Walking-working surfaces refers to any horizontal or vertical surface on which employees walk or work, including floors, stairs, and platforms.

A regulatory category covering any surface — floors, aisles, stairways, ladders, platforms, and similar areas — on which employees walk or perform work, governed in the U.S. by OSHA's Walking-Working Surfaces standard (29 CFR 1910 Subpart D), which addresses slip, trip, and fall prevention.
A facility installs slip-resistant matting and ensures handrails are present on all stairways as part of its compliance with walking-working surfaces requirements.
It covers a wide range of topics including floor and stairway conditions, ladder safety, fixed and portable ladder use, personal fall protection systems, and rope descent systems.
OSHA significantly updated this standard in 2016 to add requirements for personal fall protection systems and align more closely with construction industry fall protection rules.
Common hazards include uneven or damaged flooring, unguarded floor holes, improper ladder use, and lack of fall protection at elevated walking-working surfaces.
