| Hazards and Protection. | |
| Storage | Keep container closed when not in use. Store in a cool, dry, well-ventilated area away from incompatible substances. |
| Handling | Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well ventilated area. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. 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 protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure. |
| 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 | Clean up spills immediately, using the appropriate protective equipment. Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Avoid generating dusty conditions. Provide ventilation. |
| Stability | Stable under normal temperatures and pressures. |
| Incompatibilities | Strong oxidizing agents, strong bases, alkali metals, magnesium, lithium, acetone, silver nitrate, mercuric oxide, calomel, tannin, balsam peru. |
| Decomposition | Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, hydrogen iodide. |

| Flash Point,°C | 204 | |||
| 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. To extinguish fire, use water fog, dry chemical, carbon dioxide, or regular foam. Use agent most appropriate to extinguish fire. | |||

| Poison_Class | 2 |
| Exposure effects | Headache, dizziness, confusion, delirium, and hallucinations may be noted following severe intoxication. Seizure has been reported following mediastinal irrigation. |
| Ingestion | Harmful if swallowed. May cause gastrointestinal irritation with nausea, vomiting and diarrhea. |
| Inhalation | Harmful if inhaled. May cause respiratory tract irritation. |
| Skin | May be absorbed through the skin. May cause dermatitis. |
| Eyes | Causes eye irritation. |
First aid |
|
| Ingestion | If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately. |
| Inhalation | Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. |
| Skin | Get medical aid immediately. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. |
| Eyes | Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. |
