Technical Basis
A review of available sources identified exposure limits (TLV-TWA, LOC, and IDLH,) and animal toxicity data. The IDLH was selected as the TEEL-3; the reported 1990 and 1994 values and bases are the same. The LOC was selected as the TEEL-2. The TLV-TWA was selected as the TEEL-1 basis.
• TEEL-1 = 1 ppm TLV-TWA x 3 (1 ppm)
• TEEL-2 = LOC (0.1 g/m3)
• TEEL-3 = IDLH (1990/1994, 200 ppm)
This review generated TEEL values which are consistent with Rev. 29A.
