Fatigue Management / Fatigue Risk Assessment

Fatigue is defined as a decreased capacity to perform mental or physical work as a result of inadequate restorative sleep. It is also influenced by circadian factors and prior wakefulness. Fatigue builds in the body over time, and the only way to rid the body of fatigue is through restorative sleep. Alertness, the intermediate state between wakefulness and sleep, fluctuates between different levels ranging from alert to drowsy. The more fatigue in the body, the more frequent and significant the drowsiness episodes, which elevates the risk of incidents. 

Today, 24-hour operations are necessary to meet the demands of an industrialized global economy, but it comes with unique physiological challenges that can impact fatigue, compromised alertness, and reduce performance. The consequences are operational, societal, and personal. Waking hours easily add up when shift length, overtime, commuting, recreation and family life are accounted for, and all at the expense of sleep. Science has demonstrated that tired workers are impaired workers. They are forgetful, more confrontational, have trouble with complex decision making, are slower to react, use flawed logic and demonstrate poor judgment. Errors are more frequent, injuries rise and overall work performance suffers. And that affects the bottom line. 

Fatigue is a complex issue and therefore requires a formal management system that is rooted in science and driven by objective analysis of data. It requires collaboration and cooperation with all stakeholders and respects family concerns. Finally, it requires senior leadership to accept responsibility and accountability as owners of the system. From lifestyle training to shift design, risk assessments to lighting strategies, policy guidance to supervisory support, our human factors experts understand that there is no easy fix, and we’ll help you determine the best and most cost-effective controls to identify and mitigate risk. Do you know where your fatigue-related risks are? Do you have the right strategies in place? If you have questions, we have the answers. 

If you're worried about the impact of fatigue at the job site, SIX Safety can:

  • Complete a Needs Assessment/Gap Analysis (NAGA)
  • Complete fatigue hazard identification and risk assessment of current job activities and shift schedules
  • Assess incidents for fatigue as a contributing factor
  • Determine the need for fatigue or alertness detection monitoring systems

We will identify hazards using a variety of tools ranging from an examination of lagging indicators and current fatigue management practices to consideration of cognitive and physical demands of the job, environmental impacts, and of course, workforce demographics.

As in everything we do, SIX Safety's fatigue risk assessment process is aligned with regulatory bodies, national and international standards associations, and current human factors principles.


Fatigue Management Program Design


Consider the following:


  • Has fatigue been identified as a contributing factor to incidents in your organization?
  • Are you in compliance with provincial / federal acts and regulations related to fatigue?
  • Are you in sync with CSA / ISO / NIOSH standards and industry recommended practices?
  • What are employees saying about fatigue and their schedules?

An effective, systematic approach to fatigue management requires an organization to implement operational and preventative measures. It also requires employees to personally adopt a shift worker's lifestyle using proven strategies--yes, shift work is a lifestyle, not a schedule.

Based on consultations with stakeholders and the results of a fatigue risk assessment, the right fatigue management program can be developed for your organization.


By building a solid fatigue management program from the foundation up, you will:


  • Reduce errors
  • Reduce worker turnover
  • Reduce liabilities
  • Improve quality of work
  • Increase both personal and organizational health, safety, and performance
  • Increase overall quality of life for workers and their families
