Walking-working surfaces are any horizontal or vertical surfaces on or through which employees walk, work or gain access to a work area, such as floors, stairs, ladders, ramps, roofs, platforms, runways and dockboards. In OSHA's general industry rules, they are governed by 29 CFR 1910 Subpart D, which addresses slip, trip and fall hazards and sets fall protection requirements.
Slips, trips and falls are among the most common causes of workplace injuries, and falls from height are a leading cause of work-related deaths. Keeping walking-working surfaces safe is one of the most basic, and most important, parts of any workplace safety program.
What Are Walking-Working Surfaces?
OSHA's definition is broad. It covers nearly every surface a worker stands or moves on, including:
- Floors, aisles and passageways.
- Stairs, ramps and runways.
- Portable and fixed ladders, and step bolts.
- Platforms, mezzanines and elevated walkways.
- Roofs, including low-slope roofs.
- Loading docks and dockboards.
- Scaffolds and rope descent systems used in general industry.
According to OSHA, the general industry walking-working surfaces rule applies to all general industry workplaces and covers all walking-working surfaces. Construction and agriculture are covered by separate standards.
The 2016 Walking-Working Surfaces Final Rule
On November 18, 2016, OSHA published a major update to its general industry walking-working surfaces standards (Subpart D) and added requirements for personal fall protection systems (Subpart I). Most of the rule took effect on January 17, 2017. According to OSHA's final rule page, the update:
- Removed the requirement to use guardrails as the primary method of fall protection, allowing employers to choose from accepted fall protection systems.
- Allowed designated areas on low-slope roofs for work that is temporary and infrequent.
- Aligned general industry fall protection more closely with construction standards, and replaced the general industry scaffold requirements with the construction scaffold standards.
- Added training and inspection requirements.
OSHA estimated the rule would prevent 29 fatalities and 5,842 lost-workday injuries every year.
Compliance Dates
- May 17, 2017: train exposed workers on fall hazards and on the equipment covered by the rule.
- November 20, 2017: inspect and certify permanent anchorages for rope descent systems.
- November 19, 2018: install personal fall arrest or ladder safety systems on new fixed ladders over 24 feet, and on replacement ladders and ladder sections. Existing fixed ladders over 24 feet must have a cage, well, personal fall arrest system or ladder safety system.
- November 18, 2036: under the 2016 rule, cages and wells used as fall protection on fixed ladders over 24 feet must be replaced with ladder safety or personal fall arrest systems.
In April 2026, OSHA proposed removing the November 18, 2036 deadline so that existing fixed ladders could be upgraded at the end of their service lives. Under the proposal, new fixed ladders over 24 feet would still need a personal fall arrest or ladder safety system. Employers should check OSHA for the current status of this rulemaking.
Key Requirements of Subpart D
General Requirements (1910.22)
Under 29 CFR 1910.22, employers must:
- Keep workplaces and walking-working surfaces clean, orderly and sanitary, and free of hazards such as sharp or protruding objects, loose boards, spills, snow and ice.
- Make sure each surface can support its maximum intended load.
- Provide and ensure the use of a safe means of access and egress.
- Inspect walking-working surfaces regularly and as necessary, and correct, repair or guard hazardous conditions before employees use the surface again.
- Have a qualified person perform or supervise repairs that involve the structural integrity of a surface.
Ladders (1910.23)
The ladder rules cover portable, fixed and mobile ladders. Among other requirements, ladders must be inspected before initial use in each work shift, and more often as needed, for visible defects that could cause injury. Defective ladders must be immediately tagged as dangerous and removed from service until repaired or replaced. Employees must face the ladder when climbing up or down and use at least one hand to grasp it, and they may not carry any object or load that could cause them to lose balance and fall.
Duty to Have Fall Protection (1910.28)
Under 29 CFR 1910.28, employers must protect workers on unprotected sides or edges that are 4 feet or more above a lower level, using guardrails, safety nets or personal fall protection systems such as fall arrest, travel restraint or positioning systems. The section also covers holes, dangerous equipment, wall openings, fixed ladders, stairways and low-slope roofs. For example, on low-slope roofs the requirements differ depending on whether work is less than 6 feet, between 6 and 15 feet, or 15 feet or more from the roof edge. See fall protection for more on these systems.
Training (1910.30)
Before any employee is exposed to a fall hazard, the employer must provide training by a qualified person. Training must cover the nature of fall hazards in the work area, procedures to minimize them, and the correct installation, inspection, use and maintenance of the fall protection systems the employee uses. Employers must retrain employees when workplace changes or equipment changes make earlier training obsolete, or when an employee's knowledge or use of equipment shows it is inadequate. Training must be provided in a manner the employee understands.
Common Walking-Working Surface Hazards
- Slip hazards: wet or oily floors, spilled product, ice, polished surfaces and loose mats.
- Trip hazards: cords and hoses across walkways, uneven flooring, clutter, damaged stair treads and poor lighting.
- Fall from height hazards: unguarded platform edges, open holes and skylights, damaged ladders and unprotected roof edges.
- Structural hazards: overloaded mezzanines, corroded grating and damaged dock plates.
How to Manage Walking-Working Surfaces Step by Step
- Inventory your surfaces. List floors, stairs, ladders, platforms, roofs, docks and other elevated areas in each facility.
- Identify hazards. Walk the site and use incident and near miss data to find where slips, trips and falls occur.
- Set inspection routines. Build regular surface and ladder inspections into daily, weekly or monthly checklists, depending on risk.
- Choose fall protection. For each elevated area, decide on guardrails, covers, travel restraint, fall arrest or another accepted method, following the hierarchy of controls.
- Fix and track hazards. Repair or guard problems promptly and track corrective actions to closure.
- Train workers. Provide fall hazard and equipment training before exposure, and retrain when conditions change.
- Review and improve. Use audits to check that housekeeping, inspections and fall protection are working.
Examples
- A food processing plant installs anti-slip flooring and drainage in a wash-down area after repeated slip injuries.
- A distribution center adds a gate and guardrail to a mezzanine pick module where workers previously stood at an open edge to receive pallets.
- A maintenance team tags out a stepladder with a cracked side rail found during a pre-shift inspection and replaces it the same day.
- A facility retrofits a fixed roof access ladder over 24 feet with a ladder safety system during a scheduled replacement.
Best Practices
- Clean up spills immediately and use signs or barriers until surfaces are dry.
- Keep aisles and exits clear and well lit.
- Use cord covers or overhead routing for cables and hoses.
- Choose the right ladder for the job, and inspect it before each shift.
- Provide slip-resistant footwear where floors are routinely wet or greasy.
- Include walking-working surfaces in job hazard analyses and toolbox talks.
How SMS360 Helps
The SMS360 Audit Management module lets teams build inspection checklists for floors, stairs, ladders, platforms and roof access points and complete them on a mobile device. Failed items can generate corrective actions with owners and due dates, and inspection records help show that walking-working surfaces are being inspected regularly and that hazards are fixed.
