<br /> arc pogo c q: ut benzene as,respectively,x nipecLed human carcinogen,a cancer hAzAr on
<br /> sufficient human and animatl evidence,a human carcinogen(Group 1).
<br /> _Summary of Risks: Ptnlonged skin contact or excessive irLfWat.ion of benzene vapor may cause headache,wealmess,apper;tc,loss, and fatigue.
<br /> rile most important health hazards are cancer(cukemia)and bone marrow damage with injury to blood-forming tissue from chronic low-level
<br /> ppoose sure. Higher level exposures may irritate the respiratory tract and caucentral nervous system(CNS)depression.
<br /> iedkal Conditlons Aggravated b7 L44-Term Exposure:Exposure may worsen ailments of the heart,lungs,liver,kidneys,blood,and CNS.
<br /> arget Orrggaas:Blood,central nervous system,bone marrow,eyes,upper respiratory tract,and skin.
<br /> Primer Entry Routes Inhalation,skin contact
<br /> Acute 1:�Rectt;Symptoms of acute overexposure include irritation of the ryes,nose,and respiratory tract,breathlessness,euphoria,nausea,
<br /> drowsiness,headache,diz Liness,and intoxication.Severe expostire may lead to convulsions and unconsciousness.Skin contact may cause a
<br /> drying rash(dematitis).
<br /> Cbroolt Effects:Long-tenet chronic exposure may result in many blood disorders ranging from aplastic astomia(an inability to form blood cells)
<br /> to kukemia,
<br /> FIRST AID
<br /> Eyes:Gently lift the eyelids and flush immediately and continuously with flooding amounts of water until transported to an unergcnry medical
<br /> facility.Consult s physician immediately.
<br /> Skin:Qukity remove contaminated clothing.Immediately rinse with flooding amounts of water for at least 15 min.For reddened or blista:red
<br /> skin,consult a physician.Wash affected area with soap and water,
<br /> Inbalation:Remove exposed person to fresh air.Emergency personnel should protect agshut inhalation exposure.Provide CPR to support
<br /> breathing or circulation as necessary.Keep awake and trtmsport to a medical facIty
<br /> Ingestion:Never$ive anything by mouth to an unconscious or convulsing person If ingested,do+sol i.tduce vomiting since aspiration may be
<br /> fatal.Call s p�I�tysictan immediatelyy
<br /> After first acid,get apppropriate In-plant,paramedic,or community medical support.
<br /> PbyAclan's Note:Evai]uatc chronic exposure with a CBC,peripheral smear,and reticukrcyte count for signs of myclotoxicity.Follow up any 1
<br /> early indicators of leukemia with a bone marrow biopsy.Urinary phenol conjugates may be used for biological monitoring oftecant exposure. l
<br /> Acute managerniatt is primarily supportive for CNS depmssxm

<br /> Sp1ln/ sk:Design and practice a benzene spill control and countermeasure plan(SCCP).Notify safety personnel,evacuate all unnecessary
<br /> pcsannel,eliminate all heat and ignition sources,and provide adequate ventilation.Cleanup personnel should protect against ver inhalation,eye
<br /> 1 contact,and skin absorption.Absorb as much benzene u possible with an inert,noncombustible material-For large spills,dike frahead of spill
<br /> 'acrd contain liquid.Use nonsparking tools to place waste liquid or absorbent into closable containers for disposal.Keep waste out of confined
<br /> spaces such as sewers,watersheds,and waterways because of explosion danger.Follow applicable OSHA regulations(29 CFR 1910.120).
<br /> Disposal:Contact your supplier or a licensed contractor for detailed recommendations.Follow applicable Federal,state,and local regulations.

<br /> -Respirator:Seek profemlonal advice prior to respirator seleWon and use.Follow OSHA respirator regulations(29 CFR 1910.134)and,if neces-
<br /> sary wear a NIOSH-approved respirator.For emergency or nonroutine operations(cleaning spills,reactor vessels,or storage tanks),wear an
<br /> SOBA.Warning!Air-purifying respirators do not protect workers in oxygen-deficient abnospherer.
<br /> Other:Wear impervious gloves,boots,aprons,and gauntlets to prevent skit contact.
<br /> ..VentBatiow Provide genual and local explosion-proof ventilation systems to maintain airborne concentrations at least below the OSHA PELs
<br /> (Sec.2).Local exhaust ventilation is preferred since it prevents contarnirnant dispersion into the work area by controlling it aL its source.00)
<br /> Safety Stations:Make available in the work area emergency eyewash stations,safetylquick-drench showers,and washing facilities.
<br /> Contaminated Equipment:Never wear contact lestses in the work area:soft lenses may absorb,and all lenses concentrate,irritants.Remove this
<br /> matrnal from your shoes and equipment.Lat
<br /> Launder contaminated clouting before wearing.

<br /> Storage Requirements:Store in tightly closed containers in a cool,dry,well ventilated arta away from all heat and ignition sources and.
<br /> incompatible matuials.Caution!Benzete vapor may form explosive mistwes in air,To prevent static sparks,electrically ground and bond all
<br /> containers and equipment used in shipping,reuivtng,or transferring operations in prodmtion and storage areas.When opening or closing
<br /> benume containers,use noncparking tools.Keep fire extin&shers readily available.
<br /> Engineering Controls:Because OSHA specifically regulates benzene(29 CFR 1910.1028),educate workers about its potential hazards and
<br /> `danlicn.Minimize ail possible exposures to carcinogens.If possible,substitute lest toxic solvents for beri ene:use this material with extrt:me
<br /> caution and only if absolutely essential.Avoid vapor inhalation and skin and eye contact Use only with adequate ventilation and appropriate
<br /> onal protective gem.Institute a rcapiratory protection program that include maintenance,
<br /> regular training. uupection,and evaluation.
<br /> gnate regulated areas of benzene use(see legend in the box below)and label benzene containers with"DANGER.CONTAINS BENZENE,
<br /> CANCER HAZARD."
<br /> Other Precautions:Provide preplacement and periodic medical examinations with emphuis on a history of blood disease or previous exposure.
