Incidents are decreasing but remain highly dangerous
OSHA has documented 280 severe cases involving same-level slips and trips that did not result in a fall. These incidents frequently lead to serious outcomes, with fractures accounting for 34.4% of all reported injuries.
The impact on the body is significant, as 26.7% of these incidents result in severe ankle injuries. Many workers also experience traumatic musculoskeletal damage, often requiring surgery to address complex fractures or torn ligaments.
Over the last decade, reported incidents have decreased by 60.4%, though the 5-year trend shows an 11.8% increase. Bodily motion remains the primary source of injury in 67.3% of cases, indicating that the way workers move across their environment is a critical safety factor.
Manufacturing and construction industries lead in these reports, accounting for a combined 39.3% of all cases. These environments often feature complex floor surfaces and high-traffic areas that increase the risk of a sudden, injury-causing stumble.
Top causes based on OSHA incident reports
These injuries typically occur when a worker encounters an unexpected change in floor surface or loses balance during routine tasks. Constructed surfaces and uneven ground are involved in 21.8% of reported cases, often creating hidden hazards that cause workers to twist joints or strain muscles while simply walking or carrying equipment.

Employers are legally required to maintain safe walking-working surfaces under 29 CFR 1910.22. Failure to keep floors clean, dry, and free of protruding objects or raised areas constitutes a violation of these federal safety standards, which are designed to prevent the exact mechanisms that lead to these severe fractures.
Where these injuries occur most frequently
Manufacturing accounts for 23.6% of all reported same-level incidents, followed by construction at 15.7%. These industries require workers to navigate around machinery, debris, and varying floor elevations, which significantly elevates the risk of a trip or stumble.
In these high-risk sectors, employers must adhere to 29 CFR 1910.22(a) to ensure all places of employment are kept in a clean, orderly, and sanitary condition. Regular inspections and the immediate repair of floor defects are mandatory requirements to protect workers from these preventable musculoskeletal injuries.
From actual OSHA investigation files
Reported incidents consistently reveal that severe injuries often occur during routine movements, such as stepping onto platforms or walking across parking lots. These accounts highlight how minor floor irregularities or slick surfaces can lead to compound fractures and long-term disability, even when the worker does not actually fall to the ground.
"An employee was preparing to conduct a 6-foot welding operation to repair a ladle plate. When he stepped forward on a scaffolding platform to conduct the weld, his right foot slipped and his right ankle was wrenched and broken. He was hospitalized."
"An employee was walking across the parking lot from his vehicle to the facility when he suffered a twisted left ankle that resulted in an open compound fracture."
"An employee tripped on a raised area of the floor while walking and stumbled but did not fall, aggravating an inguinal hernia. The employee was hospitalized and required surgery."
"On June 2, 2025, an employee was applying labels to boxes and began walking away when they missed a step and twisted their left ankle. The employee sustained a fractured left ankle."
"An employee was washing the chutes of a concrete mixer truck. When he went to move one of the chutes, he slipped in the mud, twisting his back. The employee sustained a strained back."
"An employee was performing concrete work as part of a crew for the construction of a new building when they slipped on a gravel surface and their knee twisted. The employee was hospitalized with a torn ligament/tendon in the knee that required surgery."
"An employee was responding to an emergency call at the end of a pier when they stepped into a gap in the pier boards, resulting in a broken tibia, fibula, and ankle."
"An employee was pulling the hose on a concrete pump truck when they slipped, causing their leg to become caught in the step. The employee was hospitalized with a fractured leg."
"An employee was walking on a plywood boardwalk in an alcove between two walls of a building that was under construction. He turned, stumbled, and had to lunge to correct himself. His right foot was caught in a divot as he spun, and he fractured and sprained his right ankle. He was hospitalized."
"An employee was walking through the kitchen when they slipped and strained their lower back, resulting in hospitalization."
