<br /> Extinguishing Media Use foam,dry chemical,or carbon dioxide to put out ethyl benzene fires A water sera} 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 vapor,and to protect personnel attempting to stop an ethyl benzene leak Unusual Fire or Explosion Hazards This
<br /> liquid can readily form 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 a self-contained
<br /> breathing apparatus(SOBA)with a full facepiece operated in the pressure-demand or positive-pressure mode
<br /> , SECTIONS REACTIVITY DATA
<br /> Stab ilit)/Po1)merization Eth)1 benzene is stable inclosed containers during routine operations Hazardous polymerization cannot occur
<br /> Chemical Incompatibilities Hazardous chemical reactions can occur between ethyl benzene and strong oxidizing agents, acids, ammonia,
<br /> and bases Conditions to Avoid Avoid any exposure to sources of ignition such as heat,sparks,open flame,and lighted tobacco products,
<br /> etc,and to incompatible chemicals Use caution when entering confined spaces,particularly low-lying areas where explosive concentrations
<br /> 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 /> Carcinogenicity Ethyl benzene is not listed as a carcinogen by the NTP,IARC or OSHA
<br /> Summary of Risks Ethyl benzene N apor is severely irritating to the e)es and to the mucous membranes of the respiratory system Sus-
<br /> tained inhalation of excessive levels can cause depression of the central nervous system(CNS)characterized by dizziness,headache,
<br /> narcosis, and coma SLin contact with liquid ethyl benzene causes trriiation,dermatitis and defatting can also develop The acute oral toxicity
<br /> of ethyl benzene is low,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 of the lung tissue No systemic effects are expected at the levels that
<br /> produce pronounced,unignorable,disagreeable skin and eye irritation The TLVs cited in section 2 are set to prevent this intolerable
<br /> irritation A4edical Conditions AggraN ated b} Long-Term Exposure None reported Target Organs Skin,eyes,respiratory system,and
<br /> CNS Primary Entn Inhalation,skin contact Acute Effects Imtation of the skin,eyes,and respiratory system Also,cardiac-rhythm dis-
<br /> turbance due to sensitization,acute bronchitis,bronchospasm,pulmonary and laryngeal edema,euphoria,headache,giddiness,dizziness,
<br /> and incoordination,as well as possible depression,confusion,and coma Chronic Effects None reported First Aid Eyes Immediately
