<br /> Flash Point 64'F(18'C)CC I Autoignition Temperature:810'F(432'C) LEL l 096 v/v UEL 6 7%v/v
<br /> Extinguishing Media Class IB Flammable liquid For small fires,use dry chemical,carbon dioxide,or'alcohol-resistant'foam For large fires,use
<br /> I fog or'alcohol-resistant'foam Use water only if other agents are unavailable,EH floats on water and may travel to an ignition source and spread
<br /> fire Unusual Fire 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 thein a]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 fire in cargo area,
<br /> use monitor nozzles w unmanned hose holders,if impossible,withdraw from area and let fire burn Withdraw unmediately 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/PoIymerizatlon Ethylbenzene is stable at room temperature m closed containers under normal storage and hardiing conditions Hazardou
<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 /> Carcinogenicity The IARC.06A)NTP,(r69)and OSHA"')do not list EB as a carcinogen.Summary of Risks Occupational exposure to£B 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 /> i varying degrees of CNS effects depending on concentration The ligwd is absorbed through the skin but vapors are not.56 to 6490 of inhaled
<br /> ethylberizene is retained and metabolized Urinary metabolites following exposure to 23 to 85 ppm for 8 hr are mandelic acid(649,6),phenyl-
<br /> glyoxylic acid(2590),and methylphenylcarbmol/1-phenyl ethanol(5%) 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 CO,ilviirc an ren page
