HAZAID Hazard Cataloguing and Risk Assessment Tool is used to record the Fatigue Hazard Analysis (FHA) risk assessment information gathered during a FHA workshop. It is highly visual and interactive, and is used to ensure a high standard is maintained for information captured during the workshop process.

Fatigue Hazard Scenarios are defined by:

  • Tasks (WHAT / WHERE?) – e.g. operation of equipment.
  • Triggers (HOW / WHY?) which include errors caused by one or more fatigue impairments (e.g. communication, situation assessment / mental models / memory / performance insight and any other type of trigger (e.g. weather, equipment defects, lack of fuel, schedule recovery)
  • Effects (HOW BAD – HOW BIG, HOW OFTEN?)

Risk assessment (severity/probability) of each scenario is then determined by:

  • Reports of accident and incidents that are part of the organisations’ safety management system;
  • Details and statistics of accidents and incidents that are available from Safety Authorities (such as a Civil Aviation Safety Authority) who have responsibility for industry wide safety; and
  • Details and statistics of accidents and incidents for the organisations’ industry that are available from the organisations’ insurer.

Existing Controls are noted and the effect on the organisation as a result of a scenario is then determined and noted, e.g.

  • Increased scrutiny by safety authorities and insurers;
  • Down-time due to equipment malfunction caused by user error; or
  • Poor market image.
Individual hazard data input

During the FHA, HAZAID is used to establish a catalogue of hazards, and Consequences and Probability are identified.

HAZAID Task Risk Matrix

Once the hazards have been entered, HAZAID offers a Task Risk Matrix identifying which Hazards have an unacceptable consequence based on the probability of the occurence

By loading a FAID Quantum Hours of Work dataset, it is then possible to view the Fatigue Matrix based on selected Fatigue Tolerance Levels.

At the end of the FHA process, improvement actions are assigned to hazards which are considered to have unacceptable consequences to the organisation.  During this process, implementation dates can be set and costs can be allocated to the improvement action.  The above figure shows a comparison between the Task Risk Matrix and the Improvement Actions Task Risk Matrix

Outcomes of a Fatigue Hazard Analysis (FHA) using HAZAID include:

  • Setting of appropriate benchmark figures for FAID Score and KSS Tolerance Levels, and Target Compliance percentages, for specific tasks or roles
  • Increased employee engagement and contribution in the identification of acceptable fatigue related risk exposure levels, and other necessary controls that can inform the development and continuous improvement of the Fatigue Management Plan; leading to the reduction of overall fatigue-related risk, and greater acceptance and effectiveness of risk improvement actions (including the use of FAID Quantum)
  • Treatments/controls that are transparent, agreed & specific to each team/group/department
  • Acceptable & unacceptable fatigue-related risks identified and made clear to all
  • Security of knowing that the Fatigue Risk Management component of the Safety Management System is being based on data from objective analysis & organisational experience
  • Documented records of outcomes and the level of rigour applied to determining tolerable levels of fatigue related risk exposure and recommended treatments
  • Prioritisation for risk reduction investments
  • Benchmark data for future review of fatigue-related exposures and controls
  • Fatigue Risk Management controls that are transparent, agreed and understood at all levels, and sit above regulatory compliance-based systems
  • Increased employee confidence in the ongoing commitment by the organisation to reducing fatigue-related risk through regular reviews and best practice processes
  • Improved knowledge and communication through information about fatigue-related risk & scientific facts of sleep deprivation being available to all
  • Consistent, repeatable, fatigue-related risk assessment & documentation processes
