�- LUPEROX DEL`Tp► 9 Material Safety Data Sheet ATOFINA Chemicals, Inc. 10 STABILITY AND REACTIVITY Stability This material is chemically unstable and should only be handled under specified condition& See HANDLING e1VAD .:)TORAGE section of this MSDS for specifiec conditions. SART -Self Accelerating Decomposition Temperature. Lowest temperature at which the tested package size will undergo a self-accelerating decomposition reaction. This reaction will generate flammable vapors which may autoignite. The length of time tc generated a decomposition reaction, after the SADT has been reached or exceeded, is dependent upon how much the SADT has been exceeded and the length of time needed for the reaction exotherm (heat spike from increasing decomposition rate) to initiate a rapid decomposition reaction. Typically, SADT is inversely proportional to package size. Larger packages will have a lower SADT due to smaller ratio to heat transfer area to volume of product. Hazardous Polymerization Does not occur. Incompatibility Contact with strong acids, alkalis, oxidizers, transition metal salts, promoters/accelerators, & reducing agents may result in a violent decomp reaction or in product degradation. (see SECTION 16) Hazardous Decomposition Products Temperatures at or above the SADT can result in the release of hazardous decomposition products which are flammable and may autoignite. 11 TOXICOLOGICAL INFORMATION Toxicological Information Data on this material and/or its components are summarized below. Methyl ethyl ketone peroxide(s) Single exposure (acute)studies indicate that this material (40-60% in dimethyl phthalate) is moderately toxic to rats if swallowed (LD50 484 mg/kg), slightly toxic to rabbits if absorbed through skin (LD50 4,000 mg/kg), practically non-toxic to rats if inhaled (4-hr LC50 17-50 mg/1), corrosive to rabbit eyes, and moderately irritating to rabbit skin (4-hr exposure, 4.5/8.0). Following an allergic skin reaction in a paint sprayer, patch testing produced an allergic skin reaction with this material as well as other components of the paint. However, subsequent patch testing did not produce allergic skin reactions in 34 healthy subjects. Swallowing of this material was reported to cause liver injury in one case report. Repeated oral administration of this material was reported to result in decreased body weight, mild liver and kidney injury and death in rats. Following repeated application of this material in dimethyl phthalate to the skin of rats and mice, severe skin damage and animal deaths (only at the highest dose levels)were the primary effects. Spleen and bone marrow changes considered secondary to the severe skin damage were noted in animals at the high doses. Higher doses applied to rat and mouse skin for a shorter time produced similar effects. Long-term repeated skin application of this material in dimethyl phthalate was reported to enhance skin tumor production in mice irradiated with UVB. This material has produced genetic changes in standard tests using bacterial or animal cells. However, no genetic changes occurred in a standard test using animals. —Product Code: 114000 y�ffi:Y- Revision: 3 issued:16 FEB 2001 Page 5 of 10
