Technical Basis
A review of available sources did not identify exposure limits or acute toxicity data for bromotrimethylsilane. The GHS code (H314, Category 1) for bromotrimethylsilane indicates a high-level health hazard, approximately equivalent to an HHR=3. Analysts assumed an HHR=3 as the TEEL-3 basis (Section 3.4.5). TEEL-2 and TEEL-1 values were derived according to Table 3.5.
• PAC-1 = TEEL-1 = TEEL-2/11
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = HHR=3
This review generated PAC values consistent with Rev. 29A.
