Health Hazards Acute and Chronic:SILICIN DIOXIDE - ACUTE: EXCESSIVE
CONTACT WITH POWDER CAN CAUSE DRYING OF MUCOUS MEMBRANES OF THE
NOSE, EYES, AND THROAT DUE TO ABSORPTION OF MOISTURE AND OILS. THIS
MATERIAL CAN CAUSE NASAL IRRITATI ON AND NOSEBLEEDS. EYE CONTACT
WITH POWDER CAN RESULT IN MILD IRRITATION. CHRONIC: AN
EPIDEMIOLOGICAL STUDY WAS CONDUCTED WHICH INCLUDED 165 PRECIPITATED
SILICA WORKERSWHO HAD BEEN EXPOSED AN AVERAGE TIME SPAN OF 8.6
YEARS. OF THESE 165 WORKERS, 44 HAD BEEN EXPOSED FOR AN AVERAGE OF
18 YEARS. NO ADVERSE EFFECTS WERE NOTED IN COMPLETE MEDICAL
EXAMINATION (INCLUDING CHEST ROENTGENOGRAMS) OF THE WORK ERS.
PULMONARY FUNCTION (OTHER INFO)
Explanation of Carcinogenicity:NONE
Effects of Overexposure:EYES-SIL DIOXIDE: MILDLY IRRITATING. PET
PROCESS OIL: CONTACT MAY CAUSE EYE IRRIT. SKIN-SIL DIOXIDE: MILDLY
IRRITATING. PET PROCESS OIL: PROLONGED OR REPEATED SKIN CONT TENDS
TO REMOVE SKIN OILS POSS IBLY LEADING TO IRRIT & DERMATITIS. THIS
PROD IS JUDGED TO BE NEITHER A CORROSIVE NOR AN IRRITANT BY OSHA
CRITERIA. INHAL-SIL DIOXIDE: NUISANCE DUST. PET PROCESS OIL: PROD
HAS A LOW ORDER OF ACUTE OR AL & DERMAL TOXICITY, BUT MINUTE
AMOUNTS ASPIRATED INTO THE LUNG DURING INGEST OR VOMITING MAY CAUSE
MILD TO SEVERE PULMONARY INJURY AND POSSIBLY DEATH. INGEST-SIL
DIOXIDE: NOT SIGNIFICANTLY TOXIC. P ET PROCESS OIL: SEE INHALATION.
Medical Cond Aggravated by Exposure:SIL DIOXIDE: PERSONS W/ BREATHING
PROBLEMS / LUNG DISEASES SHOULD NOT WORK IN DUSTY AREAS UNLESS A
PHYSICIAN APPROVES & CERTIFIES THEIR FITNESS TO WEAR RESP
PROTECTION. PET PROCESS OILS: NONE RECOGNIZED

First Aid:EYE: IMMED RINSE W/ CLEAN WATER FOR 15 MIN. RETRACT EYELIDS
OFTEN. IF IRRIT PERSISTS, SEEK MED ATTEN. SKIN: IMMED REMOVE
CONTAM CLOTHING. WASH SKIN THOROUGHLY W/ MILD SOAP & WATER. FLUSH
W/ LUKEWARM WATER FOR 15 MIN. SEEK MED ATTEN IF ILL EFFECT OR
IRRIT DEVELOPS. INHAL: VAPOR PRESS IS VERY LOW. VAPOR INHAL UNDER
AMBIENT CONDITIONS IS NORM NOT A PROBLEM. IF OVERCOME BY VAPOR FROM
HOT PROD, IMMED REMOVE FROM EXP & CALL A MD. IF BREATHING IS IRREG
OR HAS STOPPED, START RESUSCITATION; ADMIN OXYGEN, IF AVAIL. IF
OVEREXP TO OIL MIST, REMOVE FROM FURTHER EXP. INGESTION: IF
INGESTED, DO NOT INDUCE VOMITING, CALL A MD IMMEDIATELY.
