SYMPTOMS: Symptoms of exposure to this compound may include allergic skin reaction and severe eye irritation; and methemoglobinemia upon ingestion or skin absorption followed by cyanosis (2-4 hours). ACUTE/CHRONIC HAZARDS: This compound is toxic by ingestion and it is an irritant. It will emit toxic fumes when heated to decomposition. (NTP, 1992)

Basic treatment: Establish 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

If material on fire or involved in fire: Use dry chemical or carbon dioxide. Cool all affected containers with flooding quantities of water. use water in flooding quantities as fog. Dichloroaniline

Flash point data for this compound are not available. It is probably combustible. (NTP, 1992)

Use water spray, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

AEROBIC: Biodegradation of 2,4-dichloroaniline was not observed in freshwater samples if no sunlight was present. Photolysis of 2,4-dichloroaniline increased bacterial numbers presumably due to the utilization of the degradation products formed(1). Incubation of 2,4-dichloroaniline in covered beakers containing a sandy loam soil for 14 days yielded the azo compound 2,2',4,4'-tetrachloroazobenzene(2). No azo compounds were detected in control incubations using sterilized soil. Products other than azo compounds were not isolated or analyzed for(2). In shake-flask screening tests using soil microbes adapted to isopropyl N-phenylcarbamate, ring degradation of 86-100% was observed for 2,4-dichloroaniline over incubation periods of 8-22 days(3). No microbial degradation of 2,4-dichloroaniline occurred during short term incubations (up to 3 days) in die-away tests using an estuarine water from the Skidaway River in Georgia(4).

A BCF of 94.7 was experimentally determined for 2,4-dichloroaniline under static conditions in a closed basin with 60 male zebra fish and 5000 ml of carbon filtered tap water(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).

The Koc of 2,4-dichloroaniline is 525(1). According to a classification scheme(2), this Koc value suggests that 2,4-dichloroaniline will have low mobility in soil. A Koc of 3930 was measured at pH 6.5 using a colloidal-sized fraction of dissolved organic carbon isolated from groundwater monitoring wells(3). In soil column leaching studies simulating waste leaching from landfill sites, 2,4-dichloroaniline exhibited moderate leaching when leached in combination with leachate from domestic landfill sites(4). Aromatic amines (such as various chloro- and dichloroaniline isomers) have been observed to undergo rapid and reversible covalent bonding with humic materials in aqueous solution. The initial bonding reaction is followed by a slower and much less reversible reaction believed to represent the addition of the amine to quinoidal structures in humic material followed by oxidation of the product to give an amino-substituted quinone(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.
