In case of eye contact
Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.
If swallowed
Rinse mouth. Refer immediately for medical attention.
4.2 Most important symptoms/effects, acute and delayed
Absorption of toxic quantities by any route causes cyanosis (blue discoloration of lips, nails, skin); nausea, vomiting, and coma may follow. Repeated inhalation of low concentrations may cause pallor, low-grade secondary anemia, fatigability, and loss of appetite. Contact with eyes causes irritation. (USCG, 1999)
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.Fire-fighting measures
5.1 Extinguishing media
Suitable extinguishing media
Use dry chemical, carbon dioxide, or 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. Containers may explode in 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. 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
Special Hazards of Combustion Products: Toxic oxides of nitrogen and flammable vapors may form in fire. (USCG, 1999)
5.3 Special protective actions for fire-fighters

12.2 Persistence and degradability
AEROBIC: Biodegradation results of 2-aminotoluene showed: 100% degradation in 6 hr using an activated sludge inoculum(1); 56% of theoretical BOD utilized in 5 days with a sewage seed(2); 100% of theoretical BOD in 8 days using an activated sludge inoculum acclimated to aniline(3); 97.7% removal in 5 days with activated sludge(4). Using activated sludge from the wastewater treatment plant used to treat effluent known to contain 2-aminotoluene, 92% chemical oxygen demand removal was obtained in a 24 hr incubation with the chemical(5). 2-Aminotoluene, present at 100 mg/L, reached 65% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(6). Complete degradation was obtained in 64 days with a soil inoculum(7). Six laboratories obtained >90% degradation of 2-aminotoluene in 7 days in two screening tests designed to simulate surface waters and polluted river water(8). 500 ppm of 2-aminotoluene completely degraded in 3 days in a Chernozem soil, leaving degradation products that persisted for over 90 days(9). Approximately 90% of 2-aminotoluene was degraded in 15 days under aerobic conditions using an inoculum prepared from water samples collected from a polluted river; less than 20% degradation was observed in 15 days using an inoculum prepared from water samples collected from a non-polluted river(10). 2-Aminotoluene, present at 2 mg/L, reached 41% of its theoretical BOD in 5 days using water from the Songhua River in China as an inoculum(11). The mean biodegradation rate constant and half-life measured for 50 ug/L 2-aminotoluene in a sludge inoculum were 8.8X10-6/sec and 22 hours, respectively(12). These data indicate that biodegradation of 2-aminotoluene will be an important environmental fate process(SRC).
12.3 Bioaccumulative potential
An estimated BCF of 3.5 was calculated for 2-aminotoluene(SRC), using a log Kow of 1.32(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
The measured partition coefficient between sediment and water for 2-aminotoluene ranged from 40 to 250(1). According to a classification scheme(2), these Koc values suggest that 2-aminotoluene is expected to have very high to moderate mobility in soil. A group of investigators found the movement of toluidines through clay (montmorillonite) was not inhibited by sorption(3). The pKa of 2-aminotoluene is 4.44(4), indicating that this compound will exist partially in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). Aromatic amines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(6,7), suggesting that mobility may be much lower in some soils(SRC).
12.5 Other adverse effects
