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

EMERGENCY OVERVIEW
Appearance: White, hydroscopic solid Danger! Corrosive. Poison. May be
fatal if absorbed through the skin. Causes severe eye and skin burns.
Inhalation causes severe respiratory tract irritation with coughing a
nd burning pain, which may lead to lung inflammation. May be fatal if
swallowed. Ingestion causes digistive tract burns with severe pain, vo
miting, dirrhea, and shock.

Target Organs: None.

Potential Health Effects
Eye:
Causes severe eye burns.
Skin:
May be fatal if absorbed through the skin.
Causes skin burns.
May cause deep, penetrating ulcers of the skin.
Ingestion:
Harmful if swallowed.
Causes gastrointestinal tract burns.
Causes severe pain, nausea, vomiting, diarrhea, and shock.
Inhalation:
Irritation may lead to chemical pneumonitis and pulmonary edema.
Causes severe irritation of upper respiratory tract with coughing,
burns, breathing difficulty, and possible coma.
Chronic:
Prolonged or repeated skin contact may cause dermatitis.

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

Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower lids.

Skin:
Get medical aid immediately.
Immediately flush skin with plenty of soap and water for at least 15
minutes while removing contaminated clothing and shoes.
Discard contaminated clothing in a manner which limits further
exposure.
Ingestion:
Do NOT induce vomiting.
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person.

Treat symptomatically and supportively.
None reported.

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

General Information:
Wear appropriate protective clothing to prevent contact with skin
and eyes. Wear a self-contained breathing apparatus (SCBA) to
prevent contact with thermal decomposition products.
Use water with caution and in flooding amounts.
Contact with moisture or water may generate sufficient heat to
ignite nearby combustible materials.

container. Avoid generating dusty conditions.

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

Handling:
Wash thoroughly after handling.
Use with adequate ventilation.
Do not allow water to get into the container because of violent
reaction.
Do not get in eyes, on skin, or on clothing.
Do not ingest or inhale.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances.
Keep away from strong acids.
Keep away from water.
Keep away from metals.
Keep away from flammable liquids.
Keep away from organic halogens.

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

Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.

**** SECTION 10 - STABILITY AND REACTIVITY ****

Chemical Stability:
Stable.
Conditions to Avoid:
Incompatible materials, moisture, contact with water, acids.
Incompatibilities with Other Materials:
Generates large amounts of heat when in contact with water and may
steam and splatter. Reacts with mineral acids to form corresponding
salts; reacts with weak acids gases like hydrogen sulfide,
sulfur dioxide, and carbon dioxide; ignites when in contact with
cinnamaldehyde or zinc; and reacts explosively with a mixture of
chloroform and methane. Corrosive to metals such as aluminum, tin,
and zinc as well as to alloys such as steel, and may cause formation
of flammable hydrogen gas.
Hazardous Decomposition Products:
Toxic fumes of sodium oxide, sodium peroxide fumes.
Hazardous Polymerization: Has not been reported.
