Dipikrylamin

If material on fire or involved in fire: Dangerously explosive. Do not fight fires in a cargo of explosives. Evacuate area and let burn.

Wear positive pressure self-contained breathing apparatus when fighting fires involving this material.

Evacuation: If the material is on fire or involved in fire consider evacuation of one (1) mile radius.

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity 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 and plant life; and conformance with environmental and public health regulations.

If material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material wet. Wet spilled material before picking it up. Do not attempt to sweep up dry material.

Personnel protection: Avoid breathing dusts, and fumes from burning material ... Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water.

Excerpt from ERG Guide 112 [Explosives - Division 1.1, 1.2, 1.3 or 1.5]:

Wear appropriate chemical protective gloves and goggles.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 1.1X10+6(SRC), determined from a structure estimation method(2), indicates that 2,2',4,4',6,6'-hexanitrodiphenylamine is expected to be immobile in soil(SRC). Volatilization of 2,2',4,4',6,6'-hexanitrodiphenylamine from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.3X10-17 atm-cu m/mole(SRC), using a fragment constant estimation method(3). 2,2',4,4',6,6'-Hexanitrodiphenylamine is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 6.3X10-14 mm Hg at 25 °C(SRC), determined from a fragment constant method(4). Biodegradation data in soil were not available(SRC, 2010).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 1.1X10+6(SRC), determined from a structure estimation method(2), indicates that 2,2',4,4',6,6'-hexanitrodiphenylamine 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 2.3X10-17 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(5), an estimated BCF of 76(SRC), from an estimated log Kow of 3.4(6) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is moderate(SRC), provided the compound is not metabolized by the organism(SRC). Biodegradation data in water were not available(SRC, 2010).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 2,2',4,4',6,6'-hexanitrodiphenylamine, which has an estimated vapor pressure of 6.3X10-14 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely in the particulate phase in the ambient atmosphere. Particulate-phase 2,2',4,4',6,6'-hexanitrodiphenylamine may be removed from the air by wet or dry deposition(SRC). 2,2',4,4',6,6'-Hexanitrodiphenylamine does not contain chromophores that absorb at wavelengths >290 nm(3) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

/AQUATIC SPECIES/ Aqueous samples containing various explosives, their reduced metabolites, as well as related compounds were subjected to the luminescent bacterium Vibrio fischeri NRRLB-11177 to determine their ecotoxicological potential. As the most important parameter, the EC50 values of 24 test compounds were calculated. ... HEXYL must be classified in the category "very toxic to aquatic organisms"...

Using a structure estimation method based on molecular connectivity indices(1), the Koc of 2,2',4,4',6,6'-hexanitrodiphenylamine can be estimated to be 1.1X10+6(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2,2',4,4',6,6'-hexanitrodiphenylamine is expected to be immobile in soil.

An estimated BCF of 76 was calculated in fish for 2,2',4,4',6,6'-hexanitrodiphenylamine(SRC), using an estimated log Kow of 3.4(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC), provided the compound is not metabolized by the organism(SRC).

The Henry's Law constant for 2,2',4,4',6,6'-hexanitrodiphenylamine is estimated as 2.3X10-17 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that 2,2',4,4',6,6'-hexanitrodiphenylamine is expected to be essentially nonvolatile from water and moist soil surfaces(2). 2,2',4,4',6,6'-Hexanitrodiphenylamine is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 6.3X10-14 mm Hg(SRC), determined from a fragment constant method(3).

2,2',4,4',6,6'-Hexanitrodiphenylamine is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(1). 2,2',4,4',6,6'-Hexanitrodiphenylamine does not contain chromophores that absorb at wavelengths >290 nm(1) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

Occupational exposure to 2,2',4,4',6,6'-hexanitrodiphenylamine may occur through dermal contact with this compound at workplaces where 2,2',4,4',6,6'-hexanitrodiphenylamine is produced or used(SRC). Limited monitoring data indicate that the general populated may have been exposed to 2,2',4,4',6,6'-hexanitrodiphenylamine via ingestion of drinking water. Occupational exposure and general population exposure should be low or non-existent since 2,2',4,4',6,6'-hexanitrodiphenylamine is no longer produced or used as an explosive in the US(1).

GROUNDWATER: Water samples in the surroundings of a former munitions plant at Elsnig, Germany were found to contain 2,2',4,4',6,6'-hexanitrodiphenylamine at a concentration range of 13 to 215 ug/L(1).

2,2',4,4',6,6'-Hexanitrodiphenylamine's production and former use as a booster explosive may have resulted in its release to the environment through various waste streams. If released to air, an estimated vapor pressure of 6.3X10-14 mm Hg at 25 °C indicates 2,2',4,4',6,6'-hexanitrodiphenylamine will exist solely in the particulate phase in the atmosphere. Particulate-phase 2,2',4,4',6,6'-hexanitrodiphenylamine will be removed from the atmosphere by wet or dry deposition. 2,2',4,4',6,6'-Hexanitrodiphenylamine does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight. If released to soil, 2,2',4,4',6,6'-hexanitrodiphenylamine is expected to have no mobility based upon an estimated Koc of 1.1X10+6. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 2.3X10-17 atm-cu m/mole. Biodegradation data were not available. If released into water, 2,2',4,4',6,6'-hexanitrodiphenylamine is expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. An estimated BCF of 76 suggests the potential for bioconcentration in aquatic organisms is moderate. Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions.
