<br /> Section 1. Material Identification 39
<br /> Ethylbeazene(CaH,C2Hs)Descriptlon:Derived by heating benzene and ethylene in presence of aluminum chloride with R I NFPA
<br /> subsequent distillation,by fractionation directly from the mixed xylene stream in petroleum refining,or dehydrogenation 13 3

<br /> Section 4. Fire and Explosion Data
<br /> *
<br /> Flash Point:64'F(19'C)CC Autolgnition Temperature:810'F(432'0) LEL:1.0910 v/v UEL: 6.7%v1v
<br /> Extinguishing Media:Class 1B Flammable liquid.For small rues,use dry chemical,carbon dioxide,or'alcohol-resistant'foam.For large fres,use
<br /> t fog or'aloohol-resistant'foam.Use water only if other agents are unavailable;EB floats on water and may travel to an ignition source and spread
<br /> fere.Unusual Flre or Explosion Hazards:Burning rate=5.8 mm/min.Vapors may travel to an ignition source and flash back.Container may
<br /> explode in heat of fire.EB poses a vapor explosion hazard indoors,outdoors,and in sewers.Special Fire-fighting Procedures:Because fire may
<br /> Produce toxic thermal decomposition products,wear a self-contained breathing apparatus(SOBA)with a full facepiece operated in pressure-demand
<br /> or positive-pressure mode.Cool container sides with water until well after fire is out.Stay away from ends of tanks.For massive fare in cargo area, i
<br /> use monitor nozzles or unmanned hose holders;if impossible,withdraw from area and les fire burn.Withdraw immediately if you hear rising sound
<br /> from venting safety device or notice any tank discoloration due to fire.Do not release runoff from fire control methods to sewers or waterways.
<br /> Section 5. Reactivity Data
<br /> Stablllty/Polymerization:Ethylbenzene is stable at room temperature inclosed containers under normal storage and handling conditions.Hsi-, dots
<br /> Polymerization cannot occur.
<br /> Chemical Incompatibilities:Reacts vigorously with oxidizers.
<br /> Conditions to Avoid:Exposure to heat and oxidizers.
<br /> Hazardous Products of Decomposition:Thermal oxidative decomposition of EB can produce acrid smoke and'irritating fumes.

<br /> Section 6. Health Hazard Data
<br /> Carclnogenlcity:The IARC.06''l WI'P,('69)and OSH06'l do not list Ell as a carcinogen Summary of Risks:Occupational exposure to EB alone
<br /> is rare since it is usually present together with other solvents.EB is irritating to the eyes,skin,and respiratory tract.Vapor inhalation produces
<br /> varying degrees of CNS effects depending on concentration.lite liquid is absorbed through the skin but vapors are not.56 to 64%of inhaled
<br /> ethylbenzene is retained and metabolized.Urinary metabolites following expasure to 23 to 85 ppm for 8 hr are mandeiie acid(6496),phenyl-
<br /> glyoxylic acid(259x),and methylphenylcarbinoill-phenyl ethanol(540).Concurrent exposure to xylene and ethylbenzene causes slower excretion
<br /> of EB metabolites.Based on the rat LDso,one manufacturer gives 3 to 4 oz as the lethal dose for a 100 lb person. Continue on nzv page
