| [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. | |
| [Fire Potential] Combustible material: may burn but does not ignite readily. | |
| [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] Get medical aid immediately. Remove from exposure to fresh air immediately. 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. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes. | |
| [Eyes] Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. Extensive irrigation is required (at least 30 minutes). | |
| [Storage] Keep container closed when not in use. Store in a cool, dry, well-ventilated area away from incompatible substances. Corrosives area. | |
| [Handling] Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Do not ingest or inhale. Use with adequate ventilation. Discard contaminated shoes. | |
| [Inhalation] Causes chemical burns to the respiratory tract. Aspiration may lead to pulmonary edema. May cause systemic effects. | |
| [Skin] Causes skin burns. May cause skin rash (in milder cases), and cold and clammy skin with cyanosis or pale color. | |
| [Eyes] Causes eye burns. May cause chemical conjunctivitis and corneal damage. | |
| [Ingestion] May cause severe and permanent damage to the digestive tract. Causes gastrointestinal tract burns. May cause perforation of the digestive tract. May cause systemic effects. | |
| [Hazards] When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. | |
