Health Hazards Acute And Chronic: ACUTE:SILICIC ACID:ACUTE:EXPOS TO HIGH CONCS
MAY CAUSE PHYSICAL DISCOMFORT OF UPPER RESP TRACT. CHRONIC:PULM EFTS OF
LONGTERM EXPOS MAY VARY W/FORM OF AMORPHOUS SILICA &, MORE IMPORTANTLY,
DEGREE OF CONTAM W/CRYSTALLINE FORM OF SILICA. STUD IES DONE ON GROUP OF
WORKERS EXPOS TO PRECIPITATED SILICA DUST (EFTS OF OVEREXP)
Explanation of Carcinogenicity: NOT RELEVANT.
Signs and Symptoms of Overexposure: HLTH HAZ:FOR AVERAGE IF 8.6 YRS, REVEALED
NO ADVERSE EFTS ON PULM FUNC TESTS/CHEST X-RAYS. IT IS POSS HOWEVER, X-RAY
CHANGES IN LUNGS, W/ONLY EXERTIONAL DYSPNEA/W/OUT ANY DISABILITY, MAY OCCUR IN
SOME WORKERS, IF QTY OF DUST TO WHICH THEY A RE EXPOS IS GREAT ENOUGH. PRESENCE
OF CRYSTALLINE SILICA MAY GREATLY (SUPDAT)
Medical Conditions Aggravated by Overexposure: NONE SPECIFIED BY MANUFACTURER.

FIRST AID
==============================================================================
INHAL:REMOVE TO FRESH AIR IMMED. IF BRTHG HAS STOPPED, PERFORM ARTF RESP. KEEP
PERSON WARM & @ REST. TREAT SYMPTOMATICALLY & SUPPORTIVELY. GET MED
ATTN IMMED. SKIN:REMOVE CONTAMD CLTHG & SHOES IMMED. WASH AFFECTED AREA
W/SOAP/MILD DETERGENT & LG AMTS OF WATER UNTIL NO EVID OF CHEM REMAINS
(APPROX 15-20 MINS). GET MED ATTN. EYE:WASH IMMED W/LG AMTS OF WATER/NORMAL
SALINE, OCCASNLY LIFTING(ING 12)
