L'Allemagne préconise la substitution des substances hautement sensibilisantes dans les résines époxydes

Les résines époxydes, qui s'emploient couramment dans certains secteurs émergents tels que la production d'éoliennes, l'électronique, l'industrie, le bois, la restauration et la construction, peuvent provoquer de graves allergies cutanées. En Allemagne, le coût du traitement des maladies cutanées a été estimé à 4 millions d'euros en 2011, doublé des coûts dus aux absences dans les entreprises. Et pourtant, les données relatives à ces substances font défaut[..].

NIOSH Puts Health Hazards to Bed at Metal Furniture Manufacturer

Researchers and investigators from the National Institute for Occupational Safety and Health offer an insider's glimpse into a health hazard evaluation of a workplace where metal furniture such as beds and cabinets are manufactured. Employees of a metal furniture manufacturer asked the National Institute for Occupational Safety and Health (NIOSH) to evaluate health hazards at their workplace. They were concerned about exposures to welding fumes and dust from powder painting and grinding operations. Some employees reported breathing problems, excessive tiredness and dust in their noses at the end of their work shifts.

Occupation and environmental heat-associated deaths in Maricopa County, Arizona: a case-control study

Background Prior research shows that work in agriculture and construction/extraction occupations increases the risk of environmental heat-associated death. Purpose To assess the risk of environmental heat-associated death by occupation. Methods This was a case-control study. Cases were heat-caused and heat-related deaths occurring from May-October during the period 2002–2009 in Maricopa County, Arizona. Controls were selected at random from non-heat-associated deaths during the same period in Maricopa County. Information on occupation, age, sex, and race-ethnicity was obtained from death certificates. Logistic regression analysis was used to estimate odds ratios for heat-associated death. Results There were 444 cases of heat-associated deaths in adults (18+ years) and 925 adult controls. Of heat-associated deaths, 332 (75%) occurred in men; a construction/extraction or agriculture occupation was described on the death certificate in 115 (35%) of these men. In men, the age-adjusted odds ratios for heat-associated death were 2.32 (95% confidence interval 1.55, 3.48) in association with construction/extraction and 3.50 (95% confidence interval 1.94, 6.32) in association with agriculture occupations. The odds ratio for heat-associated death was 10.17 (95% confidence interval 5.38, 19.23) in men with unknown occupation. In women, the age-adjusted odds ratio for heat-associated death was 6.32 (95% confidence interval 1.48, 27.08) in association with unknown occupation. Men age 65 years and older in agriculture occupations were at especially high risk of heat-associated death. Conclusion The occurrence of environmental heat-associated death in men in agriculture and construction/extraction occupations in a setting with predictable periods of high summer temperatures presents opportunities for prevention.

Guidance document on developing and assessing adverse outcome pathways

The Adverse Outcome Pathway (AOP) methodology is an approach which provides a framework to collect, organise and evaluate relevant information on chemical, biological and toxicological effect of chemicals. This approach supports the use of a mode (and/or mechanism) of action basis for understanding adverse effects of chemicals. This guidance document intends to provide an insight into which pieces of information are necessary to identify and document an AOP and how to present them. It also provides initial assistance on how to undertake the assessment of an AOP in terms of its relevance and adequacy. A template has been included allowing authors to develop thorough AOPs and to improve consistency in AOPs developed by different stakeholders. The document also briefly outlines the potential use for regulatory purposes of AOP. Detailed guidance on how to use AOPs for integrated testing strategies and risk assessment will be developed in the future.

NIEHS Mold Remediation Guidance

Mold is one of the most widespread hazards that hurricane and disaster clean-up workers are likely to encounter. This guidance was developed by the National Institute of Environmental Health Sciences (NIEHS) as a health and safety resource for workers, volunteers, and homeowners who will participate in hurricane and disaster response and clean-up activities to help them understand how to identify and control hazards from mold. Trainers may use this guidance to aid in the development of a mold remediation awareness level course or other awareness level materials such as fact sheets and table-top activities.

