If there is reason to believe that chemical exposure levels in the workplace exceed the TLV, STEL, or action level for any of the present chemicals EHS or the Department Head will initiate exposure monitoring. If this monitoring discloses employee exposure above the TLV, STEL or action level EHS and the Department Head will determine appropriate steps to mitigate this exposure, including initiating periodic monitoring.
Exposure monitoring serves as a reference when implementing exposure controls and helps to determine the effectiveness of the measures taken. Periodic monitoring may cease once exposure concentrations are shown to be below the TLV, STEL, and action level for the chemical hazards present over the course of two consecutive monitoring events that take place at least seven days apart.
Affected employees will be notified of the monitoring results. Contact EHS for monitoring. Cost for such monitoring is the responsibility of the requesting department.
