EMERGENCY OVERVIEW: Product Description: This gas mixture is colorless and has an odor of rotten eggs or sulfur. Health
Hazards: This gas mixture may cause adverse health effects due to the presence of Hydrogen Sulfide, Carbon Monoxide and Sulfur
Dioxide, which can reach exposure limits at the percentages in this mixture. Releases of this gas mixture may also produce oxygendeficient atmospheres (especially in confined spaces or other poorly-ventilated environments); individuals in such atmospheres may
be asphyxiated. The Carbon Monoxide component is a human reproductive toxin. Rapidly released gas can cause frostbite.
Flammability Hazards: This gas is non-flammable and will not support combustion. A moderate cylinder rupture hazard exists
when this gas mixture, which is under pressure, is subject to heat or flames. Reactivity Hazards: This gas mixture is not reactive.
Environmental Hazards: Release of this gas mixture is not expected to cause harm to the environment or to plants and animals,
except for possible frost and freezing from rapid release of a cylinder. Emergency Response Procedures: Emergency responders
must wear the proper personal protective equipment suitable for the situation to which they are responding. WARNING - If rescue
personnel need to enter an area suspected of having a low level of Oxygen, they should be equipped with Self-Contained Breathing
Apparatus (SCBA).

4. FIRST-AID MEASURES
PROTECTION OF FIRST AID RESPONDERS: RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO
WITHOUT ADEQUATE PERSONAL PROTECTIVE EQUIPMENT. At a minimum, Self-Contained Breathing Apparatus and
Chemically-Resistant Personal Protective equipment should be worn. Rescuers should be taken for medical attention, if necessary.
Only trained personnel should administer supplemental oxygen and/or cardio-pulmonary resuscitation, if necessary.
DESCRIPTION OF FIRST AID MEASURES: Contaminated individuals must be taken for medical attention if any adverse effects occur.
Take a copy of label and MSDS to health professional with victim.
Remove victim(s) to fresh air, as quickly as possible. 100% oxygen should be administered to victims of exposure to this gas mixture as
soon as possible. Only trained personnel should administer supplemental oxygen and/or cardio-pulmonary resuscitation, if necessary.
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).
INHALATION EXPOSURE: If inhaled, remove victim to fresh air. If necessary, use artificial respiration to support vital functions. Seek
immediate medical attention.
SKIN EXPOSURE: If this gas contaminates the skin, begin decontamination with running water. Minimum flushing is for 20 minutes.
Remove exposed or contaminated clothing, taking care not to contaminate eyes. Seek medical attention if adverse effect occurs after
flushing.
EYE EXPOSURE: If this gas enters the eyes, or if irritation of the eye develops after exposure, open victim's eyes while under gentle running
water. Use sufficient force to open eyelids. Have victim "roll" eyes. Minimum flushing is for 20 minutes. Administer anesthetic eye drops
after one minute of flushing if victim suffers from spasms to the eyes, in order to facilitate irrigation. Ice compresses should be applied when
this is not irritating to the victim. An ophthalmologist should be sought as soon as possible.
FROSTBITE EXPOSURE: If frostbite has occurred, remove any clothing that may restrict circulation to any frozen area. Do not rub frozen
parts as tissue damage may occur. As soon as practicable, place any affected area in warm water bath which has a temperature that
does not exceed 105°F (40°C). NEVER USE HOT WATER. NEVER USE DRY HEAT. If area of frostbite is extensive, and if possible,
remove clothing while showering with warm water. If warm water is not available, or is impractical to use, wrap the affected parts gently
in blankets. Alternatively, if the fingers or hands are frostbitten, place the affected area of the body in the armpit. Encourage victim to
gently exercise the affected part while being warmed. Frozen tissue is painless and appears waxy, with a possible yellow colo r.
Frozen tissue will become swollen, painful and prone to infection when thawed. If the frozen part of the body has been thawed by the
time medical attention has been obtained, cover the area with a dry sterile dressing and a large bulky protective covering.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Pre-existing dermatitis, other skin conditions, and respiratory disorders
may be aggravated by over-exposure to this gas.
INDICATION OF IMMEDIATE MEDICAL ATTENTION AND SPECIAL TREATMENT IF NEEDED: Treat symptoms and eliminate
exposure.

