Ammonia, Anhydrous; 82-0-0 contains 0.2% water

2.1 Classification of the substance or mixture

Toxic, corrosive and non-flammable gas Other Regulations: Toxic gas, Placard colour white Read the entire MSDS for the complete hazard evaluation of this product. First Aid Procedures When: Inhaled: Move victim to fresh air, give artificial respiration only if breathing has stopped. Give cardiopulmonary resuscitation (CPR) if there is no breathing and no pulse. Oxygen administration may be beneficial in this situation but should only be administered by personnel trained in its use. Obtain medical attention immediately. MSDS Anhydrous Ammonia, C-grade Page2/6 Jan. 26, 2016 In Contact with the Skin & Mucosa: If contacted by liquid ammonia, the body area affected should be immediately flooded with water. If no safety shower is available, utilize any available water source. Water will have the effect of thawing out clothing which may be frozen to the skin. Such clothing should be removed and flooding of the skin with water continued for at least 15 minutes. Obtain medical attention promptly. In Contact with the Eyes: If contacted by ammonia, the eyes must be flooded with copious quantities of clean water. Speed is essential. If contact lenses are worn, they must be removed; otherwise ammonia may be trapped underneath causing a severe burn. In isolated areas, water in a squeeze bottle which can be carried in the pocket is helpful for emergency irrigation purposes. An eye fountain should be used, but if not available, clean water from any source may be poured over the eyes. In any case, the eyelids MUST BE HELD OPEN and irrigation continued for at least 15 minutes. Repeat this procedure every ten minutes for an hour, each time irrigating for a period of five minutes until prompt medical attention can be obtained. Ingested: Material is a gas and ingestion is not a likely route of exposure. If conscious give 1-2 glasses of milk or water. Do not induce vomiting. Obtain medical attention. Emergency Medical Care: Pulmonary edema may be delayed. Injury may be more severe than would be indicated on early presentation. Medical conditions that may be aggravated by exposure include asthma, bronchitis, emphysema and other lung diseases and chronic nose, sinus or throat conditions. In the event of skin or eye contact, rapid and through flushing is essential. Fire & Explosion Data: Flash Point: Not applicable Auto ignition Temperature: Flammability Limits in Air UEL 25% LEL 16% Fire Extinguishing Media: C02, Dry Chemical, Water Spray Fire Fighting Procedures: Stop flow of gas. Use water to keep fire from exposed containers and to cool and protect personnel effecting the shut-off. Full protective equipment, including a self-contained breathing apparatus, should be worn in a fire involving the material. ACCIDENTAL RELEASE MEASURES Spill or Leak Measure: Stop leak if you can do so without risk. Keep unnecessary people away, isolate hazardous area and deny entry. Stay upwind, out of low areas, and ventilate closed spaces before entering. Evaluate the affected area to determine whether to evacuate or shelter-in-place by taping windows and doors, shutting off outside air intake (attic fans, etc.), and placing a wet towel or cloth over the face (if needed). Self-contained breathing apparatus (SCBA) and structural firefighter’s protective clothing will provide limited protection in outdoor releases for short-term exposure. Fully- MSDS Anhydrous Ammonia, C-grade Page 3/6 Jan. 26, 2016 encapsulating, vapour-protective clothing should be worn for spills and leaks with no fire. Use water spray to control vapours. Mixing of water and liquid ammonia will generate heat and ammonia vapours. CAUTION: a. Personal protective clothing may become brittle when exposed to liquid ammonia. b. Runoff from vapour control or dilution may cause environmental damage. Determining spill size: Generally, a small spill is one which involves a single, small package (i.e. up to a 55 gallon drum), small cylinder, or a small (non continuing) leak from a large container. Small Spill: a. Flush area with flooding amounts of water. b. First isolate 100 feet in all directions, and then protect persons downwind 0.1 miles during daylight and 0.2 miles at night. Large Spill: a. Dike far ahead of liquid spill for later disposal. b. Follow local emergency protocol for handling. c. First isolate 300 feet in all directions, and then protect persons down wind 0.2 miles during daylight and 0.5 miles at night. HANDLING AND STORAGE Handling Procedures and Equipment: Protect cylinders from physical damage. Do not store in basement locations. Keep out of sun and away from all direct heat sources. The material will attack copper, tin, zinc, and their alloys; some forms of rubber, plastics and coatings.

Storage

Requirements Store in cool, dry, well-ventilated area away from incompatibles. Secure cylinders Other Precautions: Protect cylinders from physical damage. Do not store in basement locations. Keep out of sun and away from all direct heat sources. The material will attack copper, tin, zinc, and their alloys; some forms of rubber, plastics and coatings. Locate safety shower and eyewash station close to chemical handling area. EXPOSURE CONTROLS, PERSONAL PROTECTION This information is based on industrial norms, please note any limits set by the manufacturer of your brand of safety gear. Odour Threshold: Less than 5ppm Respiratory Protection Requirements: <25 ppm: No protection required. 25 to 35 ppm: Protection required if the daily TWA is exceeded. 35 to 50 ppm: Protection required if exposed for more than 15 minutes. MSDS Anhydrous Ammonia, C-grade Page 4/6 Jan. 26, 2016 50 to 250 ppm: Minimum of air-purifying respirator equipped with ammonia canister(s) or cartridge(s). 250 to 300 ppm: Minimum of a full face air—purifying respirator equipped with ammonia canister(s) or cartridge(s). >300 ppm: A fresh air supply system must be used (i.e. positive pressure self contained breathing apparatus) Skin Protection Requirements: Skin protection is required for exposure to liquid, mist, and > 1000 ppm of ammonia gas or vapours. Neoprene or rubber gauntlet-type gloves; ammonia resistant clothing (overalls, jacket, and boots) or vapour suit, as required. Eye Protection Requirements: Use chemical (indirectly vented) goggles when there is a potential for contact with liquid or mist. A full-face shield may be worn over goggles for additional protection, but not a substitute for goggles. In areas where high concentrations (>250) of ammonia vapours may occur a SCBA may be required. Other Protective Equipment: Safety shower and eyewash fountain should be provided in the ammonia handling area. In agricultural distribution, provide easily accessible shower and / or at least 100 gallons of clean water in open top container (check regulations). When transporting, provide at least 5 gallons of accessible clean water and personal protective equipment. Engineering Controls: Adequate ventilation is required to keep ammonia concentrations below applicable standards when possible. Note to the Physician: Pneumonitis should be anticipated after inhalation or ingestion. If severe exposure is suspected, observe for 48-72 hours for delayed pulmonary edema.
