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). An AEGL-1 was not recommended for this chemical; therefore, the TEEL-1 was derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL ppm values that are consistent with Rev. 29A; minor differences in TEEL-2 values in units mg/m3 may be due to conversion and rounding, instead of use of the reported source value.
