Fire-Fighting Measures

Suitable Extinguishing Media: Dry powder, sand, class D extinguishing agents
Do Not Use: Water or CO2, risk of violent reaction
Specific Hazards: Emits toxic metal oxide fumes on burning, fine powder can ignite spontaneously
Protective Equipment: Firefighters must wear self-contained breathing apparatus and full protective gear
Special Precautions: Remove containers from fire area if safe, isolate hazard area, keep out unprotected personnel

Accidental Release Measures

Personal Precautions: Evacuate unnecessary personnel, ventilate area, avoid dust formation, wear particulate respirator, gloves, and goggles
Response Procedure: Sweep up with minimal dust generation, place in a dry, sealed container, use non-sparking tools
Environmental Precautions: Prevent entry into drains, waterways, soil
Decontamination: Use only dry cleaning methods, do not flush residues with water

Handling and Storage

Safe Handling Practices: Work in well-ventilated settings, minimize dust, ground all handling equipment, avoid inhaling particle-laden air, keep away from food and tobacco
Storage Conditions: Store in dry, airtight containers, away from heat and sources of ignition, segregate from oxidizers and acids
Incompatible Materials: Moisture, strong oxidizing agents, acids, halogens
Storage Temperature: Ambient conditions, protect from humidity

Exposure Controls and Personal Protection

Occupational Exposure Limits: OSHA PEL: 0.05 mg/m³ (as vanadium pentoxide dust)
Engineering Controls: Local exhaust ventilation, process isolation, dust extraction systems
Personal Protective Equipment: NIOSH-approved respirators for particulates, chemical-resistant gloves, safety goggles, protective clothing
Hygiene Measures: Wash thoroughly after handling, do not eat or drink while using vanadium powder, shower and change clothes after work

Hazardous Reactions: Risk of spontaneous ignition as an airborne dust, reacts violently with oxidizers

Toxicological Information

Likely Routes of Exposure: Inhalation, skin contact, eye contact
Symptoms: Metal fume fever, bronchitis, persistent cough, abdominal pain, skin redness and irritation, conjunctivitis
Acute Toxicity: May cause serious respiratory irritation and systemic effects if inhaled
Chronic Toxicity: Prolonged exposure can damage lungs, kidneys, cause central nervous system symptoms
Carcinogenicity: Not classified as carcinogenic by IARC, NTP, OSHA
Other Data: Animal studies found inflammation and necrosis after repeated high exposures

Ecological Information

Environmental Fate: Insoluble in water, particles settle in soil and sediment
Aquatic Toxicity: Vanadium ions are toxic to aquatic organisms, even at low concentrations
Soil Mobility: Low mobility for metallic vanadium, increased mobility if oxidized
Persistence and Degradability: Metal powder does not degrade, accumulates in sediments
Bioaccumulation Potential: Vanadium can build up in aquatic food chains

Disposal Considerations

Waste Treatment Methods: Collect and dispose of powder in accordance with local, state, and federal regulations
Disposal Precautions: Do not release to environment, prevent dust emissions, handle as hazardous waste
Contaminated Packaging: Decontaminate or dispose of used containers as hazardous material
Other Notes: Seek advice from authorized chemical waste disposal company
