Technical Basis
A review of available sources did not identify exposure limits or acute toxicity for bromoethylmagnesium. Instead, analysts evaluated the GHS health hazard codes (H314), a category 1 classification that is approximately equivalent to an HHR=3. Analysts assumed an HHR=3 for 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=3
This review generated TEEL values consistent with Rev 29A.
