Notes

OSHA 58 is fully 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.

OSHA personnel can obtain pre-cleaned filters, vials, and Teflon-lined caps from SLTC.

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:

Anthracene 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 benzo[a]pyrene, phenanthrene, acridine, chrysene, and pyrene.
