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