(C) Where possible, the ladder shall be so located as to provide a clearance of twenty-four inches (24") outward on the climbing side. Where the size of the cellar or necessary placement of equipment does not permit the full twenty-four inches (24") clearance, the ladder shall be located so as to provide the maximum clearance available, and in no case less than fourteen inches (14").

Where the height of the substructure and necessary placement of equipment does not permit a full six and one-half feet (6 1/2') vertical height above ground level, the maximum height available shall be used, but in no case shall it be less than four feet (4') above the ground level.
Beams of the substructure and pipe lines may be permitted horizontally across the passageway at ground level if an unobstructed vertical clearance of at least three feet (3') above such beams or pipe lines is maintained. Beams of the substructure or pipe lines shall not be permitted longitudinally within the two feet (2') width of the passageway.
