Parental occupational chemical exposures and childhood cancer
The risk of childhood cancer has been inconsistently linked with parental exposure to occupational agents, partly because of poor assessment of past exposure.
This project investigated data from the UK Childhood Cancer Study (UKCCS), a nationwide population based case control study, extending previous analyses of parental occupational exposures assessed via a job exposure matrix of job and industry titles. Eight specific work related exposures have been examined as possible risk factors for childhood leukaemia and lymphoma for three exposure time windows (preconception, pregnancy, postnatal).
Indoor Air Quality (IAQ) Tools for Schools (TfS)
EPA developed the Indoor Air Quality (IAQ) Tools for Schools (TfS) Program to reduce exposures to indoor environmental contaminants in schools through the voluntary adoption of sound indoor air quality management practices.
The IAQ Tools for Schools Program is a comprehensive resource to help schools maintain a healthy environment in school buildings by identifying, correcting, and preventing IAQ problems.
Asbestosis-Related Years of Potential Life Lost Before Age 65 Years
Exposure to asbestos fibers can cause asbestosis and other diseases after a latency of 10--40 years from initial exposure to onset of illness. Asbestos still is used in the United States (approximately 2,200 metric tons in 2006) in certain products manufactured domestically. In addition, an undocumented amount of asbestos continues to be imported in products manufactured elsewhere, and a substantial amount of asbestos remains in existing buildings and manufactured products. An estimated 1.3 million construction and general industry workers in the United States potentially are exposed to asbestos each year, mainly from manipulation of asbestos during renovation or demolition activities. Also, although asbestos ore is no longer mined in the United States (4), some U.S. mine workers might remain at risk for exposure to asbestos contained in other ores.
1-BP: A Potential Occupational Hazard
In recent years we have seen an increase in the use of the solvent 1-bromopropane (1-BP) as a substitute for ozone-depleting chlorofluorocarbons and other regulated compounds. 1-BP is used in multiple manufacturing processes, including vapor and immersion degreasing operations to clean electronics and metal and as a solvent vehicle in industries using aerosol applied adhesives such as foam cushion manufacturing. In some states, 1-BP is now being used as an alternative solvent within the dry cleaning industry in response to the restricted use of perchloroethylene, which is considered "probably carcinogenic to humans" by the International Agency for Research on Cancer (IARC).
La nanotechnologie et la sécurité et la santé au travail
Le 27 novembre 2008, le Programme international sur la sécurité et la santé au travail et sur l’environnement (SafeWork) au Bureau international du Travail (BIT) a accueilli une conférence exceptionnelle sur la nanotechnologie. Le Dr John Howard, Directeur sortant de l’Institut national pour la sécurité et la santé au travail (NIOSH) aux Etats-Unis et Président du Comité de rédaction de la la 5e édition anglaise de l’Encyclopédie de sécurité et de santé au travail du BIT, a présenté une vue d’ensemble très complète sur cette nouvelle technologie ainsi que sur ses risques potentiels.
Plus de lymphomes chez les femmes exposées aux solvants organiques
Une étude américaine publiée en décembre dans l’American Journal of Epidemiology suggère l’existence d’un risque accru de lymphome non hodgkinien (LNH), un cancer du système lymphatique, chez les femmes exposées à des solvants organiques sur leur lieu de travail.
New WHSC Resource Helps Inform Those Working To Address Poor Indoor Air
A new hazard bulletin published by the Workers Health & Safety Centre discusses why indoor air can damage the health of workers and what can be done to improve indoor air quality (IAQ).
Panel Blasts Federal Nanotech Risk Research Strategy
A National Research Council (NRC) committee today issued a highly critical report describing serious shortfalls in the Bush administration’s strategy to better understand the environment, health and safety (EHS) risks of nanotechnology and to effectively manage those potential risks.
The report, Review of the Federal Strategy for Nanotechnology-Related Environmental, Health and Safety Research, calls for a significantly revamped national strategic plan that will minimize potential risks so that innovation will flourish and society will reap nanotechnology’s benefits.
La traçabilité des expositions professionnelles
Un rapport établi par l'Inspection générale des affaires sociales (IGAS) présente un dispositif de traçabilité des expositions professionnelles. Il détaille une série de propositions pour assurer au mieux le suivi, dans la durée, des expositions des salariés.

Dans un contexte marqué par un usage croissant des substances chimiques dangereuses notamment CMR (cancérogènes, mutagènes et reprotoxiques) et par une plus grande mobilité géographique des salariés susceptibles d'y être exposés, la traçabilité des expositions professionnelles s'avère aujourd'hui une nécessité. C'est ce que démontre le récent rapport remis par Daniel Lejeune, inspecteur général des affaires sociales au président de la Commission des accidents du travail et des maladies professionnelles (CATMP). 
Reach : plus de 100.000 substances pré-enregistrées

Neurologic Illness Associated with Occupational Exposure to the Solvent 1-Bromopropane
1-Bromopropane (1-BP) (n-propyl bromide) is a solvent increasingly used as a substitute for ozone-depleting chloro-fluorocarbons and similar regulated compounds. 1-BP is used in vapor and immersion degreasing operations and other manufacturing processes, and as a solvent in industries using aerosol-applied adhesives.
Key Design Factors of Enclosed Cab Dust Filtration Systems
Enclosed cabs are a primary means of reducing the silica dust exposure of equipment operators at surface mines. The National Institute for Occupational Safety and Health experimentally investigated various factor effects on cab air filtration system performance. The factors investigated were intake filter efficiency, intake air leakage, intake filter loading (filter flow resistance), recirculation filter use, and wind effects on cab particulate penetration.
Explosion Effects on Mine Ventilation Stoppings
The National Institute for Occupational Safety and Health (NIOSH) and the Mine Safety and Health Administration (MSHA) conducted joint research to evaluate explosion blast effects on typical U.S. mine ventilation stoppings in the Pittsburgh Research Laboratory (PRL) Lake Lynn Experimental Mine (LLEM). An innovative Australian-designed brattice stopping was also evaluated. After mine explosion accidents, MSHA conducts investigations to determine the cause(s) as a means to prevent future occurrences.
Éléments techniques sur l’exposition professionnelle aux fibres minérales artificielles
Ce guide a pour but de présenter les matrices emplois-expositions spécifiques des fibres minérales artificielles développées par le Département santé travail (DST) de l’Institut de veille sanitaire (InVS) et l’Essat (Équipe associée en santé travail ; InVS-DST/Isped-LSTE ; Bordeaux), et de donner des éléments techniques sur l’exposition professionnelle à ces produits en France de 1945 à 2007. Les matrices emplois-expositions fournissent, pour l’ensemble des emplois considérés comme exposés en France, la probabilité, la fréquence et l’intensité d’exposition pour les laines minérales (laine de verre ; laine de roche ; laine de laitier) et pour les FCR.
