Investigation of chrysotile asbestos dust in air of working zones and environment
IOP Conference Series: Materials Science and Engineering
The article presents an analysis of the chemical composition of chrysotile asbestos and studies the difference between asbestoses of chrysotile and amphibole groups along with their influence on the health of industrial workers. The dispersion analysis of the dust from aspiration systems serving the technological equipment and processes as well as of the dust from the air at the boarder of the sanitary protection zone of enterprise was carried out. In addition, the article describes a method
... scribes a method for the evaluation of technological equipment as a source of dust emissions, that is adapted to the sphere of asbestos cement manufacturing. It also gives an example of determining the air tightness of technological equipment and of calculating the volume of dust emissions in the blank preparation shop of an integrated plant. Furthermore, an investigation of the aerodynamic characteristics of dust of chrysotile asbestos and cement was carried out. The average velocity of dust deposition was determined and the recommendations aimed at reducing the negative influence of dust factor in the air of working zones of enterprises were given.
