Technical Basis
A review of available sources identified a TLV-TWA, AEGL-2, and AEGL-3 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-TWA was considered for the TEEL-1 but resulted in a TEEL-1 > TEEL-2, therefore it was not selected. 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*.
