| Hazards and Protection. | |
| Storage | Store in a cool, dry, well-ventilated area away from incompatible substances. |
| WHMIS | Probably does not meet criteria |
| Handling | Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with skin and eyes. Keep container tightly closed. Avoid ingestion and inhalation. |
| Protection | Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin. |
| Respirators | Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary. |
| Small spills/leaks | Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation. |
| Stability | Stable under normal temperatures and pressures. |
| Incompatibilities | A violent or incandescent reaction with metals (aluminum, calcium, magnesium, potassium, sodium, zinc and lithium) may occur at high temperatures. Substance is incompatible with strong acids. |
| Decomposition | Titanium/titanium oxides. |
| Fire. | ||||
| Fire fighting | Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Non-combustible, substance itself does not burn but may decompose upon heating to produce irritating, corrosive and/or toxic fumes. Extinguishing media: Substance is noncombustible; use agent most appropriate to extinguish surrounding fire. | |||

| Poison_Class | - |
| Exposure effects | Chronic inhalation may cause pulmonary fibrosis. |
| Ingestion | No hazard expected in normal industrial use. May cause gastrointestinal irritation with nausea, vomiting and diarrhea. |
| Inhalation | Dust is irritating to the respiratory tract. May cause pulmonary fibrosis and permanent damage. |
| Skin | Dust may cause mechanical irritation. |
| Eyes | Dust may cause mechanical irritation. |
First aid |
|
| Ingestion | Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid. |
| Inhalation | Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. DO NOT use mouth-to-mouth respiration. |
| Skin | Get medical aid if irritation develops or persists. Wash clothing before reuse. Flush skin with plenty of soap and water. |
| Eyes | Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid. |
