Technical Basis
A review of available sources identified AEGL-2 and AEGL-3 exposure limits for Lewisite 1 (CASRN: 541-25-3), including mixtures with Lewisite 2 (CASRN: 40334-69-8) and Lewisite 3 (CASRN: 40334-70-1). The AEGLs were selected as the TEELs due to their priority among the emergency exposure limits (Section 1). Due to insufficient data, an AEGL-1 does not exist for this chemical, therefore the TEEL-1 value was derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL values that are consistent with Rev. 29A*.
• TEEL-1 = TEEL-2/11
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL values that are consistent with Rev. 29A*.
