Clean, dry, and free of hazards
1910.22(a) sets three plain requirements:
- (a)(1) — surfaces, passageways, storerooms, and service rooms kept clean, orderly, and sanitary.
- (a)(2) — floors kept clean and, to the extent feasible, dry. Where wet processes are used, keep drainage working and provide dry standing places like platforms or mats.
- (a)(3) — surfaces kept free of hazards such as sharp or protruding objects, loose boards, corrosion, leaks, spills, snow, and ice.
That last list is basically the whole slips-and-trips problem written into one sentence. If any of those show up on a surface people cross, it needs to be cleaned, repaired, or guarded.
