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”.

26: Image 2 – The CSRA provided the AC/DC framework, being alternative controls / direct controls. Direct Controls are specifically designed to mitigate energy, whereas alternative controls are a placeholder for direct controls and target error, or control support activities.
The CSRA also provides rules for the use of AC/DC.
27: Image 3 – How dangerous is sleepiness compared to alcohol intoxication? This study found approximately 24 hours of wakefulness was equivalent to 0.05% blood alcohol intoxication in cognitive testing.
