SECTION 3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: Product Description: This gas mixture is a non-flammable, colorless gas mixture with an odor
characteristic of Chlorine. Health Hazards: This gas mixture may cause adverse health effects, due to the presence of Chlorine,
which can reach exposure limits at the level present in this mixture. This gas mixture may be toxic by inhalation, skin and eye
contact and can cause moderate to severe irritation. Pure chlorine is a powerful caustic irritant to all tissues: while the dilute
concentration (250 ?900 ppm) of chlorine in this mixture significantly reduces exposure risk, releases of this product must be
responded to with care. Flammability Hazards: This gas mixture is not flammable. Reactivity Hazards: This gas mixture is not
reactive. Environmental Hazards: Release of this product to the environment may cause environmental harm. Emergency
Response Considerations: If rescue personnel need to enter an area suspected of having toxic levels of chlorine, they should be
equipped with Self-Contained Breathing Apparatus (SCBA).
HMIS RATINGS: HEALTH HAZARD: = 1; FLAMMABILITY HAZARD: = 0; PHYSICAL HAZARD: = 1
ROUTES OF ENTRY, SYMPTOMS OF ACUTE EXPOSURE: The most significant routes of over-exposure for this gas
are by inhalation, skin and eye contact. Symptoms of exposure by all routes of exposure may be delayed. Acute overexposure
to this material may cause the following health effects:
EYE CONTACT: Can cause irritation. Can cause serious injury to the eyes and possible burns, depending on
concentration and duration of exposure.
INGESTION: Not a likely route of industrial exposure.
INHALATION: Can cause irritation of the nose and throat upon minor inhalation exposure. Over-exposure to chlorine,
which is toxic at very low levels, can cause the following health effects: coughing, labored breathing, sore throat, and
potentially fatal lung disorders (chemical pneumonitis and pulmonary edema). Symptoms of acute inhalation exposure can
be delayed for hours.
Although high concentrations of this gas mixture can cause an oxygen-deficient environment, the toxic effects of Chlorine will
be a more significant hazard than oxygen deficiency.

SECTION 3. HAZARD IDENTIFICATION (Continued)
SKIN CONTACT: Can cause burns or dermatitis (red, cracked, irritated skin), depending upon concentration and
duration of exposure due to the presence of Chlorine in this gas mixture
ROUTES OF ENTRY, SYMPTOMS OF CHRONIC EXPOSURE:
ROUTE OF ENTRY: Inhalation, skin.
TARGET ORGANS: Respiratory system, olfactory system, skin.
SYMPTOMS: Persistent irritation may result from repeated exposures. Chronic exposure to relatively minor levels may
cause bronchitis, hacking cough, alteration of sense of smell, permanent loss of lung efficiency and emphysema.
Chronic inhalation can lead to erosion of the teeth. Repeated exposure to the skin may cause dermatitis.
MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE: Due to the presence of Chlorine, pre-existing
dermatitis, other skin conditions, and respiratory disorders may be aggravated by over-exposure to this gas mixture.
CARCINOGENICITY: The components of this gas mixture are not listed on the EPA, NIOSH, GERMAN MAK, OSHA, NTP, or
CAL/OSHA Carcinogenicity lists. Chlorine is listed by the ACGIH as TLV-A4 (Not Classifiable as a Human Carcinogen).
SECTION 4. FIRST AID MEASURES
EYE CONTACT: In case of contact, gently flush victim's eyes with water for minimum of 15 minutes. Administer anesthetic eye
drops after one minute of flushing if victim suffers from spasms to the eyes, in order to facilitate irrigation. Victim should consult an
ophthalmologist in the event of severe over-exposure.
INGESTION: Not a likely route of exposure for this gas mixture.
INHALATION: Remove victim(s) to fresh air, as quickly as possible. Trained personnel should administer supplemental oxygen
and/or cardio-pulmonary resuscitation, if necessary. In the event of severe, immediate effects or delayed symptoms, victim must
seek appropriate medical attention.
SKIN CONTACT: In case of skin contact, immediately flush area of exposure with copious amounts of water for minimum of 15
minutes. Remove exposed or contaminated clothing, taking care not to contaminate eyes. Victim should seek appropriate
medical attention if symptoms persist. Treat any symptoms of frost bite by gently warming affected area. DO NOT USE HOT
WATER.
NOTES TO PHYSICIANS: Administer oxygen. Treatment is symptomatic and supportive. Be observant for initial signs of
pulmonary edema.
For Inhalation Exposure: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious,
has severe pulmonary edema, or is in respiratory arrest. Early intubation at the first sign of upper airway obstruction may be
necessary. Positive-pressure ventilation techniques with a bag valve mask device may be beneficial. Monitor cardiac rhythm and
treat arrhythmias if necessary. Start an IV with D5W /SRP: "To keep open", minimal flow rate. Use lactated Ringer's if signs of
hypovolemia are present. Watch for signs of fluid overload. Consider drug therapy for pulmonary edema. Consider vasopressors
to treat hypotension without signs of hypovolemia. Use proparacaine hydrochloride to assist eye irrigation.

