When conditions are such that neither a walkway nor a straight ladder can be used, a Jacob's ladder meeting the requirements of subsection (4) of this section may be used.
(c) The means of access shall meet the requirements of subsection (1)(i), (j), and (k) of this section.
(4) Jacob's ladders.
(a) Jacob's ladders shall be of the double rung or flat tread type. They shall be well maintained and properly secured.
