Fatigue Why is fatigue important?
Poorly designed shift-working arrangements and long working hours that do not balance the demands of work with time for rest and recovery can result in fatigue, accidents, injuries and ill health.
Fatigue refers to the issues that arise from excessive working time or poorly designed shift patterns. It is also related to workload, in that workers are more easily fatigued if their work is machine-paced, complex or monotonous. Fatigue results in slower reactions, reduced ability to process information, memory lapses, absent-mindedness, decreased awareness, lack of attention, underestimation of risk, reduced coordination etc.
Fatigue can lead to errors and accidents, ill-health and injury, and reduced productivity. It is often a root cause of major accidents e. Key principles in fatigue Fatigue needs to be managed, like any other hazard.
It is important not to underestimate the risks of fatigue. For example, the incidence of accidents and injuries has been found to be higher on night shifts, after a succession of shifts, when shifts are long and when there are inadequate breaks. Compliance with the Working Time Regulations alone is insufficient to manage the risks of fatigue.
Changes to working hours need to be risk assessed.
Employees should be consulted on working hours and shift patterns. However, note that employees may prefer certain shift patterns that are unhealthy and likely to cause fatigue. Develop a policy that specifically addresses and sets limits on working hours, overtime and shift-swapping, and which guards against fatigue.
Implement the policy and make arrangements to monitor and enforce it. This may include developing a robust system of recording working hours, overtime, shift-swapping and on-call working. Problems with overtime and shift-swapping may indicate inadequate resource allocation and staffing levels.
There are many different shift work-schedules and each schedule has different features. This sheer diversity of work and workplaces means that there is no single optimal shift system that suits everyone.
However, a planned and systematic approach to assessing and managing the risks of shift work can improve the health and safety of workers. There are a number of key risk factors in shift schedule design, which must be considered when assessing and managing the risks of shift work.
These are the workload, the work activity, shift timing and duration, direction of rotation and the number and length of breaks during and between shifts. Other features of the workplace environment such as the physical environment, management issues and employee welfare can also contribute to the risks associated with shift work.
Night workers are particularly at risk of fatigue because their day sleep is often lighter, shorter and more easily disturbed because of daytime noise and a natural reluctance to sleep during daylight. More information on fatigue.Fatigue risk management systems (FRMS) is an industry accepted, data driven means of continuously monitoring and managing fatigue in the workplace.
Based on scientific principles, this course will introduce systems, processes, and controls that optimize efficiency, ensure safety, and meet the applicable regulatory requirements. ATSB TRANSPORT SAFETY REPORT Aviation Research and Analysis Report - B Final How Old is Too Old?
