| [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. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. | |
| [Fire Potential] This material is probably combustible. | |
| [Ingestion] Never give anything by mouth to an unconscious person. Get medical aid immediately. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water. | |
| [Inhalation] Get medical aid immediately. Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. Do not use mouth-to-mouth respiration if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. | |
| [Skin] Get medical aid immediately. 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] Immediately 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] Corrosives area. Keep containers tightly closed. Store protected from light. Store in a cool, dry area away from incompatible substances. | |
| [Handling] Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well ventilated area. Minimize dust generation and accumulation. Do not get in eyes, on skin, or on clothing. Do not ingest or inhale. Store protected from light. 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. Contact with the skin may cause photosensitivity. May cause skin rash (in milder cases), and cold and clammy skin with cyanosis or pale color. May cause erythema and blistering. | |
| [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 be harmful if swallowed. May cause systemic effects. May cause nausea, insomnia, nervousness, and depression. May cause liver damage in sufficient quantities. | |
| [Hazards] When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. | |

| [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] 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] Effects may be delayed. | |
