3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: 1,2-Dichlorotetrafluoroethane is a colorless non-flammable, liquefied gas with a
slightly ethereal odor. 1,2-Dichlorotetrafluoroethane can cause central nervous system depression after inhalation
exposures. Symptoms of such overexposure can include drowsiness, fatigue, and weakness. At high concentrations,
the gas can act as an asphyxiant, by displacing oxygen. Therefore, exposure to high concentrations of this gas can be
fatal. Frostbite can be caused by contact with rapidly expanding gases or the liquefied gas. This gas is not flammable
and not reactive in normal emergency response situations. However, if involved in a fire, 1,2-Dichlorotetrafluoroethane
can decompose to produce toxic gases (e.g., hydrogen fluoride, phosgene).
SYMPTOMS OF OVEREXPOSURE BY ROUTE OF EXPOSURE:
HAZARDOUS MATERIAL INFORMATION
The most significant route of overexposure for 1,2-

such contact can quickly subside.
HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. Overexposure to 1,2-
Dichlorotetrafluoroethane may cause the following health effects:
ACUTE: The most significant hazard associated with 1,2-Dichlorotetrafluoroethane is inhalation of high concentrations of
this product. Such overexposure can cause central nervous system depression and oxygen deficiency. Symptoms of
exposures include respiratory difficulty, ringing in ears, headaches, dizziness, indigestion, nausea. At high concentrations,
unconsciousness or death may occur. Contact with liquid or rapidly expanding gases (which are released under high
pressure) may cause frostbite.
CHRONIC: 1,2-Dichlorotetrafluoroethane may cause cardiac sensitization to epinephrine, based on animal tests. See
Section 11 (Toxicology Information) for additional data.

PART II What should I do if a hazardous situation occurs?
4. FIRST-AID MEASURES
RESCUERS SHOULD NOT ATTEMPT TO RETRIEVE VICTIMS OF EXPOSURE TO THIS PRODUCT WITHOUT
ADEQUATE PERSONAL PROTECTIVE EQUIPMENT. At a minimum, Self-Contained Breathing Apparatus and
Personal Protective equipment should be worn.
Remove victim(s) to fresh air, as quickly as possible. Trained personnel should administer supplemental oxygen and/or
cardio-pulmonary resuscitation, if necessary. Only trained personnel should administer supplemental oxygen.
In case of frostbite, place the frostbitten part in warm water. DO NOT USE HOT 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 in the armpit. Encourage victim to gently exercise the affected part while being warmed. Seek immediate
medical attention.
Victim(s) must be taken for medical attention. Rescuers should be taken for medical attention, if necessary. Take copy of

fluoride, hydrogen chloride, and carbonyl fluoride). 1,2-Dichlorotetra-
fluoroethane does not burn; however, containers, when involved in fire, may rupture or burst.
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. In the event of fire, cool containers of 1,2-Dichlorotetrafluoroethane with water to prevent failure.
Use a water spray or fog to reduce or direct vapors. If unruptured cylinders are exposed to heat, the cylinder may rupture
or burst and release the contents. It may be prudent to remove potentially heat-exposed cylinders from the area
surrounding a fire, if it is safe for firefighters to do so. Withdraw immediately in case of rising sounds from venting safety
device or any discoloration of tanks due to the fire.
6. ACCIDENTAL RELEASE MEASURES
SPILL AND LEAK RESPONSE: Uncontrolled releases should be responded to by trained personnel using pre-planned
procedures. Proper protective equipment should be used. In case of an accidental release, evacuate all personnel upwind
and away from affected area and protect people.
Minimum Personal Protective Equipment should be Level B: mechanically-resistant gloves and Self-Contained
Breathing Apparatus. Allow the gas to dissipate. Monitor the surrounding area for oxygen. Colorimetric tubes can be
used to detect the presence of 1,2-Dichlorotetrafluoroethane. Colorimetric tube readings should indicate that 1,2-
Dichlorotetrafluoroethane is not present in the atmosphere above levels listed in Section 2 (Composition and Information on
Ingredients) before non-emergency personnel are permitted to re-enter the area. The atmosphere must have at least 19.5
percent oxygen before personnel can be allowed in the area without Self-Contained Breathing Apparatus.
Attempt to close the main source valve prior to entering the area. If this does not stop the release (or if it is not possible to
reach the valve), allow the gas to release in-place or remove it to a safe area and allow the gas to be released there.

