Technical Basis
A review of available sources identified the following: several occupational exposure limits (TLV-TWA, LOC, IDLH) and animal toxicity data. Data sources were selected according to the hierarchy listed in Table 3.1. The IDLH (1990) was selected as the TEEL-3. The LOC was selected as the TEEL-2. The TLV-TWA was selected as the TEEL-1 basis.
• TEEL-1 = TLV-TWA x 3 (0.2 mg/m3)
• TEEL-2 = LOC (0.7 mg/m3)
• TEEL-3 = IDLH (1990) (20 mg/m3)
This review generated TEEL values which are consistent with those in Rev. 29A.
