Technical Basis
A review of available sources identified several acute toxicity data (LD50, LC50, LDLo, LCLo, TCLo) for various routes and species, and exposure limits (IDLH, TWAs, STELs, ERPGs). The ERPG values were selected due to their priority among Protective Action Criteria (Section 1).
• PAC-1 = ERPG-1
• PAC-2 = ERPG-2
• PAC-3 = ERPG-3
This review generated PAC-1 and PAC-2 values consistent with Rev. 29A, and an inconsistent PAC-3 value. The Rev. 29A and current TEEL-3 are ERPG-3; however, the current ERPG-3 is the updated (2016), lower limit of 50 ppm. The Rev. 29A and current PAC-2 and PAC-1 sources and values are consistent.
