Technical Basis
There was no acute toxicity data or exposure limits for this compound. A review of available sources identified AEGLs for a similar chemical, HFC 134A (CASRN: 811-97-2). The AEGLs were selected as the TEELs due to their priority among the emergency exposure limits (Section 1).
• TEEL-1 = AEGL-1 (HFC 134A, CASRN: 811-97-2)
• TEEL-2 = AEGL-2 (HFC 134A, CASRN: 811-97-2)
• TEEL-3 = AEGL-3 (HFC 134A, CASRN: 811-97-2)
This review generated TEEL values that are consistent with Rev. 29A*.
• TEEL-1 = AEGL-1 (HFC 134A, CASRN: 811-97-2)
• TEEL-2 = AEGL-2 (HFC 134A, CASRN: 811-97-2)
• TEEL-3 = AEGL-3 (HFC 134A, CASRN: 811-97-2)
This review generated TEEL values that are consistent with Rev. 29A*.
