3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: This gas mixture is colorless and has a slight sulfur-like odor (due to the presence of Sulfur Dioxide). The Carbon
Monoxide component of this gas mixture, is a chemical asphyxiant and can produce significant, adverse health effects at relatively low
concentrations. Depending on the duration and concentration of Carbon Monoxide, over-exposure to this gas mixture may cause nausea,
dizziness, headaches, and collapse. Sulfur Dioxide can also produce adverse health effects in extremely low concentrations (i.e. skin and eye
irritation, dry throat, lung damage). Additionally, releases of this gas mixture 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 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 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 gas mixture is released in a small, poorly-ventilated area (i.e. an enclosed or confined space), symptoms which may develop include the

OBSERVED EFFECT
1 ppm (1-6 hr duration):
Reversible decrease in lung function.
5 ppm (10-30 min duration):
Constriction of bronchiole tubes.
8 ppm (20 min duration):
Reddening of the throat and mild nose and throat irritation.
20 ppm:
For most persons exposed, this level is objectionably irritating.
500 ppm:
At this level, Sulfur Dioxide is so objectionable, that it is difficult to inhale a single deep breath without
irritation.
Additionally, releases of this gas mixture may produce oxygen-deficient atmospheres (especially in small, confined spaces or other poorly-ventilated
environments); individuals in such atmospheres may be asphyxiated. 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:
OBSERVED EFFECT
CONCENTRATION OF OXYGEN
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.
SKIN and EYE CONTACT: Due to the presence of Sulfur Dioxide, this gas mixture may be irritating to the skin (especially in a moist environment).
Sulfur Dioxide may react with moisture on the skin to produce acidic solutions containing sulfurous acid. Symptoms of skin over-exposure may
include scratchiness, pain, and redness. If this gas mixture contaminates the eyes, damage to eye tissue will result in pain, inflammation, and
potentially, blindness.
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. However, the Carbon Monoxide 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. Under certain circumstances, over-exposure to this gas may be fatal. Another potential health hazard associated with this gas mixture is
the potential for over-exposure to Sulfur Dioxide, which can cause irritation and damage to the respiratory system, the skin, and eyes. Sulfur
Dioxide may react with moisture on the skin to produce sulfurous acid; contact with the acid can produce scratchiness, pain, and redness of
contaminated areas. Depending on the duration of over-exposure, contact with eye tissue may result in pain, inflammation, and blindness.
Symptoms of oxygen deficiency include respiratory difficulty, ringing in ears, headaches, shortness of breath, wheezing, headache, dizziness,
indigestion, nausea, unconsciousness, and death. The skin of a victim of over-exposure may have a blue color.
CHRONIC: Prolonged or repeated over-exposures to Sulfur Dioxide, a component of this gas mixture, 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 Sulfur
Dioxide can also result in dental erosion and gum disorders. Propane (another component of this gas mixture) can cause sensitization of the heart
to epinephrine, based on animal tests. Refer to Section 11 (Toxicology Information) for additional data on this gas mixture’s components. Chronic
exposure to oxygen-deficient atmospheres (below 18% oxygen in air) may affect the heart and nervous system.
TARGET ORGANS: ACUTE: Respiratory system, blood system, skin and eyes. CHRONIC: Cardiovascular system, heart, reproductive system,
teeth, skin, and eyes.

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: Pre-existing respiratory conditions may be aggravated by over-exposure to this gas
mixture. Carbon Monoxide, a component of this gas mixture, can aggravate some diseases of the cardiovascular system, such as coronary artery
disease and angina pectoris. Additionally, due to the presence of Sulfur Dioxide, skin, eye and dental conditions may be aggravated by overexposures to this gas mixture.
RECOMMENDATIONS TO PHYSICIANS: Treat symptoms and eliminate over-exposure. If necessary, the use of 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. Additionally, be observant for the signs of pulmonary edema
(due to the presence of Sulfur Dioxide).

