Comparative analysis of manual handling practices in kerbside collection of recyclable waste
Government targets for reducing waste going to landfill h ave led to an increase in the processing of domestic waste to reclaim recyclable materials. Manual sorting tasks can occur at the kerbside during waste collection and, if poorly designed, can introduce manual handling risks. This report describes research to better understand the kerbside collection and sorting methods currently employed by the waste industry and to determine how manual handling risks can best be reduced or controlled. Six detailed case studies are presented showing a range of vehicles and processes in operation. Manual...

Quebec Serve and Protect Low Back Pain Study: What About Mental Quality of Life?
Background As of now, the impact of low back pain (LBP) and its chronic state, chronic low back pain (CLBP), on mental health-related quality of life (HRQOL) has never been investigated among police officers. The present investigation aims at studying this relationship using a biopsychosocial model. Methods Between May and October 2014, a Web-based cross-sectional study was conducted among Quebec police officers (Quebec, Canada). Mental HRQOL was measured using the role emotional (RE) and the mental health (MH) domains of the SF-12v2 Health Survey. The impact of CLBP on mental HRQOL (as opposed...
Démarche multidisciplinaire appliquée à l’analyse d’une activité dans un environnement dynamique
La conduite de véhicules légers à La Poste pour la distribution du courrier et des colis Activité complexe différente de la conduite personnelle, la conduite professionnelle de véhicules légers prend une importance croissante dans le secteur de la livraison/messagerie confronté aux nouveaux modes de consommation. Peu étudiés, les risques pour la santé autres que les accidents de la route ont été approchés dans une étude exploratoire multidisciplinaire menée en collaboration avec le groupe...
Ergonomic and psychosocial factors and musculoskeletal complaints in public sector administration
A joint monitoring approach with analysis of association Administration entails a high level of computerization with multiple risk factors (including psychosocial and of ergonomic nature), affecting worker health and well-being. An ergonomics researcher supported by a senior ergonomist and guided by a domain specific checklist assessed physical ergonomics of an organization, including 96 administrative workers in the assessment. Unstructured observations and interviews to the workers were also done. Socio-demographic, musculoskeletal health and psychosocial job data was collected from a composite...
Développement du monoripage et conditions de travail
Depuis quelques années se développe la pratique du monoripage, c'est-à-dire la collecte des déchets par un équipage constitué d'un opérateur de collecte et d'un chauffeur. Une étude menée par l'INRS révèle que dans les conditions observées une telle collecte est physiquement plus intense que celle réalisée en biripage. Elle présente alors un risque plus élevé de troubles musculosquelettiques et une astreinte cardiaque excessive. L'étude montre qu'il...
One Size Does Not Fit All
When your safety and your life depends on it, you need your equipment to fit properly. This is especially true in the workplace. Improper fit may prevent workers from performing their job duties safely and effectively. If your respirator does not seal properly to your face, if your gloves are too big, if your seatbelt cannot buckle with your safety gear on . . . you get the picture. Anthropometry is the science of defining human body dimensions and physical characteristics. The National Institute for Occupational Safety and Health (NIOSH) conducts anthropometric research to prevent work-related...
Principes ergonomiques pour la conception des cabines de tri des déchets recyclables secs ménagers et assimilés issus des collectes sélectives
Le présent document définit les exigences à intégrer lors de la conception des cabines de tri manuel des déchets recyclables secs ménagers et assimilés issus des collectes sélectives. Ces exigences sont relatives aux structures, aux matériels, aux espaces et aux postes de travail nécessaires pour réaliser l'activité de séparation manuelle de ces déchets effectuée sur des tables de tri en cabine.

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...
Effect of firefighters' personal protective equipment on gait
The biomechanical experiment with eight male and four female firefighters demonstrates that the effect of adding essential equipment: turnout ensemble, self-contained breathing apparatus, and boots (leather and rubber boots), significantly restricts foot pronation. This finding is supported by a decrease in anterior-posterior and medial-lateral excursion of center of plantar pressure (COP) trajectory during walking. The accumulation of this equipment decreases COP velocity and increases foot-ground contact time and stride time, indicating increased gait instability. An increase in the flexing resistance...
Psychophysiological responses in experienced firefighters undertaking repeated self-contained breathing apparatus tasks
In order to safely and effectively extinguish fires and rescue life, firefighters are required to routinely wear self-contained breathing apparatus (SCBA), yet little is known about the specific physiological and psychological demands associated with repeated exposure to tasks that require SCBA. A total of 12 experienced firefighters took part in a series of commonly encountered SCBA activities: free search, guideline search and live firefighting tasks under room temperature (∼20°C) and extreme heat (∼180°C) conditions to assess changes in heart rate, blood pressure, mood, perceived...
The Healthy LifeWorks Project: The Effect of a Comprehensive Workplace Wellness Program on the Prevalence and Severity of Musculoskeletal Disorders in a Canadian Government Department
Objective : The purpose of this study was to determine the effect of a comprehensive workplace wellness program on the prevalence and severity of musculoskeletal disorders in a Canadian government department. Methods : The Healthy LifeWorks program was developed, implemented, and evaluated over a 4-year period. A total of 233 employees completed the Nordic Musculoskeletal Questionnaire before and after the program to determine the prevalence and severity of musculoskeletal disorders. Results : There was an approximately 10% decrease in the 12-month prevalence of musculoskeletal disorders, ranging...
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...
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...

Working conditions at recycling centres in Sweden
Physical and psychosocial work environment "The number of jobs at recycling centres are increasing, at the same time as there are indications of work environment problems. The aim of this paper was to investigate physical and psychosocial working conditions for employees at recycling centres in Sweden, to describe how they were perceived, to compare differences between subgroups, and further to identify proposals for improvement. Employees at 42 recycling centres (n = 122) responded a postal questionnaire. Of these 32 employees from 16 recycling centres were interviewed, as also their employer...
