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

                              EMERGENCY OVERVIEW
Irritating to eyes, respiratory system and skin.Moisture
sensitive.The toxicological properties of this material have not been
fully investigated.

Potential Health Effects
    Eye:
         Causes eye irritation.
    Skin:
         Causes skin irritation. May be harmful if absorbed through the skin.
         The toxicological properties of this material have not been fully
         investigated. May cause contact dermatitis.
    Ingestion:
         May cause gastrointestinal irritation with nausea, vomiting and
         diarrhea. The toxicological properties of this substance have not
         been fully investigated. May be harmful if swallowed.
    Inhalation:
         Causes respiratory tract irritation. The toxicological properties of
         this substance have not been fully investigated. May be harmful if
         inhaled.
    Chronic:
         May cause bone marrow abnormalities with damage to blood forming
         tissues. Administration of gallium to humans has caused metallic
         taste, skin rashes, and bone marrow depression.

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

    Eyes:
         In case of contact, immediately flush eyes with plenty of water for
         at least 15 minutes. Get medical aid.
    Skin:
         In case of contact, flush skin with plenty of water. Remove
         contaminated clothing and shoes. Get medical aid if irritation
         develops and persists. Wash clothing before reuse.
    Ingestion:
         If swallowed, do not induce vomiting unless directed to do so by
         medical personnel. Never give anything by mouth to an unconscious
         person. Get medical aid.
    Inhalation:
         If inhaled, remove to fresh air. If not breathing, give artificial
         respiration. If breathing is difficult, give oxygen. Get medical aid.
    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.
    Extinguishing Media:
         Do NOT use water, CO2, or halogenated extinguishers. Use dry
         chemical extinguishing agents, dry sand or dry ground dolomite.

               **** 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 generating dusty conditions. Provide ventilation. Do
         not get water inside containers. Cool material below 25&C to solidify
         before attempting cleanup. Protect metal construction as gallium will
         dissolve the metal/is corrosive to most metals.

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

    Handling:
         Wash thoroughly after handling. Avoid contact with eyes, skin, and
         clothing. Keep container tightly closed. Avoid ingestion and
         inhalation. Use with adequate ventilation. 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. Store
         protected from moisture.

         **** 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.
    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 a respirator's use.
