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). Values in units mg/m3 are reported as published in the technical support Table 6-1, per guidance (Section 3.4.7.2).
• TEEL-1 = AEGL-1
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL ppm values consistent with Rev. 29A. Minor differences in the TEEL-3 and TEEL-1 values in units mg/m3 may be due to conversion and rounding of these values, instead of use of source values.
