Technical Basis
A review of available sources identified exposure limits (TWAs, STELs, ceiling limits, IDLH) and acute toxicity data (LD50, LDLo, LCLo) 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 IDLH were evaluated; the 1994 IDLH was selected because it is based on acute inhalation toxicity data in animals. The lower value 1994 IDLH limit is also support by analysis of available inhalation toxicity data. Available ceiling limits were considered for TEEL-2; however, this resulted in a TEEL-2 < TEEL-1. Instead, the TEEL-2 was derived according to Table 3.5. The MAK-TWA was selected as the TEEL-1 basis.
• PAC-1 = TEEL-1 = MAK-TWA (2 ppm, 6.1 mg/m3)
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = IDLH 1994 (300 ppm)
This review generated PAC values that are consistent with Rev. 29A*. The 1994 IDLH was used according to handbook guidelines (Section 4.2-4.3).
