OR NO. 385 Ethylknzene 9x92
<br /> i Seztion'6. Health Hazard Data l�
<br /> Medical Conditions Aggravated by Long-Term Exposure.Skin and CNS diseases and impaired pulmo, function(cspccially obstructive
<br /> airway disease).Target Organs:Eyes,respiratory system,skin,CNS,blood.Primary Entry Routes:Inhalation,skin and eye contact.Acute
<br /> EfTects: Vapor inhalation of 200 ppm caused transient eye irritation; 1000 ppm caused eye irritation with profuse watering(tolerance developed
<br /> -•oidly).2000 ppm caused severe and immediate eye irritation and watering,nasal irritation,chest constriction,and vertigo;5000 ppm was
<br /> olcrable and caused eye and nose irritation.Inhalation of high concentrations may cause narcosis,cramps,and death due to respiratory paralysis.
<br /> Kin exposed to pure ethylbenzene for 10 to 15 min absorbed 22 to 33 rhg/cm2/hr.Immersion of hand in solutions of 112&156 mg/L for 1 by
<br /> bsorbed 118&215.7µg/cm2ft.respectively.Chronic Ef ects: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 /> inhalation may result in blood disorders,particularly leukopenia(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 Gft 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 /> Inhalatloo: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 akrt person drink I to 2 glasses of water
<br /> to dilute.Do not induce vomiting!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 /> After first aid,get appropriate In-plant,paramedic,or community medical support
<br /> Note to Physicians:BEI=mandelic acid in urine(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, teak,and Disposal Procedures
<br /> Sp1WL.eak: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 /> rial 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 1910.120). Environmental Transport:If released to soil,EB partially evaporates into the atmosphere,with a half-life
<br /> of hrs 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 air,it reacts with
<br /> photochemically produced hydroxyl radicals with a half-life of hrs to 2 days.Additional amounts may be removed by rain.Ecotoxlcity Values:
<br /> Shrimp(Hysidopsis bahia),LC5o=87.6 m&"6 hr;sheepshead minnow(Cyprinodon variegalus)LC5o=275 mVIB6 hr;fathead minnow
<br /> (Pimephaks pronzelas)LCA=42.3 m"6 hr in hard water&483 mg4/96 hr in softwater.Disposal:A candidate for rotary kiln incineration at
<br /> 1508 to 2912'F(820 to 1600'C),liquid injection incineration at 1202 to 2912T(650 to 1600'C),and fluidized bed incineration at 842 to 1796'F
<br /> (450 to 980'C).Contact your supplier or a licensed contractor for detailed recommendations.Follow applicable Federal,state,and local regulations.

<br /> s Section S. Special Protection Data
<br /> Goggles:Weir 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-purifying respirator with an appropriate organic vapor cartridge,a supplied-air respirator(SAR).SCBA,or chemical cartridge respirator with
<br /> appropriate organic vapor cartridge.For<2000 ppm,use a SAR or SCBA with a full facepiece.For emergency or nonroutine operations(cleaning
<br /> spills,reactor vessels,or storage tanks),wear an SCBA.Warning!Air par6ing respirators do not protect workers in oxygen-dtlieient 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 areas. Other:Wear chemically protective
<br /> I 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 conC=trations below the OSHA PELs(Sec.2).Local exhaust ventilation is preferred because it prevents
<br /> contaminant dispersion into the work area by controlling it at its source o') Safely Stations:Make available in the work area emergency
<br /> i eyewash stations,safety/quick-drench showers,and washing facilities. Contaminated Equipment:Separate contaminated work clothes from
<br /> street clothes and launder before reuse.Remove this material from your shoes and clean PPE. Comments:Never eat,drink,or smoke in work
<br /> areas.Practice good personal hygiene after using this material,especially before eating,drinking,smoking.using the toilet,or applying cosmetics.
<br /> Section 9. Special Precautions and Comilients
<br /> Storage Requirements:Store in a cool,dry,well.ventilated area away from ignition sources and oxidizers.Outside or detaiched 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,electrically ground and bond all equipment used with ethylbenzene.Install Class 1,Group D electrical equipment. Engineering
<br /> Controls:To reduce potential health hazards,use sufficient dilution or local exhaust ventilation to control airborne contaminants and to maintain
<br /> eal
<br /> levels as low as possible. Purge and ventilate reaction vessels before workers are allowed to enter for maintenance or cleanup. Administrative
<br /> Controls:Consider preplacement and periodic medical exams of exposed workers that emphasize the CNS,skin,blood,and respiratory system.
