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.

Primary Laboratory Sampling/Analytical Method (SLC1):

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.

• sampling media: 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.
