Technical Basis
A review of available sources did not identify exposure limits or acute toxicity data for 7-amino-1,3-napthalenedisulfonic acid. Only 1 of 3 SDS report associated GHS health hazards; as such, this chemical was evaluated as a Particle Not Otherwise Specified (PNOS,10 mg/m3, Section 3.5.2). The TEEL-2 and TEEL-3 values were derived according to Table 3.5.
• TEEL-1 = TLV-TWA (10 mg/m3) x 3
• TEEL-2 = TEEL-1 x 11
• TEEL-3 = TEEL-2 x 6
This review generated TEEL values that are consistent with Rev. 29A*.
• TEEL-1 = TLV-TWA (10 mg/m3) x 3
• TEEL-2 = TEEL-1 x 11
• TEEL-3 = TEEL-2 x 6
This review generated TEEL values that are consistent with Rev. 29A*.
