Technical Basis
A review of available sources identified the following exposures: a TLV-TWA, LOC, IDLH exposure limits. 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 (0.5 mg/m3) x 3
• TEEL-2 = LOC (0.05 g/m3)
• TEEL-3 = IDLH 1990 (500 mg/m3)
This review generated TEEL-3 and TEEL-2 values consistent with Rev. 29A. The Rev. 29A TEEL-1 was derived from the TEEL-2, while the current TEEL-1 is derived from a TLV-TWA.

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.
