3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: This product is a colorless gas which has a rotten-egg odor (due to the presence of
Hydrogen Sulfide). The odor cannot be relied on as an adequate warning of the presence of this product, because
olfactory fatigue occurs after over-exposure to Hydrogen Sulfide. Hydrogen Sulfide and Carbon Monoxide (another
component of this gas mixture) are toxic to humans in relatively low concentrations. Over-exposure to this gas
mixture can cause skin or eye irritation, nausea, dizziness, headaches, collapse, unconsciousness, coma, and
death. 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:
HAZARDOUS MATERIAL INFORMATION
The most significant route of over-exposure for this product is by

3. HAZARD IDENTIFICATION (Continued)
Inhalation over-exposures to atmospheres containing more than the Threshold Limit Value of Carbon Monoxide (25
ppm), another component of this gas mixture, 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:
CONCENTRATION OF
CARBON MONOXIDE OBSERVED EFFECT
All exposure levels: Over-exposure to Carbon Monoxide can be indicated by the lips and
fingernails turning bright red.
200 ppm: Slight symptoms (i.e. headache) after several hours of exposure.
400 ppm: Headache and discomfort experienced within 2-3 hours of exposure.
1,000 -2000 ppm: Within 30 minutes, slight palpitations of the heart occurs. Within 1.5
hours, there is a tendency to stagger.
200-2500 ppm: Within 2 hours, there is mental confusion, headaches, and nausea.
Unconsciousness within 30 minutes.
>2500 ppm: Potential for collapse and death before warning symptoms.
Additionally, if mixtures of this product contain less than 19.5% Oxygen and are 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 following 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.
SKIN and EYE CONTACT: Hydrogen Sulfide, a component of this gas mixture, may be irritating to the skin.
Inflammation and irritation of the eyes can occur at very low airborne concentration of Hydrogen Sulfide (less than 10
ppm). Exposure over several hours may result in 鈥済as eyes鈥? or 鈥渟ore eyes鈥? with symptoms of scratchiness,
irritation, tearing and burning. Above 50 ppm of Hydrogen Sulfide, there is an intense tearing, blurring of vision, and
pain when looking at light. Over-exposed individuals may see rings around bright lights. Most symptoms disappear
when exposure ceases. However, in serious cases, the eye can be permanently damaged.
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, Hydrogen Sulfide and Carbon Monoxide
(components of this gas mixture) are toxic to humans. Over-exposure to this gas mixture can cause nausea,
dizziness, headaches, collapse, unconsciousness, coma, and death. Due to the presence of Hydrogen Sulfide,
over-exposures to this gas mixture can also irritate the skin and eyes; severe eye contamination can result in
blindness.
CHRONIC: Severe over-exposures to Hydrogen Sulfide, a component of this gas mixture, which do not result in
death, may cause long-term symptoms such as memory loss, paralysis of facial muscles, or nerve tissue damage.
In serious cases of over-exposure, the eyes can be permanently damaged. Skin disorders and respiratory
conditions may be aggravated by repeated over-exposures to this gas product. Refer to Section 11 (Toxicology
Information) for additional information on the components of this product.
TARGET ORGANS: Respiratory system, blood system, central nervous system effects, cardiovascular system,
reproductive system, skin, eyes.

burst in the heat of the fire.
Explosion Sensitivity to Mechanical Impact: Not Sensitive.
Explosion Sensitivity to Static Discharge: Not Sensitive.
SPECIAL FIRE-FIGHTING PROCEDURES: Structural firefighters must wear Self-Contained Breathing Apparatus
and full protective equipment.
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 over-exposure to Hydrogen Sulfide and Carbon Monoxide, the toxic components of this
product, and other safety hazards related to the remaining components of this product, 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 Hydrogen Sulfide, Carbon Monoxide, and Oxygen. Hydrogen Sulfide and Carbon Monoxide
level must be below exposure level listed in Section 2 (Composition and Information on Ingredients) and Oxygen
levels must be above 19.5% before non-emergency personnel are allowed to re-enter area.
If leaking incidentally from the cylinder, contact your supplier.

APPEARANCE AND COLOR: This product is a colorless gas which has an rotten egg-like odor, due to the
presence of Hydrogen Sulfide.
HOW TO DETECT THIS SUBSTANCE (warning properties): Continuous inhalation of low concentrations of
Hydrogen Sulfide (a component of this gas mixture) may cause olfactory fatigue, so that there are no distinct
warning properties. In terms of leak detection, fittings and joints can be painted with a soap solution to detect leaks,
which will be indicated by a bubble formation. Wet lead acetate paper can be used for leak detection. The paper
turns black in the presence of Hydrogen Sulfide. Cadmium chloride solutions can also be used. Cadmium solutions
will turn yellow upon contact with Hydrogen Sulfide.
10. STABILITY and REACTIVITY
STABILITY: Normally stable in gaseous state.
DECOMPOSITION PRODUCTS: The thermal decomposition products of Methane include carbon oxides. The
decomposition products of Hydrogen Sulfide include water and sulfur 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 product). Lithium reacts slowly with Nitrogen at ambient temperatures. Components of this product
(Hydrogen Sulfide, Methane) are also incompatible with strong oxidizers (i.e. chlorine, bromine pentafluoride,
oxygen, oxygen difluoride, and nitrogen trifluoride). Carbon Monoxide is mildly corrosive to nickel and iron
(especially at high temperatures and pressures). Hydrogen Sulfide is corrosive to most metals, because it reacts
with these substances to form metal sulfides.
HAZARDOUS POLYMERIZATION: Will not occur.
CONDITIONS TO AVOID: Contact with incompatible materials. Cylinders exposed to high temperatures or direct
flame can rupture or burst.

11. TOXICOLOGICAL INFORMATION (Continued)
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, they are not considered to be, nor suspected to be, cancer-
causing agents by these agencies.
IRRITANCY OF PRODUCT: Hydrogen Sulfide, a component of this gas mixture, is irritating to the eyes, and may
be irritating to the skin.
SENSITIZATION OF PRODUCT: The components of this gas mixture are not known to be skin or respiratory
sensitizers.
REPRODUCTIVE TOXICITY INFORMATION: Listed below is information concerning the effects of this gas mixture
on the human reproductive system.
Mutagenicity: This gas mixture is not expected to cause mutagenic effects in humans.
Embryotoxicity: This gas mixture contains components that may cause embryotoxic effects in humans; however,
due to the small total amount of the components, embryotoxic effects are not expected to occur.
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. 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.
Reproductive Toxicity: This gas mixture is not expected 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.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Pre-existing respiratory conditions may be aggravated
by over-exposure to this product. Carbon Monoxide, a component of this gas mixture, can aggravate some diseases
of the cardiovascular system, such as coronary artery disease and angina pectoris. Because of the presence of
Hydrogen Sulfide, eye disorders or skin problems may be aggravated by over-exposure to this product.
RECOMMENDATIONS TO PHYSICIANS: Treat symptoms and eliminate over-exposure. 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. Be observant for initial signs of pulmonary edema in the event of severe inhalation over-exposures.
BIOLOGICAL EXPOSURE INDICES (BEIs): Biological Exposure Indices (BEIs) are applicable for this product, as

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. Air Liquide America 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.
