| First Aid Measures | Back to Contents | 【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 breathing is difficult, give oxygen. Get medical aid. DO NOT use mouth-to-mouth respiration. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask. | 【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. |
| Handling and Storage | Back to Contents | 【Storage】
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. | 【Handling】
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. |

| 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 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. | 【Exposure Effects】
Effects may be delayed. Possible risk of irreversible effects. |
| Fire Fighting Measures | Back to Contents | 【Flash Point】
132 | 【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. Containers may explode when heated. Non-combustible, substance itself does not burn but may decompose upon heating to produce irritating, corrosive and/or toxic fumes. Runoff from fire control or dilution water may cause pollution. Extinguishing media: Use water spray to cool fire-exposed containers. For small fires, use dry chemical, carbon dioxide, or water spray. For large fires, use dry chemical, carbon dioxide, alcohol-resistant foam, or water spray. | 【Fire Potential】
This material is probably combustible. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation. |
| Stability and Reactivity | Back to Contents | 【Disposal Code】
9 | 【Incompatibilities】
Oxidizing agents. | 【Stability】
Stable at room temperature in closed containers under normal storage and handling conditions. | 【Decomposition】
Nitrogen oxides, carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, nitrogen. | 【Combustion Products】
Fire may produce irritating, corrosive and/or toxic gases. |
