Section 3 - Hazards Identification

EMERGENCY OVERVIEW
Appearance: fine crystalline powder.
 Danger! Strong oxidizer. Contact with other
material may cause a fire. Causes eye, skin, and respiratory tract
irritation. Harmful if swallowed.
Target Organs: Respiratory system, eyes, skin.
Potential Health Effects
     
Eye:
          Contact with eyes may cause severe irritation, and possible eye
          burns.  May cause eye injury.
     
Skin:
          Causes skin irritation. May be harmful if absorbed through the skin.
     
Ingestion:
          Harmful if swallowed. May cause gastrointestinal irritation with
          nausea, vomiting and diarrhea.
     
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 be harmful if inhaled.
     
Chronic:
          Prolonged or repeated exposure may cause gastrointestinal irritation
          and kidney damage. Chronic exposure can lead to iodism characterized
          by headache, excess salivation, nasal discharge, conjunctivitis,
          laryngitis, bronchitis, stomatitis, enlarged submaxillary glands, and
          skin rashes. Chronic ingestion may cause central nervous system
          failure.

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 imme
          diately.
     
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.
     
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 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:
          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. Combustion generates toxic fumes. Use water with
          caution and in flooding amounts. Oxidizer. Greatly increases the
          burning rate of combustible materials. Vapors may be heavier than
          air.  They can spread along the ground and collect in low or confined
          areas.
     
Extinguishing Media:
          Use water spray, dry chemical, carbon dioxide, or chemical foam.
          Contact professional fire-fighters immediately.

Section 6 - Accidental Release Measures
 | 
     
General Information: Use proper personal protective equipment as indicated
                          in Section 8.
     
Spills/Leaks:
          Clean up spills immediately, observing precautions in the Protective
          Equipment section. Sweep up, then place into a suitable container for
          disposal. Avoid generating dusty conditions. Remove all sources of
          ignition. 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. Use with adequate ventilation. Minimize dust
          generation and accumulation. Avoid contact with clothing and other
          combustible materials. Do not get on skin or in eyes. Avoid
          ingestion and inhalation.
     
Storage:
          Do not store near combustible materials. Store in a cool, dry,
          well-ventilated area away from incompatible substances. Keep away
          from reducing agents.
  
    | 
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.
