| [Flash Point] -21 | |
| [Autoignition] 240 | |
| [Fire Fighting] DO NOT USE WATER, carbon dioxide OR FOAM ON MATERIAL ITSELF. It may react violently with water. Smothering may not be effect. | |
| [Upper exp. limit] 7.4 | |
| [Lower exp. limit] 1.2 | |
| [Fire Potential] Flammable/combustible material. | |
| [Ingestion] Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Possible aspiration hazard. Get medical aid immediately. | |
| [Inhalation] Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. 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] Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush with running water for at least 20 minutes. | |
| [Eyes] In case of contact with substance, immediately flush with running water for at least 20 minutes. | |
| [Storage] Keep away from heat, sparks, and flame. Keep away from sources of ignition. Keep container closed to prevent drying out. Keep under a nitrogen blanket. Keep from contact with oxidizing materials. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from water. Keep away from organic halogens. Refrigerator/flammables. | |
| [Handling] Remove contaminated clothing and wash before reuse. Ground and bond containers when transferring material. Do not get in eyes, on skin, or on clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Do not ingest or inhale. Do not allow contact with water. Use only in a chemical fume hood. Store and handle protected from air. Do not use if the material has evaporated to dryness. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. | |
| [Ingestion] Aspiration hazard. May cause central nervous system depression, kidney damage, and liver damage. Causes digestive tract burns with immediate pain, swelling of the throat, convulsions, and possible coma. Aspiration of material into the lungs may cause chemical pneumonitis, which may be fatal. May cause corrosion and permanent tissue destruction of the esophagus and digestive tract. May cause ear ringing, blurred vision, thyroid abnormalities, photophobia, coma, and seizures. | |
| [Inhalation] high concentrations may cause central nervous system effects characterized by headache, dizziness, unconsciousness and coma. Irritation may lead to chemical pneumonitis and pulmonary edema. Causes severe irritation of upper respiratory tract with coughing, burns, breathing difficulty, and possible coma. May cause effects similar to those described for ingestion. | |
| [Skin] Contact with substance may cause severe burns. | |
| [Eyes] Causes severe eye burns. May cause irreversible eye injury. | |
| [Hazards] May ignite on contact with moist air or moisture. May burn rapidly with flare-burning effect. May react vigorously or explosively on contact with water. May decompose explosively when heated or involved in a fire. May re-ignite after fire is extinguished. | |

| [Small spills/leaks] Use a fully encapsulating, vapor protective clothing should be worn for spills and leaks with no fire. ELIMINATE all ignition sources and prevent all contact with spilled material. Stop leak if you can do it without risk. Cover with DRY earth, DRY sand, or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain. Use clean non-sparking tools to collect material and place it into loosley covered plastic containers for later disposal. This is a generic DOT guideline. EXCEPTION: For Dithionite (Hydrosulfite/Hydrosulphite) spills, UN1384, UN1923 and UN1929, dissolve with 5 parts water and collect for proper disposal. | |
| [Incompatibilities] Incompatible materials, ignition sources, exposure to air, contact with water, organic materials, strong oxidants, exposure to moist air or water, dehydrating agents. | |
