Technical Basis
A review of available sources identified an OEL-TWA, OEL-STEL, AEGL-2, and AEGL-3 for this chemical. The AEGLs were selected as the TEEL-2 and TEEL-3 due to their priority among the emergency exposure limits (Section 1). The OEL-TWA and OEL-STEL were evaluated for the TEEL-1 but were not selected because they resulted in TEEL-1 > TEEL-2. Values in units mg/m3 are reported as published in the technical support document Table 2-70, per handbook guidance (Section 3.4.7.2).
• TEEL-1 = TEEL-2/11
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL ppm values consistent with Rev. 29A. Differences in the reported TEEL-1 and TEEL-2 values in units mg/m3 may be due to conversion and rounding of these values, instead of use of source values.

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.
