Technical Basis
A review of available sources identified AEGLs for this chemical. The AEGLs were selected as the TEELs due to their usage priority among the emergency exposure limits (Section 1). Values in units mg/m3 are reported as published in the technical support document Table 2-1, per handbook guidance (Section 3.4.7.2).
• TEEL-1 = AEGL-1
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL values that are consistent with Rev. 29A; minor differences in the reported 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.
