Technical Basis
Boron trifluoride etherate is a complex of boron trifluoride and ethyl ether (1:1) that is used as a source of boron trifluoride in manufacturing. A review of available sources did not identify acute toxicity data or exposure limits for boron trifluoride etherate. There are exposure limits for boron trifluoride (AEGLs, ERPGs; CASRN: 7637-07-2) and ethyl ether (CASRN: 60-29-7). Of these, boron trifluoride is significantly more toxic than ethyl ether; as such, the AEGLs for boron trifluoride were selected as the TEELs due to their priority among the emergency exposure limits (Section 1).
• TEEL-1 = AEGL-1 (boron trifluoride, CASRN: 7637-07-2)
• TEEL-2 = AEGL-2 (boron trifluoride, CASRN: 7637-07-2)
• TEEL-3 = AEGL-3 (boron trifluoride, CASRN: 7637-07-2)
This review generated TEEL values consistent with Rev. 29A*.
• TEEL-1 = AEGL-1 (boron trifluoride, CASRN: 7637-07-2)
• TEEL-2 = AEGL-2 (boron trifluoride, CASRN: 7637-07-2)
• TEEL-3 = AEGL-3 (boron trifluoride, CASRN: 7637-07-2)
This review generated TEEL values consistent with Rev. 29A*.
