Technical Basis
A review of available sources did not identify exposure limits or acute toxicity data for tert-butyl methyl-d3 ether. Instead, AEGLs for a similar chemical, methyl-tertiary-butyl ether (CASRN: 1634-04-4), were evaluated for TEEL development. These AEGLs were selected as the TEELs due to their priority among the emergency exposure limits (Section 1).
• TEEL-1 = AEGL-1 (methyl-tertiary-butyl ether, CASRN: 1634-04-4)
• TEEL-2 = AEGL-2 (methyl-tertiary-butyl ether, CASRN: 1634-04-4)
• TEEL-3 = AEGL-3 (methyl-tertiary-butyl ether, CASRN: 1634-04-4)
This review generated TEEL values consistent with Rev. 29A*.

PAC values marked with a subscript "A" correspond to 60-minute AEGL values.
PAC values marked with a subscript "E" correspond to ERPG values.
PAC values marked by * are >= 10% lower explosive limit (LEL) but < 50% LEL.
PAC values marked by ** are > 50% LEL but < 100% LEL.
PAC values marked by *** are >= LEL.
