Issue 18 – March 2012

Dear Reader,

Having been the editor of Focus and Fatigue, for 5 years it is timely to review the reason that FaidSafe exists and why it is offered as the global benchmark for services assisting the implementation of fatigue safe systems.
Many organisations faced with the challenge of managing fatigue can easily become daunted by the prospect. Impairment associated with fatigue can be difficult to detect, and harder still, is judging the level of impairment that could present a danger. Added to the complexity of individual differences in experiencing fatigue is the context for individuals (e.g. job type, activities, environment, time of day, etc.) and the degree to which this is vulnerable to fatigue.

Given the diverse factors needed to be taken into account in managing work-related fatigue, a risk-based approach that gives consideration to models like James Reason’s ‘Swiss Cheese’ model is often recommended. The Defences-in-Depth model (Dawson & McCulloch, Sleep Med. Rev. 2005) applies James Reason’s model to the fatigue context, targeting prevention through a series of barriers, safeguards, and defences. InterDynamics has included these concepts and ideas in its risk-based approach to managing fatigue (FaidSafe), summarised in this diagram.

Founded on staff engagement and consultation, shared responsibility, and effective risk management, the FaidSafe methodology represents a risk-based approach to managing fatigue that targets improved safety and performance as key outcomes.

FaidSafe services are modular in nature, and exist to assist organisations wherever they are at along the journey of fatigue risk management.

Products and services include:

  • Organisational FRMS benchmarking and grading systems
  • Fatigue surveys
  • Managing fatigue training for employees
  • Facilitation of Fatigue Hazard Analysis risk assessments
  • Training in the context and use of FAID
  • Change management support
  • Assistance in incident investigation
  • Hours of Work fatigue diagnostic reports (planned and actual)
  • Data analysis
  • Fatigue management policy, procedure and FRMS reviews, and
  • The provision of decision making support tools (such as the internationally recognised and scientifically supported bio-mathematical model FAID) to assist in the identification and treatment of fatigue related risks.

NEWSFLASH:FAID v2.1 has just been released. See further down in newsletter for details and to enquire how to receive your upgrade!

The FaidSafe alliance consists of fatigue management professionals from around the globe that believe in using scientifically valid tools and best-practice methodologies in the management of fatigue from a risk perspective.

We hope that you will find this edition useful as we explore the importance of understanding bio-mathematical models and their appropriate use.If you wish to unsubscribe from our newsletter, please click the unsubscribe link at the bottom of this email. Thank you for your continued support!

Understanding bio-mathematical models

Adam Fletcher, PhD, MAICD and Richard Yates, FRAeS, MILT

When it comes to managing fatigue-related risk, regulators and businesses have been (and are increasingly) using bio-mathematical models to assist them in predicting the fatigue levels associated with hours of work. These predictions are often used in conjunction with other factors such as workload, commuting and on-call requirements. Such bio-mathematical models, including FAID®, have generally been developed after extensive scientific research, validation and industry testing. However, some available models have not undergone any sort of rigorous process.

Practical use of bio-mathematical models

Peter Page, Managing Director InterDynamics Pty Ltd – Developers of FAID®

For the past twenty years InterDynamics has built and supplied software simulation models and decision support tools to assist managers, analysts and operators understand and manage their business operations. Over this time we have learned much about the practical implementation of models as decision support tools. This experience has also exposed us to common misunderstandings, and at times inappropriate use of models.

New model Work Health and Safety Act – Australia

Tu Mushenko, InterDynamics FaidSafe Consultant

In Australia, one key challenge for 2012, is ensuring compliance with the new model Work Health & Safety Act (the WHS Act) as it is ratified around the country. The new Act has lifted the mode of addressing work health and safety, including fatigue management, to a more proactive and practical approach underpinned by effective risk management.

In the next edition… we will explore how to get the most out of your risk assessment process, and in particular when considering the challenges presented by the fatigue context.

Metrorail employees are overworked – five year study…

Alia E. Dastagir – dcist News November 13, 2011

New report finds Metrorail employees are overworked and five year study found that Metrorail employees in safety critical jobs are working longer hours which could lead to fatigue and accidents.

Shhh! The kids need more sleep – or do they?

Michael Smith, North American Correspondent, MedPage Today, February 13, 2012

Kids don’t get the recommended amount of sleep — and they never have.
That’s the conclusion of Australian researchers who tracked changes in sleep recommendations, and what was known about actual sleep time, over more than a century.

Workers are dying to get home from the coalface

Paul Cleary, The Australian, July 23, 2011

Australia’s road transport industry operates under a stringent regulatory regime that ensures no one drives more than 12 hours a day. But the same rules don’t apply to mine workers who drive for 12 hours on mine sites, then drive long distances on public roads to return home.

Sleep disorders costing

Ashley Hall – ABC News, February 2,  2012

New research has found sleep disorders cost the Australian economy more than $5 billion a year in health care and indirect costs.

FAID® v2.1 Released

InterDynamics is proud to release v2.1 of it’s scientifically valid and operationally tested bio-mathematical model Fatigue Audit InterDyne® (FAID).

FAID Version 2.1 provides a refined experience of use, incorporating many of the suggestions received by users (as well as some extra features we’ve thought of ourselves). We hope you will find the improvements in FAID v2.1 of benefit in terms of speed, refinement of features, and ease-of-use. FAID analysis is a valuable means of identifying indicative fatigue exposure based on hours of work, and in particular for comparing roster patterns on this basis. However, other factors such as lifestyle, predictability, working environment and conditions, employee experience, etc should also be considered in determining the most appropriate hours of work.

As always it is good to remember that the use of FAID, in and of itself, is not a Fatigue Risk Management System, but one valuable tool in assessing indicative Hours of Work related fatigue, within the wider range of risk management activities and treatments required.

Full details of what is new in FAID v2.1 can be found here.

Contact us at if you would like to to upgrade your existing version of FAID to version v2.1 and take advantage of the new enhancements, or to discuss other aspects of FRMS that we can assist with.
