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):

Federal OSHA and OSHA State Plan personnel submitting samples to OSHA SLTC Laboratory for Aluminum (as Al, soluble salts) 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 SLTC.
    note: If the net weight of the sample yields a concentration below the standard for the substance, SLTC 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. 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 extracted with deionized water and then 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 water soluble or partially water soluble aluminum compounds.
