**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Flammable. Harmful if swallowed. Irritating to respiratory system
and skin. Risk of serious damage to eyes. Vapors may cause
drowsiness and dizziness.

Potential Health Effects
Eye:
Causes severe eye irritation. May cause corneal edema and
inflammation. May cause lacrimation (tearing), blurred vision, and
photophobia.
Skin:
Causes skin irritation. Skin absorption is slight. Repeated or
prolonged exposure may cause drying and cracking of the skin.
Ingestion:
May cause central nervous system depression, characterized by
excitement, followed by headache, dizziness, drowsiness, and nausea.
Advanced stages may cause collapse, unconsciousness, coma and
possible death due to respiratory failure. Aspiration of material
into the lungs may cause chemical pneumonitis, which may be fatal.
May be harmful if swallowed.
Inhalation:
Causes respiratory tract irritation. May cause cardiovascular
disturbances, hearing abnormalities, central nervous system
depression, muscle weakness, and possible death due to respiratory
failure. May be absorbed through the lungs.
Chronic:
Prolonged or repeated skin contact may cause defatting and
dermatitis. May cause damage to the auditory nerve (some hearing
loss) and vestibular injury. Animal evidence suggests that
fetotoxicity and teratogenicity may be observed at doses that also
cause harmful effects in the mothers. The systemic toxicity of
n-butanol is low, although it may potentiate the hepatic (liver)
toxicity of other inhaled compounds, such as carbon tetrachloride.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid immediately.
Skin:
In case of contact, flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical aid if irritation
develops and persists. Wash clothing before reuse.
Ingestion:
Potential for aspiration if swallowed. Get medical aid immediately.
Do not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious person.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Alcoholic beverage consumption may enhance the toxic effects of this
substance. Persons with liver, kidney, or central nervous system
diseases may be at increased risk from exposure to this product.
Butanol is especially toxic if aspirated. Treat symptomatically and
supportively.

**** SECTION 5 - FIRE FIGHTING MEASURES ****

General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Use water spray to keep fire-exposed containers
cool. Flammable liquid and vapor. Vapors are heavier than air and may
travel to a source of ignition and flash back. Vapors can spread
along the ground and collect in low or confined areas.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or appropriate foam.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Remove all sources of ignition.
Provide ventilation. Use only non-sparking tools and equipment.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Use spark-proof tools and explosion proof equipment. Avoid
contact with eyes, skin, and clothing. Empty containers retain
product residue, (liquid and/or vapor), and can be dangerous. Do not
ingest or inhale. Do not pressurize, cut, weld, braze, solder,
drill, grind, or expose empty containers to heat, sparks or open
flames. Use only with adequate ventilation. Keep away from heat,
sparks and flame.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a cool, dry, well-ventilated area away from
incompatible substances.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower.
Personal Protective Equipment

Eyes:
Wear chemical goggles.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant a respirator's use.

in volatilization from the soil surface and biodegradation is
expected to be significant. n-Butanol should not bind strongly to
soil and so is expected to leach into groundwater. Release of
n-butanol to water is expected to result in biodegradation and in
volatilization from the water surface. Photooxidation by hydroxyl
radicals is expected to be slow.
