IV.   FIRE AND EXPLOSION HAZARDS DATA

Flash Point:  N/A

Autoignition Temperature:  N/A

Explosive Limits:  Lower:  N/A         Upper:  N/A

Extinguishing Media:  Use suitable extinguishing media for surrounding materials and type of fire.

Special Firefighting Procedures:  Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes.  Fumes from fire are hazardous.  Isolate runoff to prevent environmental contamination.

Unusual Fire and Explosion Hazards:  When heated to decomposition, vanadium oxide may emit toxic fumes of vanadium oxides.  Reacts slowly to form vanadium pentoxide.

V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

To the best of our knowledge the chemical, physical and toxicological properties of vanadium oxide have not been thoroughly investigated and reported.

Vanadium compounds act chiefly as an irritant to the eyes and respiratory tract.  Exposure may cause conjunctivitis, rhinitis and reversible bronchitis, bronchospasms and asthma like disease.  May cause polycythemia, red blood cell destruction and anemia, albuminuria and hematuria, gastrointestinal disorders, nervous complaints and severe cough.

Acute Effects:

Inhalation:  May cause irritation of the respiratory tract, chest tightness, wheezing, and coughing.

Ingestion:  May cause abdominal discomfort, nausea, vomiting, cramping.  May cause harmless green tongue discoloration.

Skin:  May cause irritation.

Eye: May cause irritation.

Chronic Effects:

Inhalation:  Vanadium compounds may cause pneumonia and other pathologic symptoms (chronic symptoms of vanadium toxicity).

Ingestion:  No chronic health effects recorded.

Skin:  May cause dermatitis.  Absorption of harmful amounts possible.

Eye:  May cause conjunctivitis.

Target Organs:  May affect the kidneys, respiratory system, skin and eyes.

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

Carcinogenicity:  NTP:  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:  If conscious, give at least two glasses of water, induce vomiting and call a physician.  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 and water.  See a physician if irritation occurs.

EYE:  Flush with copious amounts of water for 10-20 minutes to make sure no particles remain in the eye.  See a physician if irritation occurs.

VI.   REACTIVITY DATA

Stability:  Stable.

Conditions to Avoid:  Moisture, heat.

Incompatibility (Materials to Avoid):  Aluminum powder, moisture.

Hazardous Decomposition Products:  Reacts slowly with air to form V₂O₄ (blue).  Reacts with moisture to form V₆O₁₃ (green).  Reacts slowly at 120^oC to form V₂O₅ (yellow).

Hazardous Polymerization:  Will not occur.

VII.   SPILL OR LEAK PROCEDURES

Steps to Be Taken in Case Material Is Released or Spilled:  Wear appropriate respiratory and protective equipment specified in section VIII.  Isolate spill and provide ventilation.  Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal.  Take care not to raise dust.  Prevent from entering sewage or surface water.

Waste Disposal Method:  Dispose of in accordance with Federal, State and Local regulations.  Do not use procedures that generate dust.

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection:  Use NIOSH/MSHA-approved respirators in dusty areas.

Ventilation:  Local exhaust ventilation may be necessary to control any air contaminants to within their PELs or TLVs during the use of this product.  General exhaust is not recommended.

Protective Gloves:  Rubber gloves

Eye Protection:  Wear dust-resistant safety glasses with side-shields.  Facilities to flush the eyes with water should be readily available.

Other Protective Clothing and Equipment:  Protective gear suitable to prevent contamination.

IX.   SPECIAL PRECAUTIONS

Other Handling and Storage Conditions:  Keep material dry and in tightly closed containers.  Personnel should clean up after handling the product and avoid areas where fume or dust is present.

Other Precautions:  Vanadium oxide reacts slowly in moisture to form vanadium pentoxide.  Handle and store in a controlled, dry environment.

Work Practices:  Implement engineering and work practice controls tor educe and maintain concentration of exposure at low levels.  Use good housekeeping and sanitation practices.  Do not use tobacco or food in work area.  Wash thoroughly before eating or smoking.  Don not blow dust off clothing or skin with compressed air.  Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
