3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: This gas mixture is a colorless gas with an irritating odor. Nitric Oxide (Nitrogen Monoxide), a component of this
gas mixture, can produce brownish Nitrogen Dioxide after reaction with oxygen. Nitric Oxide can produce adverse health effects in extremely
low concentrations (i.e. skin and eye irritation, dry throat); symptoms of over-exposure may not become apparent for up to 72 hours. Releases
of this gas mixture may produce oxygen-deficient atmospheres (especially in confined spaces or other poorly-ventilated environments);
individuals in such atmospheres may be asphyxiated.
SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE: The most significant route
HAZARDOUS MATERIAL IDENTIFICATION SYSTEM
of over-exposure for this gas mixture is by inhalation.
INHALATION: Due to the small size of an individual cylinder of this gas mixture, no unusual
health effects from over-exposure to the product are anticipated under routine circumstances of

(BLUE)
use. If this gas mixture is released in a small, poorly-ventilated area (i.e. an enclosed or HEALTH HAZARD
confined space), over-exposure to Nitric Oxide or an oxygen-deficient environment may occur.
Exposure to Nitric Oxide gas in low concentrations produces an irritating effect on the mucous
membranes of the eyes, nose, throat, and lungs. Acute exposure through inhalation may result FLAMMABILITY HAZARD

pertinent to higher concentrations of Nitric Oxide are provided to
give complete information on effects observed in humans after
over-exposures have occurred.
For Routine Industrial Use and Handling Applications
A typical Nitric Oxide over-exposure incident follows the course described in the next
paragraph:
After inhalation of a few breaths of Nitric Oxide, there is no immediate reaction, or only a very slight respiratory discomfo rt, headache,
dizziness, or lassitude. Within 5-8 hours of exposure (frequently after the employee has left the workplace and returned home), it is noticed
that the victim’s lips and ears have a blue (cyanotic) color. There then follows rapidly increasing symptoms of breathing difficulty, irregular
respiration, choking, dizziness, headache, increasing cyanosis, tightness in the chest, nausea, vomiting, lassitude, and palpitations. Left
untreated, death frequently occurs. Physical examination immediately following over-exposure reveals an accelerated respiratory rate,
decreased vital capacity, generally suppressed breathing sounds, low blood pressure, and a platelet count elevated by 10-100%.
Additionally, when this gas mixture is released in a small, poorly-ventilated area (i.e. an enclosed or confined space, an oxygen-deficient
environment may occur. Individuals breathing such an atmosphere may experience symptoms which include headaches, ringing in ears, dizziness,
drowsiness, unconsciousness, nausea, vomiting, and depression of all the senses. Under some circumstances of over-exposure, death may
occur. The effects associated with various levels of oxygen are as follows:
CONCENTRATION OF OXYGEN
OBSERVED EFFECT
12-16% Oxygen:
Breathing and pulse rate increased, muscular coordination slightly disturbed.
10-14% Oxygen:
Emotional upset, abnormal fatigue, disturbed respiration.
6-10% Oxygen:
Nausea, vomiting, collapse, or loss of consciousness.
Below 6%:
Convulsive movements, possible respiratory collapse, and death.

