The purpose of the paper is to give an introduction to the concept of
fatigue and its causes in the mining industry. By knowing the
fundamental role it plays, together with its dynamics, can positively
contribute to a mine’s safety management system. The difference
between physical and psychological fatigue will be addressed with a
possible range of causes that could trigger fatigue. There are two
main sources of fatigue: firstly, work-related fatigue which is
associated with activities at the workplace; and secondly non-workrelated
fatigue. The shared responsibility between the employer and
employee is also discussed as it involves factors that occur both in
and outside the workplace. Employers have the responsibility to
manage fatigue through using a risk management approach.
Employees have the responsibility to ensure they get enough sleep,
take sufficient and regular nutrition, are healthy and physically fit
and come to work fresh and alert. The impact of the implementation
of a fatigue management plan and procedures has the potential to
eliminate employee fatigue or its causes, reduce the likelihood of
fatigue occurring in the workplace, and counteract the effects of
fatigue when it occurs. Factors considered when implementing a
fatigue management system include: extended hours of work, shift
work, time of day and work design.
Fatigue is one of the major role players (either causal or
contributory) when it comes to causes of fatalities in the mining
industry. Our main challenge in identifying whether fatigue played
a role is the fact that it cannot be tested in post-mortems like drug
or alcohol abuse. It is an aspect worth understanding and getting an
organization sensitive to managing it properly to benefit both
organizational as well as employee needs.
