Design requirements for mobile ladder stand platforms.

You must ensure:
(1) The steps of mobile ladder stand platforms meet the requirements of WAC 296-876-91010(1). When the employer demonstrates that the requirement is not feasible, steeper slopes or vertical rung ladders may be used, provided the units are stabilized to prevent overturning.
(2) Mobile ladder stand platforms with a platform height of four to ten feet (1.2 m to 3 m) have, in the platform area, handrails with a vertical height of at least thirty-six inches (91 cm) and midrails.
(3) All ladder stand platforms with a platform height above ten feet (3 m) have guardrails and toeboards on the exposed sides and ends of the platform.
(4) Removable gates or nonrigid members, such as chains, are only permitted to be used on mobile ladder stand platforms, instead of handrails and guardrails, in special-use applications.
