OSHA 1910.22 Walking-Working Surface Requirements Explained

OSHA 1910.22 Walking-Working Surface Requirements Explained

A commercial facility can have properly installed fall protection equipment and still expose workers to hazards before they ever reach it.

A corroded rooftop walking surface. Ice around an access point. A leaking mechanical unit. An unsafe route to rooftop equipment. A walking surface that cannot support the intended load. A damaged area that remains accessible while waiting for repairs.

These conditions are addressed by one of the foundational standards in OSHA’s Walking-Working Surfaces regulations: 29 CFR 1910.22.

OSHA 1910.22 establishes general requirements for walking-working surfaces in general industry workplaces. It addresses four fundamental responsibilities:

• Surface conditions
• Load capacity
• Safe access and egress
• Inspection, maintenance and repair

For facility managers, building owners, safety professionals and contractors, understanding these requirements is important because OSHA 1910.22 establishes a foundation for the more specific ladder, stairway and fall-protection requirements found elsewhere in Subpart D.

What Is OSHA 1910.22?

OSHA 1910.22 is titled General Requirements and is part of 29 CFR 1910 Subpart D — Walking-Working Surfaces.

OSHA defines a walking-working surface broadly as a horizontal or vertical surface on or through which an employee walks, works or gains access to a work area or workplace location.

That makes 1910.22 relevant to far more than floors inside a building.

Depending on the workplace, walking-working surfaces can include areas workers use to access or perform work around commercial rooftops, mechanical areas, elevated work locations and other portions of a facility.

The core principle is straightforward:

If employees are expected to walk, work or gain access through an area, the employer needs to consider whether that surface and the route to it are safe.

The Four Main OSHA 1910.22 Requirements

For facility managers, the easiest way to understand 1910.22 is to divide the standard into four categories.

OSHA Section	Requirement
1910.22(a)	Surface conditions
1910.22(b)	Loads
1910.22(c)	Access and egress
1910.22(d)	Inspection, maintenance and repair

Let’s look at each individually.

1. OSHA Requirements for Walking-Working Surface Conditions

OSHA requires places of employment, passageways, storerooms, service rooms and walking-working surfaces to be maintained in a clean, orderly and sanitary condition.

OSHA also specifically addresses workroom floors.

They must be maintained in a clean and, to the extent feasible, dry condition. Where wet processes are used, OSHA requires drainage and, to the extent feasible, dry standing places such as platforms, mats or false floors.

For commercial facilities, this requirement extends beyond routine housekeeping.

OSHA specifically identifies hazards including:

• Sharp or protruding objects
• Loose boards
• Corrosion
• Leaks
• Spills
• Snow
• Ice

Walking-working surfaces must be maintained free of these types of hazards.

Why This Matters on Commercial Rooftops

Commercial roofs can present unusual walking-surface conditions.

A facility team may encounter:

• Ponding water near drains
• Ice around roof hatches
• Snow accumulation
• Corroded access platforms
• Leaking HVAC equipment
• Loose roofing components
• Trip hazards from piping or conduit
• Changes in elevation between roof sections
• Narrow paths between mechanical equipment

These conditions shouldn’t be evaluated independently from the work employees and contractors perform on the roof.

A rooftop may technically be accessible while the route to the work area remains hazardous.

2. Walking-Working Surfaces Must Support Their Intended Loads

OSHA 1910.22(b) contains a short but important requirement:

The employer must ensure each walking-working surface can support the maximum intended load for that surface.

This deserves attention in commercial and industrial environments.

A rooftop or elevated work area may be used by more than a single maintenance employee. Workers may bring:

• Tools
• Replacement components
• Mechanical equipment
• Materials
• Temporary work platforms
• Fall-protection equipment

Building modifications can also change how an area is used.

For example, an elevated platform originally intended only for occasional access might later become a regular maintenance area supporting workers and equipment.

Facility managers therefore need to consider not only whether workers can reach a location, but whether the walking-working surface is appropriate for its intended use.

3. OSHA Requires Safe Access and Egress

OSHA 1910.22(c) requires employers to provide—and ensure employees use—a safe means of access and egress to and from walking-working surfaces.

This is particularly relevant to commercial rooftop safety.

Consider the path a technician might follow to service an HVAC unit:

Interior stair → mechanical room → fixed ladder → roof hatch → rooftop → HVAC equipment

Each portion of that route may involve a different OSHA requirement.

The stairway may implicate 1910.25.

The fixed ladder may implicate 1910.23.

The rooftop walking-working surface falls within the broader Subpart D framework.

An unprotected edge may trigger 1910.28.

A guardrail or personal fall-protection system may need to satisfy 1910.29 or 1910.140, depending on the system involved.

This is why a facility shouldn’t evaluate rooftop safety solely by asking:

“Do we have anchors?”

The better question is:

“Can workers safely get from inside the building to the place where they need to work?”

4. OSHA Walking-Working Surface Inspection Requirements

This is one of the most important sections of 1910.22 for facility managers.

OSHA requires walking-working surfaces to be:

inspected regularly and as necessary and maintained in a safe condition.

Notice that OSHA does not establish one universal inspection interval in 1910.22(d)(1).

Instead, the requirement is regularly and as necessary.

That means a facility’s inspection program should account for the actual conditions of the workplace.

