Precautionary Statements: Avoid all contact with skin, eyes, and clothing, keep away from moisture, use in a ventilated area, never breathe dust or vapors, wash after handling
Routes of Exposure: Eyes, skin, inhalation, ingestion
Chemical Identity: Titanium (III) chloride
Formula: TiCl3
Purity: Commonly provided at 98%–99% pure
Other Components: May contain traces of hydrochloric acid or other titanium chloride species
Inhalation: Move person to fresh air right away, provide artificial respiration if breathing stops, seek medical attention for any breathing difficulty
Skin Contact: Remove contaminated clothing, flush skin with copious water for 20 minutes, do not rub or use neutralizing solutions, call a physician immediately
Eye Contact: Rinse eyes with water for at least 20 minutes, pulling eyelids apart, avoid letting water run to unaffected eye, seek immediate ophthalmologic care
Ingestion: Rinse mouth, do not induce vomiting, give plenty of water if conscious, seek professional medical help promptly
Note to Physician: Treat symptomatically, consider risk of corrosive injury, risk of pulmonary edema or chemical pneumonitis after significant exposure
Suitable Extinguishing Media: Dry sand or Class D powder extinguisher for small fires, avoid using water, carbon dioxide or foam as substance reacts violently with water
Specific Hazards: Releases toxic hydrogen chloride gas and titanium oxides on heating or burning, serious risk if water contacts material
Protective Equipment: Full protective gear and self-contained breathing apparatus, isolate area
Special Procedures: Evacuate people downwind, use non-combustible barriers if material spills or is involved in fire, avoid inhalation of combustion gases
Personal Precautions: Ensure adequate ventilation, avoid dust, wear appropriate respirator, gloves, face shield, chemical-resistant suit
Environmental Precautions: Prevent material from entering sewers, drains, or waterways, contain spillage quickly with inert, dry material
Cleanup Methods: Scoop up using non-sparking tools, never add water, transfer to a closed dry waste vessel, ventilate the area well, wash area with plenty of water after cleanup
Decontamination: Neutralize surfaces with dilute sodium bicarbonate solution after mechanical removal if safe and recommended
Handling: Work under inert atmosphere if possible, avoid all contact, do not breathe dust or fumes, do not eat, drink, or store food in work area, keep containers tightly closed, wash hands before breaks
Storage: Store away from sources of moisture, tightly sealed in moisture-proof containers, store in cool, dry, well-ventilated area, keep away from incompatible materials like water, oxidizers, and organics
Storage Class: Corrosive inorganic solids
Incompatibilities: Water, moisture, hydroxides, bases, metals, oxygen, organics
Exposure Limits: No established OSHA or ACGIH limits, limit airborne dust with engineering controls
Engineering Controls: Local exhaust ventilation, chemical fume hood, air monitoring if handling in quantity
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), lab coat or apron, full-face shield, safety goggles, NIOSH-approved respirator for particulates and acidic gases
