Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]: As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above. FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

SMALL SPILLS AND LEAKAGE: Should a spill occur while you are handling this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with 60-70% ethanol and transfer the dampened material to a suitable container. Use absorbent paper dampened with 60-70% ethanol to pick up any remaining material. Seal the absorbent paper, and any of your clothes, which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with 60-70% ethanol 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. STORAGE PRECAUTIONS: You should protect this material from exposure to light, and store it in a refrigerator. (NTP, 1992)

Skin: Wear appropriate personal protective clothing to prevent skin contact. Eyes: Wear appropriate eye protection to prevent eye contact. Wash skin: The worker should wash daily at the end of each work shift. Remove: Work clothing that becomes wet or significantly contaminated should be removed and replaced. Change: Workers whose clothing may have become contaminated should change into uncontaminated clothing before leaving the work premise. (NIOSH, 2016)|Use gloves and goggles to avoid contact with skin and eyes.

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.|The worker should wash daily at the end of each work shift.|Work clothing that becomes wet or significantly contaminated should be removed and replaced.|Workers whose clothing may have become contaminated should change into uncontaminated clothing before leaving the work premises.

This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. Diphenylamine is produced, as an intermediate or a final product, by process units covered under this subpart.

N,N-Diphenylamine's production and use in the manufacture of dyes, stabilizing nitrocellulose explosives, and celluloid(1) may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1,900(SRC), determined from a log Kow of 3.50(2) and a regression-derived equation(3), indicates that N,N-diphenylamine is expected to have low mobility in soil(SRC). Volatilization of N,N-diphenylamine from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.7X10-6 atm-cu m/mole(SRC) derived from its vapor pressure, 6.7X10-4 mm Hg(4), and water solubility, 53 mg/liter(5). N,N-Diphenylamine is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(4). N,N-Diphenylamine is not expected to biodegrade in soil based on aqueous screening tests(6). N,N-Diphenylamine, present at 30 mg/l, reached 0% of its theoretical BOD in 2 weeks using an activated sludge innoculum at 100 mg/l and the Japanese MITI test(6).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1,900(SRC), determined from a log Kow of 3.50(2) and a regression-derived equation(3), indicates that N,N-diphenylamine is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 2.7X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 6.70X10-4 mm Hg(4), and water solubility, 53 mg/l(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 9.4 and 107 days, respectively(SRC). According to a classification scheme(6), BCFs ranging from 51 to 253(7), suggests bioconcentration in aquatic organisms is moderate(SRC). N,N-Diphenylamine was found to be not readily biodegradable in aqueous screening tests(7). N,N-Diphenylamine, present at 30 mg/l, reached 0% of its theoretical BOD in 2 weeks using an activated sludge innoculum at 100 mg/l and the Japanese MITI test(7).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), N,N-diphenylamine, which has a vapor pressure of 6.7X10-4 mm Hg at 25 °C(2) is expected to exist solely as a vapor in the ambient atmosphere(SRC). Vapor-phase N,N-diphenylamine 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 1.9 hours(SRC), calculated from its rate constant of 2.0X10-10 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3).

The rate constant for the vapor-phase reaction of N,N-diphenylamine with photochemically-produced hydroxyl radicals has been estimated as 2.0X10-10 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 1.9 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). N,N-Diphenylamine is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups(2) nor to directly photolyze due to the lack of absorption in the environmental UV spectrum (>290 nm)(SRC).

151.36|BCFs ranging from 101 to 242 and 51 to 253 (species unidentified) were measured using 0.1 and 0.01 mg/liter of N,N-diphenylamine, respectively, and a 8-week study period(1). According to a classification scheme(2), these BCFs suggest the potential for bioconcentration in aquatic organisms is moderate(SRC).

602.56 L/kg|The Koc of N,N-diphenylamine is estimated as 1,900(SRC), using a log Kow of 3.50(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that N,N-diphenylamine is expected to have low mobility in soil(SRC).

The Henry's Law constant for N,N-diphenylamine is estimated as 2.7X10-6 atm-cu m/mole(SRC) derived from its vapor pressure, 6.7X10-4 mm Hg(1), and water solubility, 53 mg/l(2). This Henry's Law constant indicates that diphenylamine is expected to volatilize from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(3) is estimated as 9.4 days(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 107 days(SRC). N,N-Diphenylamine is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

GROUNDWATER: N,N-Diphenylamine was detected in 4 groundwater samples (1 up-flow and 3 down-flow) at an abandoned ammunition site in Germany(1).

N,N-Diphenylamine was found in domestic and imported apples at avg concns of 0.275 ppm (max, 8.1 ppm; detections, 223 out of 769) and 0.232 ppm (max, 5.9 ppm; detections, 402 out of 1,062), respectively(1). N,N-Diphenylamine was detected in fruits and vegetables (15 of 3,962 sample) at concns between <0.01 and <5 ug/g from samples collected in Ontario, Canada between the years 1991 to 1995(2). As part of the Danish Pesticide Monitoring Program conducted between the years 1995-96, N,N-diphenylamine was detected in 5 of 96 apples and 1 of 33 pear samples(3). In selected agricultural commodities available in Canada, the concn of N,N-diphenylamine ranged from <0.05 to 2.0 ppm in 16 of 676 samples analyzed(4).

The NOES Survey does not include farm workers. Occupational exposure to N,N-diphenylamine may occur through dermal contact with this compound at workplaces where N,N-diphenylamine is produced or used(SRC). Monitoring data indicate that the general population may be exposed to N,N-diphenylamine via ingestion of food, and dermal contact with consumer products containing N,N-diphenylamine (SRC).

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. SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment. INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing. INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)|(See procedures)
