6 2009 Mines Safety Roadshow Effects of fatigue on performance and productivity Source: Extended working hours in Australia: counting the costs Department of Industrial Relations, Queensland, 2001 1.Ability to comprehend complex situations without distraction …after one night of sleep deprivation, individuals lost attention during decision making to miniscule details that had no impact on the situation outcome. 2.Monitoring events and improving strategies …subjects became distracted from critical tasks…and took longer on tasks that had been dealt with quickly before. 6

7 2009 Mines Safety Roadshow Effects of fatigue on performance and productivity (continued) 3.Risk assessment and accurate prediction of consequences …fatigued individuals are more likely to engage in risk taking behaviours. 4.Thinking laterally and being innovative …innovative thinking and the generation of ideas showed obvious deterioration. These latter skills are essential in dealing with complex and unpredictable situations. 7

8 2009 Mines Safety Roadshow Effects of fatigue on performance and productivity (continued) 5.Personal interest in the outcome …a sense of futility interferes with the willingness to apply effort. 6.Controlling mood and behaviour Mood states and behaviours, including lack of regard for normal social conventions, childish humour, impatience, irritability and inappropriate interpersonal behaviours have all been described… 8

9 2009 Mines Safety Roadshow Effects of fatigue on performance and productivity (continued) 7.Monitoring personal performance Sleep deprivation has been associated with an impairment of low-level tasks, including visual perception, vigilance, reaction time and mental arithmetic.. 8.Recollection of timing of events Sleep deprivation may confuse individuals when remembering serial ordering of facts, events, instructions, or encounters with colleagues. 9

10 2009 Mines Safety Roadshow Effects of fatigue on performance and productivity (continued) 9.Effective communication …during sleep deprivation, subjects dropped the intensity of their voice, paused for long intervals without apparent reason, enunciated very poorly or mumbled instructions inaudibly, mispronounced, slurred or ran words together and repeated themselves or lost their place in the sequence. …sleep deprivation was found to increase response reaction time to received messages in a setting of constant distraction. 10

18 2009 Mines Safety Roadshow Lessons for mining industry Intense work (e.g. complex tasks, time pressures, high responsibility) creates difficulty in switching off and unwinding, while shift work, situational constraints, low autonomy, and closely-regulated work tend to reduce individuals control over their work pace, and increase the effort required. Under such conditions, there is a greater need for rest and recovery. 18

19 2009 Mines Safety Roadshow What is rest Rest involves a break from work, but not doing nothing A change of activity, and associated change in demands, may have an equally, or greater, beneficial effect.

20 2009 Mines Safety Roadshow What is rest that works? Enjoyable social leisure activities Not low effort activities (watching TV) Physical activities facilitate recovery Work-related activity during leisure hours has a consistently negative effect Source: Katharine R Parkes, Offshore working time in relation to performance, health and safety, A review of current practice and evidence. 20
