First Aid Measures
General Measures: Ensure personal safety, move victim away from exposure, avoid direct contact
Inhalation: Move person to fresh air, keep at rest, monitor breathing, seek medical attention immediately, provide oxygen if breathing is difficult
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water for at least 15 minutes, seek medical attention for irritation or burns
Eye Contact: Rinse cautiously with water for at least 15 minutes, remove contact lenses if present, seek immediate medical attention
Ingestion: Rinse mouth, do not induce vomiting, seek medical attention immediately, never give anything by mouth to an unconscious person
Medical Notes: Treat symptomatically, monitor for delayed effects on kidney and respiratory systems
Fire-Fighting Measures
Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide
Unsuitable Media: Do not use water jet directly onto the chemical powder
Specific Hazards: Toxic gases such as vanadium oxides and sodium oxide may form during combustion
Protective Equipment: Firefighters require self-contained breathing apparatus, full protective clothing
Firefighting Procedures: Isolate hazard area, remove non-involved personnel, keep containers cool with water spray, avoid contamination of water sources
Explosion Hazards: Product does not present explosion hazard, but dust may ignite if mixed with certain organics
Accidental Release Measures
Personal Protection: Wear chemical-resistant gloves, safety goggles, respiratory protection, and protective clothing
Environmental Precautions: Prevent further spillage or leakage, do not allow to enter drains, surface or groundwater
Containment: Avoid dust formation, ventilate area, isolate spill site
Clean-Up Methods: Collect spilled material with suitable tools, place in properly labeled containers for disposal, wash area with water, ventilate thoroughly
Decontamination: Use dilute bleach or sodium bicarbonate for surface neutralization
Handling and Storage
Handling Precautions: Avoid dust and direct contact with skin or eyes, use in well-ventilated areas, handle in accordance with good laboratory hygiene, do not eat, drink or smoke during use
