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

EMERGENCY OVERVIEW
Reacts violently with water. Harmful by inhalation and if swallowed.
Causes burns. Toxic to aquatic organisms, may cause long-term adverse
effects in the aquatic environment.Water-reactive.Moisture
sensitive.Corrosive.

Potential Health Effects
Eye:
Contact with liquid is corrosive to the eyes and causes severe
burns.
Skin:
Contact with liquid is corrosive and causes severe burns and
ulceration.
Ingestion:
Harmful if swallowed. Causes gastrointestinal tract burns.
Inhalation:
Harmful if inhaled. Causes chemical burns to the respiratory tract.
Inhalation may be fatal as a result of spasm, inflammation, edema of
the larynx and bronchi, chemical pneumonitis and pulmonary edema.
Chronic:
Chronic inhalation and ingestion may cause chronic fluoride
poisoning (fluorosis) characterized by weight loss, weakness,
anemia, brittle bones, and stiff joints.

**** 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. If water-reactive products are embedded in the skin, no
water should be applied. The embedded products should be covered
with a light oil.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Get medical aid immediately.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing
is difficult, give oxygen. Get medical aid. Do NOT use mouth-to-mouth
resuscitation. If breathing has ceased apply artificial respiration
using oxygen and a suitable mechanical device such as a bag and a
mask.
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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Water
Reactive. Material will react with water and may release a flammable
and/or toxic gas. May ignite or explode on contact with steam or
moist air. May re-ignite after fire is extinguished.
Extinguishing Media:
Use dry sand or earth to smother fire. Substance is noncombustible;
use agent most appropriate to extinguish surrounding fire. DO NOT
USE WATER! Do NOT get water inside containers. Contact professional
fire-fighters immediately. Cool containers with flooding quantities
of water until well after fire is out.

**** 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. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Provide
ventilation. Do not expose spill to water.

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

Handling:
Wash thoroughly after handling. Do not allow water to get into the
container because of violent reaction. Avoid contact with eyes, skin,
and clothing. Avoid ingestion and inhalation. Do not allow contact
with water. Use only in a chemical fume hood. Keep from contact with
moist air and steam.
Storage:
Store in a cool, dry place. Store in a tightly closed container.
Keep under a nitrogen blanket. Keep away from water.

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

Engineering Controls:
Use explosion-proof ventilation equipment. Facilities storing or
utilizing this material should be equipped with an eyewash facility
and a safety shower. Use only under a chemical fume hood.
