*  Exposure Controls/Personal Protection  *
Respiratory Protection:IN DUST ENVIRONMENTS, THE USE OF A NIOSH/MSHA
    APPROVED RESPIRATOR IS RECOMMENDED.
Ventilation:LOCAL EXHAUST CAN BE USED, IF NECESSARY, TO CONTROL
    AIRBORNE DUST LEVELS.
Other Protective Equipment:BARRIER CREAMS, IMPERVOUS BOOTS AND
    CLOTHING. EMERGENCY EYE BATH AND DELUGE SHOWER .
Work Hygienic Practices:FOLLOWING WORK, WORKERS SHOULD SHOWER WITH SOAP
    & WATER.
Supplemental Safety and Health
MATLS TO AVOID:DIFLUORIDE MAY CAUSE FIRES. EFTS OF OVEREXP:POSSIBLY
    CANCER. SYMPTOMS OF EXCESSIVE EXPOSURE INCLUDE SHORTNESS OF BREATH
    AND REDUCED PULMONARY FUNCTION. THIS INERT MATERIAL GIVES NO POTE
    NTIAL ACUTE TOXIC HAZARD.

Effects of Overexposure:HLTH HAZ:ANIMALS INCLUDE, FOR ACUTE EXPOS,
    ALVEOLAR DAMAGE W/PULM EDEMA. CHRONIC:DUST CAN CAUSE INFLAMM OF
    LINING TISS OF INTERIOR OF NOSE & INFLAMM OF CORNEA. HYPERSENSITIVE
    INDIV MAY DEVELOP ALLERG  DERM. EXCESS INHAL OF SILICA DUST MAY
    RESLT IN RESP DISEASE, INCL SILICOSIS, PNEUMOCONIOSIS, PULM
    FIBROSIS & (SUPP DATA)
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH SENSITIVE SKIN AND
    WITH PULMONARY AND/OR RESPIRATORY DISEASE, INCLUDING, BUT NOT
    LIMITED TO, ASTHMA & BRONCHITIS, OR SUBJECT TO EYE IRRITATION,
    SHOULD BE PRECLUDED FROM EXPOSURE.
*  First Aid Measures  *
First Aid:EYE:IRRIGATE IMMEDIATELY AND REPEATEDLY WITH CLEAN WATER FOR
    APPLY STERILE DRESSINGS. INHAL:REMOVE PERSON IMMEDIATELY TO FRESH
    AIR, GIVE  ARTIFICIAL RESPIRATION AS NEEDED. GET MD. INGEST:CALL MD
    IMMEDIATELY .
*  Fire Fighting Measures  *
