Aluminum (as Al), Welding Fumes
OSHA IMIS Code Number: A102
Chemical Abstracts Service (CAS) Registry Number: 7429-90-5
Chemical Description and Physical Properties:
solid
American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV): 5 mg/m3 TWA
National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 5 mg/m3 TWA
Health Effects: Explosive, Flammable, Safety (No adverse effects encountered when Good Housekeeping Practices
are followed) (HE18)
NIOSH/OSHA/DOE Health Guideline: Aluminum
Laboratory Sampling/Analytical Method:
Federal OSHA and OSHA State Plan personnel submitting samples to OSHA SLTC Laboratory for Aluminum (as Al, welding fumes) 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 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: Lithium Borate Fusion/AAS or Microwave Digestion/AAS
method reference: OSHA Analytical Method (OSHA ID-109SG or OSHA ID-198SG)
method classification: Partially Validated
note: Submit as a separate sample. When analysis of a compound is requested, an elemental analysis is performed and reported as the compound. The analytical method does not distinguish between dust and fume.