Second Report on Human Biomonitoring of Environmental Chemicals in Canada

The Second Report on Human Biomonitoring of Environmental Chemicals in Canada, published by Health Canada, summarizes the results of the Canadian Health Measures Survey (CHMS) Cycle 2 (2009-2011). The CHMS is a joint initiative of Statistics Canada, Health Canada, and the Public Health Agency of Canada to collect information from Canadians about their general health. In addition, the CHMS collects blood and urine samples to test for chronic and infectious diseases, nutrition and environment markers. The report presents data on concentrations of 91 environmental chemicals in Canadians. Many chemicals that Canadians may be exposed to in the environment are also important occupational exposures, including some occupational carcinogens. The Second Report on Human Biomonitoring includes data on a number of workplace exposures. These include metals such as antimony, arsenic, cadmium, cobalt, copper, lead, mercury, nickel, uranium, and vanadium; benzene; chlorophenols; pesticides including atrazine, carbamates, 2,4-D, organophosphates, and pyrethroids; and polycyclic aromatic hydrocarbons.

Les nanomatériaux sur le lieu de travail. Quels enjeux pour la santé des travailleurs ?

"L'ETUI mène depuis plusieurs années un travail d'information sur les nanotechnologies. Une contribution supplémentaire est apportée avec cette brochure qui traite de la production et de l’utilisation de nanomatériaux sur les lieux de travail. La mise sur le marché et la diversification des usages des nanomatériaux se font à un rythme effréné, alors que l’impact sociétal est loin d’avoir été suffisamment débattu et que le cadre réglementaire européen paraît peu adapté à ces matériaux de taille microscopique. Les données actuelles quant aux risques qu'ils impliquent pour ceux qui les fabriquent ou les utilisent sont éparses et peu systématiques. Des études sur l'animal nous envoient des signaux d’alarme quant à la toxicité de certains d'entre eux."

Working in Australia's heat: health promotion concerns for health and productivity

This exploratory study describes the experiences arising from exposure to extreme summer heat, and the related health protection and promotion issues for working people in Australia. Twenty key informants representing different industry types and occupational groups or activities in Australia provided semi-structured interviews concerning: (i) perceptions of workplace heat exposure in the industry they represented, (ii) reported impacts on health and productivity, as well as (iii) actions taken to reduce exposure or effects of environmental heat exposure. All interviewees reported that excessive heat exposure presents a significant challenge for their industry or activity. People working in physically demanding jobs in temperatures>35°C frequently develop symptoms, and working beyond heat tolerance is common. To avoid potentially dangerous health impacts they must either slow down or change their work habits. Such health-preserving actions result in lost work capacity. Approximately one-third of baseline work productivity can be lost in physically demanding jobs when working at 40°C. Employers and workers consider that heat exposure is a ‘natural hazard’ in Australia that cannot easily be avoided and so must be accommodated or managed. Among participants in this study, the locus of responsibility for coping with heat lay with the individual, rather than the employer. Heat exposure during Australian summers commonly results in adverse health effects and productivity losses, although quantification studies are lacking. Lack of understanding of the hazardous nature of heat exposure exacerbates the serious risk of heat stress, as entrenched attitudinal barriers hamper amelioration or effective management of this increasing occupational health threat. Educational programmes and workplace heat guidelines are required. Without intervention, climate change in hot countries, such as Australia, can be expected to further exacerbate heat-related burden of disease and loss of productivity in many jobs. In light of projected continued global warming, and associated increase in heat waves, more attention needs to be given to environmental heat as a human health hazard in the Occupational Health and Safety arena. Without adoption of effective heat protective strategies economic output and fitness levels will diminish. Health protection and promotion activities should include strategies to reduce heat exposure, limit exposure duration, ensure access to hydration, and promote acclimatization and fitness programmes, and reorientate attitudes towards working in the heat.
