| Notes |
OSHA personnel can obtain pre-cleaned filters, vials, and Teflon-lined caps from SLTC. After sampling, filter must be transferred to a glass vial with a PTFE-lined cap. Sample must be protected from direct sunlight. |
| Special requirements |
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. |
* 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:
Not established. Pyrene 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 chrysene. Pyrene is characteristic of cold tar pitch volatiles (PEL is 0.2 mg/m³) and/or coke oven emissions (PEL is 0.15 mg/m³). |
