Exposure Limits

OSHA Permissible Exposure Limit (PEL):

General Industry: 0.5 ppm, 2.8 mg/m3 Ceiling
Construction Industry: 0.5 ppm, 2.8 mg/m3 Ceiling

American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV): 0.1 ppm, 0.53 mg/m3 TWA; Appendix A4 (Not Classifiable as a Human Carcinogen)

National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 0.1 ppm TWA, Potential Carcinogen

Health Factors

Potential Symptoms: Eye, respiratory system irritation; skin burns (carcinogenic) In animals: hematopoietic system, lung, liver, kidney damage

Health Effects: Irritation-Eyes, Nose, Throat, Lungs, Skin---Marked (HE14) Cumulative systemic toxicity (HE3); Mutagen (HE2)

Affected Organs: Skin, eyes, respiratory system

Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):

Industrial hygienists have been concerned about the presence of Diglycidyl Ether during the manufacture of the epoxy resin called Diglycidyl Ether of Bisphenol A. Diglycidyl Ether is not present in this process. The starting compounds are Epichlorohydrin and Bisphenol A.