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-exposures to Carbon Monoxide and Sulfur Dioxide and exposure to 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 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.
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, Carbon Monoxide, and Sulfur
Dioxide. Carbon Monoxide and Sulfur Dioxide levels 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 observant for the odor of sulfur; this odor is indicative of a potential over-exposure to this
gas mixture. Employees should also be aware of any signs of dizziness or fatigue; exposures to fatal concentrations of Carbon Monoxide could
occur rapidly. Do not attempt to repair, adjust, or in any other way modify the cylinders of mixtures containing Carbon Monoxide or Sulfur Dioxide. 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 gas mixture in well-ventilated areas. If this gas mixture is used in a poorly-ventilated area,
install automatic monitoring equipment to detect the levels of Carbon Monoxide, Sulfur Dioxide, and oxygen.
RESPIRATORY PROTECTION: No special respiratory protection is required under normal circumstances of use. Use supplied air respiratory
protection if Carbon Monoxide and Sulfur Dioxide levels exceed limits given in Section 2 (Composition Information on Ingredients) and oxygen
levels are below 19.5% or unknown during emergency response to a release of this gas mixture. If respiratory protection is needed, use only
protection authorized in the U.S. Federal OSHA Standard (29 CFR 1910.134), applicable U.S. State regulations, or the Canadian CSA Standard
Z94.4-93 and applicable standards of Canadian Provinces. 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). If respiratory protection is needed, use only protection authorized in the U.S. Federal
OSHA Standard (29 CFR 1910.134), applicable U.S. State regulations, or the Canadian CSA Standard Z94.4-93 and applicable standards of
Canadian Provinces. 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

detection, fittings and joints can be painted with a soap solution to detect leaks, which will e indicated by a bubble formation.
10. STABILITY and REACTIVITY
STABILITY: Normally stable in gaseous state.
DECOMPOSITION PRODUCTS: Sulfur Dioxide (a component of this gas mixture) will react with water or moist air to form sulfurous acid. The
thermal decomposition products of Methane and Propane (Components of this gas mixture) include carbon oxides. The other components of this
gas mixture do not decompose, per se, but can react with other compounds in the heat of a fire.
MATERIALS WITH WHICH SUBSTANCE IS INCOMPATIBLE: Titanium will burn in Nitrogen (the main component of this gas mixture). Lithium
reacts slowly with Nitrogen at ambient temperatures. The Propane, Carbon Monoxide, Methane components are also incompatible with strong
oxidizers (i.e. chlorine, bromine pentafluoride, oxygen, oxygen difluoride, and nitrogen trifluoride). The Sulfur Dioxide component is not compatible
with the following materials: strong bases, strong oxidizers, powdered metals, metal oxides, interhalogens, metal acetylides, sodium hydride, silver
azide, cesium azide, fluorine, zinc, zinc compounds. Carbon Monoxide is mildly corrosive to nickel and iron (especially at high temperatures and
pressures).
HAZARDOUS POLYMERIZATION: Will not occur.
CONDITIONS TO AVOID: Contact with incompatible materials. Cylinders exposed to high temperatures or direct flame can rupture or burst.

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:
Oxygen is the vital element in the atmosphere in
which we live and breathe. The atmosphere
contains
approximately
21%
oxygen.
Toxicological data are available for Oxygen, but
due to the small cylinder size and subsequent
small total amount of Oxygen in this mixture, no
effects are anticipated.
PROPANE:
Skin Contact (Rabbit):
Several formulations
containing an isobutane-propane mixture have
been tested for skin irritation effects.
All
formulations contained less than 13% propane.
All of the formulations containing propane caused
only mild irritation.
SULFUR DIOXIDE:
Eye, rabbit = 6 ppm/4 hours/32 days; mild effects
Mutation in Microorganisms System Test = 10
mmol/L
DNA damage System Test (human, lymphocyte) =
5700 ppb
TCLo (inhalation, mouse) = 32 ppm/ 24 hours
(female 7-28 day post); reproductive effects.
TCLo (inhalation, mouse) = 25 ppm/7 hours (female
6-15 days post); teratogenic effects
TCLo (inhalation, mouse) = 500 ppm/5 minutes/30
weeks; equivocal tumorigenic data
LCLo (inhalation, human) = 1000 ppm/10 minutes;

LC50 (inhalation, mouse) = 3000 ppm/30 minutes
LCLo (inhalation, guinea pig) = 1039 ppm/24 hours
LCLo (inhalation, frog) = 1 pph/ 15 minute
EYE IRRITATION: Temporary clouding of eyes was seen in rabbits, guinea pigs, and mice exposed to 400 ppm for 4 hours. Very severe eye injury in
rabbits was produced by a 5-second exposure to a stream of pure sulfur dioxide.
SHORT-TERM INHALATION STUDIES: Most studies indicate that high concentrations of Sulfur Dioxide effect the mechanics of respiration. A doserelated narrowing of the bronchiole tubes leading to bronchio-constriction was seen in guinea pigs exposed to concentrations of 0,2-100 ppm for 1 hour.
Exposure of male mice for up to 72 hours to concentrations around 10 ppm produced nasal cavity injury (runny nose, ciliary loss, fluid accumulation, and
tissue death). The effects became more severe as exposure time increased.
LONG-TERM INHALATION STUDIES: Exposure to 5 ppm for 225 days produced pulmonary function changes in dogs. Increased swelling,
secretions, and reddening of the trachea, as well as decreased mucosal flow was seen in dogs intermittently exposed to 1 ppm for 12 months. There
was no apparent effect on pulmonary function. No adverse effects were seen in guinea pigs exposed for 22 hours day, 7 days a week, for 52 weeks to
concentrations of 0.13-5.72 ppm. No adverse effects were seen in monkeys exposed for 78 weeks to 0.14 - 1.28 ppm.

