[Indoor pollution from airborne glass fibers in biomedical research laboratories]

It is known that the presence of fibers in indoor environment is able to lead to irritative symptoms of skin and mucous membranes. Such troubles have been repeatedly claimed by workers in biomedical research laboratories of our University. For this reason, an investigation for the evaluation of the risk and for propose preventional solutions has been performed (also for absolve fully to D.Lgs. 626/94). On account of the environmental investigations has been revealed the presence of rock wool fibers-included in a water lime matrix-sprayed in big quantity on the ceilings. Therefore, the phases and the methods followed for the analysis of the risks are showed together with evaluations in order to the preventional interventions, also on the basis of what has been established by the lawgiver.
