Fresh air, rest.
Rinse and then wash skin with water and soap.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth.

Dust explosion possible if in powder or granular form, mixed with air.DIMETHYL TEREPHTHALATE 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]. This compound is sensitive to heat. The molten material reacts with water due to the temperature. This compound is incompatible with strong oxidizers, strong acids and strong bases.

The polymer /produced from DMT/ had been produced for 12 yr by transesterification under nitrogen of the dimethyl ester with ethylene glycol at 250 deg C in presence of titanium butoxide catalyst. After incr the heating capacity of the vessel from a half coil to a full coil, 3 incidents of ignition of vapor after opening the vessel were noted. This is attributed to formation and ignition of mixtures of acetaldehyde or dioxane with ingressing air on the hot vessel surfaces.
When heated to decomposition it emits acrid smoke and irritating fumes.

AEROBIC: Dimethyl terephthalate, present at 100 mg/L, reached 84% of its theoretical BOD in two weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1). A 3 day river die-away test using 50, 40, and 5 ppm dimethyl terephthalate resulted in 100% biodegradation in all three tests of river water, and 27, 38, and 49% biodegradation, respectively, in the three tests of sea water(2). Dimethyl terephthalate, at a concentration of 0.5%, degraded completely in 15 days at 30 deg C in soil with a pH of 8.2 and 60% moisture content(3). The microbe Rhodococcus ruber 2B, isolated from sewage treatment facilities, was shown to accelerate the rate of degradation; terephthalate monoesters and terephthalic acid were identified as metabolites(3).
An estimated BCF of 11 was calculated in fish for dimethyl terephthlate(SRC), using a log Kow of 2.25(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
The Koc of dimethyl terephthalate is estimated as 400(SRC), using a log Kow of 2.25(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that dimethyl terephthalate is expected to have moderate mobility in soil.

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
