Exposure Limits

OSHA Permissible Exposure Limit (PEL):

General Industry: 29 CFR 1910.1000 Z-1 Table -- 25 ppm, 120 mg/m3 TWA; Skin

Construction Industry: 29 CFR 1926.55 Appendix A -- 25 ppm, 120 mg/m3 TWA; Skin

Maritime: 29 CFR 1915.1000 Table Z-Shipyards -- 25 ppm, 120 mg/m3 TWA; Skin

American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV) : 0.1 ppm, 0.5 mg/m3 TWA; Skin

National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 0.1 ppm, 0.5 mg/m3 TWA; Skin

Health Factors

NIOSH Immediately Dangerous To Life or Health Concentration (IDLH): 200 ppm

Potential Symptoms: Eye, nose, and throat irritation; coughing, shortness of breath, pulmonary edema; kidney, brain damage; dizziness, drowsiness, headache; dry skin; in animals: narcosis; reproductive, teratogenic effects; SKIN ABS; INGES ACUTE: Abdominal pain, nausea, vomiting; weakness; unconsciousness.

Health Effects: Irritiation-Eyes, Nose, Throat, Skin---Mild (HE16); Blood disorders (HE12); CNS effects (HE7); Kidney damage (HE3); Suspected reproductive effects (HE5).

Affected Organs: Eyes, respiratory system, kidneys, brain, CNS, PNS, reproductive system, hematopoietic system.

Notes:

  1. The acetate ester is rapidly converted in the body to methyl cellusolve (2-methoxyethanol), which is further metabolized to aldehyde and acid metabolites that are thought to be involved in reproductive and developmental toxicity, including teratogenicity (see file for Methyl Cellosolve).

Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):

  • sampling media: Charcoal Tube (100/50 mg sections, 20/40 mesh)
    analytical solvent: (95:5) Methylene Chloride:Methanol
    maximum volume: 10 Liters
    maximum flow rate: 0.1 L/min
    current analytical method: Gas Chromatography; GC/FID
    method reference: OSHA Analytical Method (OSHA 53)
    method classification: Fully Validated
    note: Samples for 2-methoxyethyl acetate and/or for 2-ethoxyethyl acetate should be refrigerated upon receipt at the analytical laboratory.

  • sampling media: Charcoal Tube (100/50 mg sections, 20/40 mesh)
    analytical solvent: (95:5) Methylene Chloride:Methanol
    maximum volume: 48 Liters
    maximum flow rate: 0.1 L/min (long term)
    maximum volume: 15 Liters
    maximum flow rate: 0.1 L/min (short term)
    current analytical method: Gas Chromatography; GC/FID
    method reference: OSHA Analytical Method (OSHA 79)
    method classification: Fully Validated
    note: Use these larger maximum volumes to monitor sub-ppm levels. Samples for 2-methoxyethyl acetate and/or for 2-ethoxyethyl acetate should be refrigerated upon receipt at the analytical laboratory.

Wipe Sampling Method:

  • sampling media: charcoal pad
    note: Seal in glass vial for shipment.
