Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for shock and treat if necessary . Anticipate seizures and treat if necessary . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patent can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal . Aniline and related compounds

For rescue purposes wear full protective clothing. fight fire from an explosion-resistant location. In advanced or massive fires, area should be evacuated. If fire occurs in vicinity of this material water should be used to keep containers cool.

Special Hazards of Combustion Products: Emits highly toxic fumes of oxides of nitrogen. May explode. Behavior in Fire: Severe explosion hazard when exposed to heat or flame, or when shocked. (USCG, 1999)

Use water spray, foam, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.

Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

1. Remove all ignition sources. 2. Ventilate area of spill. 3. For small quantities, sweep onto paper or other suitable material and burn in suitable combustion chamber which allows burning in unconfined condition & is equipped with appropriate effluent gas cleaning device. Large quantities may be reclaimed; however, if this is not practical, dissolve in fuel oil and atomize in suitable combustion chamber equipped with an appropriate effluent gas cleaning device.

NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust. 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.

May explode on heating even in the absence of air. On combustion, forms toxic gases and fumes including nitrogen oxides. Reacts violently with strong oxidants, strong bases and reducing metals such as zinc and tin. This generates fire and explosion hazard. Mixtures with nitric acid are highly explosive.

Combustible when exposed to heat or flame; can react vigorously with oxidizing materials.Dust explosion possible if in powder or granular form, mixed with air.All three isomers have similar properties and may react vigorously with oxidizing materials. Their reaction with nitric acid (nitration) will lead to a mixture of trinitrobenzenes possessing high-explosive properties [Urbanski, 1967, vol. 3, p. 290]. If heat and reaction conditions of the nitration are not controlled, detonation comparable to TNT may occur [Anon., J. R. Inst. Chem., 1960, 84, p. 451]. Mixture of 1,3-dinitrobenzene with tetranitromethane was found highly explosive [Urbanski, 1964, vol. 1, 592]. 1,2-dinitrobenzene is a severe explosion hazard when shocked or exposed to heat or flame. When heated to decomposition all dinitrobenzens emit toxic fumes of nitrogen oxides [Sax, 9th ed., 1996, p. 1374].

Contact with strong oxidizers may cause fires & explosions. Contact with caustics & metals such as tin & zinc may cause evolution of heat & incr in pressure.

When heated to decomposition it emits highly toxic fumes of /nitrogen oxides/, & explodes.

The substance is irritating to the eyes and respiratory tract. 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.

The substance may have effects on the liver. This may result in liver impairment. The substance may have effects on the blood. This may result in anaemia.

No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C.

Decomposition by a soil microflora: > 64 days.

A BCF value of 10 was measured for 1,2-dinitrobenzene in fish(1). BCF values of 2-38 were measured in carp exposed to dinitrobenzene (isomer not specified) over a 6 week incubation period(2). According to a classification scheme(3), these BCF values suggest bioconcentration in aquatic organisms is low to moderate(SRC).

The Koc of 1,2-dinitrobenzene is estimated as 200(SRC), using a measured log Kow of 1.69(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1,2-dinitrobenzene is expected to have moderate mobility in soil. It has been shown that nitrophenols and nitrobenzenes adsorb strongly to clay through an interaction between the nitro group and the water molecules or metallic cations in the clay(4). However, it has also been shown that ortho substituents on the benzene ring, as in the case of 1,2-dinitrobenzene, diminish this adsorption due to steric effects(5). The adsorption of 1,4-dinitrobenzene and 1,2-dinitrobenzene was studied in monmorillonite, kaolinite and illite clays(5). Adsorption coefficients (Kd) of 188, 1,460 and 3,100 L/kg were measured in kaolinite, illite and monmorillonite, respectively for 1,4-dinitrobenzene, while the adsorption coefficients were only 0.4, 2.5 and 4.2 L/kg for 1,2-dinitrobenzene(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.
