Fatigue Management
Fatigue Management focuses on the health and safety of workers and others due to risk of fatigue. Shell defines fatigue as a ‘lack of mental alertness, or drowsiness, arising from lack of sleep. Fatigue-associated impairment is an identifiable and potentially preventable workplace hazard.
Most adults need 7–9 hours sleep in each 24-hour period to feel well rested and fit for work. If someone consistently has less sleep they will carry a sleep debt, which may result in impaired performance, reduced alertness and higher levels of sleepiness and/or fatigue. A sleep debt can only be repaid with restorative sleep.
