Take a Stand!
Amulti-component intervention aimed at reducing sitting time among office workers - A cluster randomized trial BACKGROUND: Prolonged sitting time has been associated with adverse health outcomes. Interventions at work may contribute to reduced sitting. The objective was to test if a multicomponent work-based intervention can reduce sitting time and the number of prolonged sitting periods (> 30 min), increase the number of sit-to-stand transitions and decrease waist circumference and body fat percentage among office workers. Primary outcomes were: change in sitting time, prolonged sitting periods...
Solutions visant l’amélioration des conditions de santé et de sécurité des poseurs de revêtements de sol
La pose de revêtement de sol se divise en différentes spécialités : céramique, bois et revêtement souple. C'est ce dernier secteur qui nous intéresse, soit la pose de tapis (accrochés ou collés; en rouleau, en tuiles) ou de matériaux résilients (linoléum, vinyle, caoutchouc, gazon synthétique, etc.). Le métier de poseur de revêtement de sol est exigeant sur le plan physique (manutention de rouleaux très lourds, travail à genou prolongé, épandage de colle sur de grandes...
Troubles musculosquelettiques et santé psychologique
Démarche de soutien aux activités de prise et de répartition des appels d'urgence 9-1-1 La présente étude constitue un prolongement des recherches antérieures ayant pour objectif de réduire les risques psychosociaux associés aux troubles musculosquelettiques et de santé psychologique chez les préposés des centres d'urgence 9-1-1. Elle se fonde plus précisément sur la précédente recherche (Toulouse et coll., 2011) dont les résultats suggéraient la nécessité...
Systems thinking applied to safety during manual handling tasks in the transport and storage industry
Injuries resulting from manual handling tasks represent an on-going problem for the transport and storage industry. This article describes an application of a systems theory-based approach, Rasmussen's (1997. Safety Science 27, 183), risk management framework, to the analysis of the factors influencing safety during manual handling activities in a freight handling organisation. Observations of manual handling activities, cognitive decision method interviews with workers (n=27) and interviews with managers (n=35) were used to gather information about three manual handling activities. Hierarchical...
An investigation into mechanical aids and automation for reducing the risks of repetitive handling tasks involving the upper limbs
The Health and Safety Executive (HSE) produced a document (INDG 398[1]) that provides practical advice on mechanical aids that reduce the risk of heavy manual handling. However, there is little information on the mechanisation and automation available to reduce upper limb disorder risks that can arise with repetitive handling (ie handling light loads at least every few seconds). HSE guidance 'Upper limb disorders in the workplace' suggests a hierarchical approach to risk reduction and asks 'can machinery do the highly repetitive functions and leave more varied jobs for the workers?'...
Ergonomic and Safety Climate Evaluation at a Brewery
HHE Program investigators evaluated concerns about musculoskeletal disorders on the can line and in the bottle depalletization areas at a brewery. Investigators determined that employees were at an increased risk for upper extremity work-related musculoskeletal disorders due to awkward postures, forceful exertions, and repetitive motions. Some employees reported that they felt uncomfortable reporting safety incidents or expressing their safety concerns. Investigators recommended that work areas be designed to have a working height between 27-62 inches and add rotating platforms to the height-adjustable...
Étude pour intervenir sur la réduction des troubles musculo-squelettiques et de santé psychologique dans les centres d’appels d’urgence 911 de la sécurité publique municipale
Une recherche multidisciplinaire a permis de mieux cerner les dimensions de la charge mentale en lien avec les TMS et les problèmes de santé psychologique des préposés des centres d’appels d’urgence 9-1-1, profession qui a été jusqu’à maintenant peu étudiée par les chercheurs. L’étude démontre que leur travail est loin d’être celui « d’un simple répartiteur d’appels » puisqu’ils doivent faire face avec efficacité à la gestion du flux...
Practical Demonstrations of Ergonomic Principles
Musculoskeletal disorders (MSDs) often involve the back, wrist, elbow, and/or shoulder, and occur when workers are exposed over time to MSD risk factors, such as awkward postures, forceful exertions, or repetitive motions. These exposures sometimes occur due to poorly designed workstations, tasks, and/or hand tools [Chaffin et al. 2006; Sanders and McCormick 1993; Silverstein et al. 1996, 1997]. Workers must understand the nature of MSD risk factors and how to avoid exposure to them. In a classroom setting, trainers may discuss ergonomic principles and show examples of MSD risk factors with photographs...

Ergonomics at materials recycling facilities
Conveyor belts are used in several industries to move materials. Using these systems in the workplace can reduce the risks of Musculoskeletal injury (MSD) by avoiding the need for excessive repetitive lifting and carrying. However, conveyor belt workstations should be properly designed to ensure that operators do not excessively lean, stoop, twist, or over-reach, since these repetitive movements can themselves lead to musculoskeletal injury. The workplace, size of the conveyor, type, through put and height of material, and how material is handled, are all factors to consider when assessing the...
Manual Handling Risks Grab Irish Authority's Attention
A new guidance document published by the Health and Safety Authority recommends ways to prevent back injuries and strains caused by handling heavy loads or lifting loads to an unsafe height. Ireland's Health and Safety Authority has posted a guidance document to help retail establishments prevent back injuries and strains that could result from manual handling of pallets, heavy boxes, and bulky consumer products at point of purchase, such as cases of bottled water. The agency noted that some work at retail establishments may involve a significant amount of physical activity, which can be hazardous...
Microcentrifuge Tube Ergonomics and the Required Force of Opening
A microtube that requires less force to open, coupled with a more ergonomic, perpendicular, and vertically extending tab, could reduce the occurrence of RSIs in laboratory personnel. Source : http://ohsonline.com/Articles/2010/07/01/Microcentrifuge-Tube-Ergonomics.aspx
Reducing Work-Related Musculoskeletal Disorders among Rodbusters
NIOSH evaluated reinforcing ironworkers' (rodbusters) exposures to risk factors for developing low-back and hand disorders when tying together reinforcing steel bars (rebar) on a freeway bridge. Rodbusters used three techniques to tie rebar together—a pliers and a tie wire wheel, a battery operated power tier (PT), and a PT with an extension handle (PTE). NIOSH found that using the PT and PTE reduced the rodbusters' exposures to risk factors for work-related low-back and hand-wrist disorders. In addition, power tying was twice as fast as than pliers tying. Source : http://www.cdc...
Study tests ways to increase uptake of ergonomic innovations
Ergonomic innovations in the construction sector could potentially reduce soft-tissue injuries or musculoskeletal disorders (MSDs), which represent 35 per cent of the sector's injuries in Ontario. However, introducing change is difficult because of the ever-changing nature of construction work. This study aimed to find out if “opinion leaders” — influential people from companies identified as respected trend-setters — might be a good way to promote new health and safety ideas within this complex sector. http://www.iwh.on.ca/highlights/study-tests-ways-to-increase-uptake...
Ergonomics case study: Car parts manufacturer realizes benefits of PE program
An Ontario manufacturer opened its doors to researchers who helped implement a participatory ergonomics (PE) program to improve the musculoskeletal health of workers. The company has since learned that the PE program saved it almost a quarter-of-a-million dollars — and in the most unexpected place. http://www.iwh.on.ca/at-work/57/pe-case-study
