Section 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW Causes burns. Very toxic to aquatic organisms.
Potential Health Effects
Contact with liquid or vapor causes severe burns and possible irreversible eye damage.
Lachrymator (substance which increases the flow of tears).
Causes severe skin irritation. Causes skin burns. May cause deep, penetrating ulcers of the skin. Contact with the skin may cause staining, inflammation, and thickening of the skin.
Ingestion:
Harmful if swallowed. May cause severe and permanent damage to the digestive tract. Causes gastrointestinal tract burns. Causes throat constriction, vomiting, convulsions, and shock.
Inhalation:
Effects may be delayed. Causes severe irritation of upper respiratory tract with coughing, burns, breathing difficulty, and possible coma.
Prolonged inhalation may cause respiratory tract inflammation and lung damage. Prolonged or repeated exposure may cause corneal damage and the development of cataracts and glaucoma.
Section 4 - FIRST AID MEASURES
Eyes: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical aid immediately.
In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give anything by mouth to an unconscious person.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
After inhalation exposure, observe for 24 to 72 hours as pulmonary edema may be delayed.
Section 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
Approach fire from upwind to avoid hazardous vapors and toxic decomposition products. Ammonium hydroxide itself is non-combustible.
However concentrated ammonia solutions may give off ammonia vapours.
Ammonia gas is generally not considered a serious fire or explosion hazard because ammonia/air mixtures are difficult to ignite. A relatively high concentration of ammonia gas must be present in order for ignition to occur.
However, a large and intense energy source may cause ignition and/or explosion in a confined space.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Neutralize spill with a weak acid such as vinegar or acetic acid. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, observing precautions in the Protective Equipment section. Provide ventilation. Approach spill from upwind.
Section 7 - HANDLING and STORAGE
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Discard contaminated shoes. Do not breathe vapor. Use only with adequate ventilation.
Do not store in direct sunlight. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Corrosives area. Isolate from oxidizing materials and acids. Walls, floors, shelving, fittings, lighting and ventilation systems in storage area should be made from carbon steel or stainless steel which do not react with ammonium hydroxide.
Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other engineering controls to control airborne levels below recommended exposure limits. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.
Exposure Limits CAS# :
CAS# : United Kingdom, WEL - TWA: 25 ppm TWA (anhydrous); 18 mg/m3 TWA (anhydrous) United Kingdom, WEL - STEL: 35 ppm STEL (anhydrous); 25 mg/m3 STE (anhydrous) United States OSHA: 50 ppm TWA; 35 mg/m3 TWA Belgium - TWA: 20 ppm VLE; 14 mg/m3 VLE Belgium - STEL: 50 ppm VLE; 36 mg/m3 VLE France - VME: 25 ppm VME; 18 mg/m3 VME France - VLE: 50 ppm VLE; 36 mg/m3 VLE Germany: 50 ppm TWA; 35 mg/m3 TWA Japan: 25 ppm OEL; 17 mg/m3 OEL Malaysia: 25 ppm TWA; 17 mg/m3 TWA Netherlands: 50 ppm STEL; 36 mg/m3 STEL Netherlands: 20 ppm MAC; 14 mg/m3 MAC Russia: 20 mg/m3 TWA Spain: 20 ppm VLA-ED; 14 mg/m3 VLA-ED Spain: 50 ppm VLA-EC; 36 mg/m3 VLA-EC CAS# :
Personal Protective Equipment
Eyes: Wear chemical splash goggles and face shield.
Wear appropriate protective gloves to prevent skin exposure.
Wear appropriate protective clothing to prevent skin exposure.
Respirators:
Follow the OSHA respirator regulations found in 29 CFR
or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.

Therefore the flammable properties of ammonia apply.
Conditions to Avoid:
High temperatures, confined spaces, Ammonia solutions are corrosive to copper, zinc, aluminum and their alloys..
Incompatibilities with Other Materials:
Strong oxidizing agents, acids, acrolein, halogens, mercury, hypochlorite, silver nitrate, acrylic acid, dimethyl sulfate, silver oxide.
