SECTION 2: Hazards identification

EMERGENCY OVERVIEW Appearance: white to gray to brown. Danger! Strong oxidizer. Contact with other material may cause a fire. May cause eye and skin irritation. May cause methemoglobinemia. Causes respiratory tract irritation. Target Organs: Red blood cells.

Potential health effects

Eye: Causes eye irritation. Skin: May cause skin irritation. Ingestion: Ingestion of large amounts may cause gastrointestinal irritation. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate and chocolate-brown colored blood. Inhalation: May cause methemoglobinemia, cyanosis, convulsions, tachycardia, dyspnea (labored breathing), and death. May cause severe irritation of the respiratory tract with sore throat, coughing, shortness of breath and delayed lung edema. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate and chocolate-brown blood. Inhalation can cause systemic acidosis and methemoglobinemia. Chronic: May cause methemoglobinemia, which is characterized by chocolate-brown colored blood, headache, weakness, dizziness, breath shortness, cyanosis (bluish skin due to deficient oxygenation of blood), rapid heart rate, unconsciousness and possible death. May cause digestive tract disturbances. - First Aid Measures http://avogadro.chem.iastate.edu/msds/nh4no3.htm (1 of 5) [10/8/2013 12 56 06 PM] Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid. Skin: Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Ingestion: If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anythi ng by mouth to an unconscious person. Get medical aid. Inhalation: Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. Notes to Physician: Absorption of this product into the body may cause cyanosis (bluish disco loration of skin due to deficient oxygenation of the blood). Moderate degrees of cyanosis need to be treated only by supportive measures: bed rest and oxygen inhalation. For methemoglobinemia, administer oxygen alone or with Methylene blue depending on the methemoglobinemia concentration in the blood. Cleansing of the entire contaminated area of the body is of utmost importance. Section 5 - Fire Fighting Measures General Information: Strong oxidizer. Contact with combustible materials may cause a fire. Wear appropriate protective clothing to prevent contact with skin and eyes. Wear a self-contained breathing apparatus (SCBA) to prevent contact with thermal decomposition products. May explode under confinement and high temperatures, especially if contaminated. Extinguishing Media: Use water spray to cool fire-exposed containers. Use flooding quantities of water. Section 6 - Accidental Release Measures General Information: Use proper personal protective equipment as indicated in Section 8. Spills/ Leaks: Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, observing precautions in the Protective Equipment section. Avoid generating dusty conditions. Remove all sources of ignition. - Handling and Storage Handling: Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Avoid contact with heat, sparks and flame. Avoid contact with clothing and other combustible materials. Avoid ingestion and inhalation. Keep away from clothing and other combustible materials. Do not pressurize, cut, weld, braze, solder, drill, grind, or exp ose empty containers to heat, sparks or open flames.

Storage

Keep away from sources of ignition. Do not store near combustible materials. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible subst ances. Keep away from acids. Keep away from reducing agents.

CAS NUMBER: 7664-41-7 EXPOSURE LIMITS: OSHA: PEL = 50 ppm ACGIH: TLV/TWA = 25 ppm NIOSH: IDLH = 300 ppm TLV-STEL = 35 ppm | SECTION | EMERGENCY OVERVIEW Anhydrous Ammonia is an irritating, flammable, and colorless liquefied compressed gas packaged in cylinders under its own vapor pressure of 114 psig at 70 °F. Ammonia can cause severe eye, skin and respiratory tract burns. It poses an immediate fire and explosion hazard when concentrations exceed 15%; therefore, area must be ventilated before entering. Wear self-contained breathing apparatus (SCBA) when entering release area if concentrations exceed allowable exposure limits. Fully protective suits are required in large releases. Always be aware of fire and explosion potential in the case of large releases. EMERGENCY TELEPHONE NUMBERS (800) 523-9374 Continental U.S., Canada, and Puerto Rico (610) 481-7711 other locations

Principle Routes of Exposure

EYE CONTACT: Exposure to Ammonia can cause moderate to severe eye irritation. INGESTION: Ingestion is not a likely route of exposure for Ammonia. INHALATION: Ammonia is severely irritating to nose, throat, and lungs. Symptoms may include burning sensations, coughing, wheezing, shortness of breath, headache and nausea. Overexposure may also cause central nervous system effects including unconsciousness and convulsions. Upper airway damage is more likely and can result in bronchospasm (closing of the airway). Vocal chords are particularly vulnerable to corrosive effects of high concentrations. Lower airway damage may result in fluid build up and hemorrhage. Death has occurred following a 5 minute exposure to 5000 ppm. MSDS #1003 Ammonia Page 1 of 6 Pub # 320-709 SKIN CONTACT: Vapor contact may cause irritation and burns. Contact with liquid may cause freezing of the tissue accompanied by corrosive caustic action and dehydration. POTENTIAL HEALTH EFFECTS OF REPEATED EXPOSURE: Inhalation, eye or skin contact SYMPTOMS: Repeated or prolonged skin exposure may cause dermatitis. TARGET ORGANS: Eyes, skin, central nervous and respiratory systems. MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE: Conditions generally aggravated by exposure include asthma, chronic respiratory disease (e.g., emphysema), dermatitis and eye disease. CARCINOGENICITY: Ammonia is not listed as a carcinogen or potential carcinogen by NTP, IARC, or OSHA. |