SECTION 6. ACCIDENTAL RELEASE MEASURES
STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED: In the event of a release of this product, operator
should close the material source if possible to do so safely. Evacuate immediate area. Only trained personnel wearing Self-
Contained Breathing Apparatus (SCBA) and chemically resistant suit should re-enter a contaminated area.
If leak is in user's gas handling equipment or system, close cylinder valve, and safely vent high pressure and purge with inert gas
before attempting repairs. Purge gas should be near atmospheric pressure before attempting repairs. If leak is from the cylinder,
cylinder valve or the valve pressure relief device (PRD), contact your supplier.
Prior to re-entry into area, monitoring must confirm that Chlorine is no longer present. Oxygen level should be above 19.5%.
Detection systems should be available.

SECTION 7. HANDLING AND 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.
STORAGE: Cylinders should be stored upright (with valve protection caps and valve outlet plugs in place) and firmly secured to
prevent falling or being knocked over. Cylinders should be stored in dry, well-ventilated areas. Protect from salt or other corrosive
materials. Storage should be away from heavily traveled areas, walkways, elevators, platform edges or other objects or situations
that could damage the cylinder wall. Do not store in a manner that will block emergency exits, fire extinguishers or other safety
equipment. Do not allow storage temperature to exceed 125癋 (52癈). Use a first-in, first-out inventory system to prevent full
containers from being stored for long periods of time. Store empty cylinders away from full cylinders. Consideration should be
taken to install leak detection and alarm equipment for storage areas. NOTE: Use only DOT or ASME code cylinders designed
for compressed gas storage. Cylinders must not be recharged except by or with the consent of owner.
HANDLING: Handle this gas mixture only in sealed and purged systems. Spectra Gases, Inc. strongly recommends that
this gas mixture only be handled in areas with good venting capabilities, preferably a gas handling cabinet. Monitoring may be
considered for areas in which this gas mixture is used. Any detection of chlorine should trigger immediate response and corrective
action.
Before using this gas, meticulous leak checking using inert gas is strongly recommended, particularly after new
connections are made. Before introduction of a chlorine mixture into a system, it should be purged with a dry, inert gas such as
helium or nitrogen. Chlorine-handling systems should be free of moisture, as chlorine can corrode some metals in the presence of
moisture. Prior to use, chlorine-handling equipment must be thoroughly cleaned, solvent-rinsed and dried. Due to corrosive
properties of chlorine only suitable materials should be used for construction; chrome and aluminum are not suitable. Cylinder
valves should be inspected regularly for physical damage or corrosion (apparent by discoloration or rust). Care should be taken to
inspect the following valve locations for corrosion: neck (where valve inserts into cylinder); bonnet nut (where handle attaches to
valve body). Close valve after each use and when empty.
Do not drag, roll, slide or drop cylinder. Use a suitable hand truck designed for cylinder movement. Never attempt to lift a cylinder
by its cap. Secure cylinders at all times while in use. Use a pressure regulator to safely discharge product from cylinder. Use a
check valve to prevent reverse flow into cylinder. After cylinder has been connected to properly purged process, open cylinder
valve slowly and carefully. If user experiences any difficulty operating cylinder valve, discontinue use and contact supplier. Never
insert an object (e.g., wrench, screwdriver, 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.
Do not heat cylinders by any means to increase the discharge rate of product from the cylinder. Never apply flame or localized
heat directly to any part of the cylinder. Cylinders should not be artificially cooled as certain types of steel undergo property
changes when cryogenically cooled, thus making the cylinder unstable.
PROTECTIVE PRACTICES DURING MAINTENANCE OF CONTAMINATED EQUIPMENT: Follow practices
indicated in Section 6 (Accidental Release Measures). Relieve pressure before attempting repairs.
SPECIAL PRECAUTIONS: Be aware of any signs of dizziness or fatigue; exposures to fatal concentrations of this material
could occur without any significant warning symptoms. All work operations should be monitored in such a way that emergency
personnel can be immediately contacted in the event of a release. Always store and handle compressed gas cylinders in
accordance with Compressed Gas Association, Inc. (telephone 703-412-0900) pamphlet CGA P-1, Safe Handling of Compressed
Gases in Containers. Local regulations may require specific equipment for storage and use.
SECTION 8. EXPOSURE CONTROLS / PERSONAL PROTECTION
VENTILATION AND ENGINEERING CONTROLS: Forced ventilation systems for the general work area should be
provided. Spectra Gases, Inc. recommends that cylinders in use be secured within a ventilated enclosure such as a gas cabinet.
Employee exposure should be monitored and reduced to the lowest practical levels using ventilation or other appropriate
engineering controls. (Spectra Gases is not aware of any workplace situation with good gas delivery system design where
exposure to any amount of this material is necessary under normal operating conditions. Ventilation is important for mitigating
vapor concentrations released in leak situations.)

