Fire Fighting
Fire Extinguishing Agents Not to Be Used: Water or foam may cause frothing.;Fire Extinguishing Agents: Dry chemical, carbon dioxide (USCG, 1999)
Use water spray, powder, foam, carbon dioxide.
First Aid Measures
Fresh air, rest.
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.
First Aid
EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.;SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.;INHALATION: 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.;INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)
Fire Fighting Procedures
Use water spray, dry chemical, foam or carbon dioxide. Water or foam may cause frothing. Water spray may be used to flush spills away from exposures.
Water or foam may cause frothing.
Nonfire Spill Response
SMALL SPILLS AND LEAKAGE: If you spill this chemical, use absorbent paper to pick up all liquid spill material. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with alcohol followed by washing with a strong soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.;STORAGE PRECAUTIONS: You should protect this chemical from exposure to light. Keep the container tightly closed under an inert atmosphere, and store under refrigerated temperatures. (NTP, 1992)
Disposal Methods
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
Charge directly or after dissolving in a flammable solvent into the furnace with afterburner.
Preventive Measures
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.

Environmental Fate
TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 340,000 for the free acid(SRC), determined from a log Kow of 7.64(2) and a regression-derived equation(3), indicates that undissociated oleic acid is expected to be immobile in soil(SRC). The pKa of oleic acid is 5.02(4), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). Volatilization of oleic acid from moist soil is not expected to be an important fate process because the acid is in the anion form and anions do not volatilize(SRC). Oleic acid is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 5.46X10-7 mm Hg(6). Biodegradation is expected to be an important fate process in soil based on half-lives of 0.2 and 0.66 days in screening tests(7,8).
AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 340,000 for the free acid(SRC), determined from a log Kow of 7.64(2) and a regression-derived equation(3), indicates that undissociated oleic acid is expected to adsorb to suspended solids and sediment(SRC). A pKa of 5.02(4) indicates oleic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(5). According to a classification scheme(6), an estimated BCF of 10(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). A 47 and 52 theoretical %BOD for oleic acid measured over a period of 5 days using sewage inoculum(8) and a biodegradation half-life of 0.66 days using activated sludge inocula(9) suggest that biodegradation may be an important environmental fate process in aquatic ecosystems(SRC).
ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), oleic acid, which has a vapor pressure of 5.46X10-7 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase oleic acid is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for cis-oleic acid and trans-oleic acid reactions in air are estimated to be 5.1 and 4.6 hours(SRC), calculated from rate constants of 7.6X10-11 and 8.3X10-11cu cm/molecule-sec at 25 °C(SRC) that were derived using a structure estimation method(3). Vapor-phase oleic acid is also degraded in the atmosphere by reaction with ozone(SRC); the half-life for cis-oleic acid and trans-oleic acid reactions in air are estimated to be 2.1 and 1.4 hours(SRC), respectively, calculated from rate constants of 1.3X10-16 and 2.0X10-16 cu cm/molecule-sec at 25 °C(SRC) that were derived using a structure estimation method(3). Particulate-phase oleic acid may be removed from the air by wet or dry deposition(SRC). Oleic acid does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight(4).
Food Survey Values

Ecotoxicity Excerpts
/AQUATIC SPECIES/ The toxicities of chemicals found in bleached kraft pulp mill effluent were assessed using a sea urchin sperm toxicity test. Sperm of the purple sea urchin, Strongylocentrotus purpuratus, were preincubated with 12 individual compounds, including resin acids, unsaturated fatty acids, their chlorinated derivatives and chlorinated guaiacols. Sperm were then coincubated with eggs and inhibition of fertilization and the effects on sperm motility were assessed. Resin acids, which are highly toxic to juvenile salmonids in freshwater, were less toxic in seawater (EC50s ranging from 2 to more than 20 mg/L). Unsaturated linoleic and linolenic fatty acids inhibited fertilization at lower concentrations (EC50s of 0.28 to 1.07 mg/L) than resin acids, although they are less toxic than resin acids to freshwater fishes. Oleic acid was not significantly toxic up to 75 mg/L. Chlorinated derivatives showed increasing toxicity with increasing chlorination, and chlorinated resin acids were more toxic than their unchlorinated parent compound. Dichlorostearic acid was the most toxic compound tested, with an EC50 of 0.057 mg/L. All compounds except fatty acids inhibited sperm motility. These results indicate that some of the major constituents of pulp mill effluent exhibit very different levels of toxicity in seawater using a sea urchin sperm cell toxicity test as compared to freshwater bioassays using juvenile salmonids. In addition, mechanisms of action on the sperm appear to differ among the compounds. Accurate quantification of the compounds in effluent as well as the potential effect of the effluent on other marine organisms remains to be determined.

