SYMPTOMS: Symptoms of exposure to this compound may include irritation of the skin, eyes, mucous membranes and upper respiratory tract. ACUTE/CHRONIC HAZARDS: This chemical is harmful by inhalation, ingestion or skin absorption. It is an irritant of the skin, eyes, mucous membranes and upper respiratory tract. When heated to decomposition it emits highly toxic fumes of chlorides, carbon monoxide, carbon dioxide and hydrogen chloride gas. (NTP, 1992)
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 pulmonary edema and treat if necessary . Monitor for shock 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 patient can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal . Aromatic hydrocarbons and related compounds

Environmental considerations: Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash, cement powder, or commercial sorbents. Apply universal gelling agent to immobilize spill. Apply appropriate foam to diminish vapor and fire hazard. Chlorobenzene
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.

Combustible when exposed to heat or flame.1,2,4,5-TETRACHLOROBENZENE is incompatible with strong oxidizing agents. Reacts violently with sodium hydroxide in methanol. Several explosions have occurred during alkaline hydrolysis. (NTP, 1992)

Serious accidents have occurred during the commercial preparation of 2,4,5-trichlorophenol by alkaline partial hydrolysis of 1,2,4,5-tetrachlorobenzene during the period 1949 to 1976 ... The earlier process used methanolic alkali under autogenous pressure to effect the hydrolysis, and on 2 occasions around 1949 the reaction at 125 deg C went out of control, one attaining 400 deg C. ... In a further incidents in 1953, the explosion was associated with the post reaction stage during distillation of methanol from the reaction mixture. The later process used ethylene glycol as solvent to effect hydrolysis with sodium hydroxide and operated essentially at or near atmosphere pressure. ... Violent decomposition could ... occur during the subsequent solvent distillation phase in the absence of effective temp control. A laboratory residue from vacuum stripping using electric heating (without knowledge of the liquid temp) exploded when the vapor temp had reached 160 deg C. In the Coalite plant incident in 1968, where the hydrolysis was run at about 180 deg C in a reaction vessel heated by circulating oil at 300 deg C, failure of the manually regulated oil heating system led to an uncontrollable temp incr during 50 min to above 250 deg C, when a violent explosion occurred.
When heated to decomposition it emits highly toxic fumes of /hydrogen chloride/.

The substance may have effects on the liver. This may result in liver impairment.
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.
Using the Warburg technique, 1,2,4,5-tetrachlorobenzene was not biologically-oxidized by benzene-acclimated activated sludge at a concn of 500 ppm over 192 hr of incubation(1). Microbial decomposition of 1,2,4,5-tetrachlorobenzene by a Pseudomonas sp. or by a mixed culture of soil bacteria yielded 2,3,5,6-tetrachlorophenol(2,3). An analysis of monitoring data from sediment cores indicated insufficient evidence to show occurrence of anaerobic dehalogenation of tetrachlorobenzene in Lake Ontario sediments(4). Anaerobic incubation of 1,2,4,5-tetrachlorobenzene with mixed primary sewage sludge for 32 days reduced its concn by 61%(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.
