**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes burns.Corrosive.
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. Chronic
exposure can lead to iodism characterized by salivation, nasal
discharge, sneezing, conjunctivitis, fever, laryngitis, bronchitis,
stomatitis, and skin rashes.
**** 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
immediately.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
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. 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.
Notes to Physician:
**** 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.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant 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. Neutralize spill with a weak acid
such as vinegar or acetic acid. Clean up spills immediately,
observing precautions in the Protective Equipment section.
**** 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. Discard contaminated shoes.
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.

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 impervious gloves.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure. Wear an impervious apron.
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.

**** 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.

potassium, iodine, iodide ions (I-).
Hazardous Polymerization: Will not occur.
