3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: This gas mixture is colorless and has a mild to strong and suffocating Ammonia
odor (depending of level of Ammonia). The Ammonia component of this gas mixture can be extremely
irritating or corrosive at levels possible in this mixture. When the level of Ammonia is at lower levels (less than
1%), irritation of the eyes, skin and respiratory system may occur. When this gas mixture contains a higher
level of Ammonia is at higher levels (greater than 1%), over-exposures to this gas mixture may result in
severe irritation to the eyes, skin, mucous membranes, and other exposed tissue. Delayed pulmonary
damage and breathing difficulty may occur. Severe over-exposures can be fatal. This gas mixture is not
flammable or reactive. Persons who respond to releases of this product must protect themselves from
inhalation of the mixture, especially in areas which are downwind of the release. Extreme caution must be
used when responding to releases. Emergency responders must wear appropriate personal protective
equipment for the situation to which they are responding.
SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE: The most significant route of over-exposure
for this product is by inhalation.
INHALATION: The Ammonia component of this gas mixture can be extremely irritating or corrosive. At
lower Ammonia concentration levels, this gas mixture may irritate the lungs and throat. When Ammonia
levels are higher, inhalation over-exposures to this gas mixture may result in severe irritation and burns
of mucous membranes, throat and lungs. Delayed pulmonary damage and breathing difficulty may also
occur. Severe inhalation over-exposures can be fatal.
As a result of severe over-exposures to this gas mixture, permanent lung injury may occur.
Prolonged or repeated over-exposures to this gas mixture may cause impaired lung function,
bronchitis, or emphysema.
Note: symptoms can develop after over-exposure to concentrations of Ammonia in ranges which exist
in this gas mixture. The onset of the symptoms of pulmonary edema can be delayed for hours or
days after the exposure.

This level of exposure may result in rapid death due to suffocation or
fluid in the lungs. Exposure to concentrations in excess of 5000 ppm
may cause laryngeal spasms, resulting in death.
NOTE:
This gas mixture contains 1-500 ppm Ammonia. Data pertinent to
higher concentrations of Ammonia are provided to give complete
information on effects observed in humans after over-exposures
have occurred.
CONTACT WITH SKIN or EYES: When Ammonia levels are low, this gas mixture may be irritating to the
skin. When Ammonia levels are higher in the mixture, severe irritation of the skin may occur. When this
mixture contains low levels of Ammonia (less than 1%) contact of this gas with the eyes, will cause
watering, pain and irritation. Repeated, low level skin contact may result in dermatitis (dry, red, itchy
skin). When the Ammonia is at concentration, contact with the eyes may cause severe injury and
swelling of the eye tissue. Temporary vision impairment or permanent damage or blindness may occur.
Contact with rapidly expanding gases (which are released under high pressure) may cause frostbite.
SKIN ABSORPTION: Skin absorption is a significant route of exposure for Ammonia following prolonged
low-level exposure.

