When heated to decomposition, this compound emits irritating and/or toxic gases and fumes of carbon monoxide, carbon dioxide and oxides of nitrogen. (NTP, 1992)

Indication of immediate medical attention and special treatment needed, if necessary

For immediate first aid: Ensure that adequate decontamination has been carried out. If victim is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep victim quiet and maintain normal body temperature. Obtain medical attention. Organic bases, amines, and related compounds

SECTION 5: Firefighting measures

Suitable extinguishing media

Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]: SMALL FIRE: Dry chemical, CO2 or water spray. LARGE FIRE: Dry chemical, CO2, alcohol-resistant foam or water spray. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal; do not scatter the material. FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)

SECTION 12: Ecological information

Toxicity

  • Toxicity to fish: LC50 - Oncorhynchus mykiss (previous name: Salmo gairdneri) - 512 mg/L - 96 h.
  • Toxicity to daphnia and other aquatic invertebrates: LC50 - Gammarus fasciatus - 4.6 mg/L - 96 h.
  • Toxicity to algae: NOEC - Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum) - 0.915 mg/L - 96 h.
  • Toxicity to microorganisms: 30% reduction in respiration rate - activated sludge of a predominantly industrial sewage - 100 mg/L - 30 min. Remarks:Respiration rate.

Persistence and degradability

1,3-Benzenediamine was observed to degrade 60% after 5 days at concn levels of 25 to 30 ppm using an acclimated activated sludge inoculum(1). However at 50 ppm 1,3-benzenediamine was reported to be toxic to 3 unacclimated activated sludges(2). Soil microflora did not cleave the benzene ring of 1,3-benzenediamine in 64 days(3). 1,3-Benzenediamine, present at an initial concn of 100 mg/l, reached 2% of its theoretical BOD in 4 weeks using an activated sludge inoculum(4).

Bioaccumulative potential

An estimated BCF value of 0.33 was calculated for 1,3-benzenediamine(SRC), using an estimated log Kow of -0.33(1) and a recommended regression-derived equation(2). BCF values of 1.3 to 4.6 and <1.6 to 24 were measured for 1,3-benzenediamine in carp at 2 and 0.2 mg/l, respectively(3). According to a classification scheme(4), these BCF values suggest that bioconcentration in aquatic organisms is low(SRC).

Mobility in soil

The Koc of 1,3-benzenediamine is estimated as approximately 16(SRC), using a measured log Kow of -0.33(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that 1,3-benzenediamine is expected to have very high mobility in soil(SRC). However, anilines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(4,5); therefore, mobility may be much lower in some soils(SRC).

Other adverse effects

no data available

SECTION 13: Disposal considerations

Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
