New clues in prolonged sitting risks: tenure and obesity

Too much computerThe evidence base for the workplace risks from prolonged sitting is still only just being collated.  One of the latest research reports, in Preventive Medicine Reports, identifies two more clues to identifying these health hazards – the length of tenure and Body Mass Index (BMI) but the BMI is not what one would expect.

According to the article entitled “Office workers’ objectively assessed total and prolonged sitting time: Individual-level correlates and worksite variations“: Continue reading “New clues in prolonged sitting risks: tenure and obesity”

Evidence to support Stand Up, Sit Less, Move More

Office workers need to exercise more.  This is one of the simplest occupational health and safety (OHS) statements that can be made.  Whether one stands while answering a telephone, walks to a photocopier, have a walking meeting or take the stairs instead of the lift or escalator, you will be healthier by moving.  Too often this simple OHS message is confused by sellers of apps, products, furniture and training courses that promise success from a single intervention.  The way to avoid this is to look at the research and some recent Australian research into sedentary work is a useful reference in determining workplace safety interventions.

The research “A Cluster RCT to Reduce Office Worker’s Sitting Time: Impact on Activity Outcomes” has been written by a swag of researchers from around Australia and found that a:

“workplace-delivered multicomponent intervention was successful at reducing workplace and overall daily sitting time in both the short- and long- term.”

Stress advice that builds on what came before

In occupational health and safety (OHS), as in most things, it is possible to learn more from what is not said than what is said. Recently WorkSafe Victoria released a guidebook for employers on “Preventing and managing work-related stress”. Given the current community focus on stress, health and wellness, discussion of this document’s release has been quite muted. Part of the reason is that, in some ways, the guidebook does not fit with the contemporary health and wellness push.

WorkSafe has been publishing guidance on workplace stress and its subset, workplace bullying, for well over 20 years. It’s Stresswise publication  has been a de facto reference on the hazard and the workplace bullying changes initiated by the ACTU and implemented by WorkSafe Victoria, emerged from. ACTU surveys of its members specifically on workplace stress.

Part of the significance of investigating workplace stress is that the major causes are institutional, that is, the way businesses are managed rather than with the individual’s capacity to cope. It is here that the WorkSafe guidebook conflicts with the common approaches of the wellness advocates.

OHS benefits of motion sensors and contemporary anthropometry

Several years ago, at a workshop over the development of the next Australian National Strategy for occupational health and safety (OHS), participants were asked to forecast an issue that would appear or be useful in the next decade.  I suggested sub-dermal implants that would record or transmit real-time health data.  My suggestion was received with laughter and a little bit of horror.

The sub-dermal implants for OHS monitoring are yet to occur but the electronic collation of important health data has progressed to a high level of relevance. This not only involves measuring body stresses but the bodies themselves. Continue reading “OHS benefits of motion sensors and contemporary anthropometry”

Time to reassess our approaches to machinery safety

9781472450777.PPC_alternative mobilitesTalking about workplace safety and machine manufacturing is unfashionable, perhaps because Australia’s manufacturing capacity is in strong decline. And occupational health and safety (OHS) seems preoccupied at the moment with psychosocial hazards and wellness.  But one Australian researcher, Elizabeth Bluff, has undertaken an empirical study of safety attitudes, motivations and practice in the manufacturing and OHS regulatory sectors and produced a remarkable book that needs to be read by everyone involved with workplace health and safety.

Bluff writes

“In illuminating the mechanisms underlying manufacturers’ responses for machinery safety the research also makes wider conceptual and theoretical contributions.  It provides insights into knowledge and motivational factors as principal elements shaping firm performance for social and regulatory goals, and advances understanding of how these elements are constituted in the everyday operations of firms and their interactions with external actors.” (page 3)

Scissor Lifts and safety

Caulfield lights2 edited
digitally altered

Workers in scissor lifts often step on railings or overreach placing themselves at risk of falling.  These actions are contrary to the use of plant as usually recommended by  manufacturers and to the usual requirements in an occupational health and safety (OHS) management plan for working in the rail environment.

The actions in these photographs occurred on a Melbourne railway station and in an industry that this author has worked in for the last six years. Photographs never show the entire facts of a situation and there are many assumptions and what-if scenarios about which these photos could, and should, start discussions. The following discussion of occupational health and safety management issues focuses on the facts presented by the photos*.
