accordance with the hazard criteria of the CPR and the MSDS contains all the information required by the CPR.
EMERGENCY OVERVIEW: This gas mixture 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 gas mixture, 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-ex posure to this gas mixture can cause skin or
eye irritation, nausea, dizziness, headaches, collapse, unconsciousness, coma, and death. 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 asphy x iated.
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. A potential health hazard associated with this gas mixture is the potential of inhalation of
Hydrogen Sulfide, a component of this gas mixture. Such over-exposures may occur if this gas
mixture is used in a confined space or other poorly-ventilated area. Over-exposures to Hydrogen
Sulfide can cause dizziness, headache, and nausea. Over-exposure to this gas could result in
respiratory arrest, coma, or unconsciousness, due to the presence of Hydrogen Sulfide.
Continuous inhalation of low concentrations of Hydrogen Sulfide may cause olfactory fatigue, so
that the odor is no longer an effective warning of the presence of this gas. A summary of exposure
concentrations and observed effects are as follows:
CONCENTRATION OF
HYDROGEN SULFIDE
0.3-30 ppm Odor is unpleasant.
50 ppm Eye irritation. Dryness and irritation of nose, throat.
Slightly higher than 50 ppm Irritation of the respiratory system.
100-150 ppm Temporary loss of smell.
200-250 ppm Headache, vomiting nausea. Prolonged exposure
300-500 Swifter onset of symptoms. Death occurs in 1-4 hours.
500 ppm Headache, excitement, staggering, and stomach ache after brief exposure. Death occurs within 0.5 - 1
> 600 ppm Rapid onset of unconsciousness, coma, death.
> 1000 ppm Immediate respiratory arrest.
NOTE: This gas mixture contains a maximum of 250 ppm Hydrogen Sulfide. The higher concentration values
here are presented to delineate the complete health effects which have been observed for humans after exposure to Hydrogen Sulfide.

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 gas mixture 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 gas mixture 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 “gas eyes” or
“sore eyes” 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 gas mixture, no unusual health effects from exposure to the product are anticipated
under routine circumstances of use. However the 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 the Hydrogen Sulfide 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 gas mixture. Chronic exposure to oxygen-deficient
atmospheres (below 18% oxygen in air) may affect the heart and nervous system.
TARGET ORGANS: ACUTE: Respiratory system, blood sy stem, central nervous sy stem effects, cardiovascular sy stem, skin, ey es. CHRONIC:
Neurological system, reproductive system, 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.
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).
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.
SKIN EXPOSURE: If irritation of the skin develops after exposure to this gas mixture, immediately
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. Because of the presence of Hydrogen Sulfide, eye disorders or skin problems may be aggravated by over-exposure
to this gas mixture.
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.

6. ACCIDENTAL RELEASE MEASURES (continued)
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.
7. HANDLING and USE
WORK PRACTICES AND HYGIENE PRACTICES: Be aware of any signs of dizziness or fatigue, especially if work is done in a poorly ventilated
area; exposures to fatal concentrations of this gas mixture could occur without any significant warning symptoms, due to olfactory fatigue or oxygen
deficiency. Do not attempt to repair, adjust, or in any other way modify cylinders containing a gas mixture with Hydrogen Sulfide or Carbon
Monoxide. If there is a malfunction or another type of operational problem, contact nearest distributor immediately. 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. All work practices should minimize releases of Hydrogen Sulfide and Carbon
Monoxide-containing gas mixtures.
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 Oxygen, Hydrogen Sulfide, and Carbon Monoxide.
RESPIRATORY PROTECTION: No special respiratory protection is required under normal circumstances of use. Use supplied air respiratory
protection if the levels of components exceeds exposure limits presented in Section 2 (Composition and Information of 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 19.16.33% 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 NIOSH respiratory protection recommendations for
Hydrogen Sulfide and Carbon Monoxide are provided for further information.
NIOSH/OSHA RECOMMENDATIONS FOR HYDROGEN SULFIDE CONCENTRA TIONS IN AIR:

APPEARA NCE AND COLOR: This gas mixture 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 this gas mixture may cause
olfactory fatigue, due to the presence of Hydrogen Sulfide, so the odor is not a good warning property of a release of this gas mixture. 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 gas mixture). Lithium
reacts slowly with Nitrogen at ambient temperatures. Components of this gas mixture (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 POLYMERIZA TION: Will not occur.
CONDITIONS TO AVOID: Contact with incompatible materials. Cylinders exposed to high temperatures or direct flame can rupture or burst.

IRRITANCY OF PRODUCT: 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
: The components of this gas mixture are not reported to cause mutagenic effects in humans.
REPRODUCTIVE TOXICITY INFORMATION (continued):
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. 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 to cause adverse reproductive effects in humans.

Plant toxicity: Continuous fumigation of plants with 300 or 3000 ppb Hydrogen Sulfide caused leaf lesions, defoliation, and reduced growth with
severity of injury correlated to dose. At higher (3.25 and 5.03 ppm) Hydrogen Sulfide, significant reductions in leaf CO2 and water vapor
exchanges occurred, and stomatal openings were depressed. When Hydrogen Sulfide gas was applied to 29 species of green plants for 5
hours, young, rapidly elongating tissues were more sensitive to injury than older tissues. Symptoms included scorching of young shoots and

germination.
Persistence: Converts to elemental sulfur upon standing in water.
Major Species Threatened: Aquatic and animal life plants may be injured if exposed to 5 ppm in air over 24 hours.
Biodegradation: Microorganisms in soil and water are involved in oxidation-reduction reactions that oxidize hydrogen sulfide to elemental sulfur.
Members of the genera Beggiatoa, Thioploca, and Thiotrix function in transition zones between aerobic and anaerobic conditions where both
molecular oxygen and hydrogen sulfide are found. Also, some photosynthetic bacteria oxidize hydrogen sulfide to elemental sulfur. Members of
the families Chlorobiaceae and Chromatiaceae (purple sulfur bacteria) are obligate aerobes and are phototropic, and are found in waters with
S concentrations. The interactions of these organisms form part of the global sulfur cycle.

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.
