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