Hazards and Protection.
Storage
Keep away from heat, sparks, and flame. Do not store near combustible materials. Keep container closed when not in use. Keep under a nitrogen blanket. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from water. Corrosives area. Store protected from moisture.
Handling
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Do not allow water to get into the container because of violent reaction. Minimize dust generation and accumulation. Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Avoid contact with clothing and other combustible materials. Do not ingest or inhale. Use only in a chemical fume hood. Discard contaminated shoes. Keep from contact with moist air and steam.
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 gloves 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.
Small spills/leaks
Clean up spills immediately, using the appropriate protective equipment. Remove all sources of ignition. Provide ventilation. Do not expose spill to water. Do not use combustible materials such as paper towels to clean up spill. Cover with dry earth, dry sand, or other non-combustible material followed with plastic sheet to minimize spreading and contact with water. Stop leak only if you can do so without risk. Use water spray to reduce vapors or divert vapor cloud drift.

Stability
Stable under normal temperatures and pressures. Substance readily absorbs carbon dioxide from air. Combines vigorously or explosively with water. May discolor on exposure to air.
Incompatibilities
Strong reducing agents, reducing agents, acids, acetic acid, acetic anhydride, ammonium persulfate, alcohols, copper, finely powdered metals, magnesium, manganese oxide, zinc, potassium, diethyl ether, peroxyformic acid, combustible organics, calcium acetylide, charcoal, benzene, aniline, hydrogen sulfide, manganese dioxide, glycerine, tin, calcium carbide (powder), hexamethylenetetramine, silver chloride, aluminum chloride, ammonium peroxodisulfate, sulfur monochloride, aluminum + CO2, almond oil, boron nitride, hydroxy compounds (e.g. ethanol, ethylene glycol, gycerol, sugar), nonmetals (e.g. carbon, phosphorous, antimony, arsenic, boron, sulfur, selenium), nonmetal halides (e.g. diselenium dichloride, disulfur dichloride, phosphorus trichloride), paraffin.
Decomposition
Irritating and toxic fumes and gases, sodium oxide.

Fire.
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Strong oxidizer. Contact with combustible materials may cause a fire. Water Reactive. Material will react with water and may release a flammable and/or toxic gas. Will react with water to form toxic and corrosive fumes. May ignite or explode on contact with steam or moist air. Extinguishing media: Do NOT use carbon dioxide. Do NOT use alcohol foams. DO NOT USE WATER! Contact professional fire-fighters immediately. Cool containers with flooding quantities of water until well after fire is out. For large fires use dry sand, dry chemical, soda ash or lime or withdraw from area and let fire burn. For small fires, use dry chemical, soda ash, lime or dry sand.
Fire potential
May ignite combustibles (wood, paper, oil, clothing, etc.).
Hazards
May ignite combustibles (wood, paper, oil, clothing, etc.). React vigorously and/or explosively with water. Produce toxic and/or corrosive substances on contact with water. Flammable/toxic gases may accumulate in tanks and hopper cars. Containers may explode when heated. Runoff may create fire or explosion hazard.
Combustion products
Fire will produce irritating, corrosive and/or toxic gases.

Exposure effects
   Ingestion
The toxicological properties of this substance have not been fully investigated. May cause corrosion and permanent tissue destruction of the esophagus and digestive tract. Ingestion may cause gastritis, esophagitis, vomiting and diarrhea.
   Inhalation
Causes chemical burns to the respiratory tract. The toxicological properties of this substance have not been fully investigated. Inhalation may cause sore throat, shortness of breath, labored breathing, coughing, and pulmonary edema.
   Skin
May cause irritation with burning pain, itching and redness. Causes severe skin irritation and burns.
   Eyes
Causes severe eye irritation and burns. May cause redness, pain, blurred vision and possible eye damage.

First aid
 
   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. 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
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
Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. Extensive irrigation is required (at least 30 minutes).
