Co-exposures to physical and psychosocial work factors increase the occurrence of workplace injuries among French care workers
Psychosocial and physical workplace exposures found to be co-related in workplace injury (WI), according to this study. It’s one of heaps of studies highlighting the interactions between psychosocial factors and physical and psychological injury. E.g. Physical exposures were on their own were not great predictors of self-declared injury, and it was the interactions that best… Continue reading Co-exposures to physical and psychosocial work factors increase the occurrence of workplace injuries among French care workers

Findings: · Inadequate sleep was defined as fewer than 7 h per night · 1/3 of adults regularly experience insufficient sleep which are “driven by lifestyle factors deeply rooted in modern society” · Chronic sleep deprivation has been linked… Continue reading Imbalanced sleep increases mortality risk by 14–34%: a meta-analysis
Human Error: Trick or Treat?
This 2007 chapter from Hollnagel unpacked whether we really need the concept of “human error” (HE). It’s a whole chapter, so I’ve skipped HEAPS. Tl;dr according to Hollnagel: · “there is no need of a theory of “human error” because the observed discrepancies in performance should be explained by a theory of normal performance rather… Continue reading Human Error: Trick or Treat?

What Control Measures Should I Use? Applying the Total Worker Health Hierarchy of Controls to Manage Workplace Fatigue
This new paper from Drew Dawson and others reconceptualised fatigue risk management within Total Worker Health (TWH) Hierarchy of Controls (HOC). THW HOC works as an extension to the traditional HOC, and “presents strategies in order of effectiveness, ranging from “eliminate,” “substitute,” “redesign,” “educate,” and “encourage” categories” They say that while is mostly associated with… Continue reading What Control Measures Should I Use?

Safety Management Systems may struggle with psychosocial factors and other complex phenomena
Certified safety management systems (OHSM) may struggle with complex, multi-factorial matters, like psychosocial safety. Extracts: · The OHSM “does not necessarily tackle the most urgent work environment issues and may exclude important aspects of the work environment such as psychosocial factors” · “some [OHSM] approaches may be ill-equipped to tackle complex sociotechnical issues and psychosocial matters, and… Continue reading Safety Management Systems may struggle with psychosocial factors and other complex phenomena
