Fatigue Hazard Analysis Risk Assessments

Fatigue Hazard Analysis (FHA) risk assessments can play a significant role in an organisation’s journey towards a comprehensive Fatigue Risk Management System. It is at the heart of our Risk-Based Approach to fatigue management.

Fatigue Hazard Analysis risk assessments are designed to establish a bridge between the Fatigue Risk Management System (FRMS) at an organisational level, and the procedures, activities and treatments required at an operational level.

The workshops draw on the knowledge of experienced staff to discuss fatigue related incidents that could, or have already occurred in the line of their day-to-day duties.

This interactive process is a recognised way to develop the appropriate controls and protection for tasks exposed or vulnerable to fatigue.

Each workshop is focused on a single task group of employees, such as pilots or nurses, and typically runs for between 1.5 – 2 days. All participants are encouraged to speak about their practical experiences of fatigue related risks, in order to achieve the following objectives:

  • Identify key operational tasks or day-to-day activities considered to present the greatest fatigue-related risks.
  • Create a Hazard Catalogue and assign risk likelihood and consequence ratings for the task hazards.
  • Derive a risk tolerance boundary based on the group’s collective view of the acceptability of varying levels of likelihood and consequence.
  • Develop risk improvement actions for the highest-risk hazards, and as a priority for hazards outside of the participants’ risk tolerance boundary.
  • Determine an hours of work Fatigue Tolerance Level (FTL) for the role, taking into account the fatigue-related risks assessed and other relevant information presented at the workshop.
  • Assist or support management in reducing fatigue-related risks.

Risk Management utilises the framework of AS/NZS ISO 31000:2009

An approved methodology

At the core of InterDynamics’ Fatigue Hazard Analysis (FHA) is the Zurich Risk Engineering methodology of Zurich Hazard Analysis (ZHA).  This is similar to, and supportive of the frameworks such as:

  •  AS/NZS ISO 31000:2009 (the Australian/New Zealand ISO standard for Risk management – Principles and guidelines);
  • CAN/CSA-Q850-1997; and
  • BS 6079-3:2000

The following software technologies may be used to support the process:

  1. FAID Quantum: Scientifically supported modelling software that analyses hours of work and provides a fatigue exposure assessment of work patterns.
  2. HAZAID: An interactive visual tool that standardises the FHA process. HAZAID prompts participants to catalogue hazards and assess fatigue risk associated with their roles and environment.
  3. GRAID FRMS: An organisational fatigue risk-grading tool, used to rate the adequacy of current and future safeguards, making up an organisation’s Fatigue Risk Management System (FRMS). GRAID reviews 24 different fatigue grading elements or risk factors, assigned each a varying level of importance. At the end of the review an overall grading is determined, providing feedback on the level of protection of the organisation’s FRMS against fatigue-related risks.

By undertaking the FHA risk assessment process, organisations are better able to meet, and potentially exceed current insurance industry standards for hazard analysis. This in turn makes them more attractive to insurers as a result of their lower organisational risk profile.
