| First Aid Measures | Back to Contents | 【Ingestion】
Causes gastrointestinal irritation with nausea, vomiting and diarrhea. The toxicological properties of this substance have not been fully investigated. | 【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. | 【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 not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. | 【Inhalation】
Causes respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. | 【Skin】
Causes skin irritation. May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. The toxicological properties of this material have not been fully investigated. | 【Skin】
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. | 【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 immediately. | 【Eyes】

| Hazards Identification | Back to Contents | 【Inhalation】
May cause effects similar to those described for ingestion. May cause asthma and shortness of breath. | 【Skin】
Causes skin irritation. May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. If absorbed, may cause symptoms similar to those for ingestion. May cause a deep staining of the skin. May cause severe dermatitis and urticaria(hives). | 【Eyes】
Causes eye irritation. May cause blepharitis (inflammation of the eyelids), keratoconjunctivitis and corneal opacity. May cause severe inflammation and edema of the eye and conjunctiva or deeper structures of the eye. May produce lacrimation and permanent blindness. | 【Ingestion】
May cause irritation of the digestive tract. May cause methemoglobinemia, cyanosis, convulsions, and death. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate and chocolate-brown colored blood. Ingestion may cause gastritis, vertigo, tremors, convulsions, and possible coma. | 【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 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】
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use. | 【Exposure Effects】
Chronic inhalation and ingestion may cause effects similar to those of acute inhalation and ingestion. | 【Exposure Effects】
Prolonged or repeated skin contact may cause sensitization dermatitis and possible destruction and/or ulceration. | 【Exposure limit(s)】

| Fire Fighting Measures | Back to Contents | 【Flash Point】
169 | 【Autoignition】
520 | 【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. Extinguishing media: Use agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam. | 【Fire Fighting】
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Extinguishing media: Use water spray to cool fire-exposed containers. For small fires, use dry chemical, carbon dioxide, or water spray. Cool containers with flooding quantities of water until well after fire is out. For large fires, use water spray, fog or regular foam. | 【Fire Potential】
This chemical is combustible. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions. Provide ventilation. | 【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. |