6. ACCIDENTAL RELEASE MEASURES
PERSONAL PRECAUTIONS AND EMERGENCY PROCEDURES: Evacuate immediate area. Uncontrolled releases should be
responded to by trained personnel using pre-planned procedures. Release may create an oxygen-deficient atmosphere in low-lying
areas or confined spaces.
PERSONAL PROTECTIVE EQUIPMENT: Proper protective equipment should be used.
All Releases: Minimum Personal Protective Equipment should be Level B: Self-Contained Breathing Apparatus. Note: chemically
protective clothing may provide little or no thermal protection against the hazard of frostbite. The atmosphere must at least 19.5
percent Oxygen before non-emergency personnel can be allowed in the area without Self-Contained Breathing Apparatus and fire
protection. If gas is leaking incidentally from the cylinder or its valve, contact your supplier.

6. ACCIDENTAL RELEASE MEASURES (Continued)
METHODS FOR CLEAN-UP AND CONTAINMENT:
All Releases: 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. 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 oxygen. Oxygen levels must be above 19.5% before nonemergency personnel are allowed to re-enter area. If leaking incidentally from the cylinder, contact your supplier.
ENVIRONMENTAL PRECAUTIONS: Avoid accidental release to the environment.
REFERENCE TO OTHER SECTIONS: See information in Section 8 (Exposure Controls – Personal Protection) and Section 13
(Disposal Considerations) for additional information.
7. HANDLING and USE
PRECAUTIONS FOR SAFE HANDLING: Follow all safety and work practices for handling of compressed gases safely. Compressed
gases can present significant safety hazards. As with all chemicals, wash hands after handling. Do not smoke or eat in work areas.
Use a check valve or other protective device in the discharge line to prevent hazardous backflow. Never tamper with pressure relief
valves and cylinders. Periodic inspections of process equipment by knowledgeable persons should be made to ensure that the
equipment is used appropriately and the system is kept in suitable operating condition. Emergency response equipment should be
available near the point of use. Be aware that and oxygen-deficient atmosphere can happen rapidly, causing dizziness or asphyxiation
without warning.
SPECIAL PRECAUTIONS FOR HANDLING GAS CYLINDERS: Compressed gases can present significant safety hazards. The
following rules are applicable to work situations in which cylinders are being used.
Before Use: Move cylinders with a suitable hand-truck. Do not drag, slide or roll cylinders. Do not drop cylinders or permit them to
strike each other. Secure cylinders firmly. Leave the valve protection cap (where provided) in-place until cylinder is ready for use.
During Use: Use designated CGA fittings and other support equipment. Do not use adapters. Do not heat cylinder by any means to
increase the discharge rate of the product from the cylinder. Do not use oils or grease on gas-handling fittings or equipment.
Immediately contact the supplier if there are any difficulties associated with operating cylinder valve. Never insert an object (e.g.,
wrench, screwdriver, pry bar, etc.) into valve cap openings. Doing so may damage valve, causing a leak to occur. Use an
adjustable strap wrench to remove over-tight or rusted caps. Never strike an arc, on a compressed gas cylinder or make a cylinder
part of and electric circuit.
After Use: Close main cylinder valve. Replace valve protection cap. Mark empty cylinders “EMPTY”.
CONDITIONS FOR SAFE STORAGE: Always store and handle compressed gas cylinders in accordance with Compressed Gas
Association, Inc. at www.cganet.com pamphlet CGA P-1, Safe Handling of Compressed Gases in Containers. Local regulations may
require specific equipment for storage and use. Cylinders should be stored upright and be firmly secured to prevent falling or being
knocked-over. Cylinders can be stored in the open, but in such cases, should be protected against extremes of weather and from the
dampness of the ground to prevent rusting. Cylinders should be stored in dry, well-ventilated areas away from sources of heat, ignition
and direct sunlight. Do not allow area where cylinders are stored to exceed 52°C (125°F). Store cylinders away from heavily trafficked
areas and emergency exits. Isolate from other non compatible chemicals (refer to Section 10, Stability and Reactivity). Store away from
process and production areas, away from elevators, building and room exits or main aisles leading to exits. Protect cylinders against
physical damage. Full and empty cylinders should be segregated. Use a first-in, first-out inventory systems to prevent full cylinders from
being stored for long periods of time.
SPECIFIC END USE(S): This product is for use in various industries. Follow all industry standards for use.
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
EXPOSURE LIMITS/CONTROL PARAMETERS:
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 poorlyventilated area, install automatic monitoring equipment to detect the levels of components and oxygen.

