2. Composition: Ammonium Nitrate(NH4NO3) 97.1% Cas # 6484-52-2 Magnesium Nitrate Mg(NO3)2 1.6% Cas # 10213-15-7 Inert Ingredients 1.3% (See section 8 of this MSDS for exposure guidelines)
3. Hazards Identification: Emergency Overview White to clear prills, odorless. Possible irritant to eyes and skin. Ammonium Nitrate is classified as an oxidizer yet has a negligible fire hazard when exposed to heat or flame. Product can present a dangerous explosive hazard, with heat or flame, under confined conditions, or if contaminated with organics or certin metals. Potential Health Hazards: INHALATION: Finely divided dust can cause acute irritation of the respiratory tract, such as sore throat, coughing, and bronchial congestion. Prolonged exposure can cause allergic reactions. SKIN CONTACT: May cause irritating redness, repeated or prolonged exposure may result in dermatitis. EYE CONTACT: As with any salt, can result in irritation or redness. Prolonged or repeated exposure may cause conjunctivitis. INGESTION: Ingestion may cause mild gastric irritation, nausea and faintness. Repeated or prolonged ingestion may cause anemia, methemoglobinemia and nephritis, with exagerated symptons in infants.
4. First Aid: INHALATION-Remove from exposure into fresh air. Perform artificial respiration, if not breathing. Keep person warm and get medical help at once. SKIN-Remove contaminated clothing and flood affected area with water. Wash with mild detergent of soap and rinse with large amounts of water. Get medical help at once. EYES-Flush eyes with large amounts of water or normal saline solution until all evidence of material is removed. Obtain medical attention at once. INGESTION-Give large amounts of milk. Do not give anything by mouth if person is unconscious or unable to swallow. Obtain medical attention at once.
5. Fire Fighting Measures: OXIDIZER: [ Explosion hazard if confined ] Use large quantities of water. Use coarse spray or stream, do not use mist or steam. Do not use carbon dioxide, halon or dry chemical extinguisher. If material is contained do not cover or restrict fire in any way. Cool container with large volumes of water. Do not attempt to move vehicles or containers. If material is in rail car or tank truck, isolate for at least 1/2 mile radius. (1996 Emergency Response Guidebook Guide 140)
6. Accidental Release Measures: Do not walk or run equipment through spilled material. Clean up solid spills using mechanical means. If uncontaminated return to process or use as fertilizer. Do not wash down contaminated area or allow solids to come in contact with surface or ground waters. Contaminated material must be disposed of in accordance with local, state and federal guidelines.
7. Handling and Storage Store materials in non combustible, sprinkler controlled, well ventilated, buildings. Keep storage areas clean and free from contamination. Do not weld or cut on containers holding Ammonium Nitrate are in the vicinity of stored Ammonium Nitrate. Store bagged material in well ventilated areas keeping the stack at least 30 inches from the wall and 36 inches from the roof. Allow passages and ventilation between stacks. Do not weld or cut inside a building containing ammonium nitrate. (NFPA Code 490].
8. Exposure Control & Personal Protective Equipment Appropriate engineering controls, such as ventilation and dust controls, should be installed to reduce dust and confinement of materials. RESPIRATORY In areas where dust will be generated respirators are required. They must meet NIOSH and MSHA standards. Under normal conditions, dust and mist respirators must be equipped with efficient particulate filters. Dust loading in the work area dictates the level of protection required. CLOTHING Under normal conditions cotton work clothing w/long selves is sufficient. Dust loading in the work area dictates the level of protection required EYE PROTECTION Under normal conditions safety glasses and/or chemical goggles are acceptable. EXPOSURE GUIDELINES: OSHA and ACGIH have not established exposure limits for Ammonium Nitrate or Magnesium Nitrate. Normal precautions should be taken when exposed to dust generated by these materials. GLOVES Neoprene chemical resistant work gloves are necessary to prevent contact with the skin
9. Physical & Chemical Properties: Appearance White to clear prills Odor None Odor threshold level Unknown Physical state Solid, Prills pH 5.4 Vapor pressure N/A Vapor density N/A Melting point 338F Boiling point 410F (Decomposes) Solubility in water 118% @ 0 C Solubility(other Acetone, Ammonia & Methanol than water): Specific gravity 1.7 (water=1) Evaporation rate N/A Viscosity N/A Volatility N/A
10. Stability and Reactivity: Ammonium Nitrate is capable of undergoing detonation if heated under confinement, or is subjected to very strong shocks. Organic oxidizable matter can sensitize the material into a more readily explosive state. Ammonium Nitrate is incompatible with most inorganic and organic acids, strong alkalis, chloride salts, metals (such as copper, aluminum, zinc, magnesium, potassium etc.), organic fuels and reducing agents. Thermal decomposition is normally rapid with the release of toxic and corrosive fumes of ammonia, oxides of nitrogen and nitric acid. Hazardous polymerization will not occur.
11. Toxicological Information: ORAL: 2217 mg/Kg oral-rat LD50 CARCINOGEN STATUS: None LOCAL EFFECTS:inhalation, skin, eye. ACUTE TOXIC LEVEL: Moderately toxic by ingestion TARGET EFFECTS: Poisoning may affect the blood.
12. Ecological Information: Solid Ammonium Nitrate is widely used as a fertilizer material. There have been reports of excessive nitrates in groundwater resulting from its use as a fertilizer. Strong Ammonium Nitrate solutions can contaminate surface and groundwater. Harm to vegetation and aquatic life can occur. Vegetation kills may result from excess runoff during clean up or fire fighting.
13. Disposal Considerations: Where possible the material should be picked up dry and stored in secure waterproof containers. All containers must be properly labeled and transported in accordance with DOT regulations. Solid ammonium nitrate is classified as a characteristic waste (Oxidizer) by RCRA and must be handled as such for disposal.. If material is clean it may be returned to process or used as a fertilizer. Contaminated or waste material must be disposed of in accordance with local, state and federal guidelines. Ammonium Nitrate solution has recently been delisted from the toxic release inventory under section 313 of SARA Title III. Water soluble Nitrate salts have been added to the list of reportable materials.
14. Transportation Bags, shipping containers must carry the proper placard or label: Ammonium Nitrate Fertilizer, 34% N UN # 1942 Class 5.1
15. Regulatory information: RCRA: Not specifically listed but oxidizers are characteristic waste under this regulation. CERCLA Not Listed SARA EHS Not Listed SARA Title III- TRI Not Listed (Covered in Nitrate Compounds Catagory) CAA Not Listed 29CFR SUBPART Z Not Listed NIOSH Not Listed
16. Other Information: As long as the product is stored in the original bag or container all labels and placards must be in place. If the material is repackaged the new container must be properly labeled, in accordance with OSHA, DOT and any other applicable regulation.
