ACCIDENTAL RELEASE MEASURES Personal precautions, protective equipment and emergency procedures Use personal protective equipment. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. For personal protection see section Environmental precautions Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided. Methods and materials for containment and cleaning up Keep in suitable, closed containers for disposal.

NO open flames. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage.

CombustibleDIISODECYL PHTHALATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Can generate electrostatic charges. [Handling Chemicals Safely 1980. p. 250].

AEROBIC: In a semi-continuous activated sludge test (Soap and Detergent Association biodegradation test method), the mean degradation for diisodecyl phthalate was 68% in 24 hr(1). In a die-away phase of the testing, it took 9 days to achieve 90% degradation(1). Diisodecyl phthalate is confirmed to be degradable in the screening procedure of the Japanese Ministry of Trade and Industry (MITI) which uses a mixed inoculum derived from soil, fresh water and sewage(2). In an acclimated shake flask CO2 evolution test, loss of parent compound (primary degradation) as well as CO2 evolution (ultimate degradation) was measured using an inoculum prepared from soil and sewage, >99% of diisodecyl phthalate was lost and 56% of theoretical CO2 was evolved after 28 days(3). The biodegradation half-life was 9.6 days with a 4.9 day lag(3). Diisodecyl phthalate, present at 100 mg/L, reached 2% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(4). Diisodecyl phthalate, present at a concentration of 100 ppm, was degraded 14 and 30% after three days cultivation in water from the Mino River and Akashi Beach, Japan, respectively(5). Diisodecyl biodegraded 67% from an initial concentration of 48 ppm and 100 ppm in 28 days in activated sludge at 22 and 25 deg C, respectively(6). Diisodecyl phthalate degraded 42% in 21 days at 25 deg C from a starting concentration of 100 ppm(6). An aerobic aquatic half-life of 23 days was given for diisodecyl phthalate(7).

BCFs of <3.6 and <14.4 were measured for diisodecyl phthalate at chemical concentrations of 1 and 0.1 mg/L, respectively, using carp (Cyprinus carpio) which were exposed over an 8-week period(1). According to a classification scheme(2), these BCFs suggest that bioconcentration in aquatic organisms is low(SRC). The mean log BCF of diisodecyl phthalate in Daphnia magna as determined in a 21 day test using ring-labeled chemical was 2.06(3), corresponding to a BCF of 115(SRC). The mean log BCF in mussels (Mytilus edulis) was 3.54 between 14 and 28 days also using ring-labeled ester(4), corresponding to a BCF of 3467(SRC). However depuration was rapid in mussels, the half-life being 3.5 days(4).

Using a structure estimation method based on molecular connectivity indices(1), the log Koc of diisodecyl phthalate can be estimated to be 6.04(SRC). Other estimated log Koc values reported were 5.46 and 5.78(2). According to a classification scheme(3), these estimated log Koc values suggest that diisodecyl phthalate is expected to be immobile in soil. The average Koc of (14)C-diisodecyl phthalate using three standard USEPA sediments (supplied and characterized by the EPA) was measured at 2.86X10+5(4).
