OSHA IMIS Code Number: A103
Chemical Abstracts Service (CAS) Registry Number: 7429-90-5
Chemical Description and Physical Properties:
American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV): 2 mg/m3 TWA
National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 2 mg/m3 TWA
Health Effects: Explosive, Flammable, Safety (No adverse effects encountered when Good Housekeeping Practices are followed) (HE18)
Primary Laboratory Sampling/Analytical Method (SLC1):
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.
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.
** All Trademarks are the property of their respective owners.
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.
