Technical Basis
A review of available sources identified the following: ceiling exposure limit values (REL-C, TLV-C, PEL-C) and rat LC50 toxicity data. 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 rat LC50 was selected as the TEEL-3 basis and was scaled to 60-minute equivalent using the ten Berge equation (Section 3.3.4). The most preferred ceiling, the TLV-C, was selected as the TEEL-2 basis. TEEL-1 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = TLV-C
• TEEL-3 = Rat LC50 (38 ppm/4H)
This review generated TEEL ppm values that are consistent with Rev. 29A*. Minor differences in the TEEL-2 value in units of mg/m3 may be due to rounding.

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.