standards of Canada (including CSA Standard Z94.4-02 and CSA Standard Z94.3-02 and for foot protection Canadian CSA
Standard Z195-02, Protective Footwear), or standards of EU member states (including EN 529:2005 for respiratory PPE, CEN/TR
15419:2006 for hand protection, and CR 13464:1999 for face/eye protection). Please reference applicabl e regulations and
standards for relevant details.
RESPIRATORY PROTECTION: No special respiratory protection is required under normal circumstances of use. Maintain
component levels below 50% of the TLVs of components (see previous page) and oxygen levels above 19.5% in the workplace. Use
supplied air respiratory protection when component levels exceed 50% of the TLV, oxygen levels are below 19.5%, or during
emergency response to a release of this gas mixture. During an emergency situation, before entering the area, check the
concentration of components and Oxygen. If necessary, use only respiratory protection authorized in the appropriate country
regulations and standards. Oxygen levels below 19.5% are considered IDLH by OSHA. In such atmospheres, use of a f ullfacepiece pressure/demand SCBA or a full facepiece, supplied air respirator with auxiliary self-contained air supply is required under
OSHA. The following are NIOSH Respiratory Protective Equipment Guidelines for the toxic components of this gas mixture,

The following information is for this gas mixture.
FORM: Compressed gas.
COLOR: Colorless.
ODOR: Rotten egg or sulfurous. ODOR THRESHOLD: For Hydrogen Sulfide: 0.13 ppm; For Sulfur Dioxide: 0.33-5.0 ppm.
HOW TO DETECT THIS SUBSTANCE (identification/warning properties): The odor cannot be relied upon as a method of
identifying release of this gas mixture as continued low-level inhalation can cause olfactory fatigue, due to the presence of Hydrogen
Sulfide and the odor threshold of Sulfur Dioxide is of the same magnitude as the TLV. 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 also be
used for leak detection. The paper turns black in the presence of Hydrogen Sulfide. Cadmium solutions will turn yellow upon contact
with Hydrogen Sulfide.
10. STABILITY and REACTIVITY
REACTIVITY/CHEMICAL STABILITY: Normally stable in gaseous state.
DECOMPOSITION PRODUCTS: Combustion: Sulfur oxides, carbon oxides. Hydrolysis: None known.
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. Due to the presence of Hydrogen Sulfide, this gas mixture may
be incompatible with strong oxidizers. Hydrogen Sulfide is corrosive to most metals due to reaction with metals to form metal sulfides.
The Carbon Monoxide component is mildly corrosive to nickel and iron (especially at high temperature and pressure). The trace Sulfur
Dioxide component is incompatible with the following materials: chlorates, fluorine, interhalogens, sodium hydride, sodium, bases,
silver azide, barium peroxide, diethyl zinc, nitryl chloride, powdered metals, potassium, acrolein, lithium nitrate and prop ene,
monolithium acetylide-ammonia (lithium acetylene carbide diammino), cesium azide, metal oxides, metal acetylides, and carbide.
Although the Sulfur Dioxide component is in low concentration and significant reaction is not expected, caution should be used if contact
with this gas mixture and these materials can occur.
POSSIBILITY OF 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
SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE: The most
significant route of exposure to this gas mixture is via inhalation.
HAZARDOUS MATERIAL IDENTIFICATION SYSTEM
INHALATION: A significant hazard associated with releases of this product is the
potential for over-exposure to the Carbon Monoxide, Sulfur Dioxide and Hydrogen
Sulfide components of this gas mixture, which can reach exposure limits at the levels

