5.Fire-fighting measures 5.1 Extinguishing media Suitable extinguishing mediaThis chemical is a combustible solid. Use dry chemical, carbon dioxide, water spray, or alcohol foam extinguishers. Poisonous gases including sulfur dioxide and nitrogen oxides are produced in fire. 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. If employees are expected to fight fires, they must be trained and equipped in OSHA 1910.156.
5.2 Specific hazards arising from the chemicalSpecial Hazards of Combustion Products: Toxic oxides of nitrogen may form in fire. Behavior in Fire: Melts and burns (USCG, 1999)
5.3 Special protective actions for fire-fightersWear self-contained breathing apparatus for firefighting if necessary.
6.Accidental release measures 6.1 Personal precautions, protective equipment and emergency proceduresUse 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 precautionsPersonal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water.
6.3 Methods and materials for containment and cleaning up1. Ventilate area of spill. 2. For small quantities, sweep onto paper or other suitable material, place in an appropriate container & burn in a safe place (such as a fume hood). Large quantities may be reclaimed; however, if this is not practical, dissolve in a flammable solvent (such as alcohol) & atomize in a suitable combustion chamber equipped with an appropriate effluent gas cleaning device.
7.Handling and storage 7.1 Precautions for safe handlingAvoid 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.

Skin protectionWear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.

10.3 Possibility of hazardous reactionsCombustible when exposed to heat or flame.Dust explosion possible if in powder or granular form, mixed with air.P-NITROANILINE may react vigorously with sulfuric acid above 200°C. It may also react with sodium hydroxide at 130°C. Under pressure, it may produce an explosive compound. It is incompatible with strong oxidizers and strong reducing agents. It is capable of explosive decomposition with strong initiators. It will attack some forms of plastics, rubber and coatings.
10.4 Conditions to avoidno data available
10.5 Incompatible materialsAn ammonical soln of 4-nitroaniline containing ammonium chloride was being treated with 50% sodium hydroxide soln to displace ammonia. In error, double the amt required to give usual 10% of free alkali was added, & during subsequent degassing operation (heating to 130°C under pressure, followed by depressuring to vent ammonia), complete conversion to sodium 4-nitrophenoxide occurred. ... /When/ separated by centrifuging, it was then heated to dry ... when it decomposed violently & was ejected through the vessel opening. ... Some of the tautomeric aci-nitroquinonoid salt may have been produced during the drying operation.

P-NITROANILINE AT CONCN 250-1000 MG/L WAS DEGRADED BY A MIXT OF PSEUDOMONAS FLUORESCENS & BACILLUS VALINOVORUS.
12.3 Bioaccumulative potentialIn a 6-week bioconcentration test, the BCF of 4-nitroaniline was 2.9-3.6 at a concentration of 0.5 mg/L and <10 at a concentration of 0.05 mg/L(1). In a bioconcentration study using zebrafish and a 4-nitroaniline concentration of 0.21 umol/L, the BCF was measured to be 4.4(2). According to a classification scheme(3), these experimental BCF values suggest bioconcentration in aquatic organisms is low (SRC).
12.4 Mobility in soil4-Nitroaniline has measured log Koc values of 1.78(1) and 1.88(2) and log Kom values of 1.49(3) and 1.64(4). These values correspond to Koc values of 60, 76, 54 and 75, respectively. 4-Nitroaniline has also been observed to have a Koc of 87(5). According to a classification scheme(6), these Koc values suggest that 4-nitroaniline is expected to have high mobility in soil. 4-Nitroaniline was found to have a Kd value of 13.5 L/kg in homoionic K+ Montmorillonite type soil(7). However, anilines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(8,9), suggesting that mobility may be much lower in some soils(SRC). 4-Nitroaniline had small and scattered amounts of irreversible binding over a 20 hour experiment(10).
12.5 Other adverse effectsno data available
13.Disposal considerations 13.1 Disposal methods ProductThe material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing.
