CRYSTALLINE SILICA (QUARTZ) IS HEATED TO MORE THAN 1470 DEG. C, QUARTZ CAN
CHANGE TO A FORM OF CRYSTALLINE SILICA KNOWN AS CRISTOBALITE. THE OSHA PEL
FOR CRYSTALLINE SILICA AS TRIDYMITE OR CRISTOBALITE IS ONE-HALF OF THE OSHA
PEL FOR CRYSTALLINE SILICA (QUARTZ).
APPROPRIATE ENGINEERING CONTROLS:
USE ADEQUATE GENERAL OR LOCAL EXHAUST VENTILATION TO MAINTAIN
CONCENTRATIONS IN THE WORKPLACE BELOW THE APPLICABLE EXPOSURE LIMITS LISTED
ABOVE.
RESPIRATORY PROTECTION:
IF IT IS NOT POSSIBLE TO REDUCE AIRBORNE EXPOSURE LEVELS TO BELOW THE OSHA
PEL OR OTHER APPLICABLE LIMIT WITH VENTILATION, USE THE TABLE BELOW TO
ASSIST YOU IN SELECTING RESPIRATORS THAT WILL REDUCE PERSONAL EXPOSURES TO
BELOW THE OSHA PEL. THIS TABLE IS PART OF THE NIOSH RESPIRATOR SELECTION
LOGIC, 2004, CHAPTER III, TABLE 1, "PARTICULATE RESPIRATORS". THE FULL
DOCUMENT CAN BE FOUND AT WWW.CDC.GOV/NIOSH/NPPTL/TOPICS/RESPIRATORS; THE
USER OF THIS MSDS IS DIRECTED TO THAT SITE FOR INFORMATION CONCERNING
RESPIRATOR SELECTION AND USE. THE ASSIGNED PROTECTION FACTOR (APF) IS THE
MAXIMUM ANTICIPATED LEVEL OF PROTECTION PROVIDED BY EACH TYPE OF RESPIRATOR
WORN IN ACCORDANCE WITH AN ADEQUATE RESPIRATORY PROTECTION PROGRAM. FOR
EXAMPLE, AN APF OF 10 MEANS THAT THE RESPIRATOR SHOULD REDUCE THE AIRBORNE
CONCENTRATION OF A PARTICULATE BY A FACTOR OF 10, SO THAT IF THE WORKPLACE
CONCENTRATION OF A PARTICULATE WAS 150 UG/M3, THEN A RESPIRATOR WITH AN APF
OF 10 SHOULD REDUCE THE CONCENTRATION OF PARTICULATE TO 15 UG/M3. IN USING
CHEMICAL CARTRIDGES, CONSIDERATION MUST BE GIVEN TO SELECTION OF THE
CORRECT CARTRIDGE FOR THE CHEMICAL EXPOSURE AND THE MAXIMUM USE
CONCENTRATION FOR THE CARTRIDGE. IN ADDITIONAL A CARTRIDGE CHANGE-OUT
SCHEDULE MUST BE DEVELOPED BASED ON THE CONCENTRATIONS IN THE WORKPLACE.

| 11. TOXICOLOGICAL INFORMATION | |
ACUTE EFFECTS OF EXPOSURE:
INHALATION:
INHALATION OF DUST MAY CAUSE RESPIRATORY TRACT IRRITATION. SYMPTOMS OF
EXPOSURE MAY INCLUDE COUGH, SORE THROAT, NASAL CONGESTION, SNEEZING,
WHEEZING AND SHORTNESS OF BREATH.
INGESTION:
INGESTION IN AN UNLIKELY ROUTE OF EXPOSURE. IF DUST IS SWALLOWED, IT MAY
IRRITATE THE MOUTH AND THROAT.
SKIN CONTACT: NO ADVERSE EFFECTS ARE EXPECTED.
EYE CONTACT: PARTICULATES MAY CAUSE ABRASIVE INJURY.
