First Aid Measures
Ingestion
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid.
Ingestion
Not a likely route of exposure
Ingestion
These substances may cause frostbite to the upper airway and gastrointestinal tract after ingestion. Administer oxygen and manage airway as clinically indicated. Emesis, activated charcoal, and gastric lavage are not recommended.
Inhalation
Vapors may cause dizziness or asphyxiation without warning. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite.
Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Inhalation
The toxicological properties of this substance have not been fully investigated.
Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
Skin
No information regarding skin irritation and other potential effects was found.
Skin
Dermal contact may result in defatting, irritation or contact dermatitis. Severe frostbite has been reported as an effect of freon exposure. Injection causes transient pain, erythema and edema.
Skin
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Skin
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. If frostbite has occurred, refer to dermal treatment in the main body of this document for rewarming.
Eyes
See Skin.
Eyes
No information regarding eye irritation and other potential effects was found.
Eyes
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Eyes
If symptoms develop, immediately move individual away from exposure and into fresh air. Flush eyes gently with water for at least 15 minutes while holding eyelids apart; seek immediate medical attention.
Handling and Storage
Storage
May be stored over water.
Storage
Store in a cool, dry place. Store in a tightly closed container.
Handling
Wash thoroughly after handling. Use only in a well ventilated area. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Hazards Identification
Ingestion
The toxicological properties of this substance have not been fully investigated.
Inhalation
Vapors may cause dizziness or asphyxiation without warning.
Skin
Dermal contact may result in defatting, irritation or contact dermatitis. Severe frostbite has been reported as an effect of freon exposure. Injection causes transient pain, erythema and edema.
Eyes
See Skin.
Ingestion
Nausea may develop. Ingestion of a small amount of trichlorofluoromethane resulted in necrosis and perforation of the stomach in one patient.
Hazards
Containers may explode when heated. Ruptured cylinders may rocket.

Exposure Controls/Personal Protection
Personal Protection
Wear appropriate chemical protective clothing.
Personal Protection
Wear appropriate protective gloves, clothing and goggles. Always wear thermal protective clothing when handling refrigerated/cryogenic liquids.
Personal Protection
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
Respirators
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Respirators
Wear positive pressure self-contained breathing apparatus.
Exposure Effects
Headache, dizziness, and disorientation are common. Cerebral edema may be found on autopsy. Dichlorodifluoromethane was not teratogenic in rats and rabbits. <br>The reproductive effects of 1,1,1,2-tetrafluoroethane were studied in rats. No adverse effects on reproductive performance was noted or on the development, maturation or reproductive performance of up to two successive generations.

Fire Fighting
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Do not use water on material itself. Use water spray to knock-down vapors.
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam.
Upper exp. limit
35.3
Fire Potential
May burn but does not ignite readily.
Accidental Release Measures
Small spills/leaks
Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors.
Small spills/leaks
Make no contact with the spilled material. Stop leak if you can do it without risk. Do not direct water at spill or source of leak. If possible, turn leaking containers so that gas escapes rather than liquid. Allow substance to evaporate. Ventilate the area.
Small spills/leaks
Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal.
Stability and Reactivity
Stability
No data.
Stability
Stable up to 1150 C.
Incompatibilities
Strong oxidizing agents, strong acids.
Incompatibilities
Attacks magnesium and its alloys.
Decomposition
Carbon monoxide, oxides of nitrogen, carbon dioxide.
