Qualitative Evaluation of Employer Requirements Associated with Occupational Health and Safety as Good Practice in Small-scale Enterprises.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The purpose of this study was to identify what motivates employers to promote good occupational health and safety practices in small-scale enterprises. Previous studies have shown that small-scale enterprises generally pay insufficient attention to issues of occupational health and safety. These findings were mainly derived from questionnaire based surveys. Nevertheless, some small-scale enterprises in which employers exercise good leadership do take a progressive approach to occupational health and safety. Although good practices can be identified in small-scale enterprises, it remains unclear what motivates employers...

[Relationship between occupational health and emergency medicine]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The primary aim for occupational health care is to appropriately control risks related to health problems arising in workplace environments which are caused by work methods. Lowering risks might not always prevent accidents or illnesses; but initial treatment after an accident or of ill workers is crucial work for occupational health care staff. By implementing appropriate initial treatment, it is possible to increase the survival rate of workplace accidents and decrease the rate of illness. Crisis management at the time of an accident is a very important function of occupational health. Thus there is a close relations...

Health Status of Precarious Workers in "Toshikoshi Haken Mura (Dispatch Workers' New Year Village)"Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In Japan, the liquidity of employment is progressing rapidly. Due to the global recession which started in 2008, large-scale unemployment of precarious workers, including dispatch workers, is expected in 2009. In recent studies, it has been suggested that the unstable employment status itself may affect the health conditions of such workers. At the end of 2008, "Toshikoshi Haken Mura" (Dispatch Workers' New Year Village) was established in central Tokyo as a shelter for nearly 500 workers who had lost their jobs and accommodation. We participated in health consultations and medical checkups conducted by the Tokyo Metro...

Effects of nanoparticles on humans.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Methods and end-points used in assessing the hazards of fibrous materials, whose hazards have been assessed, are often employed in studies on the hazards of nanoparticles. Since a possible route of exposure to nanoparticles in work environments is inhalation, data from animal inhalation and intratracheal instillation studies are thought to provide useful insights for assessing the hazards of such particles. Persistent inflammation and fibrosis in the chronic phase and their related factors are particularly important indicators of lung injury. On the other hand, there are some differences in the results of hazard assess...

An action checklist for improving the workplace environment by means of enhancing mental health of workers (Mental Health Action Check List: MHACL) was developed. The use of the checklist for primary prevention was examined. MHACL was developed through three steps: (1) Review of related references and collection of improvement examples for designing a draft MHACL; (2) pilot application of the draft at industrial workplaces and trials at workshops of occupational health staff; and (3) proposing a new MHACL for general use in industry. Workplace improvement actions related to mental health were listed in eight technical ...

[Risk of developing mesothelioma due to neighborhood exposure to asbestos]Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Routes of asbestos exposure consist of occupational and non-occupational exposures, and furthermore the latter is classified as para-occupational, neighborhood or true general environmental exposure. Consequently, in order to evaluate health risk caused by neighborhood exposure to asbestos, it is necessary to exclude risk due to the other exposure routes from overall risk. We reviewed epidemiological studies on the relationship between neighborhood asbestos exposure and risk of mesothelioma. In studies on a crocidolite mine in South Africa and a chrysotile mine in Canada, occupational exposure was not excluded. In stud...

In this study, we calculated total cell concentrations and percentages of cells with esterase activities by the combination of filter sampling and double staining (EtBr and CFDA) from air of a laboratory, a conference room and outdoors. Temperature and humidity in the laboratory were constantly kept by an air conditioner, but in the conference room, an air conditioner was only operated sometimes because of its low frequency of use. There were no significant differences between total cell concentrations and humidity in both rooms, but increase of the percentages of cells with esterase activities depended on rainfall before ...

This study clearly revealed that despite a very low level of OPA in air, symptoms of skin and the respiratory tract can occur. Spreading use of OPA as a substitute for GA may result in serious health risks for HCW. To prevent health hazards from OPA exposure, wearing of a personal protector and use of a fully automated washing machine with a local air exhauster are required.
