Technical Basis
A review of available sources identified AEGLs (AEGL-3 and AEGL-2) for this chemical. The AEGLs were selected as the TEELs due to their priority among the emergency exposure limits (Section 1). The TEEL-1 value was 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*.
• TEEL-1 = TEEL-2/11
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL values consistent with Rev. 29A*.
