OSHA 1910.22(a)(1) requires workplaces to be maintained in a clean and orderly condition. Spills must be cleaned up immediately, not when convenient. This is one of the most frequently cited general industry violations. Many slip incidents occur when a spill is known but cleaning is deferred for even a short time.

OSHA requires aisles used by powered industrial trucks to be at least 3 feet wider than the widest vehicle. Pedestrian aisles must be sufficient for safe two-way movement. Stacking inventory in aisles, even temporarily, creates both a trip hazard and a violation. Aisle markings are required where traffic hazards exist.

Floor surface condition is a direct requirement of 1910.22. Damaged floors must be repaired promptly. Loose anti-fatigue mats with curled edges are a leading cause of trips in manufacturing and food processing environments. Raised door thresholds between different floor surfaces are consistently overlooked in inspections. Any projection above the floor surface that a walker cannot anticipate is a trip hazard.

When wet or slippery conditions are inherent to the work (food processing, chemical mixing, wet cleaning), wet floor signs alone are not adequate. OSHA expects engineering controls: drainage to remove standing water, textured or coated flooring, slip-resistant mats that are secured at the edges and cleaned regularly. Temporary “wet floor” cones are only appropriate for transient spills, not ongoing slippery conditions.

Poor lighting is a major contributor to slip, trip and fall incidents. Workers cannot avoid hazards they cannot see. OSHA does not specify minimum foot-candle levels in 1910.22 directly, but the general duty clause requires illumination adequate for the tasks performed. ANSI/IES lighting standards are commonly referenced. Burned-out lights must be replaced promptly. Outdoor areas used at night require specific illumination planning.

Outdoor surface hazards are frequently overlooked in slip, trip and fall programmes that focus on interior floors. Cracked or heaved pavement, potholes at vehicle transition points, ice on loading dock approaches, and overgrown vegetation obscuring pathway edges are all common causes of injuries. Seasonal hazard management (ice removal, drainage clearing after rain) must be part of the programme.

Floor openings 2 inches or more in the least dimension are covered by OSHA’s hole cover requirements. Covers must be capable of supporting the maximum intended load without deflection, be secured to prevent accidental displacement, and be marked to indicate they are hole covers. A piece of plywood laid over an opening without fastening is not a compliant cover. Drain grates that create a trip hazard for heel or cart wheels also require attention.

OSHA’s walking-working surfaces standard (1910.28) requires fall protection when workers are exposed to a fall of 4 feet or more in general industry. Guardrail systems must include a top rail at 42 inches (plus or minus 3 inches), a mid-rail at 21 inches, and be capable of withstanding 200 pounds of force. Self-closing gates are required where guardrails are interrupted for material handling access. Loading docks that are not actively receiving materials must be guarded.

Guardrails that are too low, missing mid-rails, or lacking toe boards are common violations. Toe boards must be at least 3.5 inches tall and are required wherever workers are working below the elevated level and falling objects could cause injury. Many facilities install guardrails to the correct height but omit toe boards entirely. The combination of top rail, mid-rail, and toe board forms the complete required system.

Loading dock edges are one of the highest-fall-risk locations in warehouse and distribution facilities. When a dock bay is not actively receiving a vehicle, the open edge represents a fall of typically 4 to 6 feet to the dock apron below. Dock levellers left in the extended position unsupported and dock plates left unsecured on the floor are common trip hazards. Dock safety chains or barriers must be in place when bays are not in use.

Scaffold and elevated work platform falls are among the most fatal workplace incidents. OSHA requires fall protection for scaffolding at 10 feet in construction and 4 feet in general industry. Mobile elevating work platforms (boom lifts, scissor lifts) require harness and lanyard use in most configurations. Pre-use inspection by a competent person is mandatory. Unauthorised or untrained workers operating elevated equipment are both a safety and a compliance risk.

