Asbestos Monitoring
Enclosed are sample results for potential exposure to asbestos.
The OSHA 8-hour permissible exposure limit for asbestos is 0.2 f/cc >5 microns and the 30-minute short term exposure limit is 1 f/cc >5 microns.
The results displayed are based on sampling duration.
The data sheet shows the results of exposure using two methods, the Limit of Detection (LOD) and the Limit of Quantitation (LOQ). Included on the data sheet is an explanation of the method Limit of Quantitation.

* The proper protective clothing was worn during the job. North 7700 Respirator with HEPA filters were worn during die job.
Note: The Limit of Quantitation has been defined as 100 Fibers/MM2 using the minimum fiber loading criteria specified. In the NIOSH analytical method 7400, the stated range of the method Is 100 to 1300 Fibers/MM2 filter area. Although samples below this range can be analyzed, the method has not been validated below 100 Flbers/MM2. However, the NIOSH method 7400 also establishes file estimated Limit of Detection as 7 Flbers/MM2 (Reference OSHA Std. 1910.1001, Appendix B). Based on this Information, we wilt establish 100 Fibers/MM2 fitter area as our Limit of Quantitation and 7 Fibers/MM2 filter area as our Limit of Detection (which Is more representative of the actual fibers present) for asbestos monitoring. We will report both Limit of Quantitation and Limit of Detection.
If only Limit of Quantitation were expressed, the minimum reportable result would calculate to be 0.04 Fibers per cc for an 8-hr. Time weighted average sample at a flow rate ol 2 liters per minute and 0.6 libers per cc tor a 30 minute tlm weighted average short term sample at a flow rate of 2 liters per minute.