HEALTH HAZARD
(BLUE)
present in the mixture. Inhalation of high concentrations of Hydrogen Sulfide can cause
dizziness, headache, and nausea. Exposure to higher concentrations can result in
respiratory arrest, coma, or unconsciousness. Exposure for more than 30 minutes at
concentrations of greater than 600 ppm has been fatal. Continuous inhalation of low
FLAMMABILITY HAZARD (RED) 0
concentrations may cause olfactory fatigue, so that the odor is no longer an effective
warning of the presence of Hydrogen Sulfide. Severe exposures which do not result in
death may cause long-term symptoms such as memory loss, paralysis of facial
muscles, or nerve tissue damage. In addition, inhalation exposure containing at or

more than the Threshold Limit Value (TLV) 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

available oxygen; through this replacement the body is deprived of required oxygen and
asphyxiation can occur. Since the affinity of Carbon Monoxide to hemoglobin is 200EYES

HANDS
BODY
300 times greater than that of oxygen, exposure to only a small amount can cause a
toxic effect. Carbon Monoxide exposures in excess of 50 ppm can produce a toxic

effect if breathed for a sufficient period of time. Inhalation of high concentrations of
Sulfur Dioxide can cause moderate to severe irritation to the respiratory tract or burns.
Effects may be delayed. A severe, short-term exposure may cause long-lasting For Routine Industrial Use and Handling Applications
respiratory effects, e.g. Reactive Airways Dysfunction (RADS).
Another significant health hazard associated with this gas mixture is when this gas mixture contains less than 19.5% Oxygen and is
released in a small, poorly-ventilated area (i.e. an enclosed or confined space). Under this circumstance, 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 overexposure, 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.
WARNING: Exposure to atmospheres containing 8-10% or less oxygen will bring about unconsciousness without warning
and so quickly that individuals cannot help or protect themselves. Lack of sufficient oxygen may cause serious injury or
death.
CONTACT WITH SKIN or EYES: The gas may be irritating to the skin. Contact with rapidly expanding gases (which are released
under high pressure) may cause frostbite. Due to presence Hydrogen Sulfide inflammation and irritation of the eyes can occur at very
low airborne concentration (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, there is an intense tearing, blurring of vision, and pain when looking at light.
Exposed individuals may see rings around bright lights. Most symptoms disappear when exposure ceases. However, in serious cases,
the eye can be permanently damaged. Due to presence Sulfur Dioxide inflammation and irritation of the eyes can occur at very low
airborne concentration (less than 10 ppm). 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: If inhalation occurs, toxic effects from Hydrogen Sulfide and Sulfur Dioxide may occur. Inhalation of high concentrations of
the mixture, as may occur in a confined space, may result in an oxygen-deficient atmosphere and asphyxiation. Contact with the
skin and eyes may be irritating. A sudden release of pressure from the cylinder may cause frostbite to exposed tissues.

