Technical Basis
A review of available sources did not identify exposure limits or acute toxicity data for benzo-4,7,13,16,21,24-hexaoxa-1,10-diazabicyclo(8.8.8)hexacosane, 5,6. Reported GHS health hazard ratings (H315 and H319, Category 2; H335, Category 3), indicate a mid-level health hazard, approximately equivalent to a HHR=2. Analysts assumed an HHR=2 as the TEEL-3 basis (Section 3.4.5). The TEEL-2 and TEEL-1 were derived according to Table 3.5.
• PAC-1 = TEEL-1 = TEEL-2/11
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = HHR=2
This review generated PAC values consistent with Rev. 29A*.
