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

Federal OSHA and OSHA State Plan personnel submitting samples to the OSHA Salt Lake Technical Center Laboratory for analysis must use the tared gravimetric sampling media described immediately below.
Primary Laboratory Sampling/Analytical Method (SLC1):
  • tared 37-mm diameter low-ash polyvinyl chloride filter
  • maximum volume: 960 Liters
  • minimum volume: 480 Liters
  • maximum flow rate: 2.0 L/min
  • 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.
  • note: If the net weight of the sample yields a concentration below the standard for the substance, the Salt Lake Technical Center will perform no further work on that sample. If the net weight corresponds to an amount greater than the standard, the sample may be analyzed for the appropriate element and the result reported as the substance.
  • note: Refer to Chemical Sampling Information for "alpha-Alumina" when sampling workplaces that have aluminum oxide exposures (welding, etc.).
  • current elemental analysis method: Atomic Absorption Spectroscopy; AAS
  • method reference: OSHA Analytical Method (OSHA ID-121)
  • method classification: Fully Validated
  • alternate analytical method: Samples are prepared as described in OSHA ID-121 and are analyzed by Inductively Coupled Argon Plasma; ICP/AES or ICP/MS.
  • note: When analysis of aluminum metal is requested, an elemental analysis is performed and reported as aluminum metal. The analytical method does not distinguish between dust and fume; or between aluminum metal and other acid soluble or partially acid soluble aluminum compounds.