11. TOXICOLOGICAL INFORMATION (Continued)
HEALTH EFFECTS OR RISKS FROM EXPOSURE (continued):
CHRONIC: Chronic low-level exposure to the eyes may result in damage to eyes from contact with Hydrogen Sulfide. Chronic low-level
exposure to the skin may cause dermatitis. Chronic exposure to oxygen-deficient atmospheres (below 18% oxygen in air) may affect
the heart and nervous system.
TARGET ORGANS: ACUTE: Respiratory system, central nervous system. CHRONIC: Skin, heart, nervous system, eyes.
TOXICITY DATA: Data are available for the Oxygen component, but since these data are from hyperbaric exposure to oxygen, which is
an unlikely exposure to this gas mixture, the data are not presented in this MSDS. No data are applicable to the main component,
Nitrogen, as it is a simple asphyxiant. The following are toxicological data available for the remaining components in 1% concentration
or greater. Due to the great amount of data available, only human data, LD50 Oral-Rat, Oral-Mouse, Skin-Rabbit, Skin-Rat, LC50
Inhalation-Rat, Inhalation-Mouse and irritation data are given. Contact Calgas for information on additional toxicity data.

CARCINOGENIC POTENTIAL OF COMPONENTS: The components of this gas mixture are listed by agencies tracking the
carcinogenic potential of chemical compounds, as follows:
Hydrogen Sulfide: EPA-I (Data are Inadequate for an Assessment of Human Carcinogenic Potential);
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: U.S. EPA, U.S. NTP, U.S. OSHA, U.S. NIOSH,
GERMAN MAK, IARC, or ACGIH; therefore, they are not considered to be, nor suspected to be, cancer-causing agents by these
agencies.
IRRITANCY OF PRODUCT: Due to the presence of Hydrogen Sulfide, skin contact may cause irritation. Due to the presence of Sulfur
Dioxide, eye contact may cause irritation. Contact with rapidly expanding gases can be irritating to exposed skin and eyes.
SENSITIZATION TO THE PRODUCT: No component of this product is known to cause human skin or respiratory sensitization.
REPRODUCTIVE TOXICITY INFORMATION: Listed below is information concerning the effects of the components this gas mixture on
the human reproductive system.
Mutagenicity: The components of this gas mixture are not reported to cause mutagenic effects in humans. In the one animal study
available, Carbon Monoxide gas increased chromosomal damage in blood cells of mice. The Sulfur Dioxide component is a
mutagen based on animal information. Positive results have also been reported in limited studies in humans. In animals, doserelated significant increases in bone marrow micronuclei, chromosome aberrations and DNA damage were obtained in wellconducted studies in mice exposed by inhalation. Positive results have also been obtained in cultured mammalian cells, bacteria
and yeast. Positive results (chromosome aberrations, sister chromatid exchanges, micronuclei) have been reported in cultured
human lymphocytes (white blood cells) taken from workers exposed to sulfur dioxide over several years. In the one animal study
available, Carbon Monoxide gas increased chromosomal damage in blood cells of mice.
Embryotoxicity: Severe acute exposures to the Carbon Monoxide component during pregnancy have caused adverse effects and
death of the fetus. In general, maternal symptoms are an indicator of the potential risk to the fetus since Carbon Monoxide i s
toxic to the mother before it becomes toxic to the fetus. No specific human information on effects of chronic exposure to Carbon
Monoxide during pregnancy. Animal studies suggest that repeated exposure to relatively high levels of Carbon Monoxide during
pregnancy may cause developmental effects without causing maternal toxicity.
Teratogenicity: Severe acute exposures to the Carbon Monoxide component during pregnancy have caused adverse effects and
death of the fetus. See above ‘Embryotoxicity’ for more information.
Reproductive Toxicity: The components of this gas mixture are not reported to cause reproductive effects in humans.

