Notes on Other Potential Health Effects and Hazards

  1. Impairment of cognitive function, motor dysfunction, and peripheral neuropathy have been reported in limited studies of workers exposed to aluminum fumes (NLM 2012).
  2. Chronic occupational exposure to aluminum dust and fumes can cause signs of cholestasis (Bogdanovic and Bulat 2008).

Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):

Federal OSHA and OSHA State Plan personnel submitting samples to the OSHA Salt Lake Technical Center 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 ID-121)
    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. current elemental analysis method: Lithium Borate Fusion/AAS or Microwave Digestion/AAS
    method reference: OSHA Analytical Method (OSHA ID-109-SG 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.
