                            FIRE AND EXPLOSION DATA

FIRE AND EXPLOSION HAZARD:
Dangerous fire hazard when exposed to heat or flame.

Vapors are heavier than air and may travel a considerable distance to a source
of ignition and flash back.

Vapor-air mixtures are explosive above flash point.

FLASH POINT: >57 F (>14 C)    UPPER EXPLOSIVE LIMIT: 19% (ethanol)

LOWER EXPLOSIVE LIMIT: 3.3% (ethanol)    FLAMMABILITY CLASS(OSHA): IB

FIREFIGHTING MEDIA:
Dry chemical, carbon dioxide, water spray or alcohol-resistant foam
(1993 Emergency Response Guidebook, RSPA P 5800.6).

For larger fires, use water spray, fog or alcohol-resistant foam
(1993 Emergency Response Guidebook, RSPA P 5800.6).

FIREFIGHTING:
Move container from fire area if you can do it without risk. Dike fire-control
water for later disposal; do not scatter the material. Apply cooling water to
sides of containers that are exposed to flames until well after fire is out.
Stay away from ends of tanks. Withdraw immediately in case of rising sound
from venting safety device or any discoloration of tank due to fire. Isolate
for 1/2 mile in all directions if tank, rail car or tank truck is involved in
fire (1993 Emergency Response Guidebook, RSPA P 5800.6, Guide Page 28).

Extinguish only if flow can be stopped. Use flooding amounts of water as a
fog; solid streams may be ineffective. Cool containers with flooding amounts
of water from as far a distance as possible. Avoid breathing poisonous vapors,
keep upwind.

                         HEALTH EFFECTS AND FIRST AID

INHALATION:
ETHYL ALCOHOL (ETHANOL):
IRRITANT/NARCOTIC.
  ACUTE EXPOSURE- Exposure of humans to 1000-10,000 ppm has caused temporary
    irritation of the upper respiratory tract and coughing; and if continued,
    central nervous system depression with headache, stupor, fatigue,
    dizziness, drowsiness, dullness, lassitude and loss of appetite may occur.
    A level of 20,000 ppm was considered just tolerable, and above this level,
    the atmosphere was described as intolerable and suffocating on even brief
    exposures. Additionally, exposure of animals to various concentrations
    has resulted in excitation followed by ataxia, incoordination,
    prostration, twitching, general paralysis, dyspnea, and occasionally
    death due to respiratory failure.
  CHRONIC EXPOSURE- Repeated or prolonged inhalation of vapors may cause
    irritation of the mucous membranes, headache, dizziness, nervousness,
    tremors, fatigue, nausea, narcosis, lack of concentration, and somnolence.
    Tolerance may be a factor in individual response to a given air
    concentration. Reproductive effects have been reported in animals.

METHYL ALCOHOL (METHANOL):
NARCOTIC/NEUROTOXIN. 25,000 ppm Immediately Dangerous to Life or Health.
  ACUTE EXPOSURE- May cause irritation of the mucous membranes, coughing,
    oppression in the chest, tracheitis, bronchitis, tinnitus, unsteady
    gait, twitching, colic, constipation, nystagmus, and blepharospasm.
    Symptoms from occupational exposure include paresthesias, numbness and
    shooting pains in the hands and forearms. Metabolic acidosis, and effects
    on the eyes and central nervous system may occur as detailed in acute
    ingestion.
  CHRONIC EXPOSURE- Repeated or prolonged exposure may cause effects as in
    acute ingestion. Repeated exposure to 200-375 ppm caused recurrent
    headaches in workers. Exposure for 4 years to 1200-8000 ppm resulted in
    marked diminution of vision and enlargement of the liver in a workman.
    Reproductive effects have been reported in animals.

METHYL ISOBUTYL KETONE:
IRRITANT/NARCOTIC.
3000 ppm Immediately Dangerous to Life or Health.
  ACUTE EXPOSURE- Vapor concentrations of 100 ppm may cause headache and
    nausea. Exposure to 200 ppm may be irritating to the respiratory tract.
    Exposure to concentrations >50 ppm may cause gastrointestinal effects
    such as nausea, vomiting, loss of appetite and diarrhea. Higher levels
    may cause central nervous system depression with lightheadedness,
    dizziness, dullness, incoordination, ataxia, unconsciousness, coma and
    death. Exposure of rats to 4000 ppm/4 hours caused death while 2000 ppm/
    4 hours was not lethal. Fatty livers and congestion of the brain, lungs
                 University of California  -  MSDS System              PAGE    7
                                                                        05/03/96
    and spleen were noted in animals dying after exposure to 28000 ppm/45
    minutes.
  CHRONIC EXPOSURE- Workers exposed to 80-500 ppm for 30 minutes per day
    complained of throat irritation, weakness, loss of appetite, headache,
    nausea, and vomiting. A few workers experienced insomnia, somnolence,
    heartburn, intestinal pain and slight liver enlargement. Exposure of rats
    to 100 ppm/90 days resulted in heavier livers and kidneys with reversible
    nephrosis of the kidneys. Exposure of rats to 20-30 ppm/4 hours/day for
    4 and 1/2 months caused disturbances in conditioned reflexes,
    interference with detoxifying function of the liver and elevated
    eosinophil count. Minimal distal axonal changes resulted from exposure
    to 1500 ppm for 5 months. Exposure of pregnant rats and mice to 3000 ppm
    produced a significant decrease in fetal body weight and retardation of
    skeletal ossification in the fetuses.

