Technical Basis
A review of available sources identified the following: TLV-TWA, IDLH, and LD50 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 IDLH was selected, as the most preferred TEEL-3 source. The original IDLH (1990) are recommended, due to no difference in the references cited by the CDC in its revision and handbook preference (see Table 3.1). TEEL-2 and values were calculated according to Table 3.5. The TLV-TWA was selected as the TEEL-1 basis.
• TEEL-1 = TLV-TWA (0.1 mg/m3) x 3
• TEEL-2 =TEEL-3/6
• TEEL-3 = IDLH (1990, 100 mg/m3)
This review generated TEEL values consistent with those in Rev. 29A.
