Fatigue Risk Management System (FRMS)
Build Safer, Smarter Shift Operations with our Proven FRMS Solutions
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 railroads. 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.

THE CHALLENGE
Fatigue Risk Management System Design
CIRCADIAN® has nearly 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 organization's overall health and safety program to create a process that will continually monitor and mitigate fatigue risk.
7 Key characteristics of a successful Fatigue Risk Management System:
Science based – Supported by established peer-reviewed science
Data driven – Decisions based on collection and objective analysis of data related to workplace fatigue
Cooperative -- Designed together by all stakeholders, facilitated by a Fatigue Risk Management consultant
Fully Implemented – System-wide use of tools, systems, policies, procedures
Integrated -- Built into the corporate safety & health management systems
Continuously improved – Progressively reduces risk using feedback, evaluation & modification
Owned – Responsibility accepted by senior corporate leadership
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.
CIRCADIAN® has extensive experience as a Fatigue Risk Management consultant in implementing and reviewing FRMS in a wide-variety of industries. Our Gap Analysis tools will:
-
Numerically rate how well your organization meets required or recommended industry fatigue risk standards (e.g., ANSI-API RP 755 for Refining and Petrochemical Industries)
-
Develop recommendations, timelines, and accountability systems for bridging any gaps and improving your FRMS

CIRCADIAN® has broad international experience in FRMS evaluation, design, development, and implementation in many 24/7 industries:
Petrochemical & Refining
CIRCADIAN® served as a scientific consultant to the American Petroleum Institute as it developed the ANSI/API standard for fatigue risk management in the petrochemical and refining industries. Released in April 2010, ANSI RP-755 outlines the recommended practice for all stakeholders in the petroleum and petrochemical industries to understand, recognize, and mitigate fatigue in the workplace.
Aviation
CIRCADIAN® is working with diverse types of aviation carriers in the design, implementation, and auditing of FRMS. We have conducted a major study required by the US FAA (Federal Aviation Administration) on aircrew fatigue in ultra-long range (ULR) and long range flying with three airlines in collaboration with two universities.
Railroads
CIRCADIAN® developed the first FRMS in the Canada-US railroad industry, which has been the model for FRMS implementation throughout that industry.
Pipeline
Over the past few years, CIRCADIAN has worked with many Pipelines as they have implemented the fatigue mitigation portion of the PHMSA regulation for control room management.
