Health Hazards Acute and Chronic:EXPOS TO QTYS OF CRYSTALLINE SILICA
DUST IN EXCESS OF OSHA PEL/ACGIH TLV IS A KNOWN CAUSE OF SILICOSIS,
A PROGRESSIVE, SOMETIMES FATAL, LUNG DISEASE. MFR, IN CONJUNCTION
W/OTHER MEMBERS OF INTERNATION AL DIATOMITE PRODUCERS ASSOCIATION
(IDPA), HAS SPONSORED A STUDY TO EXAMINE LONG TERM HLTH EFTS AMONG
CERTAIN WORKERS IN DIATOMACEOUS EARTH (DE) INDUSTRY. STUDY WAS
CONDUCTED BY UNIVERSITY OF WASHINGT ON SCHOOL OF PUBLIC HLTH &
COMMUNITY MEDICINE & FINAL RPT WAS ISSUED IN OCTOBER, 1992. RPT
CONCLUDED THAT THERE WAS INCR IN NON-MALIGNANT RESP DISEASES (NMRD)
& LUNG CANCER INCIDENCE AMONG THOSE DE WO RKERS STUDIED WHEN (EFTS
OF OVEREXP)
Explanation of Carcinogenicity:SILICA, CRYSTALLINE-QUARTZ/CRISTOBALITE:
IARC MONOGRAPHS, VOLUME 68, 1998: GROUP 1. NTP 8TH ANNUAL REPORT ON
CARCINOGENS, 1998: REASONABLY ANTICIPATED TO BE HUMAN CARCINOGEN.
HUMAN: LUNG.
Effects of Overexposure:HLTH HAZ: COMPARED TO NATL & REGIONAL
POPULATIONS (STD MORTALITY RATIO OF 2.59 & 1.43, RESPECTIVELY). RPT
FURTHER CONCLUDED THAT RELATIVELY INTENSE EXPOS THAT OCCURRED
BEFORE THE 1950'S WERE PROBABLY THE MOST IMPORTANT CONTRIBUTORS TO
EXCESSES IN NMRD & LUNG CANCER. IN ADDN, DATA IN RPT INDICATED THAT
IMPROVEMENTS IN DUST CTL IN INDUSTRY APPEAR TO HAVE ABATED ANY
EXCESS RISK OF SILICOSIS & LUNG CA NCER IN TODAY'S WORK ENVIRON.
MFR INTENDS TO CONTINUE TO SUPPORT MEANINGFUL RESEARCH IN FUTURE
THRU IDPA. A SUMMARY RPT OF THE UNIVERSITY OF WASHINGTON STUDY IS
AVAIL ON REQUEST. (SUP DAT)
Medical Cond Aggravated by Exposure:PRE-EXISTING DISEASES OF THE UPPER
RESPIRATORY TRACT AND LUNG SUCH AS BRONCHITIS, EMPHYSEMA, AND
ASTHMA.

First Aid:SKIN: NOT ABSORBED BY THE SKIN. MAY CAUSE DRYNESS. USE
MOISTURE RENEWING LOTIONS IF DRYNESS OCCURS. EYES: MAY CAUSE
IRRITATION OR INFLAMMATION. WASH WITH GENEROUS QUANTITIES OF WATER
FOR AT LEAST 15 M INUTES. CONSULT PHYSICIAN IF IRRITATION PERSISTS.
INHALATION: ACUTE INHALATION CAN CAUSE DRYNESS OF THE NASAL
PASSAGES AND CONGESTION OF THE UPPER RESPIRATORY TRACT. REMOVE TO
FRESH AIR. INGESTION: SH ORT-TERM EXPOSURE NOT CONSIDERED HARMFUL.
DRINK GENEROUS AMOUNTS OF WATER TO REDUCE BULK AND DRYING EFFECTS.

Extinguishing Media:NON-FLAMMABLE. USE MEDIA SUITABLE FOR SURROUNDING
FIRE .
Fire Fighting Procedures:NOT APPLICABLE. WEAR NIOSH APPROVED
SELF-CONTAINED BREATHING APPARATUS AND FULL PROTECTIVE EQUIPMENT .

Handling and Storage Precautions:AVOID CREATING DUST. REPAIR OR
PROPERLY DISPOSE OF BROKEN BAGS. STORE IN A DRY PLACE TO MAINTAIN
PRODUCT QUALITY.
Other Precautions:FOR SAMPLING SILICA DUSTS REFER TO NIOSH ANALYTICAL
METHOD 7500 OR OSHA METHOD ID 142.

Respiratory Protection:NIOSH APPRVD RESPS FOR PROT AGAINST
PNEUMOCONIOSIS PRODUCING DUSTS REC WHEN DUST IS PRESENT. IF DUST
CONC IS LESS THAN 10 TIMES PEL, USE QUARTER/HALF MASK RESP
W/REPLACEMENT DUST FILTER/SINGLE USE DUS T RESP W/VALVE. IF DUST
CONC IS GREATER THAN 10 TIMES & LESS THAN 100 TIMES PEL, USE FULL
FACEPLATE RESP W/REPLACABLE DUST FILTER; (TOX INFO)
Ventilation:LOCAL: CONTROL WITHIN RECOMMENDED TLV/PEL. REFER TO ACGIH
PUBLICATION "INDUSTRIAL VENTILATION" OR SIMILAR PUBLICATIONS FOR
DESIGN OF VENTILATION SYSTEMS.
Protective Gloves:NOT NORMALLY NECESSARY. WEAR IMPERVIOUS GLOVES .

Other Protective Equipment:EYEWASH AND DELUGE SHOWER MEETING ANSI
DESIGN CRITERIA . PROTECTIVE FOOTWEAR NOT NECESSARY. PROTECTIVE
CLOTHING NOT NORMALLY NECESSARY.
Supplemental Safety and Health
EFTS OF OVEREXP: TARGET ORGANS: LUNGS. ACUTE: UPPER RESP IRRITANT. MAY
CAUSE COUGHING/THROAT IRRIT. CHRONIC: INHAL OF CRYSTALLINE SILICA
DUST IN EXCESS OF TLV REC BY ACGIH/IN EXCESS OF PEL ESTABLISHED BY
OSHA OVER EXTENDED NUMBER OF YRS MAY CAUSE SILICOSIS, A PROGRESSIVE
SOMETIMES FATAL LUNG DISEASE. (OTHER INFO)
