3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: This product is a colorless, odorless gas. Carbon Monoxide, a component of this gas mixture, is a chemical asphyxiant and can
produce significant, adverse health effects at relatively low concentrations. Over-exposure to Carbon Monoxide can cause nausea, dizziness, headaches, and
collapse. Additionally, releases of this product may produce oxygen-deficient atmospheres (especially in small 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 of over-exposure for this product is by inhalation.
INHALATION: Due to the small size of an individual cylinder of this product, no unusual
health effects from over-exposure to the product are anticipated under routine
circumstances of use.
Inhalation over-exposures to atmospheres containing more than the Threshold Limit Value
of Carbon Monoxide (25 ppm) can result in serious health consequences. Carbon
Monoxide is classified as a chemical asphyxiant, producing a toxic action by combining
with the hemoglobin of the blood and replacing the available oxygen. Through this
replacement, the body is deprived of the required oxygen, and asphyxiation occurs.
Since the affinity of carbon monoxide for hemoglobin is about 200-300 times that of
oxygen, only a small amount of Carbon Monoxide will cause a toxic reaction to occur.
Carbon Monoxide exposures in excess of 50 ppm will produce symptoms of poisoning
if breathed for a sufficiently long time. If this product is released in a small, poorly
ventilated area (i.e. an enclosed or confined space), symptoms which may
develop include the following:

> 2500 ppm:
Potential for collapse and death before warning symptoms are produced.
Additionally, releases of this product may produce oxygen-deficient atmospheres (especially in small confined spaces or other poorly-ventilated
environments); individuals in such atmospheres may be asphyxiated.
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 product, no unusual health effects from exposure to the product are anticipated
under routine circumstances of use. However, Carbon Monoxide (a component of this gas mixture) is toxic to humans. Symptoms of Carbon
Monoxide poisoning can develop gradually, or can arise suddenly, depending on the concentration and duration of exposure. Lips and fingernails
will turn bright red, which is a significant sign of Carbon Monoxide over-exposure. Other symptoms of over-exposure can include respiratory
difficulty, headaches, shortness of breath, wheezing, headache, blurred vision, memory loss, dizziness, indigestion, nausea, unconsciousness, and
death.
CHRONIC: Chronic exposure to oxygen-deficient atmospheres (below 18% oxygen in air) may effect the heart and nervous system. Clinical
studies indicate that there is a relationship between exposure to Carbon Monoxide in specific occupations (i.e. fire-fighters, foundry workers) and an
increased incidence of cardiovascular problems. Carbon Monoxide is a reproductive toxin. Refer to Section 11 (Toxicological Information) of this
MSDS for further information.
TARGET ORGANS: ACUTE: Respiratory system, blood system. CHRONIC: Heart, cardiovascular system, central nervous system, reproductive
system.
4. FIRST-AID MEASURES
RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF OVER-EXPOSURE TO THIS PRODUCT WITHOUT
ADEQUATE PERSONAL PROTECTIVE EQUIPMENT. At a minimum, Self-Contained Breathing Apparatus and FireRetardant Personal Protective equipment should be worn. Adequate fire protection must be provided during rescue
situations. Victim(s) must be taken for medical attention. Rescuers should be taken for medical attention, if necessary. Take copy of label and
MSDS to physician or other health professional with victim(s).
No unusual health effects are anticipated after exposure to this product, due to the small cylinder size. If any adverse symptom develops after overexposure to this product, remove victim(s) to fresh air, as quickly as possible. Only Trained personnel should administer supplemental oxygen
and/or cardio-pulmonary resuscitation, if necessary. Only trained personnel should administer supplemental oxygen.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Pre-existing respiratory conditions may be aggravated by over-exposure to this
product. The Carbon Monoxide component of this gas mixture can aggravate some diseases of the cardiovascular system, such as coronary artery
disease and angina pectoris.
RECOMMENDATIONS TO PHYSICIANS: Treat symptoms and reduce over-exposure. Provide oxygen. Hyperbaric oxygen is the most efficient
antidote to Carbon Monoxide poisoning, the optimum range being 2-2.5 atm. A special mask, or, preferably, a compression chamber to utilize
oxygen at these pressures is required. Avoid administering stimulant drugs.

