First Aid Measures

Ingestion

Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.

Inhalation

Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. DO NOT use mouth-to-mouth respiration.

Skin

Get medical aid immediately. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.

Eyes

Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.

Handling and Storage

Storage

Store in a cool, dry, well-ventilated area away from incompatible substances. Keep containers tightly closed.

Handling

Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Do not get on skin or in eyes. Do not ingest or inhale. Discard contaminated shoes.

Hazards Identification

Inhalation

May cause liver and kidney damage. May cause irritation of the respiratory tract with burning pain in the nose and throat, coughing, wheezing, shortness of breath and pulmonary edema.

Skin

Contact with skin causes irritation and possible burns, especially if the skin is wet or moist. Contact with the skin may cause skin lesions which are characterized by cracking and fissuring of the skin and the development of slow-healing ulcers.

Eyes

May cause eye irritation and possible damage.

Ingestion

May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns. May cause liver and kidney damage. May cause central nervous system effects and/or neurological effects. May cause greenish-black tongue discoloration due to deposition of vanadium salts. Ingestion of large amounts may cause an increase in blood pressure.

Hazards

Containers may explode when heated. Runoff may pollute waterways.

Exposure Controls/Personal Protection

Personal Protection

Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.

Respirators

A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.

Exposure Effects

Chronic inhalation may cause effects similar to those of acute inhalation. May cause liver and kidney damage. May produce scattered allergy-like eczematous skin lesions symptomatic of vanadium toxicity.

Exposure limit(s)

NIOSH REL: C 0.05 mg V/m3 15-min. Note: REL applies to all V cmpds except V metal and Vanadium carbide). {Vanadium fume}}NIOSH REL: C 0.05 mg V/m3 15-minute NIOSH IDLH: 35 mg/m3 (as V) {{V fume}} 35 mg/m3 (as V)

Fire Fighting Measures

Fire Fighting

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use extinguishing media appropriate to the surrounding fire. Substance is noncombustible. Extinguishing media: Substance is noncombustible; use agent most appropriate to extinguish surrounding fire.

Fire Potential

Nonflammable.

Accidental Release Measures

Small spills/leaks

Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation.

Stability and Reactivity

Stability

Stable at room temperature in closed containers under normal storage and handling conditions.

Incompatibilities

Strong oxidizing agents.

Decomposition

Sulfur oxides (SOx), including sulfur oxide and sulfur dioxide, vanadium oxide (VOx) gases.

Combustion Products

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
