Administration of oxygen may be needed. Rinse mouth. Do NOT induce vomiting. Rest. Refer immediately for medical attention. See Notes.
4.2 Most important symptoms/effects, acute and delayed
It is classified as very toxic. Probable oral lethal dose in humans is 50-500 mg/kg for a 150 lb. person. Aniline poisoning is characterized by methemoglobin formation in the blood and resulting cyanosis or blue skin. The formation of methemoglobin interferes with the oxygen-carrying capacity of the blood. The approximate minimum lethal dose for a 150 lb. human is 10 grams. Serious poisoning may result from ingestion of 0.25 mL. People at special risk include individuals with glucose-6-phosphate-dehydrogenase deficiency and those with liver and kidney disorders, blood diseases, or a history of alcoholism. (EPA, 1998)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Aniline and related compounds/
5.1 Extinguishing media
Suitable extinguishing media
Use alcohol foam extinguishers. Vapors are heavier than air and will collect in low areas. Vapors may travel long distances to ignition sources and flashback. Vapors in confined areas may explode when exposed to fire. Storage containers and parts of containers may rocket great distances, in many directions. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Notify local health and fire officials and pollution control agencies. Fight fire from maximum distance. Dike fire control water for later disposal and do not scatter material. If a leak or spill has not ignited, use water spray to control vapors. From a secure, explosion-proof location, use water spray to cool exposed containers. If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors or shows any signs of deforming), withdraw immediately to a secure position ... The only respirators recommended for fire fighting are self-contained breathing apparatuses that have full facepieces and are operated in a pressure-demand or other positive-pressure mode.
5.2 Specific hazards arising from the chemical
Combustion can produce toxic fumes including nitrogen oxides and carbon monoxide. Aniline vapor forms explosive mixtures with air. It is incompatible with strong oxidizers and strong acids and a number of other materials. Avoid heating. Hazardous polymerization may occur. Polymerizes to a resinous mass. (EPA, 1998)
5.3 Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.
6.Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures
Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.
6.2 Environmental precautions
Evacuate danger area! Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
6.3 Methods and materials for containment and cleaning up
Wear breathing apparatus, eye protection, laboratory coat, and butyl rubber gloves. Cover the spill with a 1:1:1 mixture by weight of sodium carbonate or calcium carbonate, clay cat litter (bentonite), and sand. When the aniline has been absorbed, scoop the mixture into a plastic pail and add enough water to dissolve the sodium carbonate. Allow the solids to settle and decant the liquid to another container. Discard the solids with the normal refuse. To the liquidd, slowly (frothing will occur) add 6 M sulfuric acid to pH 2. Stir into the acidified solution sufficient solid potassium permanganate so that the liquid is purple (a drop of the liquid on filter paper will show a purple ring). Allow the mixture to stand at room temperature for 48 hours, and then neutralize with solid sodium carbonate (frothing will occur), or with a 10% aqueous solution of sodium hydroxide. Add solid sodium bisulfite until the solution is colorless. Decant the clear liquid into the drain and discard any brown solid with normal refuse.
7.Handling and storage
7.1 Precautions for safe handling
Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.
7.2 Conditions for safe storage, including any incompatibilities
Separated from strong oxidants, strong acids and food and feedstuffs. Well closed. Provision to contain effluent from fire extinguishing. Store in an area without drain or sewer access.Aniline is slightly corrosive to some types of metal. So all amphoteric materials such as aluminum, copper, tin, zinc, and alloys containing one of these metals (brass, bronze) are not suitable for the handling of aniline, as they are corroded by it. For normal applications carbon steel or cast iron are appropriate materials for the aniline handling or storage. Only if discoloration must be kept to minimum, aniline should be stored and transported in stainless steel equipment with proper nitrogen blanketing.

Classification of carcinogenicity: Overall summary evaluation of carcinogenic risk to humans is Group 3: The agent is not classifiable as to its carcinogenicity to humans.
No information is available on the reproductive or developmental effects of aniline in humans. Birth defects were observed in animals given aniline by gavage (placing the chemical experimentally in the stomachs of the animals). The total number of offspring in mice given aniline by gavage was lower than in the control group even though the average number of offspring per litter was not affected. However, some of the pregnant mice treated with aniline died during pregnancy. Survival of offspring in the aniline-treated group was decreased.

12.2 Persistence and degradability
AEROBIC: Aniline is a benchmark chemical for aerobic biodegradability tests and there are abundant data on its biodegradation. Degradation is frequently 90-100% in laboratory tests utilizing activated sludge or sewage seed lasting from 3 to 28 days with acclimation not always being required(1-14).
12.3 Bioaccumulative potential
The measured log BCF for aniline in three species of fish was 0.78(1) and less than 1(2,4). According to a classification scheme(5), these measured BCF values suggests the potential for bioconcentration in aquatic organisms is low(SRC). The log BCF for algae was reported as 0.6(2,3).
12.4 Mobility in soil
Primary anilines may bind to soils due to the ability of the aromatic amino group to form covalent bonds with humic and fulvic material in soils(1). The Koc of aniline in 5 European soils was reported in the range of 43.8-497.7(2). The Koc values in 2 silt loams were 130 and 410 with the higher value occurring in the more acidic soil(3). The Koc of aniline in colloidal organic carbon from groundwater (pH 6.5) was reported as 3,870(4). The adsorption constant for adsorption to H-montmorillonite (pH 8.35) and Na-montmorillonite (pH 6.8) is 1,300 and 130(5). The Koc of aniline in 3 silt-clay loams were 269 (pH 4.4), 48 (pH 6.5) and 16 (pH 7.2)(6). A mean Koc value of 55 was determined for aniline in 4 sewage sludges(7). The Koc in five second-generation reference EUROSOILS was 8, 32, 19, 27 and 137(8). According to a classification scheme(9), this Koc data suggests that aniline may have very high to medium mobility in soil. The pKa of aniline is 4.60(10, indicating that this compound will partially exist in the protonated (cation) form; however, in the pH range between pH5 and pH9, aniline will exist primarily in the non-protonated form; in the protonated form in the environment, cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(11). In a sorption study using pond sediment from Cherokee Park pond in Athens GA, the sorption kinetics of aniline were characterized by a rapid initial loss of aniline from the aqueous phase followed by a much slower rate of disappearance. The initial sorption was a reversible cation-exchange followed by a slower covalent-binding. It was shown that at pH values greater than the pKa, sorption kinetics were slower than at pH3.75 (rate constants of 4.53-7.95/hr above versus 13.3 below)(12).
12.5 Other adverse effects
no data available
