FIRE DEGREDATION PRODUCTS: Oxides of carbon (CO,Co2).
FIRE EXTINGUISHING PROCEDURES:
Use DRY chemical, carbon dioxide, alcohol foam or water spray.
Water may be ineffective to extinguish fires. Wear adequate
personal protection to prevent contact with material or its
combustion products. Self contained breathing apparatus with a
full face piece operated in a pressure demand or other positive
pressure mode. Cool containing vessels with flooding quantities
of water.
FIRE AND EXPLOSION HAZARDS:
Flammable liquid. Vapors form from this product may travel or be
moved by air currents and ignited by pilot lights, other flames,
sparks, heaters, electrical equipment, static discharges or other
ignition sources at locations distant from handling point. Vapor
forms explosive mixture with air. Container explosion may occur
under fire conditions or when heated. Contact with oxidizers may
cause fire and/or explosion. Sensitive to static discharge.
This material may produce a floating fire hazard. May re-ignite
after fire is extinguished. Emits toxic fumes under fire
2
conditions.

TOXICOLOGICAL PROPERTIES
_________________________________________________________________
PRIMARY ROUTE(S) OF ENTRY: Inhalation and ingestion. Eye contact,
skin contact. Skin absorption.
EFFECTS OF ACUTE EXPOSURE:
Harmful by ingestion inhalation or skin absorption. Irritant.
Target organs: blood, ears, central nervous system, liver,
kidneys, eyes, skin, respiratory system.
EYES: Causes severe irritation. May cause severe burns and
loss of vision. May cause permanent damage. Redness,
keratoconjunctivitis, photophobia. Irritation: Eye-
rabbit 2 mg/24 hr SEVERE.
SKIN: Prolonged or repeated contact causes severe irritation,
defatting dermatitis. Can be absorbed in toxic
amounts, especially from prolonged or repeated
exposure.
INHALATION: Material is irritating to the mucous membranes and
upper respiratory tract. Causes nausea, vomiting,
headache, dizziness, weakness, fatigue, central nervous
system depression, and possible asphyxiation.
INGESTION: Can cause gastrointestinal disturbance. Headache,
vomiting, diarrhea, nausea, stupor, central nervous
system depression, liver and kidney damage possibility
of death by pulmonary aspiration of liquid.
EFFECTS OF CHRONIC OVEREXPOSURE:
Repeated or prolonged exposure to n-butyl alcohol at
concentrations above the TLV combined with high noise levels may
cause serious hearing loss in the form of auditory nerve and
vestibular injury. May cause dermatitis and lachymation.
Animal: anemia, liver, kidney, eye and lung damage. Detected in
maternal milk in human. To the best of our knowledge, the
chemical, physical, and toxicity of this substance has not been
fully investigated.

FIRST AID MEASURES
_________________________________________________________________
EYES: Immediately flush eyes with copious quantities of water
for at least 15 minutes holding lids apart to ensure
flushing of the entire surface. Seek medical
attention.
SKIN: Immediately flush skin with soap and water for at least
15 minutes while removing contaminated clothing and
3
shoes. Call a physician. Wash clothing before reuse.
INHALATION: Remove patient to fresh air. Administer approved
oxygen supply if breathing is difficult. Administer
artificial respiration or CPR if breathing has ceased.
Call a physician.
INGESTION: If conscious, wash out mouth with water. Have
conscious person drink several glasses of water to
dilute. DO NOT induce vomiting. Seek immediate
medical attention. Never give anything by mouth to an
unconscious person. Guard against aspiration into
lungs.

PREVENTATIVE MEASURES
________________________________________________________________
PROTECTIVE CLOTHING IN CASE OF SPILL AND LEAK:
Wear self contained breathing apparatus, rubber boots and heavy
rubber gloves.
SPILL/LEAKS PROCEDURES:
Evacuate the area. Eliminate all sources of ignition. Absorb on
sand or vermiculite and place in a closed container for
disposal. Ventilate area and wash spill site after material pick
up is complete. Use non-sparking tools. DO NOT empty into
drains. DO NOT touch spilled material.
WASTE DISPOSAL METHOD:
Burn in a chemical incinerator equipped with an after burner and
4
scrubber. According to all applicable regulations.
STORAGE AND HANDLING:
Store in a cool place away from heated areas, sparks, and flame.
Store in a well ventilated area. Store away from incompatible
materials. Do not add any other material to the container. Do not
wash down the drain. Do not breathe gas/fumes/vapor/spray. In case
of insufficient ventilation, wear suitable respiratory equipment.
Keep away from direct sunlight or strong incandescent light. Keep
container tightly closed and dry. Manipulate in a well ventilated
area or under an adequate fume hood. Take precautionary measures
against static discharges. Ground the container while dispensing.
Use only explosion proof equipment. Use non-sparking tools. Watch
for accumulation in low confined areas. Empty containers may contain
a hazardous residue. Handle and open container with care. Do not get
in eyes, on skin, or on clothing. Wash well after use. In accordance
with good storage and handling practices. Do not allow smoking and
food consumption while handling. Never use welding or cutting torch
on or near drum (even empty) because product (even just residue) can
ignite explosively. In case of accident or if you feel unwell, seek
medical advice immediately (show the label when possible.

PROTECTIVE MEASURES
________________________________________________________________
PROTECTIVE CLOTHING:
Safety goggles. Neoprene or nitrile rubber gloves. Impervious
apron, coveralls, and/or other resistant protective clothing.
Sufficient to protect skin. A OSHA/MSHA jointly approved
respirator is advised in the absence of proper environmental
controls. If more than TLV, do not breathe vapor. Wear
self-contained breathing apparatus. Do not wear contact lenses.
Make eye bath and emergency shower available.
ENGINEERING CONTROLS:
Local mechanical exhaust ventilation capable of maintaining
emissions at the of use below the lowest TLV. Use
explosion-proof ventilation equipment. Do not use in
infantility spaces.

SPECIAL PRECAUTIONS OR COMMENTS:
FLAMMABLE LIQUID! IRRITANT! Do not breathe vapor. Avoid all
contact with the product. Avoid prolonged or repeated exposure.
Manipulate in a well ventilated area or under an adequate fume
hood. Keep away from heat, sparks and flame. Take precautionary
measures against static discharges. Bond and ground transfer
containers and equipment to avoid static accumulation. Use
non-sparking tools. Handle and open container with care.

Container should be opened only by a technically qualified
person. Harmful to aquatic life at low concentrations. Can be
dangerous if allowed to drinking water intakes. Do not
contaminate domestic or irrigation water supplies, lakes,
streams, ponds, or rivers.
Synergistic materials: Alcohols may interact synergistically
with chlorinated solvents (example: carbon tetrachloride,
chloroform, bromotrichloromethane), dithiocarbamates (example:
disulfiram), aromatic hydrocarbons (example: xylene),
dimethylnitrosamine and thloacetamide.
Emergency Medical Care:
Butyl alcohol is especially toxic if aspirated. The vapors
appear to cause a special vacuolar kertopathy in humane.
There is no specific antidote. Treatment of overexposure
should be directed at the control of symptoms and the
clinical condition of the patient. This product contains
materials that may cause severe pneumonitis if aspirated.
If ingestion has occurred less than 2 hours earlier, carry
out careful gastric lavage; use endotracheal cuff if
available, to prevent aspiration. Observe patient for
respiratory difficulty from aspiration pneumonitis. Give
artificial resuscitation and appropriate chemotherapy if
respiration is depressed.
