| III. Hazards Identification | |||||||||||||||||
| Colorless liquid with a pungent odor. Avoid contact with liquid and vapor. Not flammable. Mixes with water. Harmful to aquatic life in very low concentration. Stop discharge if possible. | |||||||||||||||||
| Potential Health Effects: | |||||||||||||||||
| Route of entry: Inhalation, skin contact, eye contact, ingestion Target organs: Eyes, skin and respiratory systems Eye contact: May be severely irritating upon liquid exposure, with irritation from fumes Skin contact: High concentrations can cause severe irritation and burns Inhalation: The gas can be suffocating and is irritant to the mucous membranes and lung tissue. Ingestion: Can cause vomiting, nausea and corrosive burns to the esophagus and stomach. The exact nature and intensity of toxic effects following ingestion of varying amounts of strong aqua ammonia solution (ex 20-30%) is unpredictable. The most accepted view is that any amount form one teaspoon or greater can be dangerous if ingested. | |||||||||||||||||
| IV. First Aid Measures | |||||||||||||||||
| Eye Contact: | Flush with large amounts of water for at least 15 minutes then immediately seek medical aid. | ||||||||||||||||
| Skin Contact: | Immediately flush with large quantities of water for at least 15 minutes while removing clothing. Seek immediate medical aid. | ||||||||||||||||
| Inhalation: | Remove from exposure. If breathing has stopped or is difficult, administer artificial respiration or oxygen as needed. Seek immediate medical aid. | ||||||||||||||||
| Ingestion: | Do not induce vomiting. Have victim drink large quantities of water if conscious. Immediately seek medical aid. Never give anything by mouth to an unconscious person. | ||||||||||||||||
| V. Fire Fighting Measures | |||||||||||||||||
| Flammability of the product: | 16-25% NH₃ in air (for labeling purposes, not DOT flammable gas). | ||||||||||||||||
| Extinguishing Media: | Water fog or spray for escaping ammonia gas. | ||||||||||||||||
| Special Fire Fighting Procedures: | The mixture will not burn but escaping gas can burn in the range of 16-25% NH₃ in air. Wear full protective clothing and self-contained breathing apparatus in the pressure demand mode. | ||||||||||||||||
| NFPA HAZARD CLASSIFICATION (Aqua): |
| ||||||||||||||||
| VI. Accidental Release Measures | |||||||||||||||||
| In US, federal regulations require that a release of 1,000 lb or more of ammonium hydroxide must be reported immediately to the National Response Center at (800) 424-8802, the SERC and the LEPC. In California, ALL releases must be reported to CUPA, state and local agencies. Additional state and local regulations may apply. SUGGESTED LOCAL ACTION: Releases will liberate irritating vapors. Spilled liquids should be contained and not washed into sewers or ground water. Prevent large quantities from contact with vegetation or waterways. Ammonium hydroxide is a regulated material and reporting of any release may be required. Any release of this material during the source of loading, transporting, unloading or temporary storage must be reported to the U.S. DOT as required by 49 CFR 171.15 and 171.16. | |||||||||||||||||
| VII. Handling and Storage | |||||||||||||||||
| Store in ventilated containers or pressure vessels away from heat. Open containers cautiously in case of pressure build up. Zinc, copper and copper alloys such as brass are rapidly corroded by ammonium hydroxide. | |||||||||||||||||
| VIII. Exposure Controls/Personal Protection | |||||||||||||||||
| Respiratory protection: | Approved by NIOSH/MSHA for ammonia must be used when exposure limits are exceeded. Whether chemical canister respirator or self-contained breathing apparatus is sufficient for effective respiratory protection depends on the type and magnitude of exposure. Skin protection: Rubber gloves and rubber or other types of approved protective clothing should be used to prevent skin contact. A face shield should be used for increased protection from contact with liquid or vapor. | ||||||||||||||||
| Eye protection: | Chemical splash goggles, approved for use with ammonia, must be worn to prevent eye contact with liquid or vapor. A face shield should be used for increased protection from contact with liquid. | ||||||||||||||||
| Ventilation: | Local positive pressure and/or exhaust ventilation should be used to reduce vapor concentrations in confined spaces. Ammonia vapor, being lighter than air, can be expected to dissipate to the upper atmosphere. Ammonia concentrations may also be reduced by the use of an appropriate absorbent or reactant material. | ||||||||||||||||

| X. Stability and Reactivity | |||||||||||||||||
Material generally considered stable. Heating above ambient temperature causes the vapor pressure of ammonia to increase rapidly. Incompatibility (materials to avoid): Strong acids. Aqua Ammonia reacts with bromine, chlorine, mercury, silver, silver solder, and hypochlorite (bleach) to form explosive compounds. Avoid use of metals containing copper or zinc. Heating and contact of vapors with very hot surfaces may form hydrogen. The decomposition temperature may be lowered to 575°F by contact with certain metals such as nickel. Hazardous Polymerization will not occur. | |||||||||||||||||
| XI. Toxicological Information | |||||||||||||||||
| Toxicity by ingestion: Grade 3; Oral Rat, LD⁵⁰ = 350 mg/kg. Ammonia is a strong alkali and readily damages all body tissues. Ammonia is not a cumulative metabolic poison. | |||||||||||||||||
| XII. Ecological Information | |||||||||||||||||
| Aquatic toxicity 6.25ppm 24hr/Trout/Lethal/Freshwater; 15ppm 48hr/Sunfish/TLm/Tap Water. | |||||||||||||||||
| XIII. Disposal Considerations | |||||||||||||||||
| Consult local, state or federal regulatory agencies for acceptable disposal procedures and disposal locations. Disposal in streams or sewers is generally contrary to federal, state, and local regulations. For Hazardous Waste Regulations call (800) 424-9346, The RCRA Hotline. | |||||||||||||||||
