In Ontario, asbestos remediation requires full-body protective coveralls, head coverings, and other personal protective equipment such as respirators, gloves, and boots. These types of protective clothing can put workers at increased risk of developing heat-related illnesses. The Insulators Labour-Management Health and Safety Committee, in partnership with IHSA, has developed a Health and Safety Advisory on this issue Source : http://www.ihsa.ca/images/pfiles/532_W152.pdf
L’Institut national du cancer (INCa) met en ligne un guide de ressources documentaires sur la prévention primaire des cancers professionnels : Cancers Pro Doc. Il propose une sélection de documents publiés au cours des dix dernières années. Ceux-ci proviennent de sites institutionnels ou d’organismes reconnus (instituts de recherche, ministères, agences, organismes internationaux etc.).

The purpose of this study was to examine 1) wildfire fighters' ability to consume the prescribed fluid volume (1200 mL h−1), 2) the effect of fluid intake on plasma sodium and hydration, and 3) the effect of fluid intake on firefighters' heart rate, core temperature and activity during emergency suppression shifts. Methods : Thirty-four firefighters were divided into ad libitum (AD, n = 17) and prescribed (PR, n = 17) drinking groups. Results : PR drinkers did not meet the prescribed fluid target, yet consumed over double the volume of AD drinkers. No differences between groups in...
Générées par de multiples applications industrielles, les champs électromagnétiques sont susceptibles d’altérer la santé des travailleurs exposés. Afin d’aider les entreprises à évaluer et à prévenir ces risques, l’INRS publie en coopération avec l'INERIS une nouvelle brochure à visée opérationnelle (de référence ED 6136).

Global warming will increase heat stress at home and at work. Few studies have addressed the health consequences in tropical low and middle income settings such as Thailand. We report on the association between heat stress and workplace injury among workers enrolled in the large national Thai Cohort Study in 2005 (N=58,495). We used logistic regression to relate heat stress and occupational injury separately for males and females, adjusting for covariate effects of age, income, education, alcohol, smoking, Body Mass Index, job location, job type, sleeping hours, existing illness, and having to...
The potential impacts of climate change (CC) on Occupational Health and Safety (OHS) have been studied a little in tropical countries, while they received no attention in northern industrialized countries with a temperate climate. This work aimed to establish an overview of the potential links between CC and OHS in those countries and to determine research priorities for Quebec, Canada. A narrative review of the scientific literature (2005–2010) was presented to a working group of international and national experts and stakeholders during a workshop held in 2010. The working group was invited...
The current system of International Standards (ISO) is assessed to consider whether standards are fit for purpose for the future in the context of climate change. ISO 7243, ISO 7933 and ISO 9886 provide the current ISO system for the assessment of heat stress. These involve a simple monitoring index, an analytical approach and physiological monitoring, respectively. The system relies on accurate measurement of the thermal conditions experienced by the worker (ISO 7726); and estimations of metabolic heat production due to work (ISO 8996) and the thermal properties of clothing (ISO 9920). As well...
The growing need for valid assessment procedures of the outdoor thermal environment in the fields of public weather services, public health systems, urban planning, tourism & recreation and climate impact research raised the idea to develop the Universal Thermal Climate Index UTCI based on the most recent scientific progress both in thermo-physiology and in heat exchange theory. Following extensive validation of accessible models of human thermoregulation, the advanced multi-node 'Fiala' model was selected to form the basis of UTCI. This model was coupled with an adaptive clothing model...
Un dossier sur les expositions multiples est paru dans le dernier numéro de la revue Travail et sécurité. Les salariés sont quotidiennement confrontés à des expositions multiples dont les effets combinés potentiels sont peu connus. Les préventeurs doivent néenmoins s'emparer de la question afin d'adopter des stratégies adaptées à la réalité du terrain. Un travail pour lequel il est nécessaire de référer les expertises dans des domaines divers : chimie, physique, toxicologie...
The aim of this study was to investigate interaction of noise and mixed organic solvents on blood pressure. Biological interaction of two variables on hypertension was calculated using the synergistic index. The results indicate that exposure to noise or a mixture of organic solvents may be associated with the prevalence of hypertension in car manufacturing company workers and co-exposure to noise and a mixture of solvents has an additive effect in this regard. Therefore appropriate preventive programs in these workers recommended. Source : Mirsaeed Attarchi et al. Combined effects of exposure...
Objectives : To determine the cardiovascular and hemostatic effects of fire suppression and postexposure active cooling. Methods : Forty-four firefighters were evaluated before and after a 12-minute live-fire drill. Next, 50 firefighters performing the same drill were randomized to undergo postfire forearm immersion in 10[degrees]C water or standard rehabilitation. Results: In the first study, heart rate and core body temperature increased and serum C-reactive protein decreased but there were no significant changes in fibrinogen, sE-selectin, or sL-selectin. The second study demonstrated an increase...
More attention and monitoring of occupational radiation exposure in the natural gas industry are warranted . The boom in the natural gas industry across the nation, made possible by recent advances in hydraulic fracturing ("fracking") methodology, has resulted in increased concern for public and environmental safety. This, in turn, has resulted in a series of recommendations for minimizing the risk to the public and the environment (Secretary of Energy, 2011). The natural gas industry has responded to environmental concerns by cleaning and recycling frack water, which can take the form...
Cette fiche : - présente et décrit les principales technologies utilisées dans les réseaux sans fil de proximité ; - donne les valeurs de niveaux de champs électriques mesurés à proximité de matériels typiques et les valeurs de références définies par la recommandation du Conseil 1999/519/CE du 12 juillet 1999 (relative à la limitation de l'exposition du public aux champs électromagnétiques) et 2004/40/CE du 29 avril 2004 (relatives à l'exposition des travailleurs) sur...
The aim of this study was to verify that in a hot environment, the subjective state could affect cognitive performance before any increase in core temperature. Eighteen volunteers performed a planning (OTS) and a reaction time task in hot and control environments. Before starting the cognitive assessment, subjects completed the Positive and Negative Affect Schedule (PANAS) and provided subjective measures of thermal comfort and thermal sensation. Our results showed that while simple tasks were not affected, complex cognitive task performance was significantly reduced in the HOT. Furthermore, although...
The health, safety and environmental risks associated with hydraulic fracturing (often termed 'fracking') as a means to extract shale gas can be managed effectively in the UK as long as operational best practices are implemented and enforced through regulation.
