Technical Basis
A review of available sources identified AEGLs for this chemical. The AEGLs were selected as the TEELs due to their usage priority among the emergency exposure limits (Section 1).
• TEEL-1 = AEGL-1
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL values are consistent with previous Rev 29A values.
Note: AEGL-2 and AEGL-3 values exceed the lower explosion limit of this chemical (10-49% LEL for AEGL-2 and ≥100% LEL for AEGL-3) and " extreme safety considerations against the hazard(s) of explosion(s) must be taken into account.”
