Notes

Submit as a separate sample. If the filter is not overloaded, samples may be collected up to an 8-hour period.

If polycyclic aromatic hydrocarbons (PAHs) are suspected to be present, take and submit separate samples on glass fiber filters per OSHA Method 58.

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.
