V.  HEALTH HAZARD INFORMATION

Effects of Exposure:

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

Vanadium pentoxide is poisonous by ingestion and inhalation as well as other routes.  Ingestion causes disturbances of the gastrointestinal tract.  May also causes a papular skin rash.  Vanadium pentoxide is a respiratory irritant.  Effects include skin pallor, greenish-black tongue, chest pain, cough, dsypnea, palpitation and lung changes.  Causes reproductive and mutagenic effects in laboratory animals.

Acute Effects:

Inhalation:  Poison.  Absorption by inhalation is nearly 100%.  Human systemic effects.  May cause irritation of the respiratory tract.  Vanadium compounds may cause nasal bleeding and acute bronchitis.  May cause vanadium toxicity.

Ingestion:  Poison.  Poison by ingestion, intraperitoneal, subcutaneous, intratracheal and intravenous routes.  May cause gastrointestinal disturbances. 

Skin:  May cause irritation and papular skin rash.

Eye:  May cause irritation.

Chronic Effects:

Inhalation:  May cause pneumonia and other pathologic symptoms.

Ingestion:  No chronic health effects recorded.

Skin:  May cause dermatitis.

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.  Seek medical attention immediately.

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

SKIN:  Remove contaminated clothing, brush material off skin, wash affected area with mild soap and water, seek medical attention if symptoms persist.

EYES:  Flush eyes with lukewarm water, lifting upper and lower eyelid, for at least 15 minutes.  Seek medical attention if symptoms persist.

VI.  REACTIVITY DATA

Stability:  Stable.

Conditions to Avoid:  Water/moisture

Incompatibility (Material to Avoid):  Mixtures with calcium + sulfur + water may ignite spontaneously.  ClF₃, lithium, peroxyformic acid.

Hazardous Decomposition Products:  Oxides of vanadium

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 area 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.

Waste Disposal Method:  Dispose of in accordance with all Federal, State and Local regulations.

VIII.  SPECIAL PROTECTION INFORMATION

Respiratory Protection:  NIOSH approved respirator

Ventilation:  Use local exhaust to maintain concentration of exposure below recommended levels.  General exhaust is recommended.

Protective Gloves:  Rubber

Eye Protection:  Safety glasses

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

IX.  SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage:  Store in a cool, dry area.  Store in a tightly sealed container.  Wash thoroughly after handling.  Do not store together with acids.

Other Precautions:  Keep containers closed as vanadium pentoxide will absorb some moisture from the air.

Work Practices:  Implement engineering and work practice controls to reduce 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 and smoking.  Do not blow dust off clothing or skin with compressed air.  Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
