Chemical Description and Physical Properties:

solid

Exposure Limits

American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV): 0.1 mg/m3 TWA (Skin)

National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 0.1 mg/m3 TWA; Skin

Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):

  • sampling media: Mixed Cellulose Ester Filter (MCEF) in series with Midget Fritted Glass Bubbler containing 15 mL Isopropanol
    maximum volume: 48 Liters
    maximum flow rate: 1.0 L/min
    minimum volume: 24 Liters
    current analytical method: Atomic Absorption Spectroscopy; AAS
    method reference: 2 (OSHA In-House file)
    method classification: Not Validated
    note: Sampling times are dependent on the evaporation rate of isopropanol in the bubbler. When an analysis of a compound is requested, an elemental analysis is performed and reported as Manganese.
