Technical Basis
A review of available sources did not identify exposure limits or acute toxicity data for dinitroaniline orange. Reported GHS health hazard statements for this chemical (H319, Category 2), indicate serious eye irritation but no acute toxicity. Considering this, 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, 10mg/m3) x 3
• PAC-2 = TEEL-2 = TEEL-1 x 11
• PAC-3 = TEEL-3 = TEEL-2 x 6
This review generated PAC values consistent with Rev. 29A*.

PAC values marked with a subscript "A" correspond to 60-minute AEGL values.
PAC values marked with a subscript "E" correspond to ERPG values.
PAC values marked by * are >= 10% lower explosive limit (LEL) but < 50% LEL.
PAC values marked by ** are > 50% LEL but < 100% LEL.
PAC values marked by *** are >= LEL.
