Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. See Notes.

Rinse skin with plenty of water or shower.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Refer for medical attention .

Liquid may dry out skin and cause irritation. (USCG, 1999)

Flush eyes copiously. Wash contaminated areas of body with soap and water.

Fire Fighting Procedures: Explosive decomposition may occur under fire conditions. Fight fires from protected location or maximum possible distance. Use water spray, dry chemical, foam, or carbon dioxide. Use water spray to keep fire-exposed containers cool.

Behavior in Fire: Containers may explode (USCG, 1999)

Use water spray, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.

Evacuate danger area! Consult an expert! Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Remove all ignition sources. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT absorb in saw-dust or other combustible absorbents.

Do NOT absorb in saw-dust or other combustible absorbents.

Remove all ignition sources. establish forced ventilation to keep levels below explosive limit. Absorb liquids in vermiculite, dry sand, earth, peat, carbon, or a similar material and deposit in sealed containers. Follow by washing surfaces well first with alcohol, then with soap and water.

NO open flames, NO sparks and NO smoking. Above 35°C use a closed system, ventilation and explosion-proof electrical equipment. Do NOT expose to friction or shock. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Fireproof. Separated from incompatible materials. See Chemical Dangers. See Notes.Storage Recommendations: Store in a cool, dry, well-ventilated location. Separate from amines, acids, bases, oxidizing materials, and metal oxides. Outside or detached storage is preferred.

TLV: 20 ppm as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans).MAK: skin absorption (H); carcinogen category: 3B

Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.

Wear safety goggles.

Protective gloves.

Use ventilation, local exhaust or breathing protection.

May decompose explosively on shock, friction or concussion. May explode on heating. Decomposes on burning. This produces nitrogen oxides. Reacts with alkalis. Reacts violently with strong oxidants and strong reducing agents. This generates fire and explosion hazard. Mixtures with amines are shock-sensitive.

Stable under recommended storage conditions.

A very dangerous fire hazard when exposed to heat, oxidizers or flame.The vapour is heavier than air and may travel along the ground; distant ignition possible.NITROMETHANE may explode if heated or strongly shocked, especially if mixed with acids, bases [Handling Chemicals Safely 1980. p. 687], acetone, aluminum powder, ammonium salts in the presence of organic solvents, haloforms (chloroform, bromoform), or hydrazine in methanol. Ignites on contact with alkyl aluminum or alkyl zinc halides. Reacts violently with strong bases (potassium hydroxide, calcium hydroxide), amines (1,2-diaminoethane, hydrazine), bromine, carbon disulfide, hydrocarbons, formaldehyde, metal oxides, lithium aluminum hydride, sodium hydride, strong oxidizing agents (lithium perchlorate, nitric acid, calcium hypochlorite). Reacts with aqueous silver nitrate to form explosive silver fulminate [Bretherick, 5th ed., 1995, p. 183]. Mixtures of nitromethane and aluminum chloride may explode when organic matter is present [Chem. Eng. News 26:2257. 1948]. Nitromethane, either alone or in a mixture with methanol and castor oil, has a delayed but violent reaction with powdered calcium hypochlorite [Haz. Home Chem 1963]. Nitromethane reacts violently with hexamethylbenzene [Lewis 2544]. Nitromethane is strongly sensitized by hydrazine [Forshey, D. RR. et al, Explosivestoffe, 1969, 17(6), 125-129].

The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system. This may result in central nervous system depression.

Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the peripheral nervous system, kidneys and liver. This may result in impaired functions.

A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.

AEROBIC: When nitromethane was incubated with activated sludge, 36.2% mineralization occurred in 5 days(1,2). Degradation was low in a closed bottle biodegradability test, using a municipal sewage plant effluent innoculum, with 10% degradation occurring in 28 days(1,2). Aerobic C14 studies performed with soil microorganisms resulted in 5.1% conversion to CO2 in 35 days(1,2); during this time, 22.3% was lost as volatile products(1,2). Nitromethane present at 500 mg/L and inoculated with activated sludge from three municipal treatment plants was toxic to the microorganisms present over the 24 hour study period(3).

A BCF value of 1.4 was measured for fish (Golden ide (Leuciscus idus melanotus)) in a static 3-day test with nitromethane present at 50 ppb(1,2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC). Low bioconcentration was reported for tests using carp (Cyprinus carpio)(4), however actual BCF values were not reported(SRC). The bioconcentration factor in algae (Chorella fusca), as determined in a 24-hr experiment, was 960(1).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of nitromethane can be estimated to be 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that nitromethane is expected to have very high mobility in soil.

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.
