title: [Exposure to ceramic fibers in the work environment. III. occupational exposure to ceramic fibers in plants which produce and apply insulation materials made of ceramic fibers].
abstract: The study was aimed at assessing the exposure to dust in the work environment of plants which produced and apply packing and insulation materials made of ceramic fibres. The study revealed that workers were exposed to dust containing respirable ceramic fibres and in some cases (production of packing cord, insulating tape and paperboard) respirable asbestos fibres. The mean concentration of respirable fibres ranged from 0.05 to 0.62 f/l cm3, and concentrations of total dust fell between 0.6 and 23.2 mg/m3. The mean concentrations of respirable fibres were usually below (0.5 f/l cm3 for respirable ceramic fibres with asbestos mixture; 1 f/cm3 for respirable ceramic fibres), and of total dust much higher (1 mg/m3 and 2 mg/m3, respectively) than MAC values proposed. The initial dermatological examinations (25 workers) allow the conclusion that contact with ceramic fibres induces in some workers acute dermatitis and dermal papilla.
