Additional Information:

  • Occupational Health Guidelines for Chemical Hazards. US Department of Health and Human Services (DHHS), National Institute for Occupational Safety and Health (NIOSH) Publication No. 81-123, (1981, January). Provides a table of contents of guidelines for many hazardous chemicals. The files provide technical chemical information, including chemical and physical properties, health effects, exposure limits, and recommendations for medical monitoring, personal protective equipment (PPE), and control procedures.

Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):
  • sampling media: Tared Low Ash Polyvinyl Chloride (LAPVC) filter 5 microns preceded by 10 mm Nylon Cyclone
    maximum volume: 816 Liters
    maximum flow rate: 1.7 L/min
    current analytical method: Gravimetric
    method reference: 11, 12
    sampling analytical error: 0.10
    method classification: Fully Validated
    note: If the gross weight sample yields a concentration below the standard for the air contaminant, do not submit the sample to the Salt Lake Technical Center for analysis. If a gravimetric analysis is not sufficient, submit + the filter to the Salt Lake Technical Center for XRD analysis for quartz (OSHA Method ID-142). Submit bulk sample in separate package when quartz analysis is requested.
