Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)

Use water spray, powder.

Fresh air, rest.

Remove contaminated clothes. Rinse skin with plenty of water or shower.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth.

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

SMALL SPILLS AND LEAKAGE: If a spill of this chemical occurs, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with acetone and transfer the dampened material to a suitable container. Use absorbent paper dampened with acetone to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with acetone followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 72(SRC), determined from a log Kow of 0.88(2) and a regression-derived equation(3), indicates that 4-nitro-1,2-diaminobenzene is expected to have high mobility in soil(SRC). However, aromatic amines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(4), suggesting that mobility may be much lower in some soils(SRC). Volatilization of 4-nitro-1,2-diaminobenzene from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 7.4X10-12 atm-cu m/mole(SRC), using a fragment constant estimation method(5). 4-Nitro-1,2-diaminobenzene is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.1X10-4 mm Hg(SRC), determined from a fragment constant method(6). Information is not available regarding the biodegradation potential of 4-nitro-1,2-diaminobenzene; however, 33% percent of structurally-related o-phenylenediamine was removed over 120 hours based on chemical oxygen demand measurements and using an activated sludge inoculum(7).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 72(SRC), determined from a log Kow of 0.88(2) and a regression-derived equation(3), indicates that 4-nitro-1,2-diaminobenzene is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 7.4X10-12 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(5), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Information is not available regarding the biodegradation potential of 4-nitro-1,2-diaminobenzene; however, 33% percent of structurally-related o-phenylenediamine was removed over 120 hours based on chemical oxygen demand measurements and using an activated sludge inoculum(7).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 4-nitro-1,2-diaminobenzene, which has an estimated vapor pressure of 1.1X10-4 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase 4-nitro-1,2-diaminobenzene is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 17 hours(SRC), calculated from its rate constant of 2.2X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase 4-nitro-1,2-diaminobenzene may be removed from the air by wet or dry deposition(SRC). 4-Nitro-1,2-diaminobenzene absorbs light at wavelengths above 290 nm(4) and therefore may be susceptible to direct photolysis by sunlight(SRC).

/OTHER TERRESTRIAL SPECIES/ ... The toxicity of 10 benzamines was tested by the well diffusion assay technique against 18 common bacterial species including the nitrogen-fixing bacterium Azotobacter vinelandii. p-Phenylenediamine was found to be inhibitory to the growth of Aeromonas hydrophila and Pseudomonas fluorescens. o-Phenylenediamine was inhibitory to Escherichia coli, Klebsiella pnemoniae, Salmonella enteritidis, and Shigella sonnei. 2,5-Diaminotoluene was inhibitory to the growth of P. fluorescens and Streptococcus mitis.

The Koc of 4-nitro-1,2-diaminobenzene is estimated as 72(SRC), using a log Kow of 0.88(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 4-nitro-1,2-diaminobenzene is expected to have high mobility in soil. However, aromatic amines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(4), suggesting that mobility may be much lower in some soils(SRC).

The teratogenicity of 2-amino-4-nitroaniline (ANA) was evaluated in pregnant outbred albino CD-1 mice (118/group, 11-47/treated group) exposed to ANA by subcutaneous injection at dose levels of 0, 16, 32, 64, 128, 256, 512, 768 or 1024 mg/kg/day on gestation days (GD) 6-15. The mice were sacrificed on GD 18. Significant dose-related differences between treated and control animals were observed in the following: decreased weight gain of dams during pregnancy and average fetal weight (256 mg/kg/day and above dose levels), decreased average number of live fetuses/dam (768 mg/kg/day level), increased mortality (6 of 36 and 7 of 37 at dose levels of 768 and 1024 mg/kg/day, respectively, versus no treatment related mortalities in lower dose levels or in controls), increased average percentage malformed fetuses (256 mg/kg/day and above), increased cleft palate (the major malformation overall, significant by Fisher's Exact Test (FE Test) for doses of 256 mg/kg/day and above), malformed and missing major blood vessels, including missing subclavian artery and aortic arch (512 and 1024 mg/kg/day levels), and increased incidence of white lesions in the left ventricle of the fetal heart which tested positive for calcium (512 mg/kg/day and above).

4-Nitro-o-phenylenediamine (NOP) is a powerful direct-acting mutagen which demonstrates significant enhancement in mutagenicity when exposed to plant enzymatic systems. Evidence implicating the involvement of peroxidactic oxidation in NOP activation has been obtained from plant-cell suspension and isolated enzyme experiments. Using selected cytochrome P450 and peroxidase enzyme inhibitors in conjunction with Salmonella typhimurium strain TA98 and intact plant-cell activating systems as well as isolated horseradish peroxidase enzyme /the authors/ have further investigated NOP activation by plant systems. The activation of NOP by both plant cells and by horseradish peroxidase was suppressed by the P450 inhibitors methimazole and (+)-catechin and by the peroxidase inhibitors diethyldithiocarbamate and potassium cyanide, but was not suppressed by the P450 inhibitors metyrapone and 7,8-benzoflavone. In addition, peroxidase enzymatic activity was measured and found to be inhibited by methimazole, diethyldithiocarbamate and potassium cyanide but not by (+)-catechin. The data strongly support the involvement of exogenous peroxidase in the plant activation of NOP, but point to a complex metabolic system that requires multistep processing before full mutagenic potential of the plant-activated component of NOP is expressed.
