Technical Basis
A review of available sources identified AEGLs for this chemical. The AEGLs were selected as the TEELs due to their priority among the emergency exposure limits (Section 1). Due to insufficient data, an AEGL-1 does not exist for this chemical; therefore, TEEL-1 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL values consistent with Rev. 29A*. In the supplemental materials, Table D-1 reports a TEEL-2 of 7.5 mg/m3, while Table D-12 reports a TEEL-2 of 7.4 mg/m3. The analyst selected the value consistent with Rev. 29A, given lack of additional information.
