    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

    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)

    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.Stability and reactivity

    10.1 Reactivity

    no data available

    10.2 Chemical stability

    Stable under recommended storage conditions.

    10.3 Possibility of hazardous reactions

    Saturated aliphatic hydrocarbons, such as N-OCTADECANE, 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

    no data available

    10.5 Incompatible materials

    Incompatible materials: Strong oxidizing agents.

    10.6 Hazardous decomposition products

    Hazardous decomposition products formed under fire conditions. Carbon oxides.

    • Toxicity to algae: no data available
    • Toxicity to microorganisms: no data available

    12.2 Persistence and degradability

    AEROBIC: Biodegradation of octadecane will occur under certain environmental conditions. Using a sediment sample and marine-water taken from Colgate Creek, Maryland (a relatively oil polluted environment), 30% octadecane was utilized by bacteria after 28 days; using a sediment sample and marine-water taken from Eastern Bay, Maryland (a relatively oil free environment), 6% octadecane was utilized by bacteria after 28 days; using the sediment sample from Colgate Creek in water taken from Eastern Bay, 24% octadecane was utilized by bacteria after 28 days; using a sediment sample from Eastern Bay and water from Colgate Creek, 15% octadecane was utilized by bacteria after 28 days(1). Octadecane, present as a component of Biodiesel, has a calculated half-life of 2.5 days, from examination of the primary aerobic biodegradation of commercial biodiesel fuel at 100 ppm, using unacclimated pond-water(2).

    12.3 Bioaccumulative potential

    An estimated BCF of 730 was calculated in fish for octadecane(SRC), using a log Kow of 8.36(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC).

    12.4 Mobility in soil

    The Koc of octadecane is 2.2X10+7(1). According to a classification scheme(2), this Koc value suggests that octadecane is expected to be immobile in soil.

    12.5 Other adverse effects

    no data available

    13.Disposal considerations

    13.1 Disposal methods

    Product

    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.
