Potential Health Effects
----------------------------------
Inhalation:
Vapors and mists cause irritation to the respiratory tract. Higher concentrations can cause
burns, pulmonary edema and death. Brief exposure to 5000 ppm can be fatal.
Ingestion:
Toxic! May cause corrosion to the esophagus and stomach with perforation and peritonitis.
Symptoms may include pain in the mouth, chest, and abdomen, with coughing, vomiting
and collapse. Ingestion of as little as 3-4 mL may be fatal.
Skin Contact:
Causes irritation and burns to the skin.
Eye Contact:
Vapors cause irritation. Splashes cause severe pain, eye damage, and permanent blindness.
Chronic Exposure:
Repeated exposure may cause damage to the tissues of the mucous membranes, upper
respiratory tract, eyes and skin.
Aggravation of Pre-existing Conditions:
Persons with pre-existing eye disorders or impaired respiratory function may be more
susceptible to the effects of this material.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Call a physician immediately.
Ingestion:
If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never give
anything by mouth to an unconscious person. Get medical attention immediately.

AMMONIUM HYDROXIDE (10 - 35% NH3) Page 3 of 8
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes while removing
contaminated clothing and shoes. Call a physician, immediately. Wash clothing before
reuse.
Eye Contact:
Immediately flush eyes with gentle but large stream of water for at least 15 minutes, lifting
lower and upper eyelids occasionally. Call a physician immediately. Immediate action is
critical to minimize possibility of blindness.
5. Fire Fighting Measures
Fire:
Autoignition temperature: 651C (1204F)
Flammable limits in air % by volume:
lel: 16; uel: 25
Explosion:
Flammable vapors may accumulate in confined spaces.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire. Use water spray to blanket fire,
cool fire exposed containers, and to flush non-ignited spills or vapors away from fire.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained
breathing apparatus with full facepiece operated in the pressure demand or other positive
pressure mode.
6. Accidental Release Measures
Ventilate area of leak or spill. Keep unnecessary and unprotected people away from area of
spill. Wear appropriate personal protective equipment as specified in Section 8. Contain and
recover liquid when possible. Do not flush caustic residues to the sewer. Residues from
spills can be diluted with water, neutralized with dilute acid such as acetic, hydrochloric or
sulfuric. Absorb neutralized caustic residue on clay, vermiculite or other inert substance and
package in a suitable container for disposal.
US Regulations (CERCLA) require reporting spills and releases to soil, water and air in
excess of reportable quantities. The toll free number for the US Coast Guard National
Response Center is (800) 424-8802.
J. T. Baker NEUTRACIT?2 or BuCAIM?caustic neutralizers are recommended for spills
of this product.
7. Handling and Storage
http://www.jtbaker.com/msds/englishhtml/A5916.htm 11/16/05
AMMONIUM HYDROXIDE (10 - 35% NH3) Page 4 of 8
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against
physical damage. Separate from incompatibilities. Store below 25C. Protect from direct
sunlight. Containers of this material may be hazardous when empty since they retain
product residues (vapors, liquid); observe all warnings and precautions listed for the
product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
-OSHA Permissible Exposure Limit (PEL):
50 ppm (NH3)
-ACGIH Threshold Limit Value (TLV):
25 ppm (NH3) (TWA) 35 ppm (STEL)
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures
below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred
because it can control the emissions of the contaminant at its source, preventing dispersion
of it into the general work area. Please refer to the ACGIH document, Industrial
Ventilation, A Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded and engineering controls are not feasible, a full facepiece
respirator with an ammonia/methylamine cartridge may be worn up to 50 times the
exposure limit or the maximum use concentration specified by the appropriate regulatory
agency or respirator supplier, whichever is lowest. For emergencies or instances where the
exposure levels are not known, use a full-facepiece positive-pressure, air-supplied
respirator. WARNING: Air purifying respirators do not protect workers in oxygen-deficient
atmospheres.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls,
as appropriate, to prevent skin contact. Neoprene and nitrile rubber are recommended
materials. Polyvinyl alcohol is not recommended.
Eye Protection:
Use chemical safety goggles and/or full face shield where dusting or splashing of solutions
is possible. Maintain eye wash fountain and quick-drench facilities in work area.
