Effects of Overexposure:HLTH HAZS: ADVICE. SILICON DIOXIDE:
EPIDEMIOLOGICAL STUDY WAS CONDUCTED WHICH INCLUDED 165 PRECIPITATED
SILICA WORKERS WHO HAD BEEN EXPOSED FOR AVERAGE OF 18 YRS. NO
ADVERSE EFTS WERE NOTED IN COMPLET E MED EXAMINATION (INCL CHEST
ROENTGONOGRAMS) OF THESE WORKERS. PULM FUNC DECREMANTS WERE
CORRELATED ONLY W/SMOKING & AGE BUT NOT W/DEGREE OR DURATION OF
DUST EXPOS. LAB STUDIES HAVE ALSO BEEN CONDUCT ED IN SMALL ANIMALS
VIA INHAL TO LEVELS OF PRECIPATED SILICA DUST OF UP TO 126 MG/M3
FOR PERIODS FROM SIX MONTHS TO TWO YRS. ALTHOUGH PRECIPITATED
SILICA WAS TEMPORARILY DEPOSITED IN ANIMAL LUNGS, (SU PDAT)
Medical Cond Aggravated by Exposure:SILICON DIOXIDE: PERSONS
W/BREATHING PROBLEMS OR LUNG DISEASE SHOULD NOT WORK IN DUSTY AREAS
UNLESS A PHYSICIAN APPROVES AND CERTIFIES THEIR FITNESS TO WEAR
NIOSH APPROVED RESPIRATORY PROTECTION.

First Aid:EYE CONTACT: IMMEDIATELY RINSE WITH CLEAN WATER FOR AT LEAST
15 MINUTES. RETRACT EYELIDS OFTEN. SEEK MEDICAL ATTENTION. SKIN
CONTACT: IMMEDIATELY REMOVE CONTAMINATED CLOTHING. WASH SKIN
THOROUGHLY WIT H MILD SOAP AND WATER. FLUSH WITH LUKEWARM WATER FOR
15 MINUTES. SEEK MEDICAL ATTENTION. INHALATION: IF OVERCOME BY
EXPOSURE, REMOVE VICTIM TO FRESH AIR. IF BREATHING IS DIFFICULT OR
HAS STOPPED, ADMI NISTER RESPIRATION (MOUTH-TO-MOUTH) OR OXYGEN AS
INDICATED. CALL A PHYSICIAN. INGESTION: SEEK MEDICAL ADVICE.
