Technical Basis
A review of available sources did not identify exposure limits or acute toxicity data for this chemical. Instead, a similar chemical, phosphorous acid (CASRN: 7664-38-2), was evaluated given that barium phosphate is created by combining phosphoric acid and barium salt. ERPG values for phosphoric acid were identified and selected as the TEELs due to their priority among the emergency exposure limits (Section 1).
• TEEL-1 = ERPG-1 (phosphoric acid, CASRN: 7664-38-2)
• TEEL-2 = ERPG-2 (phosphoric acid, CASRN: 7664-38-2)
• TEEL-3 = ERPG-3 (phosphoric acid, CASRN: 7664-38-2)
This review generated TEEL values consistent with Rev. 29A*.
