Section 6 HeaEth Hazard Data ?2ccerd% studies snowed that TEL is first metabolized to ciethyl lead+ then over a pcnod of months conte ted to inorgaric lead%hich is then deposited in bone At this point chronic effects could rescmble those caused by direct exposure to inorganic Icad If victim sun i%es an ac.ite exposu.e recovery may tape weeks to months [tis questionable whether all changes are res ersiblc following hca%y or long term exposures Teratogenic effects may occur a syndrome with severe menta] retardation has been seen among children of hca%y gasoline sniffers (136) Medical Conditions Aggravated by Long-Term Exposure Mental disorders and hypertension Target Organs CICS cardio%asculzs stem eyes liver kidneys Primary Entry Routes Eye skin inhalation ingestion Acute Effects The primary target organ is the brain and S effects occur in three categories mild moderate,and severe Mild effects include anxiety imobihi:y insomnia,lund dreams vomiting taltic taste paleness cerebellar ataxia, and dianhea. Moderate effects are dtsortentauon hyperexcitability tremors chorea(tn%oluniary incoordination of face and limbs) bradycardia(slow heart action) hypotension(abnormally low blood pressure) and hypothcrmsa(lowered body temperature) Severe symptoms include delusions hallucinations mania,convulsions cerebellar edema(fluid in the brain) coma,and death Ringing in the cars impaired vision(due to weakening of the eye muscles) elevated liver enzymes,and anemia may also occur Chronic Effects May occur once TEL is metabolized to inorganic lead Symptoms include anemia, appetite loss weakness,insomnia, muscle and joint 1 pain and colic accompanied by severe abdominal pain See Genuan MSDS No 713 FIRST AID Eyes Do not allow victim to rub or keep eyes tightly shut.Gently lift eyelids and flush immediately and continuously with flooding amounts of water until transported to an emergency medical facility Consult a physician immediately Skin Quickly remo%e contarrti- nated clothing Rinse 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 Inhalation Remove exposed person to fresh air and support breathing as needed Ingestion Never gn a an)thing by mouth to an unconscious or convulsing person Contact a poison control center an unless otherwise advised,have that conscious and alert person dnnk 1 to 2 glasses of 1eater to dilute Induce vomiting only if large amounts are ingested Note to Ph)stcians Unne]cad levels are better indicators of exposure than blood lead levels Blood lead levels may not reflect exposure until toxicity is severe where as unne directly reflects amount of exposure In severe acute toxicity,unne lead levels are usually>3501tgIL but blood levels are<50µg/L Chelation therapy can be useful for chronic exposure but not for acute If blood levels are greater than 50µgldL begin chelation therapy with BAL calcium EDTA or D-penicillamine Section 7 Spill, Leak, and Disposal Procedures ' Spill/Leak Notify safety personnel isolate and ventilate area,deny entry and stay upwind Shut off ignition sources For small spills take up with earth sand vermiculite or charcoal absorbent(decreases evaporation)and place in suitable containers Dike far ahead of large spill neutral ize with agricultural(slaked)lime,sodium bicarbonate or crushed limestone and adjust to pH 7 Imestigate reclamation or disposal Follow applicable OSHA regulations(29 CFR 1910 120) Ecotoxicity Values Bluegill TLm=2 1 4 and 0 2 mg/L at 24 48 and 96 hr respectively En%ironmental Degradation In the atmosphere,TEL rapidly degrades by reaction with photochemically produced hydroxyl radicals and ozone molceul., The half life is-- 15 to 5 hr depending on solar intensity in water,volatilization is expected Half life from a model n%cr is 5 3 hr and 49 3 days in a model pond Itis also subject to hydrolysis and dueet photolysis Some TEL may degrade into dialkyl and trialkyl lead which may be more resistant to water than TEL itself Bioaccumulation may occur in aquatic organisms If released to soil some TEL is expected to degrade to %%atcr soluble compounds and leach although some may volatilize or undergo direct photolysis if exposed to sunlight Disposal Contact your supplier ora licensed contractor for detailed recommendauons Follow applicable Federal state and local regulations IM EPA Designations OSHA Designations Listed(as lead compounds)as a SARA Toxic Chemical(40 CFR 372 65) Listed as an Air Contaminant(29 CFR 1910 1000 Table Z 1-A) ted as a SARA
