Technical Basis
A review of available sources identified AEGLs and TWA for this chemical. The AEGLs were selected as the TEELs due to their priority among the emergency exposure limits (Section 1). Due to insufficient data, an AEGL-1 does not exist for this chemical; instead, the TLV-TWA was selected as the TEEL-1 basis (Table 3.5, Section 3.4.2).
• TEEL-1 = TLV-TWA (25 ppm) x 3
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL values consistent with Rev. 29A*.
• TEEL-1 = TLV-TWA (25 ppm) x 3
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL values consistent with Rev. 29A*.
