Health Hazard
Irritating to the eyes, nose, throat, upper respiratory tract, and skin. Inhalation may be fatal as a result of spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis, and pulmonary edema. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. (USCG, 1999)
Reactivity Profile
2,2-DIMETHYL OCTANOIC ACID reacts exothermically with bases. May corrode or dissolve iron, steel, and aluminum parts and containers. May react with active metals to form gaseous hydrogen and a metal salt. Reacts with cyanide salts to generate gaseous hydrogen cyanide. Reacts with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides to generate flammable and/or toxic gases and heat. Reacts with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Reacts with carbonates and bicarbonates to generate a harmless gas (carbon dioxide) but some heat. Exothermically oxidized by strong oxidizing agents and reduced by strong reducing agents to give a range of products. May initiate polymerization reactions or catalyze other chemical reactions.
