Technical Basis
A review of available sources identified exposure limits (IDLH, LOC, TWAs, OEL-STEL) and acute toxicity data (TDLo, LD50) for several species and routes. Data sources were selected according to the hierarchy listed in Table 3.1. Toxicity data were selected according to type of exposure, species, and route according to the hierarchies stated in Sections 3.3.1, 3.3.2, and evaluated using factors in Tables 3.2, 3.3, and 3.4. The 1990 and 1994 IDLHs were evaluated. The 1990 IDLH was an approximate value, derived from an exposure limit. The 1994 IDLH was less than the Level of Concern and the same order of magnitude of the TLV-TWA; as such, it was determined overly conservative. Considering the availability of acute toxicity data, neither IDLH was selected. Instead, the most preferred species and route toxicity data, a rat intraperitoneal LD50 was selected as the TEEL-3 basis. The LOC was selected as the TEEL-2. The OEL-STEL (15-minute, Germany AGS) was selected as the TEEL-1.
• PAC-1 = TEEL-1 = OEL-STEL (15-minute, Germany, 0.24 mg/m3)
• PAC-2 = TEEL-2 = LOC (0.05 g/m3)
• PAC-3 = TEEL-3 = Rat intraperitoneal LD50 (250 mg/kg)
This review generated PAC-3 and PAC-2 values consistent with Rev. 29A and a PAC-1 inconsistent with Rev. 29A. The Rev. 29A TEEL-1 basis was a TLV-TWA, while the current TEEL-1 is an OEL-STEL, a more preferred source (see note, Table 3.5).

This review generated PAC-3 and PAC-2 values consistent with Rev. 29A and a PAC-1 inconsistent with Rev. 29A. The Rev. 29A TEEL-1 basis was a TLV-TWA, while the current TEEL-1 is an OEL-STEL, a more preferred source (see note, Table 3.5).
