Hazards and Protection.
Storage
Closed mild steel or glass containers.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Gas mask equipped with a filter approved by the us bureau of mines. Acid resistant gloves. Soft goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Use water spray to knock-down vapors. Do not use water on material itself. Neutralize spilled material with crushed limestone, soda ash, or lime.
Stability
Reactive only under extreme conditions, may react explosively with water.
Incompatibilities
Incompatible with bases, including amines, with strong oxidizing agents, and with alcohols May react vigorously or explosively

Fire.
Fire fighting
Use dry chemical, dry sand, or carbon dioxide. Do not use water on material itself. If large quantities of combustibles are involved, use water in flooding quantities as spray and fog. Use water spray to knock-down vapors. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Fire potential
Nonflammable. No fire hazard.
Hazards
Substance will react with water (some violently), releasing corrosiveand/or toxic gases.
Combustion products
Irritating fumes of hydrogen chloride may form in fires.

Exposure effects
   Ingestion
Abdominal cramping, diarrhea, black stools, and green tongue developed in volunteers given ammonium vanadyl tartrate.
   Inhalation
Pulmonary irritation leading to pulmonary edema is a possible effect with high concentrations. Occupational asthma has been reported.
   Skin
Dermatitis, and green discoloration of the skin, may be seen with exposure to vanadium compounds.
   Eyes
See Inhalation.

First aid
 
   Ingestion
Seek medical assistance.
   Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device.Administer oxygen if breathing is difficult.
   Skin
Wipe exposed areas free of the chemical with a dry cloth, then flush thoroughly with water.
   Eyes
Flush with water for 15 min.
