Technical Basis
A review of available sources did not identify exposure limits or acute toxicity data for diacetyl peroxide. Sources report health hazards as either NFPA=1 or NFPA=3; considering this, and the extreme reactivity of peroxides, analysts assumed an HHR=3 (Section 3.4.5). TEEL-2 and TEEL-1 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=3
This review generated PAC values consistent with Rev. 29A.
• PAC-1 = TEEL-1 = TEEL-2/11
• PAC-2 = TEEL-2 = TEEL-3/6
• PAC-3 = TEEL-3 = HHR=3
This review generated PAC values consistent with Rev. 29A.
