Technical Basis
A review of available sources identified the following: a TLV-TWA and IDLH. Data sources were selected according to the hierarchy listed in Table 3.1. The TEEL-2 was calculated according to Table 3.5. The TLV-TWA was selected as the TEEL-1 basis and calculated according to Table 3.5.
• TEEL-1 = TLV-TWA (10 ppm) x 3
• TEEL-2 = TEEL-3/6
• TEEL-3 = IDLH (1990, 400 ppm)
This review generated TEEL values that are consistent with those in Rev. 29A.
