INHALATION OR INGESTION: Headache, vertigo, nausea, vomiting, diarrhea, fever, rapid weak pulse, decreased blood pressure, cyanosis, exhaustion, hepatomegaly, jaundice, albuminurea, hematuria, visual scotomata, amblyopia and nystagmus. EYES: Irritation. SKIN: Stains skin yellow; if skin contact is prolonged, can be absorbed into blood causing same symptoms as for inhalation. (USCG, 1999)

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. 1,2-Dinitrobenzene

Special Hazards of Combustion Products: When heated to decomposition toxic fumes of oxides of nitrogen released. Behavior in Fire: Decomposes explosively. Can be detonated by shock or heat under confinement that will permit high pressure buildup (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! 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. Do NOT let this chemical enter the environment. Personal protection: complete protective clothing including self-contained breathing apparatus.

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 and 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 cleaning 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.

Separated from strong oxidants, strong bases, strong acids and food and feedstuffs. See Chemical Dangers.

Protective gloves. Protective clothing.

Use local exhaust or breathing protection.

On combustion, forms toxic gases and fumes including nitrogen oxides. Reacts violently with strong oxidants, strong bases and metals (tin and zinc). This generates fire and explosion hazard. Mixtures with nitric acid are highly explosive.

no data available

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].

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

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.

More than 64 days were required to achieve a total loss of 1,4-dinitrobenzene when incubated with Niagara silt loam inoculum at 25 deg C(1). No additional data were available concerning 1,4-dinitrobenzene, but 1,2-dinitrobenzene and 1,3-dinitrobenzene are degraded to aromatic amines and ring opened species upon anaerobic and aerobic incubation, respectively, with sewage effluent(2). Dinitrobenzene (isomer not specified), present at 100 mg/l, reached 0 percent of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/l and the Japanese MITI test(3), suggesting biodegradation occurs slowly(SRC).

A BCF value of 5 was measured for 1,4-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), this BCF value suggest bioconcentration in aquatic organisms is low to moderate(SRC).

The Koc of 1,4-dinitrobenzene is estimated as 150(SRC), using a measured log Kow of 1.46(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1,4-dinitrobenzene is expected to have high 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), and 1,4-dinitrobenzene is expected to similarly bind to clays(SRC). The adsorption of 1,4-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(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.
