Notes

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.

Special requirements

* All sampling instructions above are recommended guidelines for OSHA Compliance Safety and Health Officers (CSHOs), please see the corresponding OSHA method reference for complete details.
