V.   HEALTH HAZARD INFORMATION

To the best of our knowledge the chemical, physical and toxicological properties of niobium pentoxide have not been thoroughly investigated and recorded.

Niobium compounds have caused liver damage in animal studies.  Niobium metal has caused kidney damage in experimental animals and fibrogenic effects on the lungs of experimental animals.

Acute Effects:

Inhalation:  May cause irritation to the nose and throat.

Ingestion:  No acute health effects recorded.

Skin:  May cause irritation.

Eye:  May cause irritation.

Chronic Effects:

Inhalation:  May cause kidney damage and fibrogenic effects on the lungs.

Ingestion:  No chronic health effects recorded.

Skin:  No chronic health effects recorded.

Eye:  No chronic health effects recorded.

Target Organs:  May affect the kidneys and lungs.

Medical Conditions Generally Aggravated by Exposure:  Pre-existing respiratory disorders.

CarcinogenicityNTP:  No         IARC:  No        OSHA:  No

 

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult and seek medical attention.

INGESTION:  Give 1-2 glasses of milk or water and induce vomiting, seek medical attention.  Never induce vomiting or give anything by mouth to an unconscious person. 

SKIN:  Remove contaminated clothing from affected area, brush material off skin, wash with soap or mild detergent and large amounts of water.  Seek medical attention, if needed.

EYES:  Flush eyes immediately with large amounts of water, lifting upper and lower lids.  Seek medical attention if symptoms persist.
