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 values consistent with Rev. 29A*.
