OSHA’s Walking-Working Surfaces standard represents one of the most critical and frequently cited regulations in general industry, impacting nearly every task performed on a floor or elevated platform. Officially codified in 29 CFR 1910.22, this regulation establishes the foundation for safe mobility, ensuring that employees can traverse surfaces without the ever-present risk of slips, trips, and falls. Unlike prescriptive rules that dictate exact specifications for every scenario, the standard focuses on performance-based requirements, placing the responsibility on employers to maintain surfaces that are, at a minimum, clean, orderly, and maintained in a sanitary condition. This framework demands a proactive approach to safety management, moving beyond simple cleanup to address the root causes of surface failures and human error.
Understanding the Scope and Application
The standard applies to all permanent places of employment, encompassing the full breadth of a facility’s interior and exterior surfaces where employees are required to walk or work. This includes not only traditional walkways but also ramps, stairs, runways, and temporary surfaces like staging or scaffolding. The core mandate is straightforward: surfaces must be kept clean and, where necessary, dry to prevent accidents. Employers are required to ensure that these conditions are maintained as a standard practice, integrating surface integrity into their broader facility management and housekeeping protocols to eliminate hazards before they can cause injury.
Key Requirements for Walking and Working Surfaces
To comply with the standard, employers must adhere to three primary performance criteria for all walking and working surfaces. First, surfaces must be kept clean and, to the extent necessary, dry, which requires active management of spills and environmental conditions like humidity or weather tracking in from outside. Second, these surfaces, including their edges, must be designed, installed, and maintained with sufficient strength and structural integrity to safely support all anticipated loads, including people and equipment. Finally, the standard explicitly prohibits any intentional openings in these surfaces, with exceptions for specific scenarios like ventilation or access points, which must be guarded to prevent employees from accidentally falling through.
The Critical Role of Housekeeping and Maintenance
Effective housekeeping is the most visible and immediate application of the standard, serving as the first line of defense against workplace injuries. Employers must establish a routine schedule for removing hazards such as waste, debris, water, oil, or any other substance that could create a slip or trip hazard. This extends to ensuring that drainage systems are clear and functional, preventing the accumulation of water that could make surfaces treacherous. A well-executed maintenance program treats floor conditions with the same urgency as equipment uptime, recognizing that a clean surface is a safe surface.
Managing Openings and Raised Edges
Guarding Floor and Wall Openings
Openings in floors, walls, or any surface pose a significant fall hazard and are strictly regulated by the standard. Every hole, regardless of size, must be guarded by a railing system or a cover that is securely attached to prevent displacement. If a cover is used, it must be capable of supporting at least twice the maximum weight of employees expected to be on it, providing a critical margin of safety. These requirements ensure that employees can work near openings without the constant fear of falling through, a scenario that often results in severe injury.
Managing Raised or Uneven Surfaces
Changes in elevation, such as platforms, runways, and ramps, must be carefully managed to prevent trips and falls. The edges of these surfaces require guardrail systems that meet specific height and strength criteria to contain employees safely. Furthermore, standard stairs must be equipped with handrails on both sides, positioned at a height that is ergonomically accessible. The regulation also addresses weather-related hazards, requiring that ramps and walkways be equipped with slips-resistant surfaces or appropriate coverings when exposed to weather conditions that could make them wet or icy.
