2. HAZARDS IDENTIFICATION
Physical Hazard: Gases under pressure Liquefied Gas
Label elements:
Single Word: Warning
Hazard Statements
Contains gas under pressure; may explode if heated.
May displace oxygen and cause rapid suffocation.
Precautionary Statements
Protect from sunlight.
Store in a well-ventilated place.
Pressurized container. Do not pierce or burn, even after use.
Other Hazards
Vapors are heavier than air and can cause suffocation by reducing oxygen available for breathing. Misuse or intentional inhalation
abuse may lead to death without warning symptoms, due to cardiac effects. Rapid evaporation of the product may cause frostbite.

3. INGREDIENTS
Material (s) CAS No. Approximate %
1,1,1,2 Tetrafluoroethane 811-97-2 100
4. FIRST AID MEASURES
Inhalation: Remove patient to fresh air. Get medical attention.
Eye: Get medical attention immediately.
Skin: Thaw frosted parts with lukewarm water. Do not rub affected area. Get medical attention immediately.
Oral: Ingestion is not considered a potential route of exposure.
Most important symptoms/effects, acute and delayed: May cause cardiac arrhythmia.
Other symptoms potentially related to misuse or inhalation abuse: Cardiac sensitization, Anaesthetic effects, Light-headedness,
Dizziness, Confusion, Lack of coordination, Drowsiness, Unconsciousness.
Contact with liquid or refrigerated gas can cause cold burns or frostbite.
Notes to Physician: Treat symptomatically and supportively.
5. FIRE FIGHTING MEASURES
Suitable Extinguishing Media: Not applicable. Will not burn.
Unsuitable extinguishing media: Not applicable. Will not burn.
Special hazards: Aerosol cans may rupture under fire conditions Exposure to combustion products may be hazardous to health.
Hazardous combustion products: Hydrogen fluoride, Carbonyl fluoride, Carbon oxides.
Specific extinguishing methods: Use extinguishing measures that are appropriate to local circumstances and the surrounding
environment. Evacuate personnel to safe areas. Cool containers with water spray. Fight fire remotely due to risk of explosion.
Protective Equipment for Fire-Fighters: Self-contained breathing apparatus if necessary. Use personal protective equipment.
6. ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment and emergency procedures: Aerosols can explode when heated. Ventilate area. Warn
personnel of this hazard and unprotected personnel should not return until safe to do so. Follow safe handling advice and personal
protective equipment recommendations. Avoid skin contact with leaking liquid (danger of frostbite).
Environmental Precautions: Prevent further leakage or spillage, if safe to do so.
Spill Clean Up Methods: Ventilate area. Local and national regulations may apply to releases and disposal of this material.
MS-242N pg. 3 of 6
7. HANDLING AND STORAGE
Handling: Avoid inhalation of vapors. Use in a well-ventilated area to keep employee exposure below recommended limits. Use an
approved respirator if necessary. Avoid contact with naked flames and hot surfaces as toxic decomposition products can be formed. Do
not get in eyes or on skin.
Storage Conditions: Store in a clean, dry place, not near sources of heat, in direct sunlight or where temperatures exceed 122

8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Exposure Limits: TLV (ACGIH) PEL (OSHA) US WEEL
1,1,1,2-Tetrafluoroethane Not Established Not Established 1000 ppm (TWA)
Engineering Measures: Use adequate ventilation. Vapors are heavier than air and if working in confined or poorly ventilated areas,
proper respiratory protection must be used to prevent exceeding the exposure limit.
Respiratory Protection: General and local exhaust ventilation is recommended to maintain vapor exposures below recommended
limits. Where concentrations are above recommended limits or are unknown, appropriate respiratory protection should be worn. Follow
OSHA respirator regulations (29 CFR 1910.134) and use NIOSH/MSHA approved respirators. Protection provided by air purifying
respirators against exposure to any hazardous chemical is limited. Use a positive pressure air supplied respirator if there is any potential
for uncontrolled release, exposure levels are unknown, or any other circumstance where air purifying respirators may not provide
adequate protection.
Eye Protection: Avoid eye contact. Use chemical goggles or safety glasses with side shields.
Skin Protection: Avoid contact with skin. Use gloves impervious to this material. For special applications, we recommend clarifying
the resistance to chemicals of the afore mentioned protective gloves with the glove manufacturer. Wash hands before breaks and at the
end of workday. Breakthrough time is not determined for the product. Change gloves often.
Hygiene Measures: Good personal hygiene practices are always advisable. Do not eat, drink, or smoke when using.