PART III How can I prevent hazardous situations from occurring?
7. HANDLING and STORAGE
WORK PRACTICES AND HYGIENE PRACTICES: As with all chemicals, avoid getting 1,2-Dichlorotetrafluoroethane IN
YOU. Do not eat or drink while handling chemicals. Be aware of any signs of dizziness, fatigue, or other symptoms of
exposure (see Section 3,, Hazard Identification); exposures to fatal concentrations of 1,2-Dichlorotetrafluoroethane could
occur without any significant warning symptoms.
STORAGE AND HANDLING PRACTICES: Cylinders should be stored in dry, well-ventilated areas away from sources of
heat. Compressed gases can present significant safety hazards. Store containers away from heavily trafficked areas and
emergency exits. Post 鈥淣o Smoking or Open Flames鈥? signs in storage or use areas. Do not use 1,2-
Dichlorotetrafluoroethane with or near incompatible chemicals, such as the following: sodium, potassium, calcium, zinc,
and magnesium, powdered aluminum. Acceptable materials for construction for equipment used in the handling of 1,2-
Dichlorotetrafluoroethane include most commonly used metals (steel, cast iron, brass, copper, tin, lead).
SPECIAL PRECAUTIONS FOR HANDLING GAS CYLINDERS: Protect cylinders against physical damage. Store in cool,
dry, well-ventilated area, away from sources of heat, ignition and direct sunlight. Do not allow area where cylinders are
stored to exceed 52掳C (125掳F). Use a check valve or trap in the discharge line to prevent hazardous backflow. Post 鈥淣o
Smoking or Open Flame鈥? signs in storage and use areas. 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. Never tamper with pressure relief devices in
valves and cylinders. 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 in-place (if provided), 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. Use check valve or trap in discharge line to
prevent hazardous backflow into the cylinder. Do not use oils or grease on gas-handling fittings or equipment.
After Use: Close main cylinder valve. Replace valve protection cap (if provided), Mark empty cylinders 鈥淓MPTY鈥?.
NOTE: Use only DOT or ASME code containers. Close valve after each use and when empty. Cylinders must not be
recharged except by or with the consent of owner. For additional information refer to the Compressed Gas Association
Pamphlet P-1, 鈥淪afe Handling of Compressed Gases in Containers鈥?. Additionally, refer to CGA Bulletin SB-2 鈥淥xygen
Deficient Atmospheres鈥?.
PROTECTIVE PRACTICES DURING MAINTENANCE OF CONTAMINATED EQUIPMENT: Follow practices indicated in
Section 6 (Accidental Release Measures). Make certain application equipment is locked and tagged-out safely. Purge gas
handling equipment with inert gas (e.g., nitrogen) before attempting repairs.
8. EXPOSURE CONTROLS - PERSONAL PROTECTION
VENTILATION AND ENGINEERING CONTROLS: Use with adequate ventilation. Local exhaust ventilation is preferred,
because it prevents 1,2-Dichlorotetrafluoroethane dispersion into the work place by eliminating it at its source. If necessary,
the work area should be monitored for the level of oxygen.
RESPIRATORY PROTECTION: Maintain 1,2-Dichlorotetrafluoroethane levels below those listed in Section 2 (Composition
and Information on Ingredients) and oxygen levels above 19.5% in the workplace. Use supplied air respiratory protection if
oxygen levels are below 19.5% or during emergency response to a release of 1,2-Dichlorotetrafluoroethane. If respiratory
protection is required, follow the requirements of the Federal OSHA Respiratory Protection Standard (29 CFR 1910.134), or
equivalent State standards. The following are NIOSH recommendations for 1,2-Dichlorotetrafluoroethane concentrations in
air:
CONCENTRATION RESPIRATORY EQUIPMENT
UP TO 10,000 ppm: Supplied Air Respirator (SAR).
UP TO 15,000 ppm: SAR operated in a continuous flow mode, full-facepiece Self-Contained Breathing Apparatus
(SCBA) or full-facepiece SAR.
Emergency or Planned Entry into Unknown Concentration or IDLH Conditions: Positive pressure, full-facepiece SCBA or
positive pressure, full-facepiece SAR with an auxiliary positive pressure SCBA.
Escape: Gas mask with canister to protect against organic vapors or escape-type SCBA.
NOTE: The IDLH concentration for 1,2-Dichlorotetrafluoroethane is 15,000 ppm.
EYE PROTECTION: Splash goggles or safety glasses, for protection from rapidly expanding. Face-shields should be
worn if contact with the liquefied gas is anticipated.

