Excerpt from ERG Guide 152 [Substances - Toxic (Combustible)]: Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. (ERG, 2016)
Ingestion or overexposure to vapors from hot liquid can cause loss of color, nausea, headache, dizziness, drowsiness, collapse. Hot liquid can burn eyes and skin. Prolonged skin contact with solid can give same symptoms as after inhalation or ingestion. (USCG, 1999)
In case of ingestion, induction of emesis is not recommended because of the potential for central nervous system depression. Gastric lavage and administration of activated charcoal may be considered soon after ingestion, provided airways are protected. Dinitrotoluene

Heating may cause violent combustion or explosion. Decomposes on heating. This produces toxic and corrosive fumes including nitrogen oxides even in the absence of air. Reacts with reducing agents, strong bases and oxidants. This generates fire and explosion hazard.

Dust explosion possible if in powder or granular form, mixed with air.,Dust explosion possible if in powder or granular form, mixed with air.DINITROTOLUENE is incompatible with strong oxidizing agents, caustics, active metals, tin and zinc (NTP, 1992). Decomposes at 250°C. Prolonged heating below this temperature causes some decomposition, and the presence of impurities may decrease the decomposition temperatures. Decomposition is self-sustaining at 280°C. Containers may explode in a fire (USCG, 1999). Reacts with oxidizing agents, caustics, nitric acid, reducing materials and metals such as zinc or tin. May react violently in the presence of a base or when heated to the boiling point. Attacks some forms of plastics, rubbers and coatings. (NTP, 1992).

Dinitrotoluene held at 210 deg C (rather than 125 deg C as intended) for 10 days in a 50 mm steam heated transfer pipeline exploded. Subsequent tests showed decomposition at 210 deg C (producing a significant pressure rise) in 1 day, and presence of sodium carbonate (but not rust) reduced the induction period. A maximum handling temperature of 150 deg C was recommended, (when the induction period was 32 days, or 14 days for alkali contaminated material).
Spontaneously decomposes above 536 deg F (280 deg C) and will cause an explosive if confined. ... Air or oxygen is not required for decomposition or oxidation.

Evaluation: There is inadequate evidence in humans for the carcinogenicity of 2,4-dinitrotoluene. ... There is sufficient evidence in experimental animals for the carcinogenicity of 2,4-dinitrotoluene. ... Overall evaluation: 2,4-Dinitrotoluene ... /is/ possibly carcinogenic to humans (Group 2B).
A significant reduction in sperm counts and normal sperm morphology was observed in one study of chronically exposed workers while several other studies did not report these effects. A small, but statistically significant, increase in spontaneous abortions was reported in one study of chronically exposed workers; several methodological problems with the study were noted. In animals orally exposed to 2,4-dinitrotoluene, decreased fertility was reported. Decreased sperm production, testicular atrophy, and degenerated seminiferous tubules were observed in males, and ovarian atrophy and dysfunction were observed in female rats. No birth defects were observed in the offspring of animals fed 2,4-dinitrotoluene in the diet.
The substance may cause effects on the blood. This may result in the formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.

A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
AEROBIC: 2,4-Dinitrotoluene was reduced by 80%, of which 22% was transformed to 4-amino-2-nitrotoluene and 6% to 2-amino-4-nitrotoluene, by a mixture of microorganisms indigenous to an aquifer which underlies an explosives contaminated site(1); in the same study, approximately 28% of the 2,4-dinitrotoluene was mineralized to carbon dioxide within 28 days, while approximately 20% was not degraded within 28 days(1). In a wastewater treatment plant handling munitions wastewater, aerobic biodegradation of 2,4-dinitrotoluene was accelerated by addition of ethanol and phosphate(2); 4-amino-2-nitrotoluene and 2-amino-4-nitrotoluene were consistently observed as the main biodegradation reduction products(2). 2,4-Dinitrotoluene, present at 100 mg/L, reached 0% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test that suggests the compound is not readily biodegradable(3). In soil column studies using a munitions plant soil previously exposed to 2,4-nitrotoluene, 2,4-nitrotoluene biodegradation of 2,4-dinitrotoluene was rapid in the presence of natural mineral water, but slower in the presence of deionized water(4).
Bioconcentration factor (weighted average) = 3.8 (calculated) for aquatic organisms that contain about 7.6% lipids.
In a loamy sand soil containing an organic matter content of 8.5 g/kg, 2,4-dinitrotoluene had measured Kd adsorption coefficients ranging from 0.28 to 1.11 cu cm/g(1) that correspond to a Koc range of 57 to 225(SRC). In three Chinese soils (organic carbon content of 0.47, 1.0 and 2.2%), measured Freundlich coefficients (Kf) for 2,4-dinitrotoluene ranged from 0.66 to 5.1 mmol-L/kg(2) that correspond to a Koc range of approximately 200 to 1000(SRC). Using a structure estimation method based on molecular connectivity indices(3), the Koc for 2,4-dinitrotoluene can be estimated to be 575(SRC). According to a classification scheme(4), a Koc range of 57-1000 suggests that 2,4-dinitrotoluene can have a high to low mobility range in soil. Leaching of 2,4-dinitrotoluene has been observed in soil column transport studies(5).

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.
