5. Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, carbon dioxide, water spray, foam.
Unsuitable Extinguishing Media: High-pressure water jets may spread material.
Special Hazards: Decomposition at high temperature releases toxic fumes such as carbon monoxide, carbon dioxide, oxides of vanadium.
Protective Equipment: Firefighters use self-contained breathing apparatus and full protective clothing.
Additional Information: Prevent runoff from entering water systems. Cool containers exposed to fire with water spray.

6. Accidental Release Measures

Personal Precautions: Avoid dust formation, wear suitable respiratory protection and gloves.
Environmental Precautions: Prevent material from entering drains or watercourses. Small spills: Sweep or vacuum, using equipment designed to avoid dust generation. Large spills: Stop source of release, dike area for containment.
Cleanup Methods: Sweep up or collect spilled material, place in suitable closed containers for disposal. Clean contaminated area with soap and water.
Decontamination: Ensure proper ventilation, dispose of collected material as hazardous waste.

7. Handling and Storage

Handling: Work in a well-ventilated area, avoid inhaling dust or contact with skin and eyes. Do not eat, drink or smoke during use. Wear gloves and protective clothing.
Storage Conditions: Store in tightly sealed original containers in a dry, cool, well-ventilated area. Store away from food, acids, combustibles, and incompatible materials.
Incompatibles: Strong oxidizers, strong acids, reducing agents, alkalis.
Other Notes: Label containers properly. Limit access to trained personnel.

8. Exposure Controls and Personal Protection

Occupational Exposure Limits: OSHA PEL (none established for compound), ACGIH TLV for vanadium compounds: 0.05 mg/m³ (as V, respiratory fraction)
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended limits.
Personal Protective Equipment: Safety goggles, gloves (nitrile or neoprene recommended), laboratory coats, approved dust respirator if ventilation is inadequate.
Hygiene Measures: Wash hands and face after handling, shower and change clothing at end of shift. Do not touch face or rub eyes during use.

Other Changes: Prolonged exposure to heat or moisture may lead to decomposition and release of toxic vapors.

11. Toxicological Information

Likely Routes of Exposure: Ingestion, inhalation, skin and eye contact
Acute Effects: Nausea, vomiting, abdominal pain, respiratory tract irritation, coughing, skin and eye irritation
Chronic Effects: Exposure to vanadium compounds linked to nervous system symptoms, bronchitis, pulmonary edema, anemia with prolonged or repeated exposure
Toxicity Data: LD50 (oral, rat): not available for this specific compound; for vanadium compounds, typically in the range 10–100 mg/kg
Carcinogenicity: Not classifiable by IARC; no evidence of carcinogenicity in humans at expected exposure levels, but vanadium compounds under review for possible long-term effects
Mutagenicity: No specific data for vanadium oxalate; some vanadium compounds show mutagenic activity in vitro
Other Health Hazards: May interfere with enzyme function; individuals with kidney issues should avoid exposure.

12. Ecological Information

Ecotoxicity: Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment
Mobility: Slightly soluble, may persist in soils and sediments
Biodegradability: Vanadium does not degrade, accumulates in environment; oxalate breaks down under aerobic conditions
Bioaccumulation: Potential to bioaccumulate in aquatic plants and animals
Other Environmental Hazards: Avoid release to waterways, storm drains, and natural environments.

13. Disposal Considerations

Product Disposal: Collect and contain in suitable closed, labeled containers; dispose of in accordance with local, regional, and national hazardous waste regulations
