Technical Basis

A review of available sources identified exposure limits for this chemical, including an AEGL-2 and AEGL-3. The AEGLs were selected as the TEEL-3 and TEEL-2 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*.

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.