3. HAZARD IDENTIFICATION (Continued)
SKIN and EYE CONTACT: Prolonged exposure may cause potentially harmful amounts of Nitric Oxide, a component of this gas mixture, to
enter the body via absorption through the skin. The gas may be irritating to the skin, especially in a moist environment, for prolonged periods.
Symptoms of skin over-exposure may include scratchiness, pain, and redness. If Nitric Oxide contaminates the eyes, severe injury and swelling of
the eye tissue may occur.
HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. Over-exposure to this gas mixture may cause the following
health effects:
ACUTE: Due to the small size of the individual cylinder of this gas mixture, no unusual health effects from exposure to the product are anticipated
under routine circumstances of use. If this gas mixture is released in a small, poorly-ventilated area (i.e. an enclosed or confined space), overexposure to Nitric Oxide or an oxygen-deficient environment may occur. Over-exposures to Nitric Oxide, a component of this gas mixture, may
result in severe irritation and burns of eyes, skin, mucous membranes, and any other exposed tissue. If Nitric Oxide is inhaled, delayed pulmonary
damage and breathing difficulty may occur. Medical care is essential, as symptoms will rapidly worsen, possibly leading to death.
CHRONIC: Prolonged or repeated over-exposures may cause respiratory problems, bronchitis, hacking cough, nasal irritation and discharge,
increased fatigue, alteration in the senses of taste and smell. Repeated over exposures to Nitric Oxide can also result in dental erosion and gum
disorders.
TARGET ORGANS: ACUTE: Respiratory system, skin and eyes.
CHRONIC: Skin, respiratory system, teeth, heart, central nervous
system.
4. FIRST-AID MEASURES
RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO THIS GAS MIXTURE WITHOUT ADEQUATE PERSONAL
PROTECTIVE EQUIPMENT. At a minimum, Self-Contained Breathing Apparatus must be worn.
No unusual health effects are anticipated after exposure to this gas mixture, due to the small cylinder size. If any adverse symptom develops after
over-exposure to this gas mixture, remove victim(s) to fresh air as quickly as possible. Only trained personnel should administer supplemental
oxygen and/or cardio-pulmonary resuscitation if necessary. Victim(s) who experience any adverse effect after over-exposure to this gas mixture
must be taken for medical attention. Rescuers should be taken for medical attention if necessary. Take a copy of the label and the MSDS to
physician or other health professional with victim(s).
SKIN EXPOSURE: If irritation of the skin develops after exposure to this gas mixture, immediately begin decontamination with running water.
Minimum flushing is for 15 minutes. Remove exposed or contaminated clothing, taking care not to contaminate eyes. Victim must seek immediate
medical attention.
EYE EXPOSURE: If irritation of the eye develops after exposure to this gas mixture, open victim's eyes while under gentle running water. Use
sufficient force to open eyelids. Have victim "roll" eyes. Minimum flushing is for 15 minutes. Seek medical assistance immediately, preferably an
ophthalmologist.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Acute or chronic respiratory conditions, skin conditions, or eye disorders may be
aggravated by over-exposure to Nitric Oxide, a component of this gas mixture.
RECOMMENDATIONS TO PHYSICIANS: Administer oxygen as soon as possible, following exposure. If possible, have victim breathe as deeply
and rapidly as possible to help flush gas from the lungs. IN THE EVENT OF SEVERE OVER-EXPOSURES TO THIS GAS MIXTURE: Enforce
bed rest for 24 - 48 hours, whether or not symptoms have appeared. Start oxygen therapy at the first sign of symptoms. Provide medication to
reduce anxiety and dyspnea, as needed. Keep respiratory tract clear of mucous and exudate. Atropine, epinephrine, expectorants, emetics, most
sedatives and most cardiac glycosides are usually ineffective and possibly harmful. Surgical intervention to assist breathing may be necessary.
Respiratory infection should be controlled as soon as it is detected. Prednisone has been reported to be effective during recovery, in amounts of
3- 8 x 10-6 kg daily, in divided doses. If Nitric Oxide contaminates the eye, use an optic anesthetic to reduce pain. The victim should be promptly
examined by an ophthalmologist.

6. ACCIDENTAL RELEASE MEASURES
LEAK RESPONSE: Due to the small size and content of the cylinder, an accidental release of this gas mixture presents significantly less risk of
over-exposure to Nitric Oxide, the toxic component of this gas mixture, and other safety hazards related to the remaining components of this gas
mixture, than a similar release from a larger cylinder. However, as with any chemical release, extreme caution must be used during emergency
response procedures. In the event of a release in which the atmosphere is unknown, and in which other chemicals are potentially involved,
evacuate immediate area. Such releases should be responded to by trained personnel using pre -planned procedures. Proper protective
equipment should be used. In case of a leak, clear the affected area, protect people, and respond with trained personnel. Allow the gas mixture to
dissipate. If necessary, monitor the surrounding area (and the original area of the release) for levels of Nitric Oxide and Oxygen. The level of Nitric
Oxide must be at acceptable levels (see Section 2, Composition on 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.
If leaking incidentally from the cylinder, contact your supplier.
7. HANDLING and USE
WORK PRACTICES AND HYGIENE PRACTICES: Be aware of any signs of dizziness or fatigue; exposures to fatal concentrations of this gas
mixture could occur without any significant warning symptoms, due to over-exposure to Nitric Oxide or oxygen deficiency. All work practices should
minimize the release of Nitric Oxide. Eye wash stations/safety showers should be near areas where this gas mixture is used or stored. All work
operations should be monitored in such a way that emergency personnel can be immediately contacted in the event of a release. Do not attempt to
repair, adjust, or in any other way modify the cylinders containing this gas mixture. If there is a malfunction or another type of operational problem,
contact nearest distributor immediately.
STORAGE AND HANDLING PRACTICES: Cylinders should be firmly secured to prevent falling or being knocked-over. Cylinders must be
protected from the environment, and preferably kept at room temperature (approximately 21 C [70 F]). Cylinders should be stored in dry, wellventilated areas, away from sources of heat, ignition, and direct sunlight. Protect cylinders against physical damage.
Full and empty cylinders should be segregated. Use a first-in, first-out inventory system to prevent full containers from being stored for long
periods of time. These cylinders are not refillable. WARNING! Do not refill DOT 39 cylinders. To do so may cause personal injury or
property damage.
SPECIAL PRECAUTIONS FOR HANDLING GAS CYLINDERS: WARNING! Compressed gases can present significant safety hazards. During
cylinder use, use equipment designed for these specific cylinders. Ensure all lines and equipment are rated for proper service pressure.
PROTECTIVE PRACTICES DURING MAINTENANCE OF CONTAMINATED EQUIPMENT: Follow practices indicated in Section 6 (Accidental
Release Measures). Make certain that application equipment is locked and tagged-out safely. Always use product in areas where adequate
ventilation is provided.