12. ECOLOGICAL INFORMATION
MOBILITY: Nitrogen is inert and does not present a hazard of mobility. Anhydrous Hydrogen Sulfide has a boiling point of 60.3°C at
1 atm. Consequently, when it is spilled onto soil, much will evaporate. However, since it is very soluble in water, the prese nce of
water in soil or falling as precipitation at the time of the spill may contribute to movement in the soil. If the soil surface is saturated
with moisture at the time of the spill as might be the case after a rainfall, the spill chemical will runoff and/or ev aporate away. If
released to soil, methane is expected to volatilize from soil (both moist and dry) based upon its vapor pressure and an estimated
Henry's Law constant of 0.66 atm-cu m/mole. Methane will have high mobility based upon an estimated Koc of 90. Utilization of
methane by soil microorganisms has been detected from soil samples. Sulfur dioxide uptake is dependent upon soil pH and
moisture content.
POTENTIAL TO BIOACCUMULATE: The Nitrogen component of this gas mixture will not bioaccumulate. The Hydrogen Sulfide
component does not have bioaccumulation or food chain contamination potential. An estimated BCF of 1 was calculated for
Methane, using a log Kow of 1.09 and a regression-derived equation. According to a classification scheme, this BCF suggests the
potential for bioconcentration in aquatic organisms is low.
PERSISTENCE AND BIODEGRADABILITY:
Persistence: Nitrogen is a natural element and presents no hazard of persistence. Methane, when released to air, a vapor
pressure of 4.7X10+5 mm Hg at 25°C indicates Methane will exist solely in the gas phase in the ambient atmosphere. Gas phase Methane will be very slowly degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals;
the half- life for this reaction in air is estimated to be about 6 years. If released into water, volatilization from water surfaces is
expected to be the dominant fate process based upon this compound's estimated Henry's Law constant. Estimated volatilization
half-lives for a model river and model lake are both 2 hrs. Methane is not expected to adsorb to suspended solids and sediment
based upon the estimated Koc. The lifetime of the Hydrogen Sulfide component is affected by ambient temperature and
other atmospheric variables including humidity, sunshine, and presence of other pollutants. Once released into the atmosphere,
Hydrogen Sulfide will behave like many other gaseous pollutants and be dispersed and eventually removed. Residence times in
the atmosphere range from about one day to more than 40 days, depending upon season, latitude, and atmospheric conditions.
The oxidation of Sulfur Dioxide to sulfuric acid and sulfates in the atmosphere is important with regard to air pollution studies.
Radicals, e.g. hydrogen monoxide, water, and carboxcylic acid, appear to be the principal species responsible for the
homogeneous oxidation of Sulfur Dioxide in the atmosphere, which occurs at rates as high as 4.0%/hr.
Biodegradation: Nitrogen does not biodegrade. Microorganisms in soil and water are involved in oxidation-reduction reactions
which oxidize the Hydrogen Sulfide component 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 high H2S
concentrations. The interactions of these organisms form part of the global sulfur cycle. The biodegradation half life of Methane
was estimated to range from 70 days to infinity based on gas exchange biodegradation experiments conducted in model
estuarine ecosystems. Hydrolysis is not expected to be an important environmental fate process since methane lacks functional
groups that hydrolyze under environmental conditions.
OZONE-DEPLETION POTENTIAL: Components are not Class I or Class II ozone depleting chemicals (40 CFR Part 82). A
photochemical model was used to quantify the sensitivity of the tropospheric oxidants Ozone (O 3) and Hydroxide Ion (OH ) to
changes in Methane (CH 4), Carbon Monoxide (CO), and Nitric Oxide (NO) emissions and to perturbations in climate and
stratospheric chemistry. In most cases, increased CH4 and CO emissions will suppress OH (negative coefficients) in increased O3
(positive coefficients) except in areas where NO and O3 influenced by pollution are sufficient to increased OH .In most regions, NO,
CO, and CH4 emission increase will suppress OH and increase O3, but these trends may be opposed by stratospheric O3 depletion
and climate change.
ECOTOXICITY: Due to the presence of Hydrogen Sulfide in this mixture, release near an aquatic environment may cause harm. The
following aquatic toxicity data are currently available for Hydrogen Sulfide:
