5. HEALTH HAZARD INFORMATION

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

ROUTES OF ENTRY:   INHALATION, SKIN, EYES, AND INGESTION.

HEALTH HAZ. (ACUTE & CHRONIC):  TO THE BEST OF OUR KNOWLEDGE THE CHEMICAL,   

       PHYSICAL & TOXICOLOGICAL PROPERTIES OF TUNGSTEN    

       METAL HAVE NOT BEEN THOROUGHLY INVESTIGATED AND  

       RECORDED.   

TUNGSTEN COMPOUNDS:     INDUSTRIALLY, THIS ELEMENT DOES NOT CONSTITUTE AN   

       IMPORTANT HEALTH HAZARD. EXPOSURE IS RELATED    

       CHIEFLY TO THE DUST ARISING FROM THE CRUSHING AND  

       MILLING OF THE TWO CHIEF ORES OF TUNGSTEN, NAMELY   

       SCHEELITE AND WOLFRAMITE. LARGE OVERDOSES CAUSE 

       CENTRAL NERVOUS SYSTEM DISTURBANCES, DIARRHEA,   

       RESPIRATORY FAILURE AND DEATH IN EXPERIMENTAL  

       ANIMALS (SAX, DANGEROUS PROPERTIES OF INDUSTRIAL   

       MATERIALS, EIGHTH EDITION).   

INHALATION:         

ACUTE:      MAY CAUSE IRRITATION TO THE RESPIRATORY TRACT.   

CHRONIC: NO CHRONIC HEALTH EFFECTS RECORDED.  

INGESTION:           

ACUTE:      MODERATELY TOXIC BY INGESTION      

CHRONIC: LARGE OVERDOSES MAY CAUSE NERVOUS SYSTEM

SKIN:    DISTURBANCES, AND DIARRHEA.   

             

ACUTE:      MAY CAUSE ABRASIVE IRRITATION

CHRONIC: NO CHRONIC HEALTH EFFECTS RECORDED.  

EYE:           

ACUTE:      MAY CAUSE ABRASIVE IRRITATION.      

CHRONIC: NO CHRONIC HEALTH EFFECTS RECORDED.  

TARGET ORGANS:       MAY AFFECT THE RESPIRATORY AND CENTRAL NERVOUS   

       SYSTEMS. MEDICAL CONDITIONS GENERALLY      

       AGGRAVATED BY EXPOSURE: PRE-EXISTING RESPIRATORY

CARCINOGENICITY:    DISORDERS.  

             

NTP:     YES     

IARC MONOGRAPHS: YES

       AND SHORTNESS OF BREATH.  

INGESTION:     MAY CAUSE DIARRHEA  

SKIN:    MAY CAUSE REDNESS AND ITCHING.   

EYE:     MAY CAUSE REDNESS, ITCHING AND WATERING. 

 

EMERG. & FIRST AID PROCEDURES:            

INHALATION:   REMOVE VICTIM TO FRESH AIR, KEEP WARM AND QUIET,

       GIVE OXYGEN IF BREATHING IS DIFFICULT AND SEEK      

       MEDICAL ATTENTION IF SYMPTOMS PERSIST. 

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.