CHRONIC EFFECTS:
PROLONGED INHALATION OF RESPIRABLE CRYSTALLINE SILICA MAY CAUSE LUNG
DISEASE, SILICOSIS, LUNG CANCER AND OTHER EFFECTS AS INDICATED BELOW. THE
METHOD OF EXPOSURE THAT CAN LEAD TO THE ADVERSE HEALTH EFFECTS DESCRIBED
BELOW IS INHALATION.
A. SILICOSIS
SILICOSIS CAN EXIST IN SEVERAL FORMS, CHRONIC (OR ORDINARY), ACCELERATED,
OR ACUTE:
CHRONIC OR ORDINARY SILICOSIS IS THE MOST COMMON FORM OF SILICOSIS, AND CAN
OCCUR AFTER MANY YEARS (10 TO 20 OR MORE) OF PROLONGED REPEATED INHALATION
OF RELATIVELY LOW LEVELS OF AIRBORNE RESPIRABLE CRYSTALLINE SILICA DUST. IT
IS FURTHER DEFINED AS EITHER SIMPLE OR COMPLICATED SILICOSIS. SIMPLE
SILICOSIS IS CHARACTERIZED BY LUNG LESIONS (SHOWN AS RADIOGRAPHIC
OPACITIES) LESS THAN 1 CENTIMETER IN DIAMETER, PRIMARILY IN THE UPPER LUNG
ZONES. OFTEN, SIMPLE SILICOSIS IS NOT ASSOCIATED WITH SYMPTOMS, DETECTABLE
CHANGES IN LUNG FUNCTION OR DISABILITY. SIMPLE SILICOSIS MAY BE PROGRESSIVE
AND MAY DEVELOP INTO COMPLICATED SILICOSIS OR PROGRESSIVE MASSIVE FIBROSIS
(PMF). COMPLICATED SILICOSIS OR PMF IS CHARACTERIZED BY LUNG LESIONS (SHOWN
AS RADIOGRAPHIC OPACITIES) GREATER THAN 1 CENTIMETER IN DIAMETER.
COMPLICATED SILICOSIS OR PMF SYMPTOMS, IF PRESENT, ARE SHORTNESS OF BREATH
AND COUGH. COMPLICATED SILICOSIS OR PMF MAY BE ASSOCIATED WITH DECREASED
LUNG FUNCTION AND MAY BE DISABLING. ADVANCED COMPLICATED SILICOSIS OR PMF
MAY LEAD TO DEATH. ADVANCED COMPLICATED SILICOSIS OR PMF CAN RESULT IN
HEART DISEASE SECONDARY TO THE LUNG DISEASE (COR PUMONALE).
ACCELERATED SILICOSIS CAN OCCUR WITH PROLONGED REPEATED INHALATION OF HIGH
CONCENTRATIONS OF RESPIRABLE CRYSTALLINE SILICA OVER A RELATIVELY SHORT
PERIOD; THE LUNG LESIONS CAN APPEAR WITHIN FIVE (5) YEARS OF INITIAL
EXPOSURE. PROGRESSION CAN BE RAPID. ACCELERATED SILICOSIS IS SIMILAR TO
CHRONIC OR ORDINARY SILICOSIS, EXCEPT THAT LUNG LESIONS APPEAR EARLIER AND
PROGRESSION IS MORE RAPID.
ACUTE SILICOSIS CAN OCCUR AFTER THE REPEATED INHALATION OF VERY HIGH
CONCENTRATIONS OF RESPIRABLE CRYSTALLINE SILICA OVER A SHORT TIME PERIOD,
SOMETIMES AS SHORT AS A FEW MONTHS. THE SYMPTOMS OF ACUTE SILICOSIS INCLUDE
PROGRESSIVE SHORTNESS OF BREATH, FEVER, COUGH, WEAKNESS AND WEIGHT LOSS.
ACUTE SILICOSIS IS FATAL.
