<br /> Issued 10181 Revision A, 9191
<br /> Section 1. Material Identification 35
<br />' Automotive Gasoline,Lead-free,Description A mixture of volatile hydrocarbons composed mainly of branched-chain R 1 NFPA
<br /> paraffins,cycloparaffins,olefins,naphthenes,and aromatics In general,gasoline is produced from petroleum,shale oil, 1Z* 3
<br /> Athabasca tar sands,and coal Motor gasolines are made chiefly by cracking processes,wluch convert heavier petrolcum S4 1 4
<br /> fractions into more volatile fractions by thermal or catalytic decomposition Widely used as fuel m internal combustion *Skin _
<br />' engines of the spark-ignited,reciprocating type Automotive gasoline has an octane number of approximately 90 A high absorption
<br /> content of aromatic hydrocarbons and a consequent lugh toxicity are also associated with a lugh octane rating Some HNUS
<br /> gasohnes sold in the US contain a mucor proporuon of tetraethyllead,which is added in concentrations not exceeding 3 ml H 2
<br /> per gallon to prevent engine 'knock"However,methyl-tert-butyl ether(MTBE)has almost completely replaced F 3
<br /> tetraethyllead PPGt
<br /> Other Designations CAS No 8006-61-9,benzin, gasoline, gasolene,motor spirits,natural gasoline,petrol t Sec 8

<br /> Cautions Inhalation of automotive gasoline vapors can cause intense burning in throat and lungs,central nervous system(CNS)
<br /> depression,and possible fatal pulmonary edema Gasoline is a dangerous fire and explosion hazard when exposed to heat and flames

<br /> t See NIOSH RTECS(LX3300004) for addiuonal toxicity data
<br /> Section 3. Physical Data
<br /> Boiling Point Initially, 102 F(39 'C),after 10%distilled, 140'F Densis}/Specific GraN[ty 0 72 to 0 76 at 60'F(15 6 C)
<br /> (60'C), after 509''.distilled,230'F(110'C),after 90%distilled Water Solubillty Insoluble
<br />' 338 -F(170'C),final boiling point,399 F(204 'C)
<br /> Vapor Density(air=1) 3 0 to 4 0
<br /> Appearance and Odor A clear(gasoline may be colored with dye),mobile liquid with a charactenstic odor reeogruzable at about 10 ppm in air
<br /> Section 4 Fare and Explosion Data
<br /> Flash Point -45 F(43 'C) Autoignition Temperature 536 to 853'F(284 to 456 'C} XL 1 3%v/v UEL 6 0%v/v
<br /> Extinguishing Media Use dry chemical carbon dioxide,or alcohol foam as extinguishing media Use of water may be ineffective to extinguish
<br /> fire but use water spray to knock down vapors and to cool fire-exposed drums and tanks to prevent pressure rupture Do not use a solid stream of
<br /> water since it may spread the fuel
<br /> Unusual Fire or Explosion Hazards Automobile gasoline is an OSHA Class IB flammable liquid and a dangerous fire and explosion hazard
<br /> when exposed to heat and flames Vapors can flow to an ignition source and flash back Automobile gasoline can also react violently with
<br /> oxidizing agents
<br /> Special Fire-righting Procedures Isolate hazard area and deny entry Since fire may produce toxic fumes,wear a self-contained breathing
<br /> Apparatus(SCBA)with a full facepiece operated to pressure-demand or positive pressure mode, and full protective clothing When the fire is
<br /> extinguished,use nonsparking tools for cleanup Be aware of runoff from fire control methods Do not release to sewers or waterways
<br />' Section 5 Reactivity Data
<br /> Stnbilit)/Polyrneriratlon Automotive gasoline is stable at room temperature in closed containers under normal storage and handling conditions
<br /> Hazardous polymerization cannot occur
<br /> Chemical Incompatibilities Automotive gasoline can react with oxidizing materials such as peroxides nitric acid and perchlorates
<br />' Conditions to AN old ANoid heat and igruuon sources
<br /> Hazardous products of Decomposition Thermal oxidative decomposition of automotive gasoline can produce oxides of carbon and partially
<br /> oxidized hydrocarbons
