Technical Basis
A review of available sources did not identify exposure limits or acute toxicity data for 1,8-diazabicylo(5.4.0)undec-7-ene. GHS health safety codes indicate Category 1 (H314, H318) health hazards, specifically severe skin and eye damage, associated with this chemical. As such, analysts assumed an HHR=3 as the TEEL-3 basis (Section 3.4.5). TEEL-2 and TEEL-1 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = HHR=3
This review generated TEEL values that are consistent with Rev. 29A*.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = HHR=3
This review generated TEEL values that are consistent with Rev. 29A*.
