Manganese nitrate is a colorless to pink crystalline solid. Molecular weight= 178.96. Hazard Identification (based on NFPA-704 M Rating System): Health 3, Flammability 0, Reactivity 3 (Oxidizer). Highly soluble in water.
Manganese(II) nitrate is used as a precursor to prepare the oxides of manganese. It is involved in the preparation of electronic components. Further, it is utilized for the phosphorous treatment of metal surface.
Ceramics, intermediates, catalyst, manganese
dioxide.
A white crystalline solid. Denser than water. May ignite on contact with organic matter. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion. Used to make other chemicals.
Mixtures of metal/nonmetal nitrates with alkyl esters may explode, owing to the formation of alkyl nitrates; mixtures of nitrate with phosphorus, tin (II) chloride, or other reducing agents may react explosively [Bretherick 1979. p. 108-109]. The anhydrous nitrate salt with urea explodes upon heating, [Chem Abs., 1975, 82, 48151].
Fire and explosion risk in contact with
organic materials.
Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.
These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.
Mutation data reported.
When heated to decomposition it emits
toxic vapors of manganese.
Manganese nitrate is used as a color agent in porcelain and ceramic manufacture, as a catalyst, and in the production of manganese dioxide.
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 2448 h after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a corticosteroid spray.
Color Code—Yellow: Reactive Hazard (strong oxidizer); Store in a location separate from other materials, especially flammables and combustibles. Prior to working with this chemical you should be trained on its proper handling and storage. Manganese nitrate must be stored to avoid contact with organic materials since violent reactions occur. Store in tightly closed containers in a cool, well-ventilated area. Where possible, automatically transfer material from drums or other storage containers to process containers. See OSHA Standard 1910.104 and NFPA 43A Code for the Storage of Liquid and Solid Oxidizers for detailed handling and storage regulations.
This compound requires a shipping label of “OXIDIZER.” It falls in Hazard Class 5.1 and Packing Group III.
A strong oxidizer. Violent reaction with reducing agents, organics, and combustible materials.
