HESS <br /> MATERIAL SAFETY'DATA SHEET <br /> .Gasoline,All Grades tNSDs No.9950 <br /> DO NOT INDUCE VOMITING. Do not give liquids. Obtain Immediate medical attention.If spontaneous <br /> vomiting occurs,lean victim forward to reduce the risk of aspiration. Small amounts of matedal which <br /> enter the mouth should be rinsed out until the taste Is dissipated. <br /> INHALATION <br /> Remove person to fresh air. If person is not breathing,ensure an open airway and provide artificial <br /> respiration. If necessary,provide additional oxygen once breathing is restored if trained to do so.Seek <br /> medical attention Immediately. <br /> 5. FIRE FIGHTING MEASURES <br /> FLAMMABLE PROP RTIES: <br /> FLASH POINT: 45°F (-VC) <br /> AUTOIGNITION TEMPERATURE: highly vadable;>530°F (>280'C) <br /> OSHA/NFPA FLAMMABILITY CLASS: 1A(flammable liquid) <br /> LOWER EXPLOSIVE LIMIT(°/,): 1.4% <br /> UPPER EXPLOSIVE LIMIT(%): 7.6% <br /> FIRE AND EXPLOSION HAZARDS <br /> Vapors maybe Ignited rapidly when exposed to heat,spark,open flame or other source of Ignition. <br /> Flowing product may be Ignited by self-generated static electricity. When mixed with air and exposed to <br /> an Ignition source,flammable vapors can burn in the open or explode In confined spaces.Being heavier <br /> than air,vapors may travel long distances to an Ignition source and flash back. Runoff to sewer may <br /> cause fire or explosion hazard. <br /> EXTINGUISHING MEDIA <br /> SMALL FIRES: Any extinguisher suitable for Class B fires,dry chemical,CO2,water spray,fire fighting <br /> foam,or Halon. <br /> LARGE FIRES: Water spray,fog or fire fighting foam. Water may be Ineffective for fighting the fire,but <br /> may be used to cool fire-exposed containers. <br /> During certain times of the year and/or In certain geographical locations,gasoline may contain MTBE <br /> and/or TAME. Firefighting foam suitable for polar solvents Is recommended for fuel with greater than <br /> 10%oxygenate kwncentrallon-refer to NFPA 11 "Low Expansion Foam-1994 Edition." <br /> FIRE FIGHTING INSTRUCTIONS <br /> Small fires In the Incipient(beginning)stage may typically be extinguished using handheld portable fire <br /> extinguishers and other fire fighting equipment <br /> Firefighting activities that may result in potential exposure to high heat,smoke or toxic by-products of <br /> combustion should require NIOSH/MSHA-approved pressure-demand self-contained breathing <br /> apparatus with full faceplece and full protective clothing. <br /> Isolate area around container Involved In fire. Cool tanks, shells,and containers exposed to fire and <br /> excessive heal with water. For massive fires the use of unmanned hose holders or monitor nozzles may <br /> be advantageous to further minimize personnel exposure Major fires may require withdrawal,allowing <br /> the tank to bum. Large storage tank fires typically require specially trained personnel and equipment to <br /> extinguish the fire,often Including the need for properly applied fire fighting foam. <br /> See Section 16 for the NFPA 704 Hazard Rating. <br /> Revision Date: 09/25/2007 Page 3 of 9 <br />
