Technical Basis
A review of available sources did not identify acute toxicity data or exposure limits for vinyl-2-chloroethylsulfide. Instead, allyl 2-chloroethyl sulfide (C5H9ClS, CASRN: 19155-35-2), a similar chemical, had acute toxicity data that was evaluated for TEEL development. The 10-minute mouse LCLo was selected as the TEEL-3 basis and evaluated using factors in Tables 3.2, 3.3, 3.4 and scaled to 60-minute equivalent using the ten Berge equation (Section 3.3.4). 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 = Mouse LCLo (allyl 2-chloroethyl sulfide, CASRN: 19155-35-2, 500 mg/m3/10min)
This review generated TEEL values that are consistent with Rev. 29A.
