| Hazards and Protection. | |
| Storage | Keep away from heat, sparks, and flame. Store in a cool, dry place. Keep from contact with oxidizing materials. Do not store in metal containers. Keep containers tightly closed. |
| WHMIS | D1B D2B |
| Handling | Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Do not reuse this container. |
| 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 | Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Clean up spills immediately, using the appropriate protective equipment. Flush spill area with water. A vapor suppressing foam may be used to reduce vapors. |
| Stability | Stable under normal temperatures and pressures. |
| Incompatibilities | Strong oxidizing agents, strong bases, ammonia, Active metals (such as potassium and magnesium). |

| Fire fighting | Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Extinguishing media: For small fires, use dry chemical, carbon dioxide, halon, or water spray. For large fires, use water spray, fog or regular foam. Cool containers with flooding quantities of water until well after fire is out. | |||
| Fire potential | No statement of flammability in national fire codes. | |||
| Hazards | Air/vapor mixtures may explode when ignited. Container may explode in heat of fire. | |||
| Combustion products | Toxic gases including hydrogen chloride and very small amounts of phosgene and chlorine are produced. | |||

| Poison_Class | 3 |
| Exposure effects | May cause liver and kidney damage. |
| Ingestion | May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause central nervous system depression, characterized by excitement, followed by headache, dizziness, drowsiness, and nausea. Advanced stages may cause collapse, unconsciousness, coma and possible death due to respiratory failure. May be harmful if swallowed. |
| Inhalation | Inhalation of high concentrations may cause central nervous system effects characterized by nausea, headache, dizziness, unconsciousness and coma. Causes respiratory tract irritation. Long-term vapor exposure to 1,1,2-trichloroethane causes chronic gastric symptoms, fat deposition in the kidneys, and damage to the lungs. |
| Skin | May be absorbed through the skin in harmful amounts. Exposure may cause irritation characterized by redness, dryness, and inflammation. |
| Eyes | May cause eye irritation. May cause eye injury. |
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. 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. |
