It is a colorless to red liquid with <br /> a petroleum odor. It is a flammable liquid with a high volatility and its vapors are heavier <br /> than air. <br /> Under uu-:tions where exposure may occur, mild eye, nose and throat irritation, <br /> 1 headaches,nausea,drowsiness.and dizziness may possibly occur. In open areas,ventilation <br /> is usually adequate to prevent prolonged br:.athing of high gasoline vapor concentrations. <br /> Gasoline containing Benzene,Tolt.;ne,Ethyl Benzene and Xylene which may be potentially <br /> �-•` carcinogenic. A hazard assessment of these compounds follows below and is outside the <br /> scope of the gasoline assessment. <br /> Gasoline has a flash point of 45°C. 'I1te flammability limits are subject to blending but <br /> are listed at 1.4 to 7.6 To by volume in air. Extreme caution must be taken to keep sources <br /> of ignition from coming into contact with gasoline vapors. A.25 foot NO SMO1QNQ zone <br /> must be)rain <br /> if F <br />
