Technical Basis
A review of available sources identified exposure limits (STELs, TWAs) and acute toxicity data (LC50, LD50) for numerous 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 most preferred species and route toxicity data, a 4-hour rat LC50, was selected as the TEEL-3 basis and it was scaled to a 60-minute equivalent using the ten Berge equation (Section 3.3.4). The TEEL-2 value was derived according to Table 3.5. The OEL-STEL (Denmark 20 ppm) was evaluated, however this resulted in a TEEL-1 > TEEL-2. Instead, the TLV-TWA was selected as the TEEL-1 basis (Table 3.5).
• PAC-1 = TEEL-1 = TLV-TWA (0.1 ppm) x 3
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = Rat LC50 (800 ppm/4H)
This review generated PAC values consistent with Rev. 29A*.

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.
