| 소화 | Fire Extinguishing Agents Not to Be Used: Water or foam may cause frothingUse water spray, powder, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water. |
| 응급 조치 | Fresh air, rest. Refer for medical attention.Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.Rinse mouth. Give one or two glasses of water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention . |
| 응급 처치 | 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. |

| 비화재 누출 대응 | 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. |
| 누출 처리 | Personal 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. Carefully collect remainder. Then store and dispose of according to local regulations. |
| Preventive Measures | SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants. |

They had increased respiration and hemorrhaging, were darkly colored, and lost equilibrium prior to death. |
| 환경 거동 | TERRESTRIAL FATE: When released to soil, 2,4-dinitroaniline may undergo covalent chemical bonding with humic materials which can result in its chemical alteration to a latent form and tight adsorption. When covalently bound in this latent form, leaching in soil systems is not generally expected to occur. This covalent bonding proceeds in two stepsa rapid and reversible bonding followed by a slower and much less reversible reaction(1,SRC). Leaching in soil may be possible prior to the occurrence of the slower bonding reaction. In the absence of covalent bonding, moderate leaching may be possible (estimated Koc value of 240)(3,4,SRC). Although one biological screening study showed no biodegradation in river and sea water(2), insufficient data are available to assess the relative importance of biodegradation of 2,4-dinitroaniline in soil(SRC).AQUATIC FATE: By analogy to the aromatic amine chemical class(2), 2,4-dinitroaniline in the water column may be susceptible to photooxidation via hydroxyl and peroxy radicals(SRC). Aromatic amines have also been shown to undergo covalent bonding with humic materials in the water column and in sediment(1)partitioning from the water column to sediment and suspended material may therefore be important(SRC). Although one biological degradation study found evidence of no microbial degradation(3), insufficient data are available to assess the relative importance of biodegradation of 2,4-dinitroaniline in water. An estimated BCF value of 15(4,SRC) suggests that it will not bioconcentrate significantly in aquatic organisms(SRC). Aquatic hydrolysis and volatilization do not appear to be environmentally important(SRC).ATMOSPHERIC FATE: Based upon an estimated vapor pressure of 5.94X10-7 mm Hg at 25 °C(1), 2,4-dinitroaniline may exist in both the vapor and the particulate-phase in the ambient atmosphere(2,SRC). It is degraded relatively rapidly in the vapor phase in an average ambient atmosphere by reaction with photochemically produced hydroxyl radicals at an estimated half-life of about 17.7 hr(3,SRC). |
| 유해 작용 | Occupational hepatotoxin - Secondary hepatotoxins: the potential for toxic effect in the occupational setting is based on cases of poisoning by human ingestion or animal experimentation. |
| 노출 경로 | The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. |
| Signs and Symptoms | Cough. Sore throat.MAY BE ABSORBED! Redness. Pain. |
| ICSC Environmental Data | The substance is harmful to aquatic organisms. |
| Soil Adsorption/Mobility | Aromatic amines have been observed to undergo rapid and reversible covalent bonding with humic materials in aqueous solutionthe initial bonding reaction is followed by a slower and much less reversible reaction believed to represent the addition of the amine to quinoidal structures followed by oxidation of the product to give an amino-substituted quinonethese processes represent pathways by which aromatic amines may be converted to latent forms in the biosphere(3). In the absence of covalent bonding, a Koc of approximately 240 can be estimated for 2,4-dinitroaniline based on an estimated log Kow of 1.84(2) and a recommended regression-derived equation(1,SRC)this Koc value suggests medium soil mobility(4). |
| Artificial Pollution Sources | 2,4-Dinitroaniline may be released to the environment during its production and use in the preparation of azo dyes(1,SRC). |
| Environmental Biodegradation | 2,4-Dinitroaniline at an initial concn of 100 ppm showed no biodegradation in river and sea water after 3 days using a cultivation test method(1). |
| Environmental Bioconcentration | Based on an estimated log Kow of 1.84(2), the bioconcentration factor (BCF) for 2,4-dinitroaniline can be estimated to be about 15 from a recommended regression-derived equation(1,SRC). This BCF value suggests that bioconcentration in aquatic organisms may not be significant(SRC). |
| Volatilization from Water/Soil | The Henry's Law constant for 2,4-dinitroaniline can be estimated to be approximately 1.51X10-10 atm-cu m/mole at 25 °C using a chemical structure estimation method(2,SRC). This value of Henry's Law constant suggests that 2,4-dinitroaniline is essentially nonvolatile from water(1). |
