Notes

Samples collected for this compound are first analyzed gravimetrically. If the gravimetric result of a sample yields a concentration below the permissible exposure limit (PEL), the Salt Lake Technical Center will report the calculated air concentration for the requested compound solely from the gravimetric result, qualified as less than or equal to the gravimetric result; no further work on the sample will be performed. If the gravimetric result indicates an air concentration greater than the PEL, the sample will proceed for elemental analysis.

Results will be reported from the elemental analysis for the element only; the stated identity of the actual sample contents is based on the assumption that the material sampled is as identified by the compliance officer using available documentation of materials and processes. An elemental result provided may be converted to the desired compound by multiplying the result by the appropriate stoichiometric factor.

A 91B report specific to the compound (including the stoichiometric conversion) may by be provided upon request by contacting the laboratory. The stoichiometric factor for titanium dioxide from titanium is 1.668. The physical form of a sample (dust, mist, or fume) is identified by the compliance officer using available documentation of materials and processes.

Special requirements

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

* All sampling instructions above are recommended guidelines for OSHA Compliance Safety and Health Officers (CSHOs), please see the corresponding OSHA method reference for complete details.
