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

EMERGENCY OVERVIEW
Reacts violently with water. Irritating to eyes, respiratory system
and skin.Water-reactive.

Potential Health Effects
Eye:
Causes eye irritation. When substance becomes wet or comes in
contact with moisture of the mucous membranes, it will cause
irritation. May cause chemical conjunctivitis.
Skin:
Causes skin irritation. Contact with skin causes irritation and
possible burns, especially if the skin is wet or moist.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause cardiopulmonary system effects.
Inhalation:
Causes respiratory tract irritation. Can produce delayed pulmonary
edema.
Chronic:
Effects may be delayed.

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

Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
before reuse. 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:
Never give anything by mouth to an unconscious person. Get medical
aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:
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. 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. Material gives a green color when in contact with flames.
Extinguishing Media:
Use dry sand or earth to smother fire. DO NOT USE WATER! Contact
professional fire-fighters immediately. 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:
Vacuum or sweep up material and place into a suitable disposal
container. Avoid runoff into storm sewers and ditches which lead to
waterways. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
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. Minimize dust generation and
accumulation. Avoid contact with eyes, skin, and clothing. Keep
container tightly closed. Avoid ingestion and inhalation. Use with
adequate ventilation. Handle under an inert atmosphere. Do not allow
contact with water. Wash clothing before reuse. Keep from contact
with moist air and steam.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Keep away
from water. Store under an inert atmosphere.

**** 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.

Personal Protective Equipment

Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
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 respirator use.
