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). An AEGL-1 was not recommended, due to insufficient data, and it was therefore 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 those found in Rev. 29A.
• TEEL-1 = TEEL-2/11
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL values consistent with those found in Rev. 29A.
