The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is a set of recommendations by the United Nations, first issued in 2003 as a communication tool for the sound management of chemicals, comprising harmonized classification criteria for physical, health and environmental hazards, a unified format for material safety data sheets (MSDS), and labeling elements includi...

Musculoskeletal disorders (MSDs) are a common health problem throughout the world and a major cause of disability among the work force. Assessment of exposure level to MSD risk factors can be an appropriate base for planning and implementing interventional ergonomic programs in the workplace. This study was conducted among workers of an Iranian rubber factory with the objectives of (a) determin...

BACKGROUND Musculoskeletal disorders (MSDs) are among the most common pathologies in the general population. However, research into the prevalence of upper arm MSDs is hampered by a lack of uniformity in case definition, and by the absence of a gold standard for measurement. Furthermore, some sectors of the population have benefited from extensive research whilst others have largely been ignore...

BACKGROUND Work-related Musculoskeletal Disorders (MSDs) affect the well-being of workers. Unfortunately, user requirements for design to reduce workplace risk factors for MSDs are not always effectively communicated to designers creating a mismatch between the user requirements and what is ultimately produced. OBJECTIVE To understand the views of practitioners of design and ergonomics regard...

Excessive demands on Operation Room (OR) nurses may result in high rates of Musculoskeletal Disorders (MSDs). This study was conducted among Shiraz city hospital OR nurses to determine the prevalence of MSDs and to examine the relationship between perceived demands and reported MSDs. In this cross-sectional study, 375 OR nurses participated (response rate: 80%). The Nordic Musculoskeletal Disor...

Our aim in this paper is to extend the matched subspace detectors (MSDs) of [1–3] to the detection of stochastic signals. In [1–3] the signal to be detected was assumed to be placed deterministically at an unknown location in a known signal subspace. The basis for the subspace was irrelevant. In this paper the signal is assumed to be placed randomly at an unknown location in a known subspace. I...

BACKGROUND Musculoskeletal disorders (MSDs) are potential sources of morbidity in hair restoration surgeons (HRS). This is particularly true for those who perform follicular unit extraction (FUE). OBJECTIVE To describe the nature, prevalence, and extent of ergonomic or work-related MSDs among HRS. METHODS & MATERIALS A survey regarding MSDs was e-mailed to 100 HRS. RESULTS Thirty-eight HR...

BACKGROUND Dentists are susceptible to Musculoskeletal Disorders (MSDs) due to prolonged static postures. To prevent MSDs, working postures of dental students should be assessed and corrected in early career life. OBJECTIVE This study estimated the risk of developing musculoskeletal disorders in dental students using Rapid Upper Limb Assessment (RULA) tool. METHODS A number of 103 undergrad...
