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).
• TEEL-1 = AEGL-1
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL ppm values that are consistent with Rev. 29A. Minor differences in the reported TEEL-2 and TEEL-3 values in units of mg/m3 may be due to conversion and rounding of these values, instead of use of source values. Values in units mg/m3 are reported as published in the technical support document Table 1, per handbook guidance (Section 3.4.7.2).
