Workplace fatigue is a major concern in high-risk industries which require not only physical endurance but also mental sharpness to ensure safety and productivity. Fatigue can significantly impair a worker's ability to perform tasks safely, leading to costly mistakes, incidents and injuries. Therefore, managing workplace fatigue is crucial for both employee wellbeing and operational success. This article explores the dangers of workplace fatigue and practical strategies to reduce the risks in high-risk industries.
Fatigue in the workplace doesn't just affect productivity, it can be a direct threat to safety, particularly in high risk industries where workers often operate heavy machinery, perform complex tasks or are responsible for others' lives. Fatigue is a hazard and may be identified as a risk.
Fatigue can be physically evident in people through a few ways outlined below.
Fatigue slows reaction times and reduces attention to detail, which are essential for hazard identification and risk mitigation. Studies show that after 17 hours without sleep, cognitive impairment can be similar to having a blood alcohol concentration (BAC) of 0.05%.
Physically demanding tasks become riskier when workers are fatigued. Muscle fatigue affects coordination and strength, increasing the likelihood of workplace incidents such as slips, trips and falls.
Fatigue can contribute to irritability, mood swings and stress, which may reduce the effectiveness of communication and create tension among team members. In high risk industries, clear and effective communication is essential to avoid misunderstandings that could lead to dangerous situations.
Over time, persistent fatigue can contribute to long-term health issues such as cardiovascular diseases, musculoskeletal disorders and mental health issues. This can impact the overall safety culture of the workplace, along with long term productivity.
Not only is the effective scheduling of shifts ideal for reducing fatigue, but it is also a legal requirement. A person conducting a business or undertaking (PCBU) has a duty under the model WHS laws to do all they can reasonably do to manage the risk of fatigue in the workplace. Consider the following methods for optimising work schedules to reduce fatigue and allow workers enough time for rest between shifts.
Different contractors have varying standards for compliance. Subcontractors must take the time to understand each principal contractor’s unique requirements, which may differ from project to project.
Workload management is crucial in reducing fatigue among workers. Properly distributing tasks ensures no employee is overburdened and tasks are completed efficiently and safely.
Investing in employee health and wellness is one of the most effective ways to combat workplace fatigue. When workers feel physically and mentally healthy, they are less likely to suffer from fatigue, which in turn improves safety and productivity.
Utilising technological solutions is a great way to streamline the management of fatigue in high risk workplaces. By having a digital system that checks in on worker fatigue, access to high risk sites and the scheduling of breaks can be managed by asking staff to answer questions about their fatigue levels. These systems can also allow workers to report fatigue as a risk when themselves or a colleague may be creating a fatigue-related hazard.
It’s also important to remember workers also have a responsibility to manage their own fatigue. Companies should encourage workers to learn the signs of fatigue and implement effective strategies for managing it. Safe Work Australia's fatigue management guide can help with this process.