ETHYL ACETATE:
IRRITANT/NARCOTIC. 2000 ppm Immediately Dangerous to Life or Health.
  ACUTE EXPOSURE- Inhalation of 400 ppm for 3-5 minutes has caused respiratory
    tract irritation in humans. Low vapor concentrations may also cause
    headache, coughing, dizziness, drowsiness, and shortness of breath. High
    concentrations may cause narcotic effects with anesthesia and
    unconsciousness and renal and hepatic damage. Pathologic findings have
    included marked hyperemia of the respiratory tract, pulmonary edema,
    hemorrhagic gastritis, and hyperemia of the spleen and kidneys.
  CHRONIC EXPOSURE- No adverse symptoms were observed in workers exposed to
    375-1500 ppm for several months. Animal studies indicate that 4450 ppm
    for 1 hour daily for 40 days caused secondary anemia, leukocytosis, and
    liver and kidney damage. A 10-day vapor inhalation study in rats resulted
    in decreased motor activity and affects in breathing rates when exposed
    to >3000 ppm. In rare instances, repeated exposure may result in
    sensitization with mucous membrane irritation and eczematous eruptions.

FIRST AID- Remove from exposure area to fresh air immediately. Perform
  artificial respiration if necessary. Keep person warm and at rest. Treat
  symptomatically and supportively. Get medical attention immediately.

SKIN CONTACT:
ETHYL ALCOHOL (ETHANOL):
IRRITANT.
  ACUTE EXPOSURE- Direct contact may cause mild redness and burning.
    Sensitization has occasionally been reported to occur in some individuals
    resulting in allergic contact dermatitis in the form of eczematous
    eruptions or, rarely, erythematous flush or contact urticaria at the
    exposed site. Animal studies indicate that, depending on concentration
    and duration of exposure, varying degrees of irritation may occur
    ranging from mild to severe. Skin absorption may also occur.
  CHRONIC EXPOSURE- Repeated or prolonged contact with the liquid can cause
    defatting of the skin, producing a dry, fissured dermatitis, or other
    symptoms as in acute exposure. A 21-day modified Draize open test study
    resulted in no irritation in men, whereas an occlusive test resulted in
    erythema and induration toward the end of the exposure period.

METHYL ALCOHOL (METHANOL):
IRRITANT/NARCOTIC/NEUROTOXIN.
  ACUTE EXPOSURE- Contact with liquid may cause irritation. Skin absorption
    may occur and cause metabolic acidosis and effects on the eyes and central

    dermatitis. Chronic absorption may result in metabolic acidosis and
    effects as detailed in acute ingestion.

METHYL ISOBUTYL KETONE:
IRRITANT.
  ACUTE EXPOSURE- Vapor may cause irritation with redness. 500 mg applied to
    rabbit skin produced moderate irritation with transient erythema.
  CHRONIC EXPOSURE- Repeated or prolonged skin contact may cause defatting
    of the skin with primary irritation and desquamation. Exposure to vapor
    concentrations of 80-500 ppm has also been reported to cause dermatitis.

ETHYL ACETATE:
IRRITANT.
  ACUTE EXPOSURE- Direct contact with the liquid may cause irritation with
    redness and defatting action on the skin.
  CHRONIC EXPOSURE- Repeated or prolonged exposure may cause defatting
    dermatitis. In rare instances, repeated exposure may result in
    sensitization with eczematous eruptions.

FIRST AID- Remove contaminated clothing and shoes immediately. Wash with
  soap or mild detergent and large amounts of water until no evidence of
  chemical remains (at least 15-20 minutes). Get medical attention
  immediately.

