Component CAS # 811-97-2 Concentration 100%




SECTION IV-First Aid Measures

Skin: In case of contact, immediately flush skin with plenty of water for at least 15 minutes. Take off all contaminated clothing immediately. Take off all contaminated clothing immediately. Consult a physician. Wash contaminated clothing before re-use. Treat for frostbite if necessary by gently warming affected area.


Eye contact: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes.

Consult a physician if necessary.


Inhalation: Remove from exposure, lie down. Move to fresh air. Keep patient warm and rest. Artificial respiration and/or oxygen may be necessary. Consult a physician.


Ingestion: Is not considered a potential route of exposure.


General advice: Never give anything by mouth to an unconscious person. When symptoms persist or in all cases of doubt seek medical advice.


Notes to Physician: Because of possible disturbances of cardiac rhythm, catecholamine drugs, such as epinephrine, that may be used in situations of emergency life support should be used with special caution.


SECTION V-Firefighting Measures

Flammable Properties

Flash Point: does not flash

Ignition: > 743 C (< 1,369 C (< 1,369 F) at 1,013 hPa

Lower explosion limit: Method: None per ASTM E681

Upper explosion limit: Method: None per ASTM E681

Fire explosion Hazard: Hazardous thermal decomposition products:

Carbon oxides

Hydrogen fluoride

Carbonyl fluoride

Cylinders are equipped with pressure and temperature relief devices, but may still rupture under fire conditions. Decomposition may occur. Contact of welding or soldering torch flame with high concentrations of refrigerant can result in visible changes in the size and color of the torch flame. This flame effect will only occur in concentrations of product well above the recommended exposure limit.

Therefore stop all work and ventilate to disperse refrigerant vapors from the work area before using any

open flames. This substance is not flammable in air at temperature up to 100 deg. C (212 deg. F) at atmospheric pressure. However, mixtures of this substance with high concentrations of air at elevated pressure and/or temperature can become combustible in the presence of an ignition source. This substance can also become combustible in an oxygen enriched environment (oxygen concentrations greater than that in air). Whether a mixture containing this substance and air, or this substance in oxygen enriched atmosphere become combustible depends on the inter-relationship of 1) the temperature 2) the

pressure, and 3) the proportion of oxygen in the mixture. In general this substance should no be allowed to exist with air above atmospheric pressure or at high temperatures; or in an oxygen enriched environment. For example this substance should NOT be mixed with air under pressure for leak testing or

other purposes.

Experimental data have also been reported which indicate combustibility of this substance in the presence of certain concentrations of chlorine.



extinguishing media Use extinguishing measures that are appropriate to local circumstances and the surrounding environment.

Firefighting Instructions: In the event of fire, wear self-contained breathing apparatus.

Cool containers / tanks with water spray. Water runoff should be contained and neutralized prior to



SECTION VI-Accidental Release Measures

NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL) section before proceeding with clean up. Use appropriate

PERSONAL EQUIPMENT during clean-up.


Safeguards (Personnel): Evacuate personnel to safe areas. Ventilate area, especially low or enclosed places where heavy vapours

might collect.

Spill Cleanup: Evaporates.



Release Measures: Should not be released into the environment.

Self-contained breathing apparatus (SCBA) is required if a large release occurs. Avoid open flames and

high temperatures.


SECTON VII-Handling and Storage

Handling (Personnel): Use sufficient ventilation to keep employee exposure below recommended limits. For personal protection

See section 8.

Handle in accordance with good industrial hygiene and safety practice.



(Physical Aspects): The product should not be mixed with air for leak testing or used with air for any other purpose above

atmospheric pressure. Contact with chlorine or other strong oxidizing agents should also be avoided.


Storage: Valve protection caps and valve outlet threaded plugs must remain in place unless container is secured

with valve outlet piped to use point. Do not drag, slide or roll cylinders. Use a suitable hand truck for

Use a pressure reducing regulator when connecting cylinder to lower pressure

(>3000 psig) piping or systems. Never attempt to lift cylinder by its cap. Use a check valve or trap

in thedischarge line to prevent hazardous back flow into the cylinder.

Cylinders should be stored upright and


Firmly secured to prevent falling or being knocked over.

Separate full containers from empty containers. Keep at temperature not exceeding 52C. Don not store

Near combustible materials. Avoid area where salt or other corrosive are present.


Storage temperature: < 52 C (< 126 F)


SECTION VIII-Exposure Controls/Personal Protection

Engineering Controls: Normal ventilation for standard manufacturing procedures is generally adequate. Local exhaust should be used when large amounts are released. Mechanical ventilation should be used in low or enclosed places. Refrigerant concentration monitors may be necessary to determine vapor concentrations in work areas prior to use of torches or other open flames, or if employees are entering enclosed areas.


Personal protective equipment

Respiratory protection: For rescue and maintenance work in storage tanks use self-contained.

breathing apparatus. Vapors are heavier than air and can cause suffocation by reducing oxygen available for breathing.



Hand protection: Additional protection: Impervious gloves


Eye protection: Wear safety glasses with side shields. Additionally wear a face shield where the possibility exists for face contact due to splashing, spraying or airborne contact with this material.


Protective measures: Self-contained breathing apparatus (SCBA) is required if a large release occurs.
