| First Aid Measures | Back to Contents | 【Ingestion】
Do NOT induce vomiting. 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】
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. Wash clothing before reuse. | 【Eyes】
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. If irritation develops, get medical aid. |
| Handling and Storage | Back to Contents | 【Storage】
Store in a cool, dry, well-ventilated area away from incompatible substances. Store in opaque, air-tight containers. | 【Handling】
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Do not get on skin or in eyes. Do not ingest or inhale. Store protected from light. |
| Hazards Identification | Back to Contents | 【Inhalation】
May cause respiratory tract irritation. May cause effects similar to those described for ingestion. | 【Skin】
May cause skin irritation. Prolonged and/or repeated contact may cause irritation and/or dermatitis. | 【Eyes】
May cause eye irritation. | 【Ingestion】
May cause irritation of the digestive tract. May cause liver and kidney damage. 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. | 【Hazards】
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. | 【EC Risk Phrase】

| Exposure Controls/Personal Protection | Back to Contents | 【Personal 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. | 【Exposure Effects】
Chronic exposure can lead to iodism characterized by salivation, nasal discharge, sneezing, conjunctivitis, fever, laryngitis, bronchitis, stomatitis, and skin rashes. | 【Poison Class】

| Fire Fighting Measures | Back to Contents | 【Flash Point】
104 | 【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 water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire. Extinguishing media: Use foam, dry chemical, or carbon dioxide. Use agent most appropriate to extinguish fire. Cool containers with flooding quantities of water until well after fire is out. | 【Fire Potential】
Combustible material: may burn but does not ignite readily. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Neutralize spill with sodium bicarbonate. Remove all sources of ignition. Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Carefully scoop up and place into appropriate disposal container. Provide ventilation. |
| Stability and Reactivity | Back to Contents | 【Disposal Code】
2 | 【Incompatibilities】
Alkenes + diethyl zinc, copper-zinc alloys + ether, lithium, potassium, potassium-sodium alloys, strong oxidizing agents, strong bases, light. | 【Stability】
Stable at room temperature in closed containers under normal storage and handling conditions. | 【Decomposition】
Carbon monoxide, carbon dioxide, hydrogen iodide. | 【Combustion Products】
Fire may produce irritating, corrosive and/or toxic gases. |