EYE CONTACT:
ETHYL ALCOHOL (ETHANOL):
IRRITANT.
  ACUTE EXPOSURE- Vapor concentrations of 1,000-10,000 ppm may cause
    temporary eye irritation, with 15,000 ppm causing continuous tearing.
    Direct contact with the liquid may cause immediate burning and stinging,
    with reflex closure of the lids, tearing, temporary injury of the corneal
    epithelium, and hyperemia of the conjunctiva. Healing is usually
    spontaneous and complete. Depending on the concentration, contact with
    rabbit eyes causes a response ranging from mild irritation to severe
    injury. Irrigation of rabbit eyes with a 10% solution for several
    minutes caused no serious disturbances.
  CHRONIC EXPOSURE- Repeated application to rabbit eyes of 40-80% solutions
    caused corneal cloudiness, conjunctival necrosis, and loss of corneal
    epithelium and endothelium, followed by conjunctival hemorrhaging and
    edema, and infiltration and vascularization of the corneal stroma.

METHYL ALCOHOL (METHANOL):
IRRITANT.
  ACUTE EXPOSURE- Vapors may cause irritation. High concentrations have
    been reported to cause violent inflammation of the conjunctiva and
    epithelial defects on the cornea. Mild irritation may occur with
    dilute solutions; the undiluted liquid has produced moderate corneal
    opacity and conjunctival redness in rabbits. Application of a drop
    of methanol in rabbit eyes caused a mild reversible reaction, graded
    3 on a scale of 1-10 after 24 hours.
  CHRONIC EXPOSURE- Repeated or prolonged contact may cause conjunctivitis.

IRRITANT.
  ACUTE EXPOSURE- Vapor concentrations of 200 ppm are irritating to the eyes.
    Direct contact with liquid may cause pain and irritation. Exposure of
    >1000 ppm to guinea pigs caused severe irritation with lacrimation.
  CHRONIC EXPOSURE- Repeated or prolonged contact with irritants may cause
    conjunctivitis.

ETHYL ACETATE:
IRRITANT.
  ACUTE EXPOSURE- Direct contact with the liquid may cause irritation, with
    redness, pain, and lacrimation. Exposure to 400 ppm may cause a sensation
    of irritation in humans. Application of 2 drops to rabbit corneas,
    followed 2 minutes later by rinsing with water, caused immediate fine
    optical irregularity of the corneal epithelium, which returned to normal
    in 2 days.
  CHRONIC EXPOSURE- Repeated or prolonged exposure may cause conjunctivitis
    and cornea clouding. Rabbits exposed to the vapor at levels which would
    be scarcely tolerable to humans caused no corneal damage despite being
    exposed for 8 hours/day for 5 days/week for up to 7 weeks.

FIRST AID- Wash eyes immediately with large amounts of water or normal saline,
  occasionally lifting upper and lower lids, until no evidence of chemical
  remains (at least 15-20 minutes). Get medical attention immediately.

INGESTION:
ETHYL ALCOHOL (ETHANOL):
NARCOTIC/HEPATOTOXIN.
  ACUTE EXPOSURE- Ingestion may cause emotional lability and decreased
    inhibitions, with exhilaration, boastfulness, talkativeness, remorse,
    and belligerency; followed by gradual visual impairment, muscular
    incoordination, slowing of reaction time, sensory disturbances, and
    slurring of speech. Other symptoms may include flushing of the face,
    dilated pupils, rapid pulse, nausea, vomiting, sweating, and diuresis.
    Ingestion of large amounts may cause confusion, disorientation, loss
    of motor nerve control, shallow respiration, involuntary defecation
    and urination, drowsiness, stupor, and possibly coma. Convulsions
    due to hypoglycemia and shock with hypotension, tachycardia, cold
    pale skin, hypothermia, respiratory depression, and decreased reflexes
    may occur. Death may occur from respiratory or circulatory failure
    or later from aspiration pneumonitis or pulmonary edema. Recovery
    may be accompanied by headache, insomnia, gastritis, infection,
    restlessness, psychoses with uncontrollable fear, and visual, auditory,
    or gustatory hallucinations, exaggerated reflexes, tachycardia, and
    convulsions. Some individuals sensitized by external contact may
    suffer from a generalized erythema, stomatitis, urticaria, angioedema,
    morbilliform eruptions, or eczematous dermatitis at sites previously
    affected by external contact. Reproductive effects have been reported
    in animals.
  CHRONIC EXPOSURE- Chronic intoxication may result in weight loss,
    degenerative changes in the liver, kidneys, and brain, gastroenteritis
    with anorexia and diarrhea, and cirrhosis of the liver. Polyneuritis with
    pain, motor and sensory loss in the extremities, and optic atrophy may
    occur. Amnesia, tremors, confusion, impaired judgement, and loss or
    impairment of mental abilities are possible. Many years of chronic
    ingestion have caused acute myopathy with tenderness, aching, edema, and
    degeneration of the muscles. The heart may be affected, causing

