  3/4-inch solid-core wood door with latching hardware.
(2) In all new and converted large and secure
				  facilities, stairways shall be enclosed with materials that have at least the
				  fire-resistance rating specified by the national fire protection association
				  pamphlet no. 220, 1979, for the type of construction. All other vertical
				  openings through floors shall be fire-stopped with like materials.
(3) If a facility has less than 3 levels, if
				  each level exits at grade, and if elevations between levels are not more than 4
				  feet, the building shall be considered to be 1 story and enclosures shall not
				  be required between levels.
(4) In
				  all new and converted facilities, stairs shall have treads and risers of
				  uniform width and height, with treads that are not less than 9 1/2 inches deep,
				  exclusive of nosing, and risers that are not more than 7 3/4 inches in
				  height.
(5) Stairs in new,
				  remodeled, and converted facilities shall change direction by use of an
				  intermediate landing and not by a variance in the width of the treads. A sturdy
				  and securely fastened handrail that is located between 30 and 34 inches,
				  measured vertically, above the nose of the treads shall be provided.
(6) Stairs in existing facilities that are
				  approved before these rules take effect shall continue to be approved until the
				  portion of the building that encompasses the stairs is remodeled.
(7) An outside stairway or fire escape that
				  is used as part of an approved means of egress shall be protected against fire
				  in the building by blank or closed walls directly under such stairway and for a
				  distance of 6 feet in all directions. Windows are permitted within this area if
				  they consist of wire glass set in unopenable frames.
(8) In newly constructed small facilities,
				  halls, corridors, aisles, and stairs that are used as part of a means of egress
				  shall be not less than 44 inches wide and shall be not less than 36 inches wide
				  in converted small facilities, except as required by
				  R
				  400.10535(10).
(9) In newly constructed and converted large
				  and secure facilities, halls, corridors, and aisles that are used as part of a
				  means of egress shall be not less than 5 feet wide and 90 inches high and
				  stairs that are used as part of an exit shall be not less than 4 feet
				  wide.
