Technical Basis
A review of available sources did not identify exposure limits, acute toxicity data, or health hazard ratings for adipic acid, diethylene glycol, trimethylolpropane, phthalic anhydride, toluenediisocyanate polymer, isocyanate terminated. The PNOS TLV-TWA was selected as the TEEL-1 basis (Section 3.5.2). TEEL-3 and TEEL-2 values were derived according to Table 3.5.
• PAC-1 = TEEL-1 = TLV-TWA (PNOS, 10 mg/m3) x 3
• PAC-2 = TEEL-2 = TEEL-1 x 11
• PAC-3 = TEEL-3 = TEEL-2 x 6
This review generated PAC values that are consistent with Rev. 29A*.
• PAC-1 = TEEL-1 = TLV-TWA (PNOS, 10 mg/m3) x 3
• PAC-2 = TEEL-2 = TEEL-1 x 11
• PAC-3 = TEEL-3 = TEEL-2 x 6
This review generated PAC values that are consistent with Rev. 29A*.
