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

EMERGENCY OVERVIEW
Highly flammable. Reacts violently with water liberating extremely
flammable gases. Explosive with or without contact with air. Harmful
by inhalation.

Potential Health Effects
Eye:
Causes eye burns. May cause chemical conjunctivitis and corneal
damage.
Skin:
Causes skin burns. May cause cyanosis of the extremities. 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. May
cause gastrointestinal irritation with nausea, vomiting and
diarrhea. Causes gastrointestinal tract burns. May cause liver and
kidney damage. May cause perforation of the digestive tract. The
toxicological properties of this substance have not been fully
investigated. Ingestion of large amounts may cause CNS depression.
May cause systemic effects. Chronic ingestion of iodides during
pregnancy has resulted in fetal death, severe goiter, and cretinoid
appearance of the newborn.
Inhalation:
May cause liver and kidney damage. Causes chemical burns to the
respiratory tract. The toxicological properties of this substance
have not been fully investigated. Aspiration may lead to pulmonary
edema. Vapors may cause dizziness or suffocation. May cause systemic
effects. May cause burning sensation in the chest.
Chronic:
May cause liver and kidney damage. Effects may be delayed. Chronic
ingestion of iodides during pregnancy has resulted in fetal death,
severe goiter, and cretinoid appearance of the newborn. Prolonged
exposure to iodides may produce iodism in sensitive individuals.
Symptoms could include skin rash, running nose and headache.

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

Eyes:
Get medical aid. 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:
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. 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:
Evacuate area and fight fire from a safe distance. 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. May burn with invisible flame. 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. Containers may explode in the heat of a fire.
Flammable liquid and vapor. Spontaneously ignitable in air. Vapors
may be heavier than air. They can spread along the ground and
collect in low or confined areas.
Extinguishing Media:
Use dry sand or earth to smother fire. 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. 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. 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:
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. Isolate area and deny
entry. Provide ventilation. Place under an inert atmosphere. Do not
use combustible materials such as paper towels to clean up spill. A
vapor suppressing foam may be used to reduce vapors.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Ground and bond containers when
transferring material. Use spark-proof tools and explosion proof
equipment. 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. Do not ingest or inhale. Handle under an inert
atmosphere. 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. Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
Flammables-area. Do not expose to air. Store under an inert
atmosphere.

**** 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 general or
local explosion-proof ventilation to keep airborne levels to
acceptable levels.
