Technical Basis
A review of available sources identified AEGLs for this chemical. The AEGLs were selected due to their priority among the Protective Action Criteria (Section 1). Values in units mg/m3 are reported as published in the technical support Table 4-1, per Section 3.4.7.2
• PAC-1 = AEGL-1
• PAC-2 = AEGL-2
• PAC-3 = AEGL-3
This review generated PAC ppm values consistent with Rev. 29A. Differences in the reported PAC-3 value in units mg/m3 may be due to conversion and rounding of this value, instead of use of the source value.

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.
