| First Aid Measures | Back to Contents | 【Ingestion】
If swallowed, wash out mouth with water provided person is conscious. Call a physician. | 【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】
May be harmful if inhaled. Material may be irritating to mucous membranes and upper respiratory tract. | 【Inhalation】
If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen. | 【Inhalation】
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. | 【Skin】
May cause skin irritation. May be harmful if absorbed through the skin. | 【Skin】
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. | 【Skin】
In case of contact, immediately wash skin with soap and copious amounts of water. Remove contaminated clothing and shoes. Call a physician. | 【Eyes】
May cause irritation. | 【Eyes】
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. | 【Eyes】
In case of contact with eyes, flush with copious amounts of water for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers. Call a physician. |

| Exposure Controls/Personal Protection | Back to Contents | 【Personal Protection】
Compatible chemical-resistant gloves. Chemical safety goggles. Protective clothing. | 【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. | 【Respirators】
Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. |
| Fire Fighting Measures | Back to Contents | 【Flash Point】
74 | 【Fire Fighting】
For small (incipient) fires, use media such as 'alcohol' foam, dry chemical, or carbon dioxide. For large fires, apply water from as far as possible. Use very large quantities (flooding) of water applied as a mist or spray; solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes. | 【Fire Fighting】
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Extinguishing media: Use agent most appropriate to extinguish fire. | 【Fire Potential】
Combustible liquid. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Cover with dry-lime, sand, or soda ash. Place in covered containers using non-sparking tools and transport outdoors. Ventilate area and wash spill site after material pickup is complete. | 【Small spills/leaks】
Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. |
