Notes
 

If the net weight of the sample yields a concentration below the PEL after considering the associated SAE , the SLTC will perform no further work on the sample and the sample air concentration will be reported as the calculated gravimetric air concentration. If the net weight corresponds to an amount greater than the PEL value after considering the associated SAE, the sample may be analyzed for  the applicable component and appropriate results will be reported.

Special requirements
 

FOR TOTAL DUST SAMPLES, DO NOT USE A CYCLONE!!

Bulk Method
 

Submit a sample of the bulk oil substance in a separate mailing container other than used for air samples. Indicate on the air sample submission sheet that a bulk sample has been submitted. Cutting oils may contain nitrosamines.The bulk sample is determined to fluoresce or not to fluoresce, and then the appropriate analysis method is used to perform the analysis (OSHA ID-128 (partially validated) [fluorescent], OSHA ID-178SG (partially validated) [non-fluorescent]).
