Technical Basis
A review of available sources did not identify exposure limits or acute toxicity data. The chemical is classified as having an NFPA rating of 2 by numerous SDS and GHS classification codes corresponding to irritation to skin, eyes, and inhalation (H315, H319, H335). Considering these classifications, an HHR=2 was assumed 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=2 (LD50 rat oral = 4,000 mg/kg)
This review generated TEEL values consistent with the previous Rev. 29A.
