What’s the link between shift work and safety incidents? This systematic review of 24 studies explored the links. Extracts: · It’s estimated that 10-30% of the workforce in industrialised societies engage in non-standard work / shift work · Overall, they found “an increased risk of safety incidents during or after night shifts” · “Accumulated exposure to evening or… Continue reading Association of non-standard working time arrangements with safety incidents: a systematic review

Safe As week in review: 25, 26, 27 – value of high-risk procedures, direct risk controls, and fatigue vs alcohol intoxication
Safe As week in review: 25: Image 1 – This study found more experienced workers more likely to depart from procedures, and “adherence to procedures is often motivated by potential liability issues instead of genuine concerns for safety in organizations and many deviations from procedures were due to pressure from immediate supervisors”.

Safety climate and fatigue have differential impacts on safety issues: Safety climate, fatigue, and safety issues
This study explored the links between safety climate, fatigue and several safety issues (actual safety incidents reported, near-misses experienced, safety underreporting). >11k navy personnel were surveyed (survey/self-declared, so consider limitations). Key findings: · “Safety climate affected underreporting the most, followed by likelihood of experiencing a near-miss, but had the weakest impact on actual safety reporting” · “Conversely,… Continue reading Safety climate and fatigue have differential impacts on safety issues: Safety climate, fatigue, and safety issues
Insidious Safety Threat of Fatigue: Investigating Construction Workers’ Risk of Accident Due to Fatigue
This was really interesting. It studied the impact of self-assessed fatigue on hazard recognition and safety risk perception in construction. Fatigue is a ubiquitous phenomenon and among construction workers is said to be no different. It’s been implicated in a range of safety and performance implications. 135 construction workers were recruited to participate in the… Continue reading Insidious Safety Threat of Fatigue: Investigating Construction Workers’ Risk of Accident Due to Fatigue
Fatigue impairment (sustained wakefulness) similar to BAC 0.05% impairments in reaction time
Extended wakefulness (24h) equivalent to a 0.05% Blood Alcohol Concentration (BAC), so this study found. One of several studies which compared sustained wakefulness and different alcohol intoxication levels on cognitive performance, however this study found the earlier studies overestimated the effects. 40 adults were kept awake for 24h and tested on a simple cognitive performance… Continue reading Fatigue impairment (sustained wakefulness) similar to BAC 0.05% impairments in reaction time
Night shift work and indicators of cardiovascular risk. A systematic review and meta-analysis
Night shift work linked to various indices of cardiovascular disease (CVD) risk in this systematic review and meta-analysis. 81 studies were evaluated. Extracts: · “Dose-dependent effects were reported for these cardiovascular risk indicators, suggesting that the intensity and duration of night shift work contribute to risk of CVD” · “This systematic review reports moderate-confidence evidence for inflammation,… Continue reading Night shift work and indicators of cardiovascular risk.

Safety incidents associated with extended working hours. A systematic review and meta-analysis
This meta-analysis evaluated whether extended working hours is associated with work injury (either during or after work). 22 studies were included. This study didn’t find significant evidence for all of the expected links found in other studies (e.g. weak or no association between working overtime on incidents), and this is likely a result of their… Continue reading Safety incidents associated with extended working hours.

1912 article discussing the role of fatigue in industrial accidents and arguing against ‘carelessness’ as an “ultimate cause”
This was an interesting article from 1912 highlighting the role that fatigue has in industrial accidents. Also challenges ‘carelessness’, saying it doesn’t account for the effects of fatigue. While scientific knowledge has progressed over the century, it’s cool how well they articulated the issue. · Image 1 top panel shows a breakdown of accidents per time… Continue reading 1912 article discussing the role of fatigue in industrial accidents and arguing against ‘carelessness’ as an “ultimate cause”
