Chapter 4 - Conclusion

Beyond Level 1 controls

The software described in this document is intended help managers analyse work schedules for potential fatigue-related risk. However, using appropriate scheduling practices is only one component of an effective a fatigue risk management system. There will always be occasions when employees, intentionally or unintentionally, fail to get enough sleep. Even with sufficient sleep, fatigue-related symptoms can still occur if employees get poor quality sleep or have an undetected sleep disorder.

Under the five-level model of fatigue risk management that is at the heart of this toolbox, companies also need controls to determine whether employees are getting enough sleep (Level 2) and to detect fatigue-related symptoms on the job (Level 3). Organizations also need a process to deal with fatigue-related errors or incidents (Levels 4 and 5) to identify potential incidents, to learn from mistakes, and to check the effectiveness of previous levels of control.

A system with little or no hazard control beyond Level 1 scheduling tools is poorly defended against fatigue-related incidents.

Shared responsibility for managing fatigue

The responsibility for managing fatigue-related risk in an FRMS is shared between employers and employees. The Level 1 controls outlined in this document address the employer’s responsibility to manage schedule-related causes of fatigue. In Levels 2 to 5, employees are responsible for managing the causes of their own fatigue, and for reporting situations where they observe a fatigue-related risk. The employer is responsible for setting up clear and fair procedures that enable both groups to exercise their responsibilities. Policies and Procedures Development Guidelines (TP 14576E) provides further guidance as well as examples of policies and procedures for appropriate management of fatigue-related risk.
