Sample Video Transcript
Fatigue leads to an impairment in task performance and is a serious threat to workplace safety. According to OSHA, the risk of injury is 30% greater on night shifts compared to day shifts and fatigue has been identified as a contributing factor in some of the most significant disasters of our time: The Three Mile Island nuclear accident, the grounding of the oil tanker Exxon Valdez off the coast of Alaska, and the BP Texas City Refinery explosion. The most important effects of fatigue are: • Reduced alertness • Impaired ability to concentrate • Slowed reaction time • Problems with memory and information processing • Poor judgment Research has shown that the number of hours awake can be related to blood alcohol levels. WorkSafeBC in Canada reported that: • 17 hours awake is equivalent to a blood alcohol content of 0.05 • 21 hours awake is equivalent to a blood alcohol content of 0.08 (the legal limit for driving in many states)
