Move 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/effects, acute and delayed
ACUTE/CHRONIC HAZARDS: Flammable. (NTP, 1992)
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
Flammable. Insoluble in water.
Chemical stability
Stable under recommended storage conditions.
Possibility of hazardous reactions
Saturated aliphatic hydrocarbons, such as N-HEXADECANE, 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.
Conditions to avoid
no data available
Incompatible materials
Incompatible materials: Strong oxidizing agents.
Hazardous decomposition products
When heated to decomposition it emits acrid smoke and irritating vapors.

Persistence and degradability
Degradation in seawater by oil oxidizing microorganisms: 59.2% breakdown after 21 days at 22 deg C in stoppered bottles containing 1000 ppm mixtues of alkanes, cycloalkanes and aromatics.
Bioaccumulative potential
An estimated BCF of 870 was calculated in fish for hexadecane(SRC), using a estimated log Kow of 8.20(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is high, provided the compound is not metabolized by the organism(SRC). A BCF range of 5.0-47.9 was derived using carp (Cyprinus carpio) which were exposed over an 8-week period to levels of 0.2 and 2.0 ppm hexadecane(3). However, the derived BCF in carp failed to correct for the actual solubility of n-hexadecane(4) which would yield a much higher BCF(SRC). In an 8-hr exposure study, the BCF for hexadecane in mussels (Mytilus edulis) was reported to be less than 1(5), but again the reported BCF was not corrected for the actual solubility of hexadecane(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of hexadecane can be estimated to be 53,000(SRC). According to a classification scheme(2), this estimated Koc value suggests that hexadecane is expected to be immobile in soil(SRC). From the experimental value of Freundlich adsorption constants and organic carbon contents in three Canadian soils (Wendover 16.2% OC; Vaudreil 10.0% OC; Grimsby 1.0% OC)(3), Koc values can be estimated to be in the range of approximately 50-400(SRC). The experimental data of other investigators suggest that less than 20% of hexadecane from solution is adsorbed in soil, sludge and sediment(4-6). However, in all the adsorption experiments(3-6), the concentration of hexadecane solution used for the adsorption study far exceeded the aqueous solubility of hexadecane making the results questionable(SRC).
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.
