| Hazards and Protection. | |
| Storage | Keep away from sources of ignition. Store in a cool, dry, well-ventilated area away from incompatible substances. |
| WHMIS | B3 D2A |
| Handling | Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Do not get on skin or in eyes. Do not ingest or inhale. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. |
| 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 impervious gloves. 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 | Wear a self contained breathing apparatus and appropriate Personal protection. (See Exposure Controls, Personal Protection section). Remove all sources of ignition. Carefully scoop up and place into appropriate disposal container. |

| Fire fighting | Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Dusts at sufficient concentrations can form explosive mixtures with air. Use water spray to keep fire-exposed containers cool. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. | |||
| Fire potential | Moderate; flammable hazard when exposed to heat, flame or oxidizers. | |||
| Hazards | Containers may explode when heated. | |||
| Combustion products | Vapors are irritating. chlorine, hydrogen chloride, and phosgene gases may be generated in fires. | |||

| Exposure effects | Overexposure may cause delayed kidney injury. Possible cancer hazard based on tests with laboratory animals. Chronic ingestion may cause liver damage. May cause anemia and other blood cell abnormalities. |
| Ingestion | May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause liver and kidney damage. |
| Inhalation | May cause respiratory tract irritation. May cause liver and kidney damage. |
| Skin | May cause skin irritation. |
| Eyes | Exposure to solid may cause pain and redness. Exposure to high vapor concentrations may cause irritation. |
First aid |
|
| Ingestion | If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid immediately. |
| Inhalation | Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid if cough or other symptoms appear. |
| Skin | Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists. |
| Eyes | Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. |
