A person can be injured by machinery in several ways: crushing hazards from being trapped between moving and fixed parts; shearing hazards from having body parts trapped; cutting or severing hazards from contact with sharp edges; entanglement hazards from loose clothing or materials wrapping around revolving parts; drawing-in or trapping hazards such as between gears or rollers; impact hazards from direct strikes by moving parts; stabbing or puncture hazards from ejected particles or sharp components; contact with friction or abrasion hazards; or high-pressure fluid injection hazards. Injuries may involve multiple hazards in sequence, such as contact leading to entanglement and trapping.