Stairway handrails must be between 30 and 38 inches measured vertically from the leading edge of the stair tread. Both sides require handrails where 4 or more employees use the stairway. Single-sided handrails on high-traffic stairs are a common violation. Handrails must be continuous without gaps or interruptions that would force a user to release grip. Decorative railings that do not meet the height requirement or are not graspable are non-compliant.

Portable ladder failures are a leading cause of serious fall injuries. OSHA requires ladders to be inspected before each use by the user. Cracked fibreglass rungs, bent aluminium rails, and worn non-slip feet are all disqualifying defects. Common misuse includes using the top two rungs of a step ladder, using a ladder at an incorrect angle (the 4-to-1 rule: one foot out for every four feet up), and setting ladders on boxes or equipment to gain height.

The 4-to-1 rule means for every 4 feet of height, the base should be 1 foot from the wall. A ladder reaching a 16-foot height must have its base 4 feet from the wall. When accessing a roof or elevated surface, the ladder must extend at least 3 feet (36 inches) above the roofline or landing. An unsecured ladder that can kick out at the base or tip sideways is responsible for a significant proportion of ladder fatalities.

Carrying materials on a ladder breaks the three-point contact rule, which requires two hands and one foot or two feet and one hand on the ladder at all times. Workers carrying tools, containers, or supplies in both hands cannot maintain three-point contact. A tool belt or bucket is acceptable for small items. Bulk materials or heavy items must be hoisted separately. Many employers allow material carrying on ladders as a practical shortcut that creates serious fall risk.

Personal fall arrest systems (PFAS) are required when other forms of fall protection (guardrails, hole covers) are not feasible or are temporarily removed. A PFAS must include a full-body harness, a connecting lanyard or self-retracting lifeline, and a suitable anchorage point rated for at least 5,000 pounds per attached worker. Improper anchorage to non-rated structures (pipes, conduit, ductwork) is a common and potentially fatal error.

Proactive inspection is the single most effective way to prevent slip, trip and fall incidents. Inspections should cover all walking surfaces, aisles, stairs, outdoor areas, and elevated surfaces on a defined schedule. Findings must be documented and corrective actions tracked to completion. A verbal “I walked the floor” without a written record provides no defence during an OSHA inspection and no data for trend analysis.

Workers who observe hazards are the most effective early warning system in any workplace. If there is no easy way to report, or if past reports were ignored, workers stop reporting. A good hazard reporting system is simple (verbal, app, card, QR code), non-punitive, and closes the loop by telling the reporter what action was taken. Hazards that are reported and not corrected become evidence of employer knowledge in subsequent incident litigation.

OSHA 1910.30 requires training for all workers who use personal fall protection systems, work on walking-working surfaces, or are exposed to falling object hazards. Training must be conducted by a qualified person, be specific to the hazards present, and cover recognition, avoidance, and the proper use of any protection equipment used. Generic “slips trips and falls” awareness videos without site-specific content are frequently insufficient.

Footwear is a last line of defence against slips, but it is a meaningful one. Smooth-soled shoes, worn treads, or leather-soled dress shoes on a wet tile or epoxy floor dramatically increase slip risk. OSHA does not specify footwear in 1910.22 directly, but slip-resistant footwear requirements flow from the PPE hazard assessment requirements of 1910.132. Workers whose job tasks involve wet surfaces must be required to wear slip-resistant footwear as part of a comprehensive STF control programme.

Incident investigation is a learning opportunity. STF incidents often share root causes: inadequate housekeeping, poor lighting, missing or inadequate guardrails, or footwear not matched to the surface. Near-miss reporting is even more valuable than incident reporting because it identifies hazards before injury occurs. An organisation that only responds to injuries and ignores near-misses misses the majority of its risk reduction opportunity.

An STF programme without periodic review accumulates gaps over time. New surfaces are added, conditions change seasonally, and controls degrade. Annual programme review should examine incident and near-miss trends, outstanding corrective actions, surface inspection findings, and whether training remains current. Facilities with rising STF incident rates despite an existing programme almost always have a programme review gap.
