Name: Sodium Orthovanadate
Chemical Formula: Na3VO4
CAS Number: 13721-39-6
Common Appearance: White or colorless powder
Odor: No distinguishable smell
Solubility: Readily soluble in water
Usage: Popular as a laboratory reagent, especially in protein research and biochemistry labs; sometimes used for its inhibitory activity in enzymatic reactions.
Physical State: Solid
Classification: Acute toxicity, Eye irritation, Specific target organ toxicity
Precautionary Symbols: Skull and crossbones, Exclamation mark
Main Risks: Can be harmful if inhaled, swallowed, or if it comes into contact with skin; can cause irritation to eyes, skin, and respiratory system; chronic exposure may impact vital organs, especially the liver and kidneys; dust or solutions pose bigger risks due to easy absorption and accidental ingestion or inhalation.
Component: Sodium Orthovanadate
Concentration: Typically close to 100% in laboratory preparations
Related Elements: Sodium, Vanadium, Oxygen
Other Substances: Minimal if pure; some preparations may show trace ionic impurities.
Vanadium Content: Notable for vanadium as both a trace element and a toxicant.
Inhalation: Move to fresh air and seek immediate help if symptoms like coughing, shortness of breath, or dizziness appear.
Skin Contact: Rinse skin liberally with water and remove contaminated clothing.
Eye Contact: Flush eyes with water for at least 15 minutes, keep lids open, and consult a doctor promptly.
Ingestion: Rinse mouth carefully and do not force vomiting; medical advice is essential, especially if person feels unwell.
General Statement: Rapid, thorough washing and medical assessment matter when anyone gets exposed.
Flammability: Not considered flammable itself, but toxic fumes like sodium oxides and vanadium oxides may evolve if it’s heated to decomposition.
Extinguishing Media: Use regular dry chemical, foam, or CO2; avoid water jets directly on the chemical.
Special Protective Equipment: Firefighters should wear full protective clothing and self-contained breathing apparatus to prevent any contact with hazardous fumes.
Fire Hazards: Combustion can produce irritating, corrosive, and/or toxic gases; closed containers may rupture if strongly heated.
Personal Protection: Don suitable gloves, goggles, and a respirator to prevent intake or skin contact.
Spill Handling: Sweep up the material thoroughly without making dust; use damp materials for smaller releases.
Environmental Caution: Don't let the chemical enter water sources or drains; contain spill using natural barriers or commercial absorbents.
Clean-up: Store collected material in secure, labeled containers for toxic waste disposal.
Ventilation: Open windows or use local exhaust to lower airborne dust concentrations.
Handling: Always keep containers tightly closed and store in clearly labeled, corrosion-resistant bottles.
Storage: Place in a cool, dry, ventilated place, away from acids and incompatible chemicals.
Hygiene: Wash hands after handling, and avoid eating or drinking in work areas.
Spill Preparedness: Keep materials and tools ready for the quick clean-up of accidental leaks.
Respiratory Protection: Use a particulate respirator if the chance of dust generation exists.
Eye Protection: Wear chemical splash goggles or a face shield.
Skin: Gloves made of chemical-resistant material help lessen risk.
Clothing: Use lab coats or aprons to block accidental splashes or spills.
Engineering Controls: Use fume hoods or local exhaust fans in areas with frequent handling.
Hand Washing: Set up wash stations to keep skin clean after contact.
Physical Form: Powder, white or colorless
Melting Point: Around 630°C
Boiling Point: Decomposes before boiling
Water Solubility: Easily dissolves
Odor: Odorless
Vapor Pressure: Not relevant under normal use
Density: Close to 2.8 g/cm³
pH: Alkaline when dissolved in water, giving basic solutions
Stability Under Normal Conditions: No spontaneous breaking down if kept dry.
Stability: Stays stable if dry and kept in sealed containers away from moisture.
Conditions to Avoid: Keep away from acids, moisture, and high heat.
Unwanted Reactions: Will react with strong acids, releasing toxic vanadium oxides.
Hazardous Combustion Products: Sodium oxide and vanadium oxide gases may develop if strongly heated.
Storage Compatibility: Never store with strong acids or reducers.
Acute Exposure Effects: Main issues involve irritation of the skin and eyes, breathing in dust can hurt the lungs, and swallowing it could cause stomach upset, headaches, or vomiting.
Chronic Effects: Long-term exposure links to damage in liver, kidneys, or nervous system, mostly in poorly ventilated or unprotected settings.
Sensitization: Prolonged skin contact can cause allergic reactions for certain people.
Carcinogenicity: Some sources list vanadium compounds as possible carcinogens but evidence in humans stays open to debate.
Additional Notes: Always take personal sensitivity and health background into account.
Environmental Impact: Toxic to aquatic organisms and may linger in soil or sediment.
Bioaccumulation: Vanadium compounds can build up in plants or animals if exposure continues.
Mobility: If spilled, the chemical moves easily through moist soil and into surface water bodies.
Persistence: Not easily broken down by natural biological processes.
Ecosystem Risks: Large, unmanaged spills may disrupt growth and health of fish, algae, or aquatic insects.
Recycling: Not common due to toxicity and specialized use.
Waste Treatment: Should go to a certified hazardous chemical waste facility.
Drain Disposal: Strictly avoid pouring into drains or natural water systems.
Container Clean-up: Rinse containers thoroughly before final disposal and mark as hazardous.
Local Regulation: Always check local rules for handling and disposal of vanadium chemicals.
Shipping Categories: Transported as a hazardous chemical.
Labeling: Package with “Toxic” or “Harmful” hazard markings.
Packaging: Seal in rigid, leak-proof containers.
Transport Precautions: Avoid exposure to wet conditions; secure packages to prevent movement.
Accident Response: Emergency protocols should be clear for those moving the material.
Workplace Limits: Some regions publish exposure limits for vanadium dust and compounds, typically in low milligrams per cubic meter.
Chemical Inventory: Registered under most national and international chemical control regulations.
Labeling: Must have hazard labeling as mandated by occupational safety agencies.
Usage Restrictions: Laboratories and workplaces track and report any significant usage, especially in research settings.
