| Hazards and Protection. | |
| Storage | Materials which are toxic as stored or which. Decomp into toxic components due to contact with heat. Should be stored in cool, well-ventilated place, out of direct rays of sun, away from areas of high fire hazard, and periodically inspected and monitored. |
| Handling | All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood. |
| Protection | Wear rubber gloves, self-contained breathing apparatus, overalls. Wear appropriate clothing to prevent any possibility of skin contact with molten material or solutions. Wear eye protection and wash promptly when skin is contaminated. Wear appropriate personal protective clothing and eye protection to prevent contact. |
| Respirators | Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode. Any appropriate escape-type, self-contained breathing apparatus. |
| Small spills/leaks | Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces. |
| Stability | No data. |
| Incompatibilities | Strong oxidizing agents. |
| Decomposition | When heated to decomposition, it emits highly toxic fumes of hydrogen chloride. |
| 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. Use agent most appropriate to extinguish fire. | |||
| Fire potential | Noncombustible | |||

| Exposure limit(s) | TLV (as TWA): ppm; 0.5 mg/m3 (skin) (ACGIH 1995-1996). OSHA PEL: TWA 0.5 mg/m3 skin NIOSH REL: TWA 0.5 mg/m3 skin |
| Exposure effects | CNS depression and coma may be seen. |
| Skin | Acneiform rashes and chloracne have been reported in exposed workers. |
First aid |
|
| Ingestion | Administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. Consider after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). If hepatic failure occurs, intensive supportive therapy should be provided. |
| Inhalation | Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols. |
| Skin | Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. A variety of topical treatments may useful if chloracne occurs. Dermatologic consultation is suggested. |
| Eyes | Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility. |