11. TOXICOLOGICAL INFORMATION (Continued)
SUSPECTED CANCER AGENT: The components of this gas mixture are listed by agencies tracking the carcinogenic potential of chemical
compounds, as follows:
SULFUR DIOXIDE: ACGIH TLV-A4 (Not Classifiable as a Human Carcinogen); IARC-3 (Unclassifiable as to Carcinogenicity in Humans)
The remaining 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: Due to the presence of Sulfur Dioxide, this gas mixture can be very irritating and potentially damaging to the skin,
eyes, and respiratory system, especially in the presence of moisture.
SENSITIZATION OF PRODUCT: The components of this gas mixture are not known to be skin or respiratory sensitizers. Based on animal tests,
the Propane component of this gas mixture may cause cardiac sensitization to epinephrine.
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. The Sulfur Dioxide component of this
gas mixture has produced mutagenic effects on specific animal tissues exposed to relatively large doses.
Embryotoxicity: The components of this gas mixture are not reported to cause embryotoxic effects in humans. Sulfur Dioxide has produced
embryotoxic effects during clinical studies on test animals exposed to relatively large doses.
Teratogenicity: The components of this gas mixture are not reported to cause teratogenic effects in humans due to the small cylinder size and
small total amount of all components. Carbon Monoxide, a 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. Sulfur Dioxide has produced teratogenic effects during clinical studies on test animals exposed to relatively large doses.
Reproductive Toxicity: The components of this gas mixture are not reported to 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 components of this gas mixture, as
follows:

12. ECOLOGICAL INFORMATION
ENVIRONMENTAL STABILITY: The components of this gas mixture occur naturally in the atmosphere. The gas will be dissipated rapidly in wellventilated areas Complex reactions of Sulfur Dioxide (a component of this gas mixture) occur in the atmosphere can contribute to air pollution. The
following environmental data are applicable to the components of this gas mixture.
CARBON MONOXIDE: Water solubility = 3.3 ml/100 cc at 0°C, 2.3 ml at 20°C.
NITROGEN: Water Solubility = 2.4 volumes Nitrogen/100 volumes water at 0°C; 1.6 volumes Nitrogen/100 volumes water at 20°C.
OXYGEN: Water Solubility = 1 volume Oxygen/32 volumes water at 20°C. Log Kow = -0.65
PROPANE: Log Kow = 2.38. Water Solubility = 62.4 ppm, 25°C. Propane is readily degraded by soil bacteria.
SULFUR DIOXIDE: Sulfur Dioxide is extremely stable to heat (up to 2000 °C). Complex reactions of Sulfur Dioxide occur in the atmosphere, producing
sulfates and other sulfur compounds which contribute to air pollution. Freshwater lakes and rivers, and the aquatic biota they support, are susceptible
to acidification from atmospheric sulfur. Soil adsorption is dependent on pH and moisture content.
EFFECT OF MATERIAL ON PLANTS or ANIMALS: No evidence is currently available on the effects of this gas mixture on plant and animal life.
Carbon Monoxide, a 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. : Due to the presence of Sulfur Dioxide in this gas mixture, over-exposed animals
could develop respiratory system damage, as well as skin and eye disorders. Because Sulfur Dioxide produces corrosive solutions upon contact
with moisture, plants may be damaged or destroyed.
EFFECT OF CHEMICAL ON AQUATIC LIFE: If a release this gas mixture occurs near a body water, the release may be harmful or fatal to fish
and other aquatic life. Sulfur Dioxide, a component of this gas mixture, hydrolyzes to sulfurous acid solution when in contact with water. Sulfurous
acid is very soluble in water, and even low concentrations of Sulfur Dioxide or sulfurous acid in water are detrimental to aquatic life. The presence
of more than a trace of Carbon Monoxide (another component of this gas mixture) is also a hazard to fish. The following aquatic toxicity data are
available for the components of this gas mixture.
CARBON MONOXIDE:
LD (sunfish) = 1.5 ppm/1-6 hours, fresh water.
SULFUR DIOXIDE:
16-19 ppm; lethal to Sunfish
10 ppm for 0.17 hour; Trout float helplessly
SULFUR DIOXIDE (Continued):
5 ppm; lethal to Trout
0.5 ppm for 1 hour; toxic to fish
1 ppm for 2 hours; lethal to Tench

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.
