2000707 Unleaded Gasoline MODS No.467
<br /> Acute Effects
<br /> Inhalation:The vapor is discomforting to the upper respiratory tract and may be harmful if exposure is prolonged.
<br /> Inhalation hazard is increased at higher temperatures.Acute effects from inhalation of high concentrations of vapor
<br /> are pulmonary irritation,including coughing,with nausea;central nervous system depression-characterized by
<br /> headache and dizziness,increased reaction time,fatigue and loss of coordination.If exposure to highly concentrated
<br /> solvent atmosphere is prolonged this may lead to narcosis,unconsciousness,even coma and possible death.
<br /> WARNING:Intentional misuse by concentrating/inhaling contents may be lethal.High inhaled concentrations of
<br /> mixed hydrocarbons tpay produce narcosis characterized by nausea,vomiting and lightheadedness.Inhalation of
<br /> aerosols may produce severe pulmonary edema,pneumonitis and pulmonary hemorrhage. Inhalation of petroleum
<br /> hydrocarbons consisting substantially of low molecular weight species may produce irritation of mucous membranes,
<br /> incoordination,giddiness,nausea,vertigo,confusion,headache,appetite loss,drowziness,tremors and anesthetic
<br /> stupor.Massive exposures may produce central nervous system depression with sudden collapse and deep coma;
<br /> fatalities have been recorded.Imitation of the brain and/or apneic anoxia may produce convulsions.Although
<br /> recovery following overexposure is generally complete,cerebral micro-hemorrhage of focal post-inflammatory
<br /> scarring may produce eleptiform seizures some months after the exposure.Pulmonary episodes may include chemical
<br /> pneumonitis with edema and hemorrhage.The lighter hydrocarbons may produce kidney and neurotoxic effects.
<br /> Liquid paraffins may produce anesthesia and depressant actions leading to weakness,dizziness,slow and shallow
<br /> respiration,unconsciousness,convulsions and death.C,,paraffins may also produce polyneuropathy.Aromatic
<br /> hydrocarbons accumulate in lipid-rich tissues(typically the brain,spinal cord and peripheral nerves)and may produce
<br /> functional impairment manifested by nonspecific symptoms such as nausea,weakness,fatigue,vertigo;severe
<br /> exposures may produce inebriation or unconsciousness.Many of the petroleum hydrocarbons are cardiac sensitizers
<br /> and may cause ventricular fibrillations.
<br /> Eye:The liquid may produce eye discomfort and is capable of causing temporary impairment of vision and/or transient
<br /> eye inflammation,ulceration.The vapor is discomforting to the eyes.Petroleum hydrocarbons may produce pain after
<br /> direct contact with the eyes.Slight,but transient,disturbances of the corneal epithelium may also result.The aromatic
<br /> fraction may produce irritation and lachrymation.The material may produce moderate eye irritation leading to
<br /> inflammation.Repeated or prolonged exposure to irritants may produce conjunctivitis.
<br /> Skin:The material is moderately discomforting to the skin if exposure is prolonged.The material contains a
<br /> component that may be absorbed through the skin and may cause drying of the skin;which may lead to dermatitis
<br /> from repeated exposures over long periods.Toxic effects may result from skin absorption.Open cuts,abraded or
<br /> imitated skin should not be exposed to this material.The material may accentuate any pre-existing dermatitis
<br /> condition.
<br /> Ingestion:Considered an irah ely route of entry in commercial/industrial environments.The liquid may produce
<br /> gastrointestinal discomfort and may be harmful if swallowed.Ingestion may result in nausea,pain and vomiting.
<br /> Vomit entering the lungs by aspiration may cause potentially lethal chemical pneumonitis.Ingestion of petroleum
<br /> hydrocarbons may produce imitation of the pharynx,esophagus,stomach and small intestine with edema and mucosal
<br /> ulceration.Resulting symptoms include a burning sensation in the mouth and throat.Large amounts may produce
<br /> narcosis with nausea and vomiting,weakness or dizziness,slow and shallow respiration,swelling of the abdomen,
<br /> unconsciousness and convulsions.Myocardial injury may produce arrhythmias,ventricular fibrillation and
<br /> electrocardiographic changes.Central nervous system depression may also occur.Light aromatic hydrocarbons
<br /> produce a warn,sharp,tingling sensation on contact with taste buds and may anesthetize the tongue.Aspiration into
<br /> the lungs may produce coughing,gagging,and a chemical pneumonitis with pulmonary edema and hemorrhage.
<br /> Carcinogenicity:NTP,-Not listed;IARC-Group 2B,Possibly carcinogenic to humans;OSHA-Not listed;NIOSH-
<br /> Listed as carcinogen;ACGI R-Class A3,Animal carcinogen;EPA-Not listed;MAK-Not listed.
<br /> Chronic Effects:Chronic solvent inhalation exposures may result in nervous system impairment and liver and blood
<br /> changes.Prolonged or continuous skin contact with the liquid may cause defatting with drying,cracking,irritation and
<br /> dermatitis following.Chronic poisoning may occur from vapor inhalation or skin absorption.The most significant
<br /> toxic effect is insidious and irreversible injury to the blood-forming tissue by benzene.Leukemia may develop.
<br /> Chronic exposure may cause headache,fatigue,loss of appetite and lassitude with incipient blood effects including
<br /> anemia and blood changes.Gasoline"sniffing"has caused severe nerve damage.Repeated or prolonged exposure to
<br /> mixed hydrocarbons may produce narcosis with dizziness,weakness,irritability,concentration and/or memory loss,
<br /> tremor in the fingers and tongue,vertigo,olfactory disorders,constriction of visual field,paresthesias of the
<br /> extremities,weight loss and anemia and degenerative changes in the liver and kidney.Chronic exposure by petroleum
<br /> workers to the lighter'hydmcarbons has been associated with visual disturbances,damage to the central nervous
<br /> system,peripheral neuropathies(including numbness and paresthesias),psychological and neurophysiological deficits,
<br /> bone marrow toxicities(including hypoplasia,possibly due to benzene)and hepatic and renal involvement.Chronic
<br /> dermal exposure to petroleum hydrocarbons may result in defatting which produces localized dermatoses.Surface
<br /> cracking and erosion may also increase susceptibility to infection by microorganisms.
<br /> Inhalation:Remove to fresh air.Lay patient down. Keep warm and rested.
<br /> If breathing is shallow or has stopped,ensure clear airway and apply resuscitation. Transport to hospital,or doctor.
