Technical Basis
A review of limited sources identified LOC. Data sources were selected according to the hierarchy listed in Table 3.1. The LOC was selected as the TEEL-2. TEEL-3 and TEEL-1 values were derived according to Table 3.5.
• TEEL-1 = TEEL-2/11
• TEEL-2 = LOC (as Zinc, dichloro(4,4-dimethyl-5-((((methylamino)carbonyl)oxy)imino)pentanenitrile)-,(T-4)-; 0.009 g/m3)
• TEEL-3 = TEEL-2 x 6
This review generated TEEL values that are consistent with Rev. 29A*.

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.
