Technical Basis
A review of available sources identified ERPGs and an AEGL-2 and AEGL-3 for this chemical. The ERPG-1, AEGL-2, and AEGL-3 were selected as the TEELs due to their priority among the emergency exposure limits (Section 1).
• TEEL-1 = ERPG-1
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL values consistent with Rev. 29A*.
• TEEL-1 = ERPG-1
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL values consistent with Rev. 29A*.