5. FIRE-FIGHTING MEASURES (Continued)
SPECIAL FIRE-FIGHTING PROCEDURES: Incipient fire responders should wear eye protection. Structural
fire fighters must wear Self-Contained Breathing Apparatus and full protective equipment. Use a water
spray or fog to reduce or direct vapors. Do not direct a water spray at the source of a release. Water spray
should be used with care. Approach fire from an upwind direction, to prevent over-exposure to this gas
mixture. If this product is involved in a fire, fire run-off water should be contained to prevent possible
environmental damage.
6. ACCIDENTAL RELEASE MEASURES
LEAK RESPONSE: Uncontrolled releases should be responded to by trained personnel using pre-planned
procedures. Proper protective equipment should be used In the event of a significant release from a single
cylinder. Call CHEMTREC (1-800-424-9300) for emergency assistance. Or if in Canada, call CANUTEC
(613-996-6666).
Attempt to close the main source valve prior to entering the area. If this does not stop the release (or if it is
not possible to reach the valve), allow the gas to release in-place or remove it to a safe area and allow the
gas to be released there. Monitor the surrounding area for the presence of Ammonia, and oxygen. The level
of must be below those listed in Section 2 (Composition and Information on Ingredients) and the atmosphere
must have at least 19.5 percent oxygen before personnel can be allowed in the area without Self-Contained
Breathing Apparatus.
7. HANDLING and USE
WORK PRACTICES AND HYGIENE PRACTICES
Do not eat or drink while handling chemicals.
Be aware of all potential exposure symptoms; exposures to fatal concentrations of this product could occur
without any significant warning symptoms.
All work operations should be monitored in such a way that emergency personnel can be immediately
contacted in the event of a release.
Workers who handle this gas mixture should wear protective clothing, as listed in Section 8 (Exposure
Controls and Personal Protection).
Instant-acting showers should be available in the event of an emergency.
Eye-wash fountains or similar equipment should be available for eye irrigation.
If ventilation controls are not adequate to control exposure to this gas mixture, proper respiratory
protection equipment should be provided and workers using such equipment should be carefully
trained in its operation and limitations.
Precautions must always be taken to prevent suck-back of foreign materials into the cylinder by using a
check-valve, or vacuum break, since suck-back may cause dangerous pressure changes within the
cylinder.
STORAGE AND HANDLING PRACTICES: Cylinders should be stored upright and be firmly secured to
prevent falling or being knocked-over. Cylinders can be stored in the open, but in such cases, should be
protected against extremes of weather and from the dampness of the ground to prevent rusting. Cylinders
should be stored in dry, well-ventilated areas away from sources of heat or ignition. Do not allow area where
cylinders are stored to exceed 52°C (125°F).
SPECIAL PRECAUTIONS FOR HANDLING GAS CYLINDERS: Compressed gases can present significant
safety hazards. The following rules are applicable to work situations in which cylinders are being used.
Before Use: Move cylinders with a suitable hand-truck. Do not drag, slide or roll cylinders. Do not drop
cylinders or permit them to strike each other. Secure cylinders firmly. Leave the valve protection cap
(where provided) in-place until cylinder is ready for use.
During Use: Use designated CGA fittings and other support equipment. Do not use adapters. Do not use
oils or grease on gas-handling fittings or equipment. Immediately contact the supplier if there are any
difficulties associated with operating the cylinder valve. Never insert an object (e.g wrench, screwdriver,
pry bar, etc.) into valve cap openings. Doing so may damage the valve, causing a leak to occur. Use an
adjustable strap wrench to remove over-tight or rusted caps. Never strike an arc, on a compressed gas
cylinder or make a cylinder part of and electric circuit.

empty. Mark empty cylinders “EMPTY”.
PROTECTIVE PRACTICES DURING MAINTENANCE OF CONTAMINATED EQUIPMENT: Refer to current
CGA Guidelines for information on protective practices during maintenance of contaminated equipment.
8. EXPOSURE CONTROLS - PERSONAL PROTECTION
VENTILATION AND ENGINEERING CONTROLS: Use with adequate ventilation to ensure compliance with
exposure limits described in Section 2 (Composition and Information on Ingredients). Local exhaust
ventilation is preferred, because it prevents dispersion of this gas mixture into the work place by eliminating it
at its source. If appropriate, install automatic monitoring equipment to detect the level of Ammonia, and
Oxygen. Eye wash stations/safety showers should be near areas where this product is used or stored.
RESPIRATORY PROTECTION: Maintain the level of Ammonia below those listed in Section 2 (Composition
and Information on Ingredients) and oxygen levels above 19.5% in the workplace. If necessary, use only
respiratory protection authorized in the U.S. Federal OSHA Respiratory Protection Standard (29 CFR
1910.134), or equivalent U.S. State standards and Canadian CSA Standard Z94.4-93. Oxygen levels below
19.5% are considered IDLH by OSHA. In such atmospheres, use of a full-facepiece pressure/demand
SCBA or a full facepiece, supplied air respirator with auxiliary self-contained air supply is required under
OSHA’s Respiratory Protection Standard (1910.134-1998). The following are NIOSH respiratory guidelines
for Ammonia.
