e <br /> i Petroleum distillate fuels exhibit relatively low acute <br /> inhalation and dermal -`7:�xicity, Concentrations of 160 to 270 ppm <br /> gasoline vapor hav^ been reported to cause eye, nose, and throat <br /> irritation in people after several hours of exposure. Levels of <br /> 500 to 900 ppm have been reported to cause irritation and dizziness <br /> in one hour and 2,000 ppm has been reported to cause mild <br /> I 0i anesthesia in 30 minutes. Gasoline, kerosene, and some jet fuels <br /> 3" will cause severe eye irritation on contact with the eye and low to <br /> moderate skin irritation on contact with the skin. <br /> Ingestion cf 10 to 15 grams (2 to 3 teaspoons) of <br /> gasoline has caused death in children. In adults, ingestion of 20 <br /> to 50 grams may produce severe symptoms of poisoning. Secondary <br /> pneumonia may occur if gasoline or other fuels are aspirated into ' <br /> the lungs. <br /> .w <br /> Some gasoline additives, such as ethylene .dichloride, , <br /> ethylenc dibromide, and tetraethyl- and tetramethyl-lead are highly <br /> toxic materials; however, their concentrations in gasoline are so <br /> low that their contribution to the overall toxicity of gasoline is <br /> i ' negligible in most instances. <br /> f " Petroleum distillate fuels are flammable. Under certain <br /> h: conditions, this property presents a greater risk than . ,oxicity, <br /> Five of the 13 substances covered by this procedure are classified r <br /> w by the Federal Department of Transportation as flammable liquids as <br /> ; a all five have flash points of 100 degrees F or less. These fuels <br /> are gasoline, gasohol, .TP-.1, JP-4, and No. 1 fuel oil.
