The Risk of Lung Cancer After Cessation of Asbestos Exposure in Construction Workers Using Pleural Malignant Mesothelioma as a Marker of Exposure
Objective: To study the risk of lung cancer in heavily asbestos-exposed workers after the exposure to asbestos has ended. Methods: Lung cancer was studied in a cohort of 189,896 Swedish construction workers through a linkage with the Swedish Cancer Registry. Asbestos exposure was estimated by the incidence of malignant mesothelioma in the occupational group. Results: There were in total 2835 cases of lung cancer. Workers with heavy exposure to asbestos had an increased risk of lung cancer (relative risks = 1.74; 95% confidence interval, 1.25 to 2.41) before exposure ended and a similar risk to...
Isocyanate exposure control in motor vehicle paint spraying: evidence from biological monitoring
Aims: The purpose of this work was to assess the changes in control of exposure to hexamethylene diisocyanate based paints used in vehicle spraying after a Health & Safety Executive (HSE) national project. Methods : Paint sprayers and managers from motor vehicle repair (MVR) bodyshops across the UK, were invited to one of 32 Safety and Health Awareness Days (SHADs) to increase their understanding of the hazards, and practical ways of controlling of exposure to isocyanate based paints. Exposure measurement based on biological monitoring was offered, free of charge, to each of the roughly 4000...
Investigation of techniques to discriminate between TDI and TDA exposures in biological samples
Isocyanates continue to be one of the leading causes of occupational asthma in the UK and biological monitoring (BM) is a valuable tool in assessing exposure to them. BM for toluene diisocyanate (TDI) is based on the measurement of toluene diamine (TDA) in urine after acid hydrolysis of any conjugates (‘total TDA’). The work described here has shown some progress in being able to differentiate between TDA and TDI exposures through the analysis of urine samples. Although none of the outcomes are conclusive, there are some tests that can be applied to positive ‘total TDA’...
Guide de prévention des risques chimiques et infectieux chez les travailleurs du domaine funéraire
De nombreux questionnements sur les risques infectieux et chimiques en milieu funéraire ont été soulevés au cours des dernières années et sont à l'origine du présent guide. Celui-ci s'adresse aux enseignants et responsables de formation continue en thanatologie, ainsi qu'aux professionnels et médecins en santé publique. S'y retrouvent une analyse des risques, soutenue par une révision des données scientifiques associées à des observations en milieu funéraire et aux conseils d'experts...
Veille bibliographique sur la surveillance biologique de l'exposition aux produits chimiques en milieu de travail : mise en place d'un réseau francophone multidisciplinaire
L'article présente les étapes de la mise en place d'une veille bibliographique (ou veille scientifique) thématique effectuée conjointement depuis 2005 par 4 institutions francophones du domaine de la santé au travail : l'INRS (France), l'IRSST (Québec), l'IST (Suisse) et l'UCL (Belgique). La thématique suivie est celle de la surveillance biologique de l'exposition aux produits chimiques en milieu de travail. Les données recueillies et mises en forme par les documentalistes servent aux chercheurs spécialistes...
LNG source term models for hazard analysis
A review of the state-of-the-art and an approach to model assessment In 2006, the Health and Safety Laboratory (HSL) undertook a research project to develop tools for the National Fire Protection Agency (NFPA) Liquefied Natural Gas Technical Committee to evaluate liquefied natural gas (LNG) dispersion models. The work was commissioned by the Fire Protection Research Foundation (FPRF) and delivered a Model Evaluation Protocol (Ivings et al., 2007) which included a checklist of model evaluation criteria and a structure for complete model evaluation. A partial evaluation of some common current dispersion...
