Technical Basis
A review of available sources identified ERPG values for a similar chemical, sodium hydroxide (CASRN: 1310-73-2). The ERPGs were selected as the TEELs due to their priority among the emergency exposure limits (Section 1).
• TEEL-1 = ERPG-1 (sodium hydroxide, CASRN: 1310-73-2)
• TEEL-2 = ERPG-2 (sodium hydroxide, CASRN: 1310-73-2)
• TEEL-3 = ERPG-3 (sodium hydroxide, CASRN: 1310-73-2)
This review generated TEEL values consistent with those found in 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.
