The authors refined the calculation model of dust distribution in the working air flow areas and zones from several sources for the enterprises producing chrysotile asbestos and cement products using a mathematical apparatus. Erasing these patterns, pilot studies of the aspiration volumes values from the enterprise molding workshop technological equipment were carried out. The amount dependences of the dust emission and the dust concentration in the air of the working zone on the aspiration air flow rates for the overflow unit were revealed. The optimal values of the specified parameters necessary to achieve the maximum permissible concentration of chrysotile asbestos dust in the working area air in the building materials’ production are determined.
