Slips and falls are a major cause of serious injury, disability and death at work. This research focus on slips and falls events due to contamination factors on different ramp angles among workers because employees are exposed to such danger at the workplace. The goals of this study were to identify; the main factors that cause slips and falls on inclined surfaces, the effects of contaminants on gait, and walking speed downhill before the slips occur. Three different contaminants variaty in viscosity (water, suds and oil), three ramp angels (3?, 7? and 14?) and two shoe types ( Saftey boot and Sneaker) were used during the trials. In addition, eight healthy male subjects (22-28 years) were asked to walk as naturally as possible throught testing. This project produced an outcome of the slip distance based on the interaction of the factors that causes the incident of slips and falls. As a resualt, slope and contaminant factors are known as the main elements that increase the risk of sliping and falling on ramps. Furthermore, the walking speed increase while the ramp angle will rise. Based on the result, suggestion and guideline can be produce to overcome the slips and falls instances
