Fatigue Risk Calculator Template

A Fatigue Risk Calculator uses a scoring system that provides a structured way of assessing fatigue levels based on measurable indicators, such as sleep quality, work schedule, and work environment. This scoring system helps supervisors make decisions and recommendations. The scores are grouped into ranges that indicate the levels of fatigue, from good (well-rested) to certainly fatigued (severe signs of fatigue).

1-3: Good

Workers who score 1-3 on the Fatigue Risk Calculator are in excellent condition. It means that these individuals are well-rested, functioning optimally, and fit for duty. This score should be the ideal target for workers to maintain, as it reduces the likelihood of fatigue-related risks and contributes to a safer and more productive work environment.

4-6: Unlikely Fatigued

This range suggests that the worker is exhibiting signs of tiredness, such as slight drowsiness or reduced focus, but the level of alertness remains at acceptable levels, and the worker is generally fit for work. However, it is still vital to monitor for any changes, especially on long shifts or physically demanding tasks. Letting the employee take breaks can mitigate the progress of fatigue.

7-9: Possibly Fatigued

A score in this range may indicate that signs of fatigue are already manifesting. The worker may begin to lose focus, have a slower reaction time, and decrease his levels of alertness. While the worker may be able to do his tasks, there is an increased risk of lapses in judgment and errors. During this stage, it is important for the team lead or supervisor to provide control measures that could intervene in fatigue buildup.

10-12: Likely Fatigued

Getting these scores on the Fatigue Risk Calculator suggests that workers are experiencing significant levels of fatigue that can impair their mental and physical performance. These effects can pose a serious risk, especially in high-risk environments where alertness and precision are critical to safety. Supervisors should treat this level of fatigue as a warning sign that could end poorly if not addressed properly.

13 and above

Certainly fatigued: Scoring 13 and above indicates that the worker is experiencing severe levels of fatigue. At this stage, the worker is no longer fit to work. Forcing him to work at these levels can pose an immediate threat to personal safety, coworker safety, and operational integrity. Supervisors should immediately remove any individual experiencing these levels of fatigue from duty and advise them to rest and recover. Supervisors should also take this as a sign to review and revise schedules, workloads, and fatigue management protocols.
