Health Hazards Acute and Chronic:ACUTE (SHORT TERM): FIBER GLASS WOOL
    IS A MECHANICAL IRRITANT AND MAY CAUSE TEMPORARY IRRITATION OF THE
    RESPIRATORY TRACT, SKIN AND EYES. CHRONIC (LONG TERM): FIBER GLASS
    WOOL IS A POSSIBLE CANCER HAZ ARD. USE OF THESE PRODUCTS HAS NOT
    BEEN SHOWN TO CAUSE CANCER IN HUMANS. FIBER GLASS WOOL CAUSED
    CANCER IN ANIMALS THROUGH UNNATURAL ROUTES OF EXPOSURE (SURGICAL
    IMPLANTATION), BUT HAS NOT PRODUCED  C ANCER BY INHALATION. SEE
    TOXICOLOGICAL INFORMATION FOR EXPLANATION OF THESE DATA.
Explanation of Carcinogenicity:FORMALDEHYDE: ACGIH A2: SUSPECTED HUMAN
    CARCINOGEN. FIBER GLASS WOOL: ACGIH A3: ANIMAL CARCINOGEN. SEE
    TOXICOLOGICAL INFORMATION FOR COMPLETE INFORMATION.
Effects of Overexposure:SEE HLTH HAZS. STATE REG INFO: THAT GLASS WOOL
    IS NOT LIKELY TO CAUSE CANCER IN HUMANS EXCEPT UNDER
    UNCOMMON/UNLIKELY RTES/LEVELS OF EXPOS. TLV-TWA OF 1 RESP FIBER/CC

    ANIMALS. THERE ARE 2 MAJOR TYPES OF AN IMAL STUDIES: 1) INHAL WHERE
    ANIMALS BREATH GLASS WOOL FIBERS, & 2) INSTILLATION STUDIES WHERE
    FIBERS ARE INJECTED/SURGICALLY IMPLANTED DIRECTLY INTO ANIMAL.
    PLEASE CONT NEHC FOR MORE COMPLETE INFO ONTOXICITY.
Medical Cond Aggravated by Exposure:CHRONIC RESPIRATORY OR SKIN

*  First Aid Measures  *
First Aid:INHAL: MOVE TO FRESH AIR. ADMINISTER CARDIAC/PULMONARY
    RESUSCITATION (CPR) IF PULSE IS NOT DETECTABLE/IF UNABLE TO
    BREATHE. PROVIDE OXYGEN IF BREATHING IS DIFFICULT. OBTAIN MED
    ASSIST IF IRRIT PERSIST S. EYES: FLUSH W/RUNNING WATER FOR AT LEAST
    & RUNNING WATER. USE WASH CLOTH TO HELP REMOVE FIBERS. TO AVOID
    FURTHER IRRIT, DO NOT RU B/SCRATCH IRRITATED AREAS.
    RUBBING/SCRATCHING MAY FORCE FIBERS INTO SKIN. SEEK MED ATTN IF
    IRRIT PERSISTS. INGEST: INGEST IS UNLIKELY. IF IT DOES OCCUR,
    OBSERVE INDIVIDUAL FOR SEVERAL DAYS TO INSURE T HAT INTESTINAL
    BLOCKAGE DOES NOT OCCUR.

    IN HUMANS). A NUMBER OF NEW EPIDEMIOLOGICAL STUDIES ON PERS IN
    VARIETY OF OCCUPATIONS W/POTENTIALEXPOS TO FORMALDEHYDE WERE USED
    IN EVALUATION. CANCERS THAT OCCURRED IN EXCESS IN MORE THAN ONE
