**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Irritating to eyes, respiratory system and skin.
Potential Health Effects
Eye:
Contact with liquid or vapor causes severe burns and possible
irreversible eye damage. Lachrymator (substance which increases the
flow of tears).
Skin:
Causes skin irritation.
Ingestion:
May cause irritation of the digestive tract. May be harmful if
swallowed.
Inhalation:
Effects may be delayed. Causes severe irritation of upper
respiratory tract with coughing, burns, breathing difficulty, and
possible coma.
Chronic:
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.
Skin:
In case of contact, immediately flush skin with plenty of water.
Remove contaminated clothing and shoes. Get medical aid. Wash
clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by
medical personnel. Never give anything by mouth to an unconscious
person. Get medical aid.
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 ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Keep container
tightly closed. Avoid breathing vapor. Do not get in eyes. Avoid
contact with skin and clothing.
Storage:
Do not store in direct sunlight. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. 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.

Personal Protective Equipment
Eyes:
Wear chemical splash goggles and face shield.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 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.
