NOTE: The figures are emission levels and are not necessarily safe
working levels. Whilst there is a correlation between the emission and
exposure levels, this cannot be used reliably to determine whether or
not further precautions are required. Factors that influence the actual
level of exposure of the workforce include the characteristics of the
workroom and the other sources of noise, etc. i.e. the number of
machines and other adjacent processes. Also, the permissible exposure
level 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.
