Description of first aid measures
If inhaledMove 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 and effects, both acute and delayed
Excerpt from ERG Guide 113 [Flammable Solids - Toxic (Wet/Desensitized Explosive)]: Some are toxic and may be fatal if inhaled, swallowed or absorbed through skin. Contact may cause burns to skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution. (ERG, 2016)
Excerpt from ERG Guide 112 [Explosives* - Division 1.1, 1.2, 1.3 or 1.5]: Fire may produce irritating, corrosive and/or toxic gases. (ERG, 2016)
Indication of any immediate medical attention and special treatment needed
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. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Dinitrophenol and Related Compounds
Extinguishing media
If material on fire or involved in fire: Dangerously explosive. Do not fight fires in a cargo of explosives. Evacuate area and let burn. Nitroguanidine, dry

Possibility of hazardous reactions
A very dangerous fire hazard when exposed to heat, flame, or by chemical reaction with oxidizers.Nitroalkanes, such as NITROGUANIDINE, range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. Nitroalkanes are milder oxidizing agents, but still react violently with reducing agents at higher temperature and pressures. Nitroalkanes react with inorganic bases to form explosive salts. The presence of metal oxides increases the thermal sensitivity of nitroalkanes. Nitroalkanes with more than one nitro group are generally explosive. Nitroalkanes are insoluble in water. Flammable/combustible material. May be ignited by heat, sparks or flames. DRIED OUT material may explode if exposed to heat, flame, friction or shock; Treat as an explosive. Mercury and silver complex salts of nitroguanidine are very impact sensitive.
Conditions to avoid
no data available
Incompatible materials
Can react vigorously with oxidizing materials and the derivatives can be explosive.
Hazardous decomposition products
Decomposes immediately on melting to form ammonia, water vapor, and solid products. The gases from the decomposition of nitroguanidine are far less erplosive than gases from other similar explosives.

- Toxicity to microorganisms: EC50 - activated sludge of a predominantly domestic sewage - > 300 mg/L - 3 h. Remarks:Respiration rate.
Persistence and degradability
AEROBIC: 1-Nitroguanidine is not susceptible to aerobic biodegradation in activated sludge, and was stable under sterile reducing conditions(1,2). No decomposition occurred under aerobic conditions in either batch or continuous cultures(2). After acclimation, nitroguanidine co-metabolizes to form nitrosoguanidine(2). 1-Nitroguanidine, present at 100 mg/L, reached less than 14% of its theoretical BOD after 4 weeks in an activated sludge inoculum at 30 mg/L in the Japanese MITI test(3).
Bioaccumulative potential
An estimated BCF of 3.2 was calculated in fish for 1-nitroguanidine(SRC), using a log Kow of -0.89(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of 1-nitroguanidine is estimated as 21(SRC), using a log Kow of -0.89(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1-nitroguanidine is expected to have very high mobility in soil. A sorption partition coefficient of <0.1 was calculated using sediments characterized by high surface areas(4).
Other adverse effects

Disposal methods
ProductThe 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.
