Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):

Compliance

  • sampling media: tared 37-mm diameter low-ash polyvinyl chloride filter in 3-piece polystyrene cassette preceded by a spark-free vertical elutriator
    recommended volume: 2664 Liters
    flow rate: 7.4 L/min for 6 hours
    current analytical method: Gravimetric
    method reference: OSHA Analytical Method (Appendix A 29 CFR 1910.1043)
    method classification: Validated
    note:
    1. OSHA personnel can obtain tared sampling media from the Salt Lake Technical Center.
    2. OSHA personnel can borrow a vertical elutriator from the Cincinnati Technical Center, a regional office or the Salt Lake Technical Center. Vertical elutriators can also be obtained on a commercial rental basis.
    3. If the filter is not overloaded, samples can be collected up to an 8-hour period.

Screening

  • sampling media: tared 37-mm diameter low-ash polyvinyl chloride filter
    maximum volume: 960 Liters
    maximum flow rate: 2.0 L/min--DO NOT USE A CYCLONE--
    current analytical method: Gravimetric
    method reference: OSHA Analytical Method (OSHA PV2121)
    method classification: Partially Validated
    note: OSHA personnel can obtain tared sampling media from the Salt Lake Technical Center.
