Technical Basis
A review of available sources identified acute toxicity data (LC50) data. In addition, AEGLs for a similar chemical, boron trifluoride (BF3, CASRN: 7637-07-2) were evaluated for TEEL development. The boron trifluoride AEGLs 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 inconsistent with Rev. 29A. The Rev. 29A and current bases are the boron trifluoride AEGLs; however, the current values report the AEGLs without molecular weight adjustment (Section 3.2.2).

PAC values marked with a subscript "A" correspond to 60-minute AEGL values.
PAC values marked with a subscript "E" correspond to ERPG values.
PAC values marked by * are >= 10% lower explosive limit (LEL) but < 50% LEL.
PAC values marked by ** are > 50% LEL but < 100% LEL.
PAC values marked by *** are >= LEL.
