Hazards and protection. | |
| Storage | Keep container closed when not in use. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. |
| Handling | Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use with adequate ventilation. Wash clothing before reuse. |
| 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 | A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use. Wear a NIOSH/MSHA or European Standard EN 149 approved full-facepiece airline respirator in the positive pressure mode with emergency escape provisions. |
| Small spills or 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 at room temperature in closed containers under normal storage and handling conditions. |
| Incompatibilities | Strong acids, strong bases. |
| Hazardous Decomposition | Hydrogen chloride, nitrogen oxides, carbon monoxide, irritating and toxic fumes and gases, carbon dioxide. |

| Special | - | |||
| 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. Substance is nonflammable. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. | |||
| Fire potential | Nonflammable. | |||
| Combustion products | Irritating hydrogen chloride and toxic oxides of nitrogen may be formed. | |||

| Exposure limit(s) | TLV: ppm; 5 mg/m3 (ACGIH 1993-1993). NIOSH REL: TWA 5 mg/m3 |
Exposure effects | |
| Effects may be delayed. Possible risk of irreversible effects. | |
| Ingestion | May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May be harmful if swallowed. |
| Inhalation | Causes respiratory tract irritation. May be harmful if inhaled. Can produce delayed pulmonary edema. |
| Skin | May cause skin irritation. May cause sensitization by skin contact. |
| Eyes | Causes eye irritation. May cause chemical conjunctivitis. |
| First aid | |
| Ingestion | Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water. |
| Inhalation | Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. |
| Skin | Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. |
| Eyes | Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid. |
