<br /> Extinguishing Media: Use fou n.dry chemical,or carbon dioxide to put out ethyl benzene fires.A water spray may be ineffective in ex-
<br /> tinguishing-the fire,because it can scatter and spread the burning liquid.Use water spray to cool fire-exposed containers of ethyl benzene,to
<br /> disperse ethyl benzene expo:,and to protect personnel attempting to stop an ethyl benzene leak.Unusual Fire or Explosion Hazards: This
<br /> liquid can readily to
<br /> explosive vapor-air mixtures,especially when heated,Ethyl benzene vapor is heavier than air and may travel a con_
<br /> siderable distance to a low-lying source of ignition and flash back to its origin.Special Fire-fighting Procedures: Wear s self�ontaincd
<br /> breathing apparatus(SCBA)with a full facepiece operated in the pressure-demand or positive-pressure mode.
<br /> SECTION REACTIVITY DATA
<br /> ChemSt2bilical lncompizatiaa: Ethyl bcazenz is stable in closed containers during routine operations.Hazardous Polymerization tannat occur.
<br /> Chemical Incompatibilities: Hazardous chemical reactions can occur between ethyl benzene and strong oxidizing agents,acids,Iammoni
<br /> and bases.Conditions to Avoid: Avoid anv exposure to sources of ignition such as head sparks,apcn flame,and lighted
<br /> to produce,
<br /> etc.,and m incompatible chemicals. Use caution when entering:'tonfiaed spaces,pa'ticulazly low-lying areas where explosive coo Products,'Of ethyl benzene vapor may be present Provide good ventilation to such areas to prevent the concentration of this vapor.Hazardous Prod-
<br /> ucts of Decomposition:Thermal-oxidative degradation can include toxic gases such as carbon monoxide and/or aromatic hydrocarbon gases.
<br /> SECTION 6. HEALTH HAZARD INFORMATION
<br /> Carrinogenicit�: Eth}9 benzene is
<br /> Summary not listed as a carcinogen by the N7P,IARC,or OSHA.
<br /> y of Risks: Ethyl benzene vapor is severely irritating to the eyes and to the mucous membranes of the respiratory system.Sus-
<br /> tained inhalation of excessive levels eao cause depression of the central nervous system(CNS)characterized by dizziness,headache,
<br /> narcosis,and cOrna.Skin contact with liquid ethyl benzene causes irrkEdor.;dermatitis and defatting tau also develop.The acute oral toxicity
<br /> of ethyl benzene is lou;however,ingestion of it presents a serious aspiration hazard.Aspirating even a small amount into the lungs can
<br /> result in extensive edema(lungs filled with fluid)and hemorrhaging cf the lung tissue.No systemic effects arc expected at the levels that '
<br /> produce pronounced,;�-ignorabJe,disagreeable skin and eve irritation.The TI-Vs cited in section 2 are set to prevent this intolerable
<br /> irritation.Medical Conditions Aggravated by Long-Term Exposure: None reported.Target Organs: Skin,eyes,respiratory system and
<br /> CNS.Primary Entr}•: Inhalation,skin contact Acute Effects: :Irritation of the skin;eyes,and respiratory system Also,eardiacrrh
<br /> turbance due to sensitization;acute bronchitis,bronchospasm,pulmon }'u+m dis-
<br /> and incoordination,as well as possible dcpressior.;confusion;and com Chrrnic Effects:eNo; a phoria;headache;giddiness;dizziness;
