Technical Basis
A review of available sources identified AEGLs for a similar chemical, sarin (CASRN: 107-44-8). The AEGLs were selected as the TEELs due to their priority among the emergency exposure limits (Section 1).
• TEEL-1 = AEGL-1 (sarin, CASRN: 107-44-8)
• TEEL-2 = AEGL-2 (sarin, CASRN: 107-44-8)
• TEEL-3 = AEGL-3 (sarin, CASRN: 107-44-8)
This review generated TEEL values that are consistent with Rev. 29A*.

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.
