What 29 CFR 1910.22 requires (plain English)
29 CFR 1910.22 sets the general requirements for walking-working surfaces in general industry: the floors, aisles, platforms, and passageways workers use every day. It is the foundation of Subpart D, and its rules are deceptively simple: keep surfaces clean, orderly, and in good condition so that slip, trip, and fall hazards do not develop.
The standard requires that all places of employment, passageways, storerooms, service rooms, and walking-working surfaces be kept in a clean, orderly, and sanitary condition; that surfaces be maintained free of hazards such as sharp or protruding objects, loose boards, corrosion, leaks, spills, snow, and ice; and that they be maintained with the structural integrity to support the maximum intended loads. Where wet processes are used, drainage and dry standing places are required.
1910.22 underpins the rest of Subpart D: ladders (1910.23), stairways (1910.25), and the duty and criteria for fall protection (1910.28 and 1910.29). It reflects that the most common workplace injuries come not from dramatic hazards but from ordinary surfaces that were allowed to become wet, cluttered, or broken.
