No 385 Elhylbenzene 9192
<br /> Section 6. Health Hazard Data
<br /> Medical Conditions Aggravated by Long-Term Exposure:Skin and CNS diseases and unpaved pulmonary function(especially obstructive--
<br /> airway disease) Target Organs.Eyes,respiratory system,skin,CNS,blood Primary Entry Routes:Inhalation,skin and eye contact.Acute
<br /> WEsVapor inhalation of 200 ppm caused transient eye irritation, 1000 ppm caused eye irritation with profuse watering(tolerance developed
<br /> y),2000 ppm caused severe and unmediate eye untation and watering,nasal nmtation,chest constriction.and vertigo,5000 ppm was
<br /> able and caused eye and nose irritation Inhalation of high concentrations may cause narcosis,cramps,and death due to respiratoryparalysis
<br /> Skin exposed to pure ethylbenzene for 10 to 15 nun absorbed 22 to 33 mg/cm2/hr Immersion of hand in solutions of 112&156 mg/L for 1 hr
<br /> absorbed 118&215 7 gg/crnz/hr,respectively Chronic Effects Repeated skin contact may cause dryness,scaling,and fissuring Workers
<br /> chronically exposed to>100 ppm complained of fatigue,sleepiness,headache,and mild irritation of the eyes and respiratory tract.Repeated vapor
<br /> Lnhalauon may result in blood disorders,particularly leukopema(abnormally low level of white blood cells)and lymphocytosis
<br /> FIRST AID
<br /> Eyes.Do not allow victim to rub or keep eyes tightly shut.Gently lift eyelids and flush immediately and continuously with flooding amounts of
<br /> water until transported to an emergency medical facility Consult a physician immediately Skin:Quickly remove contaminated clothing Rinse
<br /> with flooding amounts of water for at least 15 min Wash exposed area with soap and water For reddened or blistered skin,consult a physician.
<br /> Inhalation:Remove exposed person to fresh air and support breathing as needed Ingestion:Never give anything by mouth to an unconscious or
<br /> convulsing person Contact a poison control center and unless otherwise advised,have that conscious and alert person drink 1 to 2 glasses of water
<br /> to dilute Do not induce vomitingl Aspiration of even a small amount of EB in vomitus can cause severe damage since its low viscosity and surface
<br /> tension will cause it to spread over a large area of the lung tissue
<br /> Arter first aid,get appropriate in-plant,paramedic,or community medical support.
<br /> Note to Physicians:BEI=mandelic acid to untie(1 5 g/g of creatinine),sample at end of shift at workweeks end.Since this test is not specific,
<br /> test for EB in expired air for confirmation.
<br /> Section 7. Spill, Leak,and Disposal Procedures
<br /> Splu/Leak:Notify safety personnel Isolate and ventilate area,deny entry and stay upwind Shut off all ignition sources Cleanup personnel should
<br /> protect against vapor inhalation and skin/eye contact.Take up small spills with earth,sand vermiculite,or other absorbent.noncombustible mate-
<br /> nal and place in suitable container Dike far ahead of large spill for later reclamation or disposal Report any release>1000 lb Follow applicable
<br /> OSHA regulations(29 CFR 1910 I20) Environmental Transport:If released to soil,EB partially evaporates into the atmosphere,with a half-life
<br /> of his to wks,and some leaches into groundwater,especially in soil with low organic carbon content Biodegradation occurs with a half-life of 2
<br /> days Some EB may absorb to sediment or bioconcentrate in fish Evidence points to slow biodegradation in groundwater In au,it reacts with
<br /> photochemically produced hydroxyl radicals with a half-life of hrs to 2 days Additional amounts may be removed by rain Eeotoxkcity Values:
<br /> Shrimp(Mystdopsu Bahia),LC50=87 6 mg/U96 hr,sheepshead minnow(Cyprinodon varwgalus)LCso=275 mg/496 hr;fathead minnow
<br /> (Pimephales prontelas)LC5o=423 mg/L,196 hr in hard water&48.5 mgA496 hr in softwater Disposal.A candidate for rotary lobi incineration at
<br /> 1508 to 2912'F(820 to 1600-C),liquid injection incineration at 1202 to 2912'F(650 to 1600'C),and fluidized bed incineration at 842 to 1796'F
<br /> (450 to 980'Q Contact your suppher or a licensed contractor for detailed recommendations.Follow applicable Federal,state,and local regulations

<br /> Section 8. Special Protection Data
<br /> Goggles Wear protective eyeglasses or chemical safety goggles,per OSHA eye-and face-protection regulations(29 CFR 1910 133) Because
<br /> contact lens use in industry is controversial,establish your own policy Respirator.Seek professional advice prior to selection and use.Follow
<br /> OSHA respirator regulations(29 CFR 1910 134)and,if necessary,wear a MSHA/NIOSH-approved respirator For<1000 ppm,use a powered
<br /> air-punfymg respirator with an appropriate organic vapor cartridge,a supphed-air respirator(SAR),SCBA,or chemical cartridge respirator with
<br /> appropriate organic vapor cartridge For<2000 ppm,use a SAR or SOBA with a full faceptece.For emergency or nonroutine operations(cleaning
<br /> spills,reactor vessels,or storage tanks),wear an SCBA Warntngi Air purifying respirators do not protect workers in oxygen-deficient atmo-
<br /> spheres If respirators are used,OSHA requires a respiratory protection program that includes at least medical certification.training,fit testing,
<br /> periodic environmental monitoring.maintenance.inspection,cleaning,and convenient,sanitary storage area Other:Wear chemically protective
<br /> gloves,boots.aprons,and gauntlets made of Viton or polyvinylchloride to prevent skin contact Ventilation:Provide general and local exhaust
<br /> ventilation systems to maintain airborne concentrations below the OSHA PELs(Sec.2) Local exhaust ventilation is preferred because it prevents
<br /> I contaminant dispersion into the work area by controlling it at its source.0'31 Safety Stations:Make available in the work area emergency
<br /> eyewash stations,safety/quick-drench showers,and washing famhues Contaminated Equipment:-Separate eontammated work clothes from
<br /> street clothes and launder before reuse.Remove this material from your shoes and clean PPE Comments:Never eat,dritik,or smoke in work
<br /> areas Practice good personal hygiene after using this maternal,especially before eating.drinking,smoking,using the toilet.or applying cosmetics
<br /> Section 9. Special Precautions and Comments
<br /> Storage Requlremeots:Store in a cool,dry,well-ventilated area away from ignition sources and oxidizers Outside or detatehed storage is
<br /> preferred If inside,store in a standard flammable liquids cabinet Containers should have flame-arrester or pressure-vacuum venting To prevent
<br /> static sparks.`electncally ground and bond all equipment used with ethylbenzene.Install Class 1,Group D electrical equipment Engineering, i
<br /> Controls:To reduce potential health hazards,use sufficient dilution or local exhaust ventilation to control airborne contaminants and to maintain
<br /> levels as low as possible Purge and ventilate reaction vessels before workers are allowed to enter for rriarntenarnce or cleanup Administrative
<br /> Controls:'Consider preplacement and periodic medical exams of exposed workers that emphasize the CNS,skin.blood,and respiratory system.I'
