SECTION 4: First aid measures
Description of necessary first-aid measures
Fresh air, rest. Refer for medical attention.
First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Rinse and then wash skin with water and soap.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Do NOT induce vomiting. Give a slurry of activated charcoal in water to drink. Refer immediately for medical attention. See Notes.
Most important symptoms/effects, acute and delayed
Inhalation causes moderate irritation of respiratory tract. Ingestion causes irritation of mouth and stomach. Contact with liquid causes irritation of eyes and mild irritation of skin. (USCG, 1999)
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. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Aliphatic hydrocarbons and related compounds

SECTION 10: Stability and reactivity
Reactivity
May explode on heating rapidly to high temperature. Mixtures with strong inorganic alkalis, acids and combinations of amines and heavy metal oxides are shock-sensitive. Decomposes on burning. This produces toxic fumes of nitrogen oxides. Reacts with bases, combustible substances and oxidants. This generates fire and explosion hazard. Attacks some forms of plastic.
Chemical stability
Stable under recommended storage conditions.
Possibility of hazardous reactions
Sudden absorption of the anhydous liquid or gas on activated carbon or Hopcalite may result in flames.The nitroparaffins, nitromethane, nitropropane, etc. form salts with inorganic bases such as calcium hydroxide. The dry salts are explosive [Chem. Eng. News 30:2344. 1952]. Nitroethane and other nitro compounds are mild oxidizers and should not be heated with easily oxidizable hydrocarbons under confinement [Chem. Eng. News 30:2344. 1940].
Conditions to avoid
no data available
Incompatible materials
Amines; strong acids, alkalis & oxidizers; hydrocarbons; combustibles; metal oxides.

- Toxicity to microorganisms: no data available
Persistence and degradability
14C-labeled nitroethane at 50 ppb was added to a suspension of activated sludge; 23.9% of the initial nitroethane was mineralized in 5 days(1). Aerobic and anaerobic degradation in soil was measured using 14C-labeled nitroethane(1); under aerobic conditions, 11.3% of the initial nitroethane was mineralized to CO2 after 35 days(1); under anaerobic conditions, nitroethane was not mineralized over a 35 day period(1). In the ready biodegradable closed bottle test (OECD Guideline 301D), nitroethane initially present at 2 mg/L was inoculated with sewage effluent(1); less than 1% degradation of nitroethane was measured after 28 days(1). Nitroethane 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(2).
Bioaccumulative potential
A BCF value of 1 was measured for fish (golden orfe (Leuciscus idus)) in a static 3-day test with nitroethane present at 50 ppb(1). According to a classification scheme(2), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of nitroethane can be estimated to be 20(SRC). According to a classification scheme(2), this estimated Koc value suggests that nitroethane is expected to have very high mobility in soil. However, laboratory studies indicate that nitroethane may adsorb to some soil types(SRC). Using a high organic-content peat as a model for soil organic matter, nitroethane had a vapor sorption of nearly 80 mg vapor uptake/g dry peat at a relative pressure of 0.3 at 24 deg C over a 2 to 3 week period; at a relative pressure of 1, a partition capacity of 272 mg/g peat was calculated(3). The nitro group of nitroethane may promote hydrogen bonding to clay and the polarity of the molecule may also allow hydrophilic-coordinative adsorption(4).
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.