The following information is for this gas mixture.
APPEARANCE, ODOR AND STATE: This gas mixture is a colorless gas mixture that may have a pungent odor characteristic
of Chlorine.
WARNING PROPERTIES FOR THIS MATERIAL: The odor of the Chlorine component of this gas mixture is not a good
warning property of a release, as it rapidly causes olfactory fatigue. Monitoring systems must be used for detection of this gas.
Small leaks may be detected by painting a soap solution on the suspected site of the leak. The leak will be indicated by bubble
formation.
SECTION 10. STABILITY AND REACTIVITY
CHEMICAL STABILITY: This gas mixture is stable under conditions of normal temperature and pressure.
CONDITIONS TO AVOID: Cylinders should not be exposed to temperatures in excess of 125癋 (52癈); avoid exposure to
incompatible materials.
MATERIALS WITH WHICH MATERIAL IS INCOMPATIBLE: Although the component of greatest percentage (Nitrogen)
is inert, the Chlorine present in this mixture will react with nearly all organic and inorganic materials including water. Chlorine is not
compatible with most metals (except titanium). Liquid or solid hydrocarbons (e.g. natural or synthetic rubbers, naphtha, turpentine,
gasoline, fuel gas, lubricating oil and waxes) can react violently and burn or explode. Hydrocarbon gases such as methane,
acetylene, ethylene or ethane can react explosively with chlorine if initiated by sunlight or a catalyst. Nitrogen compounds such as
ammonia can react with chlorine to form highly explosive nitrogen trichloride. Contact with chlorine gas and phosphorous, boron,
active carbon and silicon can cause ignition at room temperature. Certain concentrations of chlorine/hydrogen mixtures can
explode by spark or other source of ignition. Chlorine is also incompatible with alcohols, flammable liquids, flammable solids,
flammable gases. Chlorine can react with ammonia-based compounds to form toxic chloramine gas. The dilute concentration of
chlorine in this mix will lessen the incompatibility hazards.
REACTIVITY:
A) HAZARDOUS DECOMPOSITION PRODUCTS: Chlorine does not decompose, but reacts with water to form
hydrogen chloride. Chlorine also reacts with carbon monoxide to form phosgene. Nitrogen is inert and does not
decompose.
B) HAZARDOUS POLYMERIZATION: Will not occur.

MOBILITY: The components of this gas mixture should volatize rapidly and so should not present a significant hazard of mobility.
PERSISTENCE AND BIODEGRADABILITY: Persistence: The stability of free chlorine in natural water is very low
because it is a strong oxidizing agent and rapidly oxidizes inorganic compounds. It also oxidizes organic compounds, but more
slowly than inorganic compounds. Chlorination studies conducted on natural and artificial seawater, have shown two phases of
Chlorine losses in seawater: a rapid initial loss followed by a continuous loss at a sharply reduced rate. The initial loss reaches
a saturation level that varies widely between natural seawater samples and appears to be related to a true organic demand.
Losses continue over 10-day periods and are pronounced in seawater containing bromine. Other studies have indicated that
the loss of chlorine is associated with the bromide chemical system in seawater. The fate of the lost chlorine was not
determined. Biodegradation: This gas mixture will not biodegrade.
POTENTIAL TO BIOACCUMULATE: The Chlorine component is highly toxic to all forms of aquatic life; there is no
potential for bioaccumulation or bioconcentration.
OZONE-DEPLETION POTENTIAL: The components of this gas mixture are not Class I or Class II ozone depleting
chemicals (40 CFR Part 82).