11. TOXICOLOGICAL INFORMATION
TOXICITY DATA: The following information is available for 1,2-Dichlorotetrafluoroethane.
LC50 (inhalation, rat) = 72 pph/30 minutes LC50 (inhalation, mouse) = 70 pph/30 minutes LC50 (inhalation, rabbit) = 750 pph/30 minutes
SHORT-TERM INHALATION: Irregular breathing, but no other toxic effects, were observed in guinea pigs exposed to 0.8-4.7% for 2 hours. Mice
exposed to 1% showed no clinical effects, but evidence of bleeding was found in the lungs. Decreased growth rate and some lung and blood
effects were observed in rats exposed 10-20% over the course of 2 weeks. Similar exposures to 10% showed no effects. Four of four dogs died
after exposure to 20% 8 hours a day for 3-4 days. Rats, guinea pigs, cats, and dogs showed no effects after twenty, 3.5 hour exposures to 10%
over 4 weeks.
SKIN IRRITATION: No significant irritation was observed on shaved rabbit skin sprayed with this product in sesame seed oil for 12 days. Repeated
spraying of this product on skin, tongue, soft palate, and ear canal of rats caused slight swelling and reddening; these effects may have been due to
evaporative cooling.
EYE IRRITATION: Irritation was observed in rabbits sprayed with 1,2-Dichlorotetrafluoroethane, but no permanent damage occurred.
CARDIOVASCULAR SYSTEM: The cardiac sensitization potential of this product is considered moderate This product caused irregular heartbeat
in monkeys (at 10%), dogs (5%) and mice (20%). Rapid heartbeat and low blood pressure developed in monkeys (1-10%) and dogs (10-20%).
Cardiac sensitization can be induced with endogenous epinephrine at levels of 5-8%. Animals exposed to concentrations above 10% experienced
respiratory problems such as reduced compliance and bronchioconstriction.
LONG-TERM INHALATION: Rats, monkeys, dogs, rabbits, and guinea pigs were exposed to 810 ppm 1,2-Dichlorotetrafluoroethane 24 hours/day
for 90 days. There were no deaths and the only pathologic changes observed was in the liver of exposed guinea pigs. At exposure levels of 20%,
there was an occurrence of generalized tremors, slight blood changes, and signs of mild narcosis.
SUSPECTED CANCER AGENT: 1,2-Dichlorotetrafluoroethane is not found on the following lists: FEDERAL OSHA Z
LIST, IARC, NTP, CAL/OSHA and therefore is not considered to be, nor suspected to be a cancer-causing agent by these
agencies.
IRRITANCY OF PRODUCT: 1,2-Dichlorotetrafluoroethane is not irritating; however, contact with rapidly expanding gases
can cause frostbite to exposed tissue.

RECOMMENDATIONS TO PHYSICIANS: Administer oxygen, if necessary. Treat symptoms and eliminate exposure. 1,2-
Dichlorotetrafluoroethane may cause cardiac sensitization to epinephrine, based on animal tests.
BIOLOGICAL EXPOSURE INDICES (BEIs): Currently, Biological Exposure Indices (BEIs) are not applicable for 1,2-
Dichlorotetrafluoroethane.
12. ECOLOGICAL INFORMATION
ENVIRONMENTAL STABILITY: This gas will be dissipated rapidly in well-ventilated areas. 1,2-Dichlorotetrafluoroethane
is a chlorofluorocarbon (CFC) compound. Chlorofluorocarbon compounds have been implicated in the possible depletion
of the stratospheric ozone, via a series of complex chemical reactions which occur in the upper atmosphere. Atmospheric
ozone is essential in protecting plants and animals from potentially harmful ultraviolet-light exposures. All work practice
must be directed at eliminating environmental contaminations.
EFFECT OF MATERIAL ON PLANTS or ANIMALS: Any adverse effect on animals would be related to adverse effects on
the central nervous system and to exposure to oxygen deficient environments. The symptoms experienced by over-
exposed animals would be similar to those described for exposed humans. No adverse effect is anticipated to occur to
plant-life, except for frost produced in the presence of rapidly expanding gases.
EFFECT OF CHEMICAL ON AQUATIC LIFE: No evidence is currently available on 1,2-Dichlorotetrafluoroethane鈥檚 effects
on aquatic life.
