Interpretation of Monitoring Results Air sampling results are compared to exposure limits to determine if the potential for hazardous exposure exists. Represents an 8 hour time weighted average legal exposure limit that must not be exceeded. In some cases, the values of these two limits are different. In accordance with Berkeley Lab's Work Smart Standards the lower of the two limits is used to interpret exposure results. When this occurs, the Laboratory uses the lower of the two for its exposure criterion.
Various criteria exist for evaluating the results from wipe and bulk samples.
Where no criteria exists, monitoring results will be provided within 15 days of receiving analytical results for the laboratory performing the analyses. Health Services shall also be notified of hazard assessments where there is a potential for exposure and all monitoring results. Health Services should also be consulted by women who are either pregnant or intend on becoming pregnant. Berkeley Lab's Health Service Program policies and procedures are described in PUB 3000 Chapter 3, Health Services .
