First Aid Measures

Ingestion
Do NOT induce vomiting. Get medical aid.
Inhalation
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Skin
Get medical aid if irritation develops or persists. Treat for frostbite.
Eyes
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.

Handling and Storage

Storage
Keep away from heat and flame. Store in a cool, dry place. Do not store in direct sunlight.
Handling
Wash thoroughly after handling. Use with adequate ventilation. Avoid contact with skin and eyes. Do not get on skin or in eyes.

Hazards Identification

Inhalation
Vapor reduces oxygen available for breathing. May cause dyspnea (difficult breathing from shortness of breath).
Skin
May cause frostbite.
Eyes
Not available. Contact with liquid may cause severe tissue damage because of frostbit e.
Ingestion
Aspiration hazard. May cause irritation of the digestive tract.
Hazards
Containers may explode when heated. Ruptured cylinders may rocket.

Exposure Controls/Personal Protection

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 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.
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.
Poison Class
-

Fire Fighting Measures

Flash Point
-79
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Extinguishing media: For small fires, use water spray, dry chemical, carbon dioxide or chemical foam.
Fire Potential
May burn but does not ignite readily.

Accidental Release Measures

Small spills/leaks
Absorb the liquid and scrub the area with detergent and water.

Stability and Reactivity

Incompatibilities
Alkali and alkaline earth metals, powdered aluminum, zinc, magnesium and beryllium.
Stability
Stable under normal temperatures and pressures.
Decomposition
Hydrofluoric acid, carbonyl fluoride.
Combustion Products
All fluorocarbons will undergo thermal decomposition when exposed to flame or red-hot metal.
