Sleep, Alertness & Fatigue Accident Risk Performance Health/Social Big consequences if we dont get it right

Fatigue Risk Management Models Restricted Hours Industrially Negotiated Largely Ineffective at FRM Traditional FRM Multiple Controls Red Flag System Identify Risk Manage Risk Proposed CSG FRM

Slide 5

Managing Fatigue: Its All About Sleep! Sleep Opportunity (Work Hours) Actual Sleep Symptoms and Behaviours Errors & Near-misses INCIDENTS Dawson & McCulloch (2005), Sleep Medicine Reviews, 9 (5), 365-380

Slide 6

Sleep Opportunity: Planned Work Hours Guidelines Max work hours in a 24-h period 12 hours Min break length between shifts 10 hours Max number of shifts worked in a row 15 shifts Min number of days off per 28 days 7 Min breaks within shifts 30 minutes every 4 hrs Window of Work 0600-2200* * Any work should be conducted within these hours, but is not expected to last for the duration

Slide 7

Sleep Opportunity: Actual Work Hours Guidelines Max work hours in a 24-h period (once off basis) 16 hours Max work hours in a 24-h period (for 2 or more days in a row) 14 hours Min break length between shifts 8 hours Max number of shifts worked in a row 21 shifts Min number of days off per 28 days 7 Min breaks within shifts 30 minutes every 5 hrs

Slide 8

Summarising Hours of Work Guidelines Planned work hours Red flag Fatigue Management Plan Consider impact on safety critical tasks Fatigue modelling to maximise sleep opportunity & recovery Actual work hours Avoid excursions from planned work hours Where required, stay within the prescribed limits Business/safety requirement to exceed actual work hours limits only with individuals consent, and with formally documented strategies in place Work Environment/Work Tasks

Actual Sleep: Personal Fitness for Work Caffeine (mg/head/day) 19101930195019701990 Sleep (hrs) 10 9 8 7 500 400 300 200 100 6

Slide 11

Actual Sleep: Personal Fitness for Work Minimum of 6 hours sleep every 24 hours How do we achieve this? Training & education Culture & FFW expectations Encourage self-reporting for trend analysis Challenges Perceptions of fatigue as a threat Travel to work & start shift Short changes Sleep disorders

Slide 12

Symptoms & Behaviours: Personal Fitness for Work Physical Yawning Heavy Limbs Appearance Headache/Nausea Sore Eyes Poor Coordination Slow Reaction Speed Extreme Drowsiness Heavy Eyelids Micro-sleeps Falling Asleep Mental Poor Concentration Disorganisation Easily Distracted Poor Communication Situational Awareness Poor Info Processing Poor Memory Poor Decision Making Risk Taking Behaviour Errors Emotional Quiet and Withdrawn Lack of Motivation Increased Stress Levels Mood Change Decreased Tolerance Irritability Uncontrolled Temper Aggression

Slide 13

Symptoms & Behaviours: Personal Fitness for Work Active intervention for symptoms of moderate or high severity How do we achieve this? Training & education Culture & FFW expectations Encourage self- & peer-reporting for trend analysis Challenges Perceptions of fatigue as a threat Perceptions of dobbing Flexibility with mitigation strategies

Slide 14

Risk Identification Risk Mitigation Have rostered hours been exceeded? ID Has the individual obtained at least 6hrs sleep in the last 24hrs? ID Is the individual experiencing fatigue-related symptoms or behaviours? ID What safety critical tasks is this individual performing? What could potentially go wrong if theyre tired? Mitigation Should this individual continue with planned work? What can be done to reduce the likelihood of error? Mitigation

Slide 15

Incident Investigation Fatigue is an unrecognised contributor to many workplace incidents The more info we can gather about the nature & consequence of fatigue, the better we can manage it Investigations should consider: Work history Number of consecutive night shifts Breaks during the shift Nature & demands of work tasks & work environment Travel time before and after shifts Sleep history of the individual(s) involved Medical issues that may contribute to fatigue (e.g. sleep disorders) Observed fatigue-related symptoms & behaviours Substances likely to cause drowsiness or prevent sleep
