Work-related Musculoskeletal Disorders, a tri-sector exploration
High rates of WRMSD-related sick leave put pressure on employers and businesses, hitting their bottom lines and potentially leading to understaffing, reduced productivity and lower staff morale. Directly affected workers not only suffer pain but also consequences that can be felt across their working, home and social lives. The construction, healthcare and transportation and storage industries were selected as the focus of this research because they have significantly higher rates of WRMSDs compared with the average rate for all industry. Qualitative research was commissioned to: - Explore what...
Effectiveness of a vacuum lifting system in reducing spinal load during airline baggage handling
Information on spinal loading for using lift assist systems for airport baggage handling is lacking. We conducted a laboratory study to evaluate a vacuum lift system for reducing lumbar spinal loads during baggage loading/unloading tasks. Ten subjects performed the tasks using the industry average baggage weight of 14.5?kg on a typical two-shelved baggage cart with or without using the lift system (i.e. lifting technique). Repeated measures analysis of variance (2 tasks × 2 shelf heights x 2 techniques) was used. Spinal loads were estimated by an electromyography-driven biomechanical model...
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...
Anthropometric Study of U.S. Truck Drivers
Methods, Summary Statistics, and Multivariate Accommodation Models Since up-to-date anthropometric data, which plays an important role in improving ergonomic design of truck cabs, has not been collected for decades, NIOSH launched the first-ever federal anthropometric study of U.S. truck drivers. This document summarizes the results of the study that, we hope, will be used by truck manufacturers, parts suppliers, transportation researchers, fleet managers, and other interested parties for decades to come.

Factors in the design of order picking systems that influence manual handling practices
Order picking can be defined as the retrieval of stock keeping units from a warehouse according to a pick list generated from a customer order prior to the despatch of the completed order to the customer. There is a variety of order picking systems that are used in warehouses and distribution centres and the choice of system will determine the amount and type of manual handling that occurs within those locations. In order to understand the factors that influence the design of order picking systems a literature review was undertaken and telephone interviews were conducted with six industry stakeholders...
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...
Vibrations, exiguïté, faible marge de manoeuvre
Comment améliorer le poste de conduite du métro de Montréal? Ce document est destiné aux intervenants en santé et en sécurité du travail, aux ergonomes, aux ingénieurs et à toute personne concernée par l'amélioration d'un poste de travail dans un contexte de faible marge de manoeuvre. Il décrit sommairement tant la démarche technique que la collaboration qui ont permis d'améliorer le poste de conduite du métro de Montréal dont le siège, l'espace restreint et les...
A review of workplace transport safety and HSE commissioned work on manual handling and delivery of goods
The Heath and Safety Laboratory (HSL) was approached by the Health and Safety Executive (HSE) Workplace Transport programme to carry out a general literature review in the area of workplace transport safety. After discussions to establish the scope of the work, the project team identified that, for completeness of information, a review concerning the related aspect of manual handling and delivery of goods should also be included. This report presents the results of the literature review in the areas of a) workplace transport safety, and b) manual handling and delivery of goods. Source : http:/...
Développement d’un prototype de siège pour opérateur de métro dans un contexte où l’espace est très restreint
Cette étude porte sur le développement d'un prototype de siège d'opérateur de métro permettant d'atténuer les vibrations et d'améliorer le confort, tout en convenant à l'espace très restreint de la loge de conduite. Le siège actuellement utilisé (strapontin) et conçu il y a une trentaine d'années, s'avère insatisfaisant : il est de confection rudimentaire et amplifie les vibrations. Cette étude fait suite à l'analyse ergonomique et vibratoire du poste d'opérateur...
Truck Driver Demographics and the Risk of Musculoskeletal Injuries
Commercial truck drivers face the risk of injury not only from accidents on the road, but also from the physical toll of sitting in and operating the vehicle. According to a recent Atlas Ergonomics study, long hours behind the wheel put certain drivers at a higher risk of developing musculoskeletal injuries.