12. ECOLOGICAL INFORMATION
ENVIRONMENTAL STABILITY: The gas will be dissipated rapidly in well-ventilated areas. Complex reactions of Nitric Oxide, a component of this
gas mixture, occur in the atmosphere, which contribute to air pollution. The following environmental data are applicable to the components of
this gas mixture.
NITRIC OXIDE:
Nitric Oxide is converted spontaneously in air to nitrogen dioxide, hence some of latter gas is invariably present whenever Nitric Oxide is found in air.
At concentrations below 50 ppm, this reaction is slow. At higher concentration this reaction may occur when only quantities of nitrogen dioxide are
present. Photochemical air pollution arises from a series of atmospheric reactions. The main components are ozone, oxides of nitrogen (such as
Nitric Oxide), aldehydes, peroxyacetyl nitrates, and hydrocarbons. Nitric Oxide can enter into the chemical reactions that lead to formation of
photochemical smog.
NITROGEN: Water Solubility = 2.4 volumes Nitrogen/100 volumes water at 0C. 16 volumes Nitrogen/100 volumes water at 20C.
EFFECT OF MATERIAL ON PLANTS or ANIMALS: Due to the presence of Nitric Oxide in this gas mixture, over-exposed animals would develop
respiratory system damage, as well as skin and eye disorders. Because Nitric Oxide produces corrosive solutions upon contact with moisture,
plants may be damaged or destroyed.
EFFECT OF CHEMICAL ON AQUATIC LIFE: Nitric Oxide can react with water or moisture to generate soluble nitrogen dioxide and other
corrosive nitrogen oxide compounds. If a release this gas mixture occurs near a body water, the release may be harmful or fatal to fish and other
aquatic life. The following are aquatic toxicity data for the Nitric Oxide component of this gas mixture.

16. OTHER INFORMATION
INFORMATION ABOUT DOT-39 NRC (Non-Refillable Cylinder) PRODUCTS
DOT 39 cylinders ship as hazardous materials when full. Once the cylinders are relieved of pressure (empty) they are not cons idered
hazardous material or waste. Residual gas in this type of cylinder is not an issue because toxic gas mixtures are prohibited. Calibration gas
mixtures typically packaged in these cylinders are Nonflammable n.o.s., UN 1956. A small percentage of calibration gases pack aged in DOT
39 cylinders are flammable or oxidizing gas mixtures.
For disposal of used DOT-39 cylinders, it is acceptable to place them in a landfill if local laws permit. Their disposal is no different than that
employed with other DOT containers such as spray paint cans, household aerosols, or disposable cylinders of propane (for camping, torch
etc.). When feasible, we recommended recycling for scrap metal content. CALGAZ will do this for any customer that wishes to return
cylinders to us prepaid. All that is required is a phone call to make arrangements so we may anticipate arrival. Scrapping cylinders involves
some preparation before the metal dealer may accept them. We perform this operation as a service to valued customers who want to
participate.
MIXTURES: When two or more gases or liquefied gases are mixed, their hazardous properties may combine to create additional, unexpected
hazards. Obtain and evaluate the safety information for each component before you produce the mixture. Consult an Industrial Hygienist or
other trained person when you make your safety evaluation of the end product. Remember, gases and li quids have properties which can
cause serious injury or death.
