       **** SECTION 2 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
May cause sensitization by inhalation and skin contact.

Potential Health Effects
    Eye:
         Causes eye irritation.  May cause conjunctivitis.
    Skin:
         Prolonged and/or repeated contact may cause irritation and/or dermatitis. May cause skin sensitization, an allergic reaction,which becomes evident upon re-exposure to this material.
    Ingestion:
         May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause allergic reaction.
    Inhalation:
         Causes respiratory tract irritation. May cause asthmatic attacks due to allergic sensitization of the respiratory tract. May cause asthma and shortness of breath.
    Chronic:
         Repeated exposure may cause sensitization dermatitis. Repeated exposure may cause allergic respiratory reaction (asthma). Chronic inhalation of dust may lead to restricted pulmonary function and interstitial fibrosis.

         **** 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.
    Skin:
         Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
    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.
    Inhalation:
         Remove from exposure to fresh air immediately. Get medical aid if cough or other symptoms appear.
    Notes to Physician: NA

       **** 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. Dusts at sufficient concentrations can form explosive mixtures with air. Material can spontaneously ignite (pyrophoric) when exposed to air at normal or slightly elevated temperatures. Flammable solid.
Extinguishing Media:
         Use dry sand or earth to smother fire. DO NOT USE WATER!

     **** 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.

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

    Handling:
         Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with skin and eyes. Keep container tightly closed. Avoid ingestion and inhalation.
    Storage:
         Keep away from sources of ignition. Keep from contact with oxidizing materials. Store in a cool, dry, well-ventilated area away from incompatible substances.

         **** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

    Engineering Controls:
         Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
    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 gloves to prevent skin exposure.
  Clothing:
  Wear appropriate protective clothing to prevent skin exposure.
         Respirators:
  Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a
  NIOSH or European Standard EN 149 approved respirator when necessary.
