In industrial situations, concentration values below the TWA value should be maintained. Values may be reduced by
process modification, use of local exhaust ventilation, capturing substances at the source, or other methods. If you
believe air borne concentrations of mists, dusts or vapours are high, you are advised to modify the process or
environment to reduce the problem.