                                                                        05/03/96
    palpitations, extrasystole, tachycardia, or other arrhythmias, which may
    progress to irreversible myocardial fibrosis and circulatory failure.
    ethyl alcohol has been clearly demonstrated to cause reproductive effects.
    The newborns of alcoholic mothers may exhibit fetal alcohol syndrome with
    low birth weights, prominence of the forehead and mandible, cleft palate,
    maxillary hypoplasia, short palpebral fissures, microphthalmia, epicanthal
    folds, severe growth retardation, mental retardation, microcephaly,
    cardiac anomalies, and possibly malorientation of the brain. 9 newborns
    of a high risk group, that is women who drink more than 2 ounces per day,
    showed increased tremors and non-alert wake states and decreased vigorous
    activity. Reproductive effects have also been reported in animals. Human
    consumption of alcoholic beverages has been causally related to the
    occurrence of malignant tumors of the oral cavity, pharynx, larynx,
    esophagus and liver.

METHYL ALCOHOL (METHANOL):
NARCOTIC/NEUROTOXIN.
  ACUTE EXPOSURE- May cause mild and transient inebriation and subsequent
    drowsiness followed by an asymptomatic period lasting 8-48 hours.
    Following the delay, coughing, dyspnea, headache, dullness, weakness,
    vertigo or dizziness, nausea, vomiting, occasional diarrhea, anorexia,
    violent pain in the back, abdomen, and extremities, restlessness, apathy
    or delirium, and rarely, excitement and mania may occur. Rapid, shallow
    respiration due to metabolic acidosis, cold and clammy skin, hypotension,
    cyanosis, opisthotonos, convulsions, mild tachycardia, cardiac depression,
    peripheral neuritis, cerebral and pulmonary edema, unconsciousness, and
    coma are possible. Effects on the eye may include optic neuritis, blurred
    or dimmed vision, dilated, unresponsive pupils, ptosis, eye pain,
    concentric constriction of visual fields, diplopia, change in color
    perception, photophobia, and optic nerve atrophy. Partial blindness or
    possibly delayed transient or permanent blindness may occur. Bilateral
    sensorineural deafness has been reported in a single case. Liver, kidney,
    heart, stomach, intest
inal and pancreatic damage may also occur. Death
    may be due to respiratory failure or rarely from circulatory collapse.
    As little as 15 ml has caused blindness; the usual fatal dose is
    60-240 ml. Prolonged asthenia and irreversible effects on the nervous
    system including difficulty in speech, motor dysfunction with rigidity,
    spasticity, and hypokinesis have been reported.
  CHRONIC EXPOSURE- Repeated ingestion may cause visual impairment and
    blindness and other systemic effects as detailed in acute ingestion.
    Reproductive effects have been reported in animals.

METHYL ISOBUTYL KETONE:
NARCOTIC.
  ACUTE EXPOSURE- May cause coughing, gastroenteritis, and central nervous
    system depression with headache, dizziness, dullness and vomiting.
  CHRONIC EXPOSURE- No data available.

ETHYL ACETATE:
NARCOTIC.
  ACUTE EXPOSURE- Ingestion of small amounts may cause sore throat, abdominal
    pain, and diarrhea. Large amounts may cause central nervous system
    depression, with dizziness, headache, weakness, fatigue, drowsiness, and
    unconsciousness. Poisoning may cause congestion of the liver and kidneys.
  CHRONIC EXPOSURE- Animals fed 1000 mg/kg for 1 month showed no effects.
                 University of California  -  MSDS System              PAGE   11
                                                                        05/03/96

FIRST AID- Qualified medical personnel should consider the following: Perform
  gastric lavage. If this can not be done immediately, proceed with the
  following: Induce emesis with syrup of ipecac and water. When vomiting
  occurs, keep head lower than hips to help prevent aspiration. Do not give
  anything by mouth or induce vomiting if person is unconscious or otherwise
  unable to swallow. Treat symptomatically and supportively. Get medical
  attention immediately.

ANTIDOTE:
The following antidote has been recommended. However, the decision as to
whether the severity of poisoning requires administration of any antidote and
actual dose required should be made by qualified medical personnel.

ETHANOL POISONING:
Naloxone, 0.01 mg/kg, intravenously, has an arousal effect in acute alcoholic
coma (Dreisbach, Handbook of Poisoning, 11th Ed.). Antidote should be
administered by qualified medical personnel.
