Technical Basis
A review of available sources identified exposure limits for this chemical including AEGLs. The AEGLs were selected as the TEELs due to their priority among the emergency exposure limits (Section 1).
• TEEL-1 = AEGL-1
• TEEL-2 = AEGL-2
• TEEL-3 = AEGL-3
This review generated TEEL ppm values that are consistent with Rev. 29A. The minor difference in the Rev. 29A reported TEEL-3 value in units of mg/m3 may be due to conversion and rounding of this value, instead of use of the source value. Values in units of mg/m3 are reported as published in the EPA technical support document Table 1-1, per handbook guidance (Section 3.4.7.2)

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.
