Fatigue Risk Management System (FRMS)

Fatigue Risk Management Systems (FRMS) are now the globally-accepted standard for managing the risk of employee fatigue in safety-sensitive businesses, including aviation, petrochemicals, and railways. New laws, regulations, and ANSI standards continue to be published that require more and more companies in a variety of industries to design and implement an FRMS.

How to Design an Effective FRMS

CIRCADIAN has over 30 years of experience in developing and implementing fatigue risk management systems (FRMS).


An FRMS is a data-driven, risk-informed, safety performance-based proactive program to mitigate the risks of fatigue in 24/7 operations. An FRMS fits within an organisation’s overall health and safety program to create a process that will continually monitor and mitigate fatigue risk.

FRMS Gap Analyses, Assessments & Audits

CIRCADIAN’s expert gap analysis tools can help your company evaluate its current needs for fatigue mitigation, either to establish a new state-of the-art FRMS or to improve a system already implemented.


Our Gap Analysis tools will:

  • Numerically rate how well your organisation meets required or recommended industry fatigue risk standards (e.g., ANSI-API RP 755 for Refining and Petrochemical Industries)
  • Develop recommendations, times lines, and accountability systems for bridging any gaps and improving your FRMS

Comprehensive FRMS Tool Kits

Tools and services that address every component of a successful fatigue risk management system include:

  • Staffing and Hours of Service compliance
  • Scheduling and fatigue risk modelling
  • Education and training
  • Risk assessments
  • Accident and incident investigation

To successfully manage fatigue risk, five key defences are required. A successful FRMS offers a systematic defence of each risk and involving specific tools to mitigate it.
