Notes

OSHA 58 is validated in conjunction with Coal Tar Pitch Volatiles and Coke Oven Emissions.

These media are prepared by SLTC as needed and are not available for immediate shipment. Please allow time for SLTC to prepare these media prior to sampling.

Special requirements

After sampling, filter must be transferred to a vial with a Teflon-lined cap. Sample must be protected from direct sunlight.

* 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.

Notes:

Chrysene is a polynuclear aromatic hydrocarbon that OSHA has identified as one of a number of typical components of the benzene-soluble fraction of coal tar pitch volatiles. Other components include anthracene, benzo[a]pyrene, phenanthrene, acridine, and pyrene. Chrysene is characteristic of coal tar pitch volatiles (PEL is 0.2 mg/m³) and/or coke oven emissions (PEL is 0.15 mg/m³). See 29 CFR 1910.1000 Table Z-1, 29 CFR 1910.1029 - Coke oven emissions, and 1910.1002 - Coal tar pitch volatiles; interpretation of term.
