Technical Basis
A review of the limited sources did not identify exposure or toxicity data. A survey of available safety data sheets cites both skin and severe eye exposure effects, in addition to precautionary statements regarding inhalation, indicating at minimum an HHR=11-3. Assuming this, and considering conservatism due to the lack of data, an HHR=2 was used as the starting point to calculate a TEEL-3 (Section 3.4.5). A TEEL-2 and TEEL-1 were calculated from the TEEL-3 value, according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TEEL-3/6
• TEEL-3 = Estimated from HHR=2 (rat oral LD50 4000 mg/kg)
This review generated TEEL values are consistent with those published in Rev. 29A.
