Forensic human factors and ergonomics analysis of a trip and fall event in a parking lot

Abstract

ABSTRACTBuilt (constructed) environments should have level surfaces to promote mobility and avoid injuries from trips and falls. Wheel stops (usually long concrete slabs with metal bolts to hold them in place) are sometimes placed in parking lots to limit and control how drivers position their vehicle in designated spaces. However, they present potential problems for pedestrians traversing through the area as they can cause trips and falls. A forensic human factors and ergonomics (HFE) analysis of a trip and fall event involving a wheel stop and its bolts in a parking lot is presented. The factors of visual obstruction, salience, attention, expectancy, and relevance issues are discussed. Additionally, an alternative analysis involving hazard control is presented. Potential solutions to limit risk to pedestrians and property owners are described.