A commercial roof exposed to heavy snow, coastal corrosion, industrial contaminants or frequent contractor traffic may require a different inspection approach from a controlled interior work area.

What Happens When an Unsafe Condition Is Found?

Finding a hazard is only part of the process.

Under 1910.22(d)(2), hazardous conditions must be corrected or repaired before employees use the walking-working surface again.

If the condition cannot be corrected immediately, OSHA requires the hazard to be guarded so employees cannot use the affected walking-working surface until it has been corrected or repaired.

This is a significant facility-management requirement.

Finding a problem during an inspection and adding it to a future maintenance list may not be sufficient if workers remain exposed to the hazardous area.

The process should be:

Identify → Restrict/Guard if necessary → Correct → Return to service.

When Is a Qualified Person Required?

OSHA also addresses repairs involving structural integrity.

If a correction or repair affects the structural integrity of a walking-working surface, OSHA requires the work to be performed or supervised by a qualified person.

This becomes particularly relevant around:

• Elevated platforms
• Structural roof components
• Access systems
• Equipment platforms
• Structural supports
• Damaged walking surfaces

Facility teams should distinguish between ordinary maintenance and work that affects the structural integrity of the surface.

OSHA 1910.22 and Rooftop Fall Protection

OSHA 1910.22 does not establish all of the requirements for protecting workers from rooftop falls.

That distinction matters.

1910.22 establishes general requirements for the walking-working surface itself.

1910.28 establishes many of the employer’s duties to protect employees from fall hazards.

For example, except where another provision applies, OSHA generally requires fall protection when employees are on a walking-working surface with an unprotected side or edge 4 feet or more above a lower level.

Depending on the situation, protection may involve systems such as:

• Guardrails
• Safety nets
• Personal fall-protection systems
• Travel restraint
• Other systems permitted under the applicable OSHA provision

The correct solution depends on the specific hazard and work being performed.

Walking-Working Surface vs. Fall-Protection System

This distinction can help facility managers understand the regulations.

1910.22 asks: Is the surface and access route safe?

1910.28 asks: Is the employee appropriately protected from the fall hazard?

1910.29 asks: Does the required fall-protection system meet OSHA’s criteria?

1910.140 addresses: Requirements for personal fall-protection systems.

These standards work together.

A roof anchor doesn’t correct an unsafe walking surface.

Likewise, a perfectly maintained rooftop doesn’t eliminate the need for fall protection when workers are exposed to an applicable fall hazard.

OSHA 1910.22 and Commercial Roof Inspections

Commercial rooftops change over time.

New mechanical equipment is installed.

Roofing systems are replaced.

Solar equipment may be added.

Piping and conduit are rerouted.

New contractors access areas that historically saw little foot traffic.

Access paths change.

That means a rooftop safety assessment performed years ago may no longer accurately represent current conditions.

A useful commercial rooftop assessment should consider:

• Condition of walking surfaces
• Safe access and egress
• Roof hatches
• Fixed ladders
• Stairs
• Changes in elevation
• Roof edges
• Skylights and openings
• Mechanical equipment locations
• Existing anchors
• Horizontal lifelines
• Guardrails
• Worker travel paths
• Contractor access

The objective is to understand how the roof is actually being used today.

Common OSHA 1910.22 Issues at Commercial Facilities

Corrosion
OSHA specifically lists corrosion among the hazards walking-working surfaces must be maintained free from.
Outdoor platforms, ladders and metal walking surfaces can deteriorate over time, especially in coastal or industrial environments.

Snow and Ice
Snow and ice are also specifically identified by OSHA.
For facilities in cold climates, rooftop access procedures should account for seasonal conditions.

Leaks
Leaks from roofing systems or mechanical equipment can create slip hazards and contribute to deterioration.

Unsafe Access Routes

A roof may be structurally sound while the route to it presents hazards.

Changes After Construction

New rooftop equipment can unintentionally create narrow pathways, obstructions or work areas closer to edges.

These are good examples of why regular inspection matters.

1910.22 Is Part of OSHA Subpart D

OSHA’s Walking-Working Surfaces regulations include several standards facility managers should understand:

• 1910.21 — Scope and Definitions
• 1910.22 — General Requirements
• 1910.23 — Ladders
• 1910.24 — Step Bolts and Manhole Steps
• 1910.25 — Stairways
• 1910.26 — Dockboards
• 1910.27 — Scaffolds and Rope Descent Systems
• 1910.28 — Duty to Have Fall Protection
• 1910.29 — Fall Protection Systems Criteria and Practices
• 1910.30 — Training Requirements

For commercial building owners, these standards shouldn’t be treated as isolated rules.

A worker accessing one rooftop work location may encounter several of them during the same task.

Building a Practical Walking-Working Surface Program

A practical facility program can begin with four questions:

1. Where do employees and contractors work?
Identify rooftops, mechanical areas, elevated platforms and other walking-working surfaces.

2. How do they get there?
Document stairs, fixed ladders, hatches and other access points.

3. What hazards exist along the route?
Evaluate surface conditions, structural condition, openings, edges, elevation changes and obstructions.

4. What protection is already installed?
Document guardrails, roof anchors, horizontal lifelines, ladder safety systems and other fall-protection equipment.

This provides a more complete picture than inspecting one piece of equipment at a time.