B. CANCER:
IARC - THE INTERNATIONAL AGENCY FOR RESEARCH ON CANCER ("IARC") CONCLUDED
THAT "CRYSTALLINE SILICA IN THE FORM OF QUARTZ OR CRISTOBALITE DUST IS
CARCINOGENIC TO HUMANS (GROUP 1)". FOR FURTHER INFORMATION ON THE IARC
EVALUATION, SEE IARC MONOGRAPHS ON THE EVALUATION OF CARCINOGENIC RISKS TO
HUMANS, VOLUME 100C,"A REVIEW OF HUMAN CARCINOGENS: ARSENIC, METALS, FIBRES
AND DUSTS " (2011).
NTP CLASSIFIES "SILICA, CRYSTALLINE (RESPIRABLE SIZE)" AS KNOWN TO BE A
HUMAN CARCINOGEN.
C. AUTOIMMUNE DISEASES:
SEVERAL STUDIES HAVE REPORTED EXCESS CASES OF SEVERAL AUTOIMMUNE DISORDERS
- SCLERODERMA, SYSTEMIC LUPUS ERYTHEMATOSUS, RHEUMATOID ARTHRITIS - AMONG
SILICA-EXPOSED WORKERS.
D. TUBERCULOSIS:
INDIVIDUALS WITH SILICOSIS ARE AT INCREASED RISK TO DEVELOP PULMONARY
TUBERCULOSIS, IF EXPOSED TO TUBERCULOSIS BACTERIA. INDIVIDUALS WITH CHRONIC
SILICOSIS HAVE A THREE-FOLD HIGHER RISK OF CONTRACTING TUBERCULOSIS THAN
SIMILAR INDIVIDUALS WITHOUT SILICOSIS.
E. KIDNEY DISEASE:
SEVERAL STUDIES HAVE REPORTED EXCESS CASES OF KIDNEY DISEASES, INCLUDING
END STAGE RENAL DISEASE, AMONG SILICA-EXPOSED WORKERS. FOR ADDITIONAL
INFORMATION ON THE SUBJECT, THE FOLLOWING MAY BE CONSULTED: "KIDNEY DISEASE
AND SILICOSIS", NEPHRON, VOLUME 85, PP. 14-19 (2000).
F. NON-MALIGNANT RESPIRATORY DISEASES:
THE READER IS REFERRED TO SECTION 3.5 OF THE NIOSH SPECIAL HAZARD REVIEW
CITED BELOW FOR INFORMATION CONCERNING THE ASSOCIATION BETWEEN EXPOSURE TO
CRYSTALLINE SILICA AND CHRONIC BRONCHITIS, EMPHYSEMA AND SMALL AIRWAYS
DISEASE. THERE ARE STUDIES THAT DISCLOSE AN ASSOCIATION BETWEEN DUSTS FOUND
IN VARIOUS MINING OCCUPATIONS AND NON-MALIGNANT RESPIRATORY DISEASES,
PARTICULARLY AMONG SMOKERS. IT IS UNCLEAR WHETHER THE OBSERVED ASSOCIATIONS
EXIST ONLY WITH UNDERLYING SILICOSIS, ONLY AMONG SMOKERS, OR RESULT FROM
EXPOSURE TO MINERAL DUSTS GENERALLY (INDEPENDENT OF THE PRESENCE OR ABSENCE
OF CRYSTALLINE SILICA, OR THE LEVEL OF CRYSTALLINE SILICA IN THE DUST).
SOURCES OF INFORMATION:
THE NIOSH HAZARD REVIEW - OCCUPATIONAL EFFECTS OF OCCUPATIONAL EXPOSURE TO
RESPIRABLE CRYSTALLINE SILICA PUBLISHED IN APRIL 2002 SUMMARIZES AND
DISCUSSES THE MEDICAL AND EPIDEMIOLOGICAL LITERATURE ON THE HEALTH RISKS
AND DISEASES ASSOCIATED WITH OCCUPATIONAL EXPOSURES TO RESPIRABLE
CRYSTALLINE SILICA. THE NIOSH HAZARD REVIEW IS AVAILABLE FROM NIOSH -
