    4.1 Description of necessary first-aid measures

    General advice

    Consult a physician. Show this safety data sheet to the doctor in attendance.

    If inhaled

    If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.

    In case of skin contact

    Wash off with soap and plenty of water. Consult a physician.

    In case of eye contact

    Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.

    If swallowed

    Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.

    4.2 Most important symptoms/effects, acute and delayed

    SYMPTOMS: Symptoms associated with exposure to aliphatic hydrocarbons may include nausea vomiting, dizziness, weakness, central nervous system effects such as depression, convulsions and, in extreme cases, coma. Other symptoms may include pulmonary and gastrointestinal irritation, pulmonary edema, bronchial pneumonia, anorexia, anemia, nervousness, pain in the limbs and numbness. ACUTE/CHRONIC HAZARDS: Inhalation of this chemical may cause pulmonary irritation. It may also cause IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.

    4.3 Indication of immediate medical attention and special treatment needed, if necessary

    /SRP:/ 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 if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the 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/

    10.1 Reactivity

    no data available

    10.2 Chemical stability

    Stable under recommended storage conditions.

    10.3 Possibility of hazardous reactions

    Combustible.Saturated aliphatic hydrocarbons, such as N-DODECANE, may be incompatible with strong oxidizing agents like nitric acid. Charring of the hydrocarbon may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings, aliphatic saturated hydrocarbons are mostly unreactive. They are not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents. When heated sufficiently or when ignited in the presence of air, oxygen or strong oxidizing agents, they burn exothermically to produce carbon dioxide and water.

    10.4 Conditions to avoid

    12.Ecological information

    12.1 Toxicity

    • Toxicity to fish: no data available
    • Toxicity to daphnia and other aquatic invertebrates: no data available
    • Toxicity to algae: no data available
    • Toxicity to microorganisms: no data available

    12.2 Persistence and degradability

    AEROBIC: Dodecane has been determined to be readily biodegradable based results of analogous chemicals incubated using an activated sludge inoculum in the Japanese MITI test(1). Thirty seven percent dodecane was mineralized in a 5-day biodegradability test using activated sludge with most of the remaining radioactivity from the labeled substrate being bound to the sludge as un-extractable residue(2). In other studies, 74% of the theoretical BOD was achieved in 24 hrs(3).

    12.3 Bioaccumulative potential

    A log BCF of 1.72 (BCF = 53) for golden orfes and a BCF of 50 for golden ide fish (Leuciscus idus melanotus) was determined for n-dodecane after 3 days exposure(1,2). An estimated BCF upper limit of <240 L/kg was calculated for dodecane in fathead minnows in water at concentrations less than its maximum aqueous solubility(3). According to a classification scheme(4), these BCF values suggest that bioconcentration in aquatic organisms is moderate to high(SRC). The bioaccumulation factor of n-dodecane in algae (Chlorella fusca) was determined to be 6,250 after 1 day(1); a log BCF of 3.80 for green algae after 24 hours exposure was also determined(1). Only traces of n-dodecane were taken up by a marine diatom from crude oil(5). The bioaccumulation factor of n-dodecane in activated sludge was determined to be 1,300 after 5 days(6).

    12.4 Mobility in soil

    Using a structure estimation method based on molecular connectivity indices(1), the Koc of dodecane can be estimated to be 4800(SRC). According to a classification scheme(2), this estimated Koc value suggests that dodecane is expected to have slight mobility in soil. In a study conducted to mimic a spill of 1.27 L/sq m, dodecane (present in JP-4 jet fuel) was transported to a depth of 10 cm; at the end of the study (134 days), it was no longer detected(3). In another study, it was determined that dodecane is slowly intercalated into well dried montmorillonite clay(4).

    12.5 Other adverse effects

    no data available

    13.Disposal considerations

    13.1 Disposal methods