Mechanism of Action
Insulin resistance is linked with a cluster of multiple risk factors and excessive acceleration of atherosclerosis. The underlying mechanism is not, however, fully understood. To determine the link between insulin resistance and altered vascular function, we focused on the effect of various non-esterified fatty acids on diacylglycerol-protein kinase C pathway and mitogen-activated protein kinase activity in cultured aortic smooth muscle cells. Incubation of the cells with saturated non-esterified fatty acids (200 micromol/L) for 24 hr, such as palmitate or stearate, induced a significant increase in diacylglycerol concentrations by about fivefold or eightfold, respectively, whereas oleate induced a slight increase in diacylglycerol concentrations by 1.8-fold and arachidonate induced none. In addition, the increased diacylglycerol concentrations induced by palmitate were completely restored to control concentrations by triacsin C, acyl-CoA synthetase inhibitor. These results suggest that saturated non-esterified fatty acids may increase diacylglycerol concentrations through de novo pathway by stepwise acylation. In parallel with the increased diacylglycerol, incubation of the cells with saturated non-esterified fatty acids significantly induced the activation of protein kinase C and mitogen-activated protein kinase. The palmitate-induced increase in mitogen-activated protein kinase activity was restored to control concentrations by GF109203X (5 x 10(-7) mol/L), a specific protein kinase C inhibitor, suggesting a protein kinase C-dependent activation of mitogen-activated protein kinase. Saturated non-esterified fatty acids induced an increase in de novo diacylglycerol synthesis and subsequent activation of protein kinase C and mitogen-activated protein kinase in cultured aortic smooth muscle cells. This could contribute to the altered vascular functions in the insulin resistant state.
Biological Half-Life
No pharmacokinetic data available.
METABOLISM OF TRITIATED OLEIC ACID WAS STUDIED IN RATS DURING 600 DAYS. /ELIMINATION OCCURED/ SLOWLY WITH T/2 OF ABOUT 200 DAYS.
Metabolism/Metabolites
Like most fatty acids, oleic acid may undergo oxidation via beta-oxidation and tricarboxylic acid cycle pathways of catabolism, where an additional isomerization reaction is required for the complete catabolism of oleic acid. Via a series of elongation and desaturation steps, oleic acid may be converted into longer chain eicosatrienoic and nervonic acid.
Proposed mechanisms for fatty acid uptake by different tissues range from passive diffusion to facilitated diffusion or a combination of both. Fatty acids taken up by the tissues can either be stored in the form of triglycerides (98% of which occurs in adipose tissue depots) or they can be oxidized for energy via the beta-oxidation and tricarboxylic acid cycle pathways of catabolism.
The beta-oxidation of fatty acids occurs in most vertebrate tissues (except the brain) using an enzyme complex for the series of oxidation and hydration reactions resulting in the cleavage of acetate groups as acetyl-CoA (coenzyme A). An additional isomerization reaction is required for the complete catabolism of Oleic Acid. Alternate oxidation pathways can be found in the liver (omega-oxidation) and in the brain (alpha-oxidation).
Fatty acid biosynthesis from acetyl-CoA takes place primarily in the liver, adipose tissue, and mammary glands of higher animals. Successive reduction and dehydration reactions yield saturated fatty acids up to a 16-carbon chain length. Stearic Acid is synthesized by the condensation of palmitoyl-CoA and acetyl-CoA in the mitochondria, and Oleic Acid is formed via a mono-oxygenase system in the endoplasmic reticulum.
The normal metabolic pathway of palmitic and stearic acids in mammals produces oleic acid. Oleic acid, on a series of elongation and desaturation steps, may be converted into longer chain eicosatrienoic and nervonic acid.
Weanling rats were fed diets containing rapeseed, canbra or ground nut oils for 8 or 60 days. They received simultaneously (14)C erucate and (3)H2 oleate by iv application. Animals were killed 2 or 19 hr after injection, lungs were removed and the distribution of (14)C and (3)H radioactivities was determined in pulmonary lipid fractions and in fatty acids of phospholipids and neutral lipids. More (14)C than (3)H radioactivity was recovered in lung lipids 3 and 19 hr after admin of labelled fatty acids. (14)C and (3)H radioactivity in the phospholipid fraction was larger than in the triglyceride fraction, the inverse was observed after 19 hr. The main part of (14)C radioactivity was present in the monounsaturated fatty acids, in decr order: 18:1, 24:1, 16:1 and 20:1. Erucic acid was slightly esterified in phospholipids.
Absorption, Distribution and Excretion
Fatty acid uptake by different tissues may be mediated via passive diffusion to facilitated diffusion or a combination of both. Fatty acids taken up by tissues are then stored in the form of triglycerides or oxidized. Oleic acid was shown to penetrate rat skin. Following oral administration of Brucea javanica oil emulsion in rats, the time of oleic acid to reach peak plasma concentration was approximately 15.6 hours.
Following oral administration of trace amounts of oleic acid, less than 10% of total oleic acid was found to be eliminated via fecal excretion.
Radio-labelled oleic acid was detected in the heart, liver, lung, spleen, kidney, muscle, intestine, adrenal, blood, and lymph, and adipose, mucosal, and dental tissues. Oleic acid is primarily transported via the lymphatic system.
No pharmacokinetic data available.
Radioactivity has been traced to the heart, liver, lung, spleen, kidney, muscle, intestine, adrenal, blood, and lymph, and adipose, mucosal, and dental tissues after administration of radioactive oleic, palmitic, and stearic acids.
Simultaneous ingestion of trace amounts of 14C-triolein (10 uCi) and 3H-oleic acid (20 uCi) in 42 g of carrier fat by patients with normal fecal fat excretion resulted in estimated fecal excretion of less than 10% of both substances. Gastrointestinal transit times for 14C-triolein, 3H-oleic acid, and a nonabsorbable marker, CrCl3, did not differ significantly.
