Effects of fatigue onperformance and productivity

Source: Extended working hours in Australia: counting the costsDepartment 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.”

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.”

“Sleep deprivation has been associated with an impairment of low-level tasks, including visual perception, vigilance, reaction time and mental arithmetic..”

encounters with colleagues.”

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.”

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.

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.

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

Develop a fatigue management strategy

Scenario

You are managing the shutdown for refurbishing of a piece of equipment that is essential in the processing plant. Previously, the equipment has been offline for 48 hours during this procedure.

How might you build fatigue management into the schedule?
