Chemical Name: Vanadium Tetrachloride
CAS Number: 7632-51-1
EC Number: 231-588-9
Concentration: 100% (pure compound)
Impurities: No additional components relevant for hazard classification.
Formula: VCl4
Inhalation: Move person to fresh air promptly. Supply oxygen if breathing is difficult. Seek medical attention without delay.
Skin Contact: Remove contaminated clothing quickly. Wash affected skin thoroughly with soap and water for at least 15 minutes. Get medical attention for burns or persistent irritation.
Eye Contact: Rinse eyes cautiously with water for several minutes, keeping eyelids open. Remove contact lenses, if present and easy to do. Immediate medical attention is critical.
Ingestion: Do not induce vomiting. Rinse mouth with water. Never give anything by mouth to an unconscious person. Get urgent medical advice.
General Advice: Always seek prompt professional healthcare following any significant exposure.
Suitable Extinguishing Media: Dry chemical, carbon dioxide, or alcohol-resistant foam. Water may react violently with vanadium tetrachloride, releasing hazardous fumes.
Unsuitable Extinguishing Media: Never use water directly on material.
Hazards from Combustion Products: Liberates toxic and corrosive hydrogen chloride and vanadium oxides under fire conditions.
Special Protective Equipment: Wear self-contained breathing apparatus and full protective gear. Acute care against direct exposure to fumes is important.
Special Fire-Fighting Procedures: Remove all persons not involved in extinguishing operations. Cool containers with fog from a safe distance if possible.
Personal Precautions: Evacuate area. Wear appropriate personal protective equipment, including respiratory protection.
Environmental Precautions: Prevent spillage from entering drains, watercourses, or the soil.
Cleanup Methods: Neutralize residue with lime or soda ash. Absorb liquid with inert, non-combustible material and place in suitable chemical waste container. Ventilate area well. Decontaminate tools and surfaces.
Protective Actions: Remove sources of ignition. Restrict access to affected area. Avoid formation of dust or aerosols.
Precautions for Safe Handling: Work in chemical fume hood to reduce exposure risk. Avoid breathing vapor and prevent skin or eye contact. Use robust chemical-resistant gloves, splash-proof goggles, and laboratory coats.
Storage Conditions: Store in cool, dry, and well-ventilated space away from incompatible substances such as moisture, alkali metals, and oxidizing agents.
Storage Containers: Use corrosion-resistant tightly sealed containers.
Incompatible Materials: Keep separate from water, alcohols, amines, metals, and strong bases.
Hygiene Measures: Wash hands, face, and exposed skin thoroughly after handling. Do not eat, drink, or smoke in work areas.
Occupational Exposure Limits: No established OSHA PEL or ACGIH TLV; exposures should be minimized based on national guidelines for vanadium compounds.
Engineering Controls: Local exhaust ventilation or fume hood required for safe operation.
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), chemical safety goggles, face shield, lab coat or coveralls, and suitable respiratory protection for inadequate ventilation.
Respiratory Protection: Use NIOSH-approved air-purifying respirator with acid gas cartridge.
Environmental Exposure Controls: Use secondary containment to minimize risk of environmental release.
