level of exposure to the work force include the duration of exposure, the characteristics of the
workroom, the other sources of dust and noise, etc., i.e. the number of machines and other
adjacent processes. Also the permissible exposure levels can vary from country to country. This
information, however, will enable the user of the machine to make a better evaluation of the
hazard and risk.
