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

EMERGENCY OVERVIEW
Highly flammable. Reacts violently with water. Causes burns.Moisture
sensitive.Corrosive.Highly flammable.

Potential Health Effects
Eye:
Causes eye burns.
Skin:
Causes skin burns. Prolonged and/or repeated contact may cause
irritation and/or dermatitis.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns. May be harmful if swallowed.
Inhalation:
Causes chemical burns to the respiratory tract. Exposure produces
central nervous system depression. Vapors may cause dizziness or
suffocation.
Chronic:
Prolonged or repeated skin contact may cause dermatitis.

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

Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes or keep
eyes closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid immediately. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:

**** 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. Vapors may form an explosive mixture with air.
Vapors can travel to a source of ignition and flash back. During a
fire, irritating and highly toxic gases may be generated by thermal
decomposition or combustion. Use water spray to keep fire-exposed
containers cool. Extremely flammable liquid and vapor. Containers may
explode in the heat of a fire. Flammable liquid and vapor. Vapors may
be heavier than air. They can spread along the ground and collect in
low or confined areas. Will be easily ignited by heat, sparks or
flame.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. For large fires, use water spray, fog, or
alcohol-resistant foam. Do NOT use water directly on fire. Use water
spray to cool fire-exposed containers. Water may be ineffective. Use
agent most appropriate to extinguish fire. Do NOT use straight
streams of water.

**** 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. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation. A
vapor suppressing foam may be used to reduce vapors.

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

Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Ground and bond containers when transferring material. Avoid contact
with eyes, skin, and clothing. Empty containers retain product
residue, (liquid and/or vapor), and can be dangerous. Keep container
tightly closed. Keep away from heat, sparks and flame. Avoid
ingestion and inhalation. Discard contaminated shoes. Do not
pressurize, cut, weld, braze, solder, drill, grind, or expose empty
containers to heat, sparks or open flames.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Keep container closed when not in use. Store in a tightly
closed container. Store in a cool, dry, well-ventilated area away
from incompatible substances. Flammables-area. Water free area.

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

Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
