Description of necessary first-aid measures
Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.

Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms/effects, acute and delayed
Lowest toxic dose with skin effect is 14 mg/kg. Irritant to skin and eyes. (EPA, 1998)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as 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.

Bioaccumulative potential
An estimated BCF of 23 was calculated for N,N-dimethyl-p-benzenediamine(SRC), using an estimated log Kow of 1.25(1) and a regression-derived equation(2). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low.
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for the unprotonated form of N,N-dimethyl-p-benzenediamine can be estimated to be 38(SRC). According to a classification scheme(2), this estimated Koc value suggests that N,N-dimethyl-p-benzenediamine is expected to have very 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(3,4); therefore, mobility may be much lower in some soils(SRC). The pKa of N,N-dimethyl-p-benzenediamine is 6.59(5), indicating that this compound will exist partially in the cation form in the environment and cations generally adsorb to organic carbon and clay more strongly than their neutral counterparts.
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
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.
