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 with pure water for at least 15 minutes. 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
ACUTE/CHRONIC HAZARDS: Toxic. (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. Nitrates, nitrites, and related compounds
SECTION 5: Firefighting measures
Suitable extinguishing media
A fire in your laboratory involving this chemical may produce dangerous vapors. Please evacuate the area immediately. As a firefighter, you should be equipped with full-body protective clothing and a self-contained breathing apparatus. You should extinguish this fire with a dry chemical, carbon dioxide or halon extinguisher. You should avoid using a water or foam extinguisher as they may cause spattering. (NTP, 1992)

Possibility of hazardous reactions
N-NITROSODI-N-PROPYLAMINE is a nitrated azo derivative. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.

Persistence and degradability
Enrichment cultures from soil and sewage failed to produce any organisms capable of metabolizing N-nitrosodi-n-propylamine(1). Another investigator found 3 types of microorganisms (a fungus, bacterium and yeast) able to degrade N-nitrosodi-n-propylamine(4). In another study, settled domestic wastewater was used as the inoculum for static biodegradation tests on N-nitrosodi-n-propylamine(2). The biodegradation after 7 days incubation each in the original culture and first, second and third subcultures at an initial N-nitrosodi-n-propylamine concn of 5 mg/l was 27%, 37%, 47% and 50%, respectively; at an initial concn of 10 mg/l the degradation was 0%, 8%, 40% and 40%, respectively(2). In municipal activated sludge treatment plants, N-nitrosodi-n-propylamine influent concns of 0.5 and 6.7 ug/l were reduced by 88 and 99%, respectively(3). However, 0% removal of N-nitrosodi-n-propylamine was reported at two industrial activated sludge treatment plants with an average N-nitrosodi-n-propylamine influent concn of 11 mg/l(3). No biodegradation of N-nitrosodi-n-propylamne occurred in die-away tests in Cayuga Lake water over a period of 3.5 months and a lag of nearly 30 days was observed before its slow disappearance from soil(1). It appeared to be degraded very slowly in sewage but was unaffected by anaerobic organisms of bog sediment(5).
Bioaccumulative potential
A BCF of 6 was estimated for N-nitrosodi-n-propylamine (SRC), using a log Kow of 1.36(1,SRC) and a recommended regression-derived equation(2). According to a recommended classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms would be low(SRC).
Mobility in soil
The Koc of N-nitrosodi-n-propylamine is estimated to be 130(SRC), using a measured log Kow of 1.36(1) and regression-derived equation(2,SRC). According to a recommended classification scheme(3), this Koc value suggests that N-nitrosodi-n-propylamine will have high mobility in soil(SRC). A laboratory study found that N-nitrosodi-n-propylamine leached under heavy simulated rainfall; however, it did not leach below 20 cm in a field study(4). It was inferred that although N-nitrosodi-n-propylamine's high water solubility caused it to move with resident soil moisture, it dissipated readily before extensive leaching occurred(4). N-Nitrosodi-n-propylamine's sludge-water distribution constant is 100(5).
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.
