The statement was "unless they (employer) can demonstrate there is no silica released above the action level of 25 micrograms per cubic meter of air.
Is anyone willing to put this in layman terms for me? Something people can relate to i.e. (a teaspoon or infintesimal figure)in a cubic meter of air.
