Technical Basis
A review of available sources did not identify exposure limits or acute toxicity data for lanthanum phosphate. Reported GHS health hazard ratings (H315 and H319, Category 2; H335 Category 3) and NFPA and HMIS health hazard=2 ratings, indicate a mid-level health hazard, approximately equivalent to an HHR=2. Analysts assumed an HHR=2 as the TEEL-3 basis (Section 3.4.5). TEEL-1 and TEEL-2 values were derived according to Table 3.5.
• PAC-1 = TEEL-1 = TEEL-2/11
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = HHR=2
This review generated PAC values consistent with Rev. 29A*.
