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

EMERGENCY OVERVIEW
Reacts violently with water. Causes severe burns. Contact with
combustible material may cause fire.Corrosive.Water-reactive.

Potential Health Effects
Eye:
Causes eye burns. When substance becomes wet or comes in contact
with moisture of the mucous membranes, it will cause irritation. May
cause permanent corneal opacification. May cause chemical
conjunctivitis and corneal damage.
Skin:
Causes skin burns. Contact with skin causes irritation and possible
burns, especially if the skin is wet or moist. May cause skin rash
(in milder cases), and cold and clammy skin with cyanosis or pale
color.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns. May cause perforation of the digestive
tract. May cause burns to the gastrointestinal tract. May cause
systemic effects. May cause nausea, vomiting, and diarrhea, possibly
with blood.
Inhalation:
Causes chemical burns to the respiratory tract. Aspiration may lead
to pulmonary edema. May cause systemic effects. May cause acute
pulmonary edema, asphyxia, chemical pneumonitis, and upper airway
obstruction caused by edema.
Chronic:
Effects may be delayed.

**** 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.
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:
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. 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. Strong oxidizer. Contact with other material may
cause fire. 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. Use water spray to keep fire-exposed containers cool. Use
water with caution and in flooding amounts. Vapors may be heavier
than air. They can spread along the ground and collect in low or
confined areas. May ignite or explode on contact with steam or moist
air. Containers may explode when heated.
Extinguishing Media:
Use dry sand or earth to smother fire. Use agent most appropriate to
extinguish fire. DO NOT USE WATER! 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. Remove all
sources of ignition. Provide ventilation. Do not expose spill to
water. Do not use combustible materials such as paper towels to
clean up spill.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Do not allow water to get into the container
because of violent reaction. Keep container tightly closed. Avoid
contact with clothing and other combustible materials. Do not get on
skin or in eyes. Do not ingest or inhale. Use with adequate
ventilation. Do not allow contact with water. Discard contaminated
shoes. Keep from contact with moist air and steam.
Storage:
Keep away from heat, sparks, and flame. Do not store near
combustible materials. Keep away from water. Corrosives 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.