6. ACCIDENTAL RELEASE MEASURES
LEAK RESPONSE: Due to the small size and content of the cylinder, an accidental release of this product presents significantly less risk of an
oxygen deficient environment and other safety hazards 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 preplanned procedures. Proper protective equipment should be used. In case of a leak, clear the affected area, protect people, and respond with
trained personnel.
For emergency disposal, secure the cylinder and slowly discharge the gas to the atmosphere in a well-ventilated area or outdoors. Allow the gas
mixture to dissipate. If necessary, monitor the surrounding area (and the original area of the release) for oxygen and Carbon Monoxide. Carbon
Monoxide level must be below exposure level listed in Section 2 (Composition and Information on Ingredients) before non-emergency personnel
are allowed to re-enter area.
If leaking incidentally from the cylinder or its valve, 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 product
could occur without any significant warning symptoms, due to oxygen deficiency. Do not attempt to repair, adjust, or in any other way modify the
cylinders containing Carbon Monoxide. 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.
8. EXPOSURE CONTROLS - PERSONAL PROTECTION
VENTILATION AND ENGINEERING CONTROLS: No special ventilation systems or engineering controls are needed under normal
circumstances of use. As with all chemicals, use this product in well-ventilated areas. If this product is used in a poorly-ventilated area, install

11. TOXICOLOGICAL INFORMATION (continued)
HYDROGEN:
There are no specific toxicology data for Hydrogen. Hydrogen is a simple asphyxiant (SA), which acts to displace oxygen in the environment.
METHANE:
There are no specific toxicology data for Methane. Methane is a simple asphyxiant, which acts to displace oxygen in the environment.
NITROGEN:
There are no specific toxicology data for Nitrogen. Nitrogen is a simple
asphyxiant, which acts to displace oxygen in the environment.
OXYGEN:
The toxicity data for Oxygen are related to exposures in a hyperbaric environment and are not likely to occur in industrial exposure situations.
SUSPECTED CANCER AGENT: The components of this gas mixture are not found on the following lists: FEDERAL OSHA Z
LIST, NTP, CAL/OSHA, and IARC; therefore are not considered to be, nor suspected to be, cancer-causing agents by these
agencies.
IRRITANCY OF PRODUCT: Contact with rapidly expanding gases can be irritating to exposed skin and eyes.
SENSITIZATION OF PRODUCT: The components of this gas mixture are not sensitizers.
REPRODUCTIVE TOXICITY INFORMATION: Listed below is information concerning the effects of this gas mixture on the human
reproductive system.
Mutagenicity: The components of this gas mixture are not reported to cause mutagenic effects in humans.
Embryotoxicity: The components of this gas mixture are not reported to cause embryotoxic effects in humans.
Teratogenicity: This gas mixture is not expected to cause teratogenic effects in humans due to the small cylinder size and small
total amount of all components. The Carbon Monoxide component of this gas mixture, which exists up to 1%, can cause
teratogenic effects in humans. Severe exposure to Carbon Monoxide during pregnancy has caused adverse effects and the
death of the fetus. In general, maternal symptoms are an indicator of the potential risk to the fetus since Carbon Monoxide is
toxic to the mother before it is toxic to the fetus.
Reproductive Toxicity: The components of this gas mixture are not reported cause adverse reproductive effects in humans.
A mutagen is a chemical which causes permanent changes to genetic material (DNA) such that the changes will propagate
through generation lines. An embryotoxin is a chemical which causes damage to a developing embryo (i.e. within the first
eight weeks of pregnancy in humans), but the damage does not propagate across generational lines. A teratogen is a
chemical which causes damage to a developing fetus, but the damage does not propagate across generational lines. A
reproductive toxin is any substance which interferes in any way with the reproductive process.
BIOLOGICAL EXPOSURE INDICES (BEIs): Biological Exposure Indices (BEIs) have been determined for the Carbon Monoxide
component, as follows:
CHEMICAL DETERMINANT
CARBON MONOXIDE
• Carboxyhemoglobin in blood
• Carbon monoxide in end-exhaled air
SAMPLING TIME
BEI
• 3.5% of hemoglobin
• 20 ppm
• End of shift
• End of shift
12. ECOLOGICAL INFORMATION
ENVIRONMENTAL STABILITY: The components of this gas mixture occur naturally in the atmosphere. The gas will be
dissipated rapidly in well-ventilated areas.
EFFECT OF MATERIAL ON PLANTS or ANIMALS: No evidence is currently available on the effects of this gas mixture on plant
and animal life. The Carbon Monoxide component of this gas mixture can be deadly to exposed animal life, producing symptoms
similar to those experienced by humans. Carbon Monoxide may also be harmful to plant life.
EFFECT OF CHEMICAL ON AQUATIC LIFE: No evidence is currently available on this product’s effects on aquatic life. The
presence of more than a trace of the Carbon Monoxide component of this product is a hazard to fish.
13. DISPOSAL CONSIDERATIONS
PREPARING WASTES FOR DISPOSAL PREPARING WASTES FOR DISPOSAL: Waste disposal must be in accordance with

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
considered 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 packaged 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 liquids have properties which can cause serious injury or death.
