1. IDENTIFICATION

-------------------------------------------------------------------------------------------------------------------------------------------------CHEMICAL NAME:   SILICON DIOXIDE

-------------------------------------------------------------------------------------------------------------------------------------------------2. HAZARDS INFORMATION

-------------------------------------------------------------------------------------------------------------------------------------------------EMERGENCY OVERVIEW   REMOVE VICTIM TO FRESH AIR, KEEP WARM AND QUIET, GIVE OXYGEN IF

BREATHING IS DIFFICULT AND SEEK MEDICAL ATTENTION IF SYMPTOMS

PERSIST.

POTENTIAL HEALTH EFFECTS     SILICA  IS  THE  CHIEF  CAUSE  OF  PULMONARY  DUST  DISEASE.  THE

PROLONGED  INHALATION  OF  DUSTS  CONTAINING  FREE  SILICA  MAY

RESULT IN THE DEVELOPMENT OF DISABLING, PULMONARY FIBROSIS

KNOWN AS SILICOSIS. THE ACTION OF CRYSTALLINE SILICA ON THE

LUNGS RESULTS IN THE PRODUCTION OF A DIFFUSE, NODULAR FIBROSIS

IN  WHICH  THE  PARENCHYMA  AND  THE  LYMPHATIC  SYSTEMS  ARE

INVOLVED. THIS FIBROSIS IS, TO A CERTAIN EXTENT, PROGRESSIVE, AND

MAY CONTINUE TO INCREASE FOR SEVERAL YEARS AFTER EXPOSURE IS

TERMINATED. THE FIRST AND MOST COMMON SYMPTOM IS SHORTNESS

OF BREATH. FURTHER PROGRESS OF THE DISEASE RESULTS IN MARKED

FATIGUE,  EXTREME  DYSPNEA  AND  CYANOSIS,  LOSS  OF  APPETITE,

PLEURITIC PAIN AND TOTAL INCAPACITY TO WORK. IF TUBERCULOSIS

DOES NOT SUPERVENE, THE CONDITION MAY EVENTUALLY CAUSE DEATH

EITHER  FROM  CARDIAC  FAILURE  OR  FROM  DESTRUCTION  OF  LUNG

TISSUE, WITH RESULTANT ANOXEMIA.

EYE:     MAY CAUSE EYE IRRITATION.

SKIN:    MAY CAUSE SKIN IRRITATION.

INGESTION:     MAY CAUSE IRRITATION OF THE DIGESTIVE TRACT. THE TOXICOLOGICAL

PROPERTIES OF THIS SUBSTANCE HAVE NOT BEEN FULLY INVESTIGATED.

INHALATION:   SILICON DIOXIDE 0-100 10 MG/M 3 /% RESPIRABLE SIO 2+2 .1 MG/M 3 RES

CHRONIC: NOT AVAILABLE.

 

-------------------------------------------------------------------------------------------------------------------------------------------------3. FIRST AID

-------------------------------------------------------------------------------------------------------------------------------------------------EYES: FLUSH  EYES  WITH  PLENTY  OF  WATER  FOR  AT  LEAST  15  MINUTES,

 

OCCASIONALLY LIFTING THE UPPER AND LOWER LIDS. GET MEDICAL AID.

 

SKIN:    GET MEDICAL AID IF IRRITATION DEVELOPS OR PERSISTS. RINSE AREA

 

WITH LARGE AMOUNTS OF WATER FOR AT EAST 15 MINUTES.

INHALATION:   REMOVE FROM EXPOSURE TO FRESH AIR IMMEDIATELY. GET MEDICAL

AID IF COUGH OR OTHER SYMPTOMS APPEAR.

INGESTION:     GIVE 1-2 GLASSES OF MILK OR WATER AND INDUCE VOMITING, SEEK

MEDICAL ATTENTION IF SYMPTOMS PERSIST. NEVER INDUCE VOMITING

OR GIVE ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON. NOTES TO

PHYSICIAN: TREAT SYMPTOMATICALLY AND SUPPORTIVELY.

 

-------------------------------------------------------------------------------------------------------------------------------------------------

4. FIRE FIGHTING MEASURES

-------------------------------------------------------------------------------------------------------------------------------------------------GENERAL INFORMATION:      WEAR A SELF-CONTAINED BREATHING APPARATUS IN PRESSURE-

       DEMAND, MSHA/NIOSH (APPROVED OR EQUIVALENT), AND FULL     

       PROTECTIVE GEAR.

-------------------------------------------------------------------------------------------------------------------------------------------------5. HANDLING AND STORAGE

-------------------------------------------------------------------------------------------------------------------------------------------------HANDLING:     USE WITH ADEQUATE VENTILATION. MINIMIZE DUST GENERATION AND

       ACCUMULATION. 

       AVOID BREATHING DUST, VAPOR, MIST, OR GAS. AVOID CONTACT WITH      

       EYES, SKIN, AND CLOTHING.      

STORAGE: AVOID INGESTION AND INHALATION.     

       STORE IN A TIGHTLY CLOSED CONTAINER. STORE IN A COOL, DRY, WELL-  

       VENTILATED AREA AWAY FROM INCOMPATIBLE SUBSTANCES.  

 

-------------------------------------------------------------------------------------------------------------------------------------------------

6. EXPOSURE CONTROL AND PERSONAL PROTECTION

-------------------------------------------------------------------------------------------------------------------------------------------------ENGINEERING CONTROLS:  USE ADEQUATE VENTILATION TO KEEP AIRBORNE CONCENTRATIONS

LOW.

EXPOSURE LIMITS:

EYES:  FLUSH EYES WITH LUKEWARM WATER, LIFTING UPPER AND LOWER

EYELIDS, FOR AT LEAST 15 MINUTES. SEEK MEDICAL ATTENTION IF

SYMPTOMS PERSIST.

SKIN:    REMOVE CONTAMINATED CLOTHING, BRUSH MATERIAL OFF SKIN, WASH

AFFECTED AREA WITH MILD SOAP AND WATER, AND SEEK MEDICAL

ATTENTION  IF  SYMPTOMS  PERSIST.  CLOTHING  WEAR  APPROPRIATE

PROTECTIVE  CLOTHING  TO  PREVENT  SKIN  EXPOSURE.  RESPIRATORS:

FOLLOW THE OSHA RESPIRATOR REGULATIONS FOUND IN 29CFR 1910.13

FOR EUROPEAN STANDARD EN 149. ALWAYS USE A NIOSH OR EUROPEAN

STANDARD EN 149 APPROVED RESPIRATOR WHEN NECESSARY.
