Technical Basis
A review of available sources identified AEGL-3 and AEGL-2 exposure limits for this chemical. These AEGLs were selected as the TEELs due to their priority among the emergency exposure limits (Section 1). AEGLs were reported only in units of mg/m3. An AEGL-1 was not reported; therefore, the TEEL-1 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 consistent with Rev. 29A.
• TEEL-1 = TEEL-2/11
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL values consistent with Rev. 29A.
