<br /> 5cction 6 Health Hazard Data e
<br /> Medical Condltions Aggravated by bong Term Exposure Skin and CNS diseases and unpaired pulmonary function(especially obstructive '
<br /> ru a) disease) Target Organs Lyes,respiratory system skin CNS,blood Primary Entry Routes Inhalation skin and eye contact Acule
<br /> 1 ffects Vapor inhalation of 200 ppm caused transient eye irritation, 1000 ppm caused eye irritation with profuse watering(tolerance developed
<br /> r ip)dl)),2000 ppm caused severe and immediate eye irritation and watering nasal=1.14011,chest constrncuon and vcrugo,5000 ppm was
<br /> in'olerable and caused eye and nose irritation Inhalation of high concentrations may cause narcosis,cramps,and death due to respiratory paralysis
<br /> Skin exposed to pure ethylbenzene for 10 to 1.5 min 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/cm2/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 /> inhalation may result in blood disorders,particularly leukopenia(abnormally low level of white blood cells)and lymphocytosis
<br /> I'IRST AID
<br /> E~)es Do not allow victim to rub or keep eyes tightly shut.Gently lift eyelids and flush immediately and continuously with flooding amounts of e
<br /> w ater until transported to an emergency medical facility Consult a physician immediately Skin Quickly remove contaminated clothing Rinse
<br /> u ith 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 /> com ulsing person Contact a poison control center and unless otherwise advised,have that conscious and alert person dunk 1 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 BE[=mandelic acid in urine(1 5 g/g of creaunme),sample at end of shift at workweeks end.Since this test is not specific, I test for EB in expired air for confirmation i
<br /> Section 7. Spill, Leak, and Disposal Procedures
<br /> Spill/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 'fake 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 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 /> da)s Some EB may absorb to sedu-nent 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 Ecotoxicity Values

<br /> 1508 to 2912'F(820 to 1600'C),liquid infection incineration at 1202 to 2912'17(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 /> 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 Iens 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-au respirator(SAR) SCBA or chemical cartridge respirator with
<br /> appropriate organic%apor cartridge For<2000 ppm use a SAR or SOBA with a full facepiece For emergency or nonroutine operations(cleaning
<br /> spills reactor vessels,or storage tanks),wear an SCBA Warning f Air purtfying respirators do not protect workers in oxygen-deficient ainw
<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 /> gloves boots,aprons and'gauntlets made of Vrt6n or polyvinylchloride to prevent skin contact Ventilation Provide general and local exhaust
<br /> v enulation systems to maintain airborne concentrations 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 0031 Safety 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,dnnk,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 Comments ,
<br /> Storage Requirements Store in a cool,dry,well-venulated area away from ignition sources and oxidizers Outside or de-Latched 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 /> i 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 /> ]c,,cls as low as possible Purge and ventilate reaction vessels before workers are allowed to enter for maintenance or cleanup Adminlstrative
<br /> Controls Consider preplacement and periodic medical exams of exposed workers that emphasize the CNS skin blood and respiratory system
