**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Not available.
Potential Health Effects
Eye:
Vapors may cause eye irritation. May cause eye irritation and
possible burns.
Skin:
May cause skin irritation. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
Exposure may cause irritation characterized by redness, dryness, and
inflammation.
Ingestion:
May cause severe gastrointestinal tract irritation with nausea,
vomiting and possible burns.
Inhalation:
May cause irritation of the respiratory tract with burning pain in
the nose and throat, coughing, wheezing, shortness of breath and
pulmonary edema. May cause epiphoria, which is an excessive flow of
tears.
Chronic:
Chronic exposure can lead to iodism characterized by salivation,
nasal discharge, sneezing, conjunctivitis, fever, laryngitis,
bronchitis, stomatitis, and skin rashes. Chronic exposure can affect
thyroid function.
**** 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:
Flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists. Wash clothing before reuse.
Ingestion:
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:
Antidote:
None reported.
**** 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. Vapors may
be heavier than air. They can spread along the ground and collect
in low or confined areas.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Use water only!
**** 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. Provide
ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use with adequate ventilation. Avoid
contact with eyes, skin, and clothing. Keep container tightly closed.
Avoid ingestion and inhalation.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances. Keep containers tightly closed.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Good general ventilation should be sufficient to control airborne
levels.
