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 133 [Flammable Solids]: Fire may produce irritating and/or toxic gases. Contact may cause burns to skin and eyes. Contact with molten substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution. (ERG, 2016)
Indication of any immediate medical attention and special treatment needed
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

Specific Hazards Arising from the Chemical
Excerpt from ERG Guide 133 [Flammable Solids]: Flammable/combustible material. May be ignited by friction, heat, sparks or flames. Some may burn rapidly with flare-burning effect. Powders, dusts, shavings, borings, turnings or cuttings may explode or burn with explosive violence. Substance may be transported in a molten form at a temperature that may be above its flash point. May re-ignite after fire is extinguished. (ERG, 2016)
Advice for firefighters
Wear self-contained breathing apparatus for firefighting if necessary.
NFPA 704
| HEALTH | 2 | Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury (e.g. diethyl ether, ammonium phosphate, iodine) | |
| FIRE | 2 | Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur and multiple finely divided suspended solids that do not require heating before ignition can occur. Flash point between 37.8 and 93.3 °C (100 and 200 °F). (e.g. diesel fuel, sulfur) | |
| REACT | 0 | Normally stable, even under fire exposure conditions, and is not reactive with water (e.g. helium,N2) | |
| SPEC. HAZ. |
Personal precautions, protective equipment and emergency procedures
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.

Exposure controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures
Eye/face protectionWear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

Information on basic physicochemical properties
- Physical state
N-methyl-n'-nitro-n-nitrosoguanidine is a yellow powder. Melting point 244°F. Decomposes above 212°F. A suspected carcinogen. Extremely hazardous as a mutagen. Avoid skin contact and inhalation of of vapors. Usually stored frozen (below 32°F) in polyethylene bottles that are tightly closed and contained in a metal can. May decomposed during prolonged storage and develop sufficient pressure in a closed container to explode. Keep away from heat, sparks, and open flame.

Chemical stability
Pure cmpd is sensitive to light, changing to orange & green colors; degradation products arising from prolonged or inadequate storage include n-methyl-n'-nitroguanidine, n-nitroguanidine, nitrocyanamide & guanidine; more stable than comparable alkyl-nitrosoureas & alkylnitrosourethanes; at room temp, t/2 at ph 8 is about 200 hr; at ph 7.0 (phosphate buffer) & 37 deg c, t/2 is 170 hr; tap water decomposes mnng much more rapidly than does deionized water
Possibility of hazardous reactions
N-METHYL-N'-NITRO-N-NITROSOGUANIDINE will detonate under high impact. It is sensitive to heat. A sample has exploded when melted in a sealed capillary tube. Incompatible with acids, bases, oxidizing agents and reducing agents. Reacts with bases to release highly toxic, irritating and explosive gases. Reacts slowly with acids to release nitrous acid. Reacts with various nucleophiles, especially amines and thiols. Reacts with aqueous potassium hydroxide to form a highly reactive compound. The crude product from aqueous nitrosation is pyrophoric but recrystallized material is stable (NTP, 1992).

Bioaccumulative potential
An estimated BCF of 0.11 was calculated for N-methyl-N'-nitro-N-nitrosoguanidine(SRC), using an estimated log Kow of -0.92(1,SRC) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF suggests that bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of N-methyl-N'-nitro-N-nitrosoguanidine is estimated as approximately 7.5(SRC), using an estimated log Kow of -0.92(1,SRC) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that N-Methyl-N'-nitro-N-nitrosoguanidine is expected to have very high mobility in soil(SRC).
