Personal monitoring is conducted by EH&S if there is reason to believe that exposure levels for a substance exceeds the action level (or in the absence of an action level, the permissible exposure limit). Examples where personal monitoring may be conducted include: (1) volatile chemicals are not used in a fume hood and/or (2) personnel develop signs or symptoms associated with possible hazardous chemical exposure.


The initiation, frequency, and termination of personal monitoring are done in accordance with the relevant regulation.

Communication of Results / Recordkeeping

Monitoring results are provided to laboratory personnel per the time requirements of the relevant regulation or within 15 days of EH&S’s receipt of monitoring results. EH&S maintains copies of exposure monitoring per the regulatory requirement.
