Wash. Admin. Code § 296-800-25015 - Provide handrails and stair railings

Exemption: Vehicle service pit stairways are exempt from the rules for stairway railing and guards, if they would prevent a vehicle from moving into a position over the pit.

(a) At least one handrail, preferably on your right side as you go down the stairs, if both sides are enclosed; or
(b) At least one stair railing on the open side, if one side is open; or
(c) One stair railing on each side, if both sides are open.
