(1) You must guard open-sided floors and platforms.
(a) Guard open-sided floors and platforms four feet or more above adjacent floor or ground level by a railing. The entrance to a ramp, stairway, or fixed ladder does not need a railing.
(b) Guard open-sided floors, walkways and platforms above or adjacent to dangerous equipment, pickling or galvanizing tanks, degreasing units, and other similar hazards, regardless of height with a railing and toeboard.
(2) You must make sure tools and loose materials are not left on overhead platforms and scaffolds.
Note: | • Where the guarding rules above do not apply because employees exposure to falls is infrequent (not on a predictable and regular basis), you must comply with the Personal Protective Equipment (PPE) rules (WAC 296-800-160) or other effective fall protection must be provided. |
• You can find the minimum requirements for standard railings of various types of construction in WAC 296-24-75011. |
