Hazards and Protection.
Keep away from heat and flame. Store in a cool, dry place. Do not store in direct sunlight.
Wash thoroughly after handling. Use with adequate ventilation. Avoid contact with skin and eyes. Do not get on skin or in eyes.
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.
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.
Absorb the liquid and scrub the area with detergent and water.
Stable under normal temperatures and pressures.
Alkali and alkaline earth metals, powdered aluminum, zinc, magnesium and beryllium.
Hydrofluoric acid, carbonyl fluoride.
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.
May burn but does not ignite readily.
Containers may explode when heated. Ruptured cylinders may rocket.
All fluorocarbons will undergo thermal decomposition when exposed to flame or red-hot metal.
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.
Aspiration hazard. May cause irritation of the digestive tract.
Vapor reduces oxygen available for breathing. May cause dyspnea (difficult breathing from shortness of breath).
May cause frostbite.
Not available. Contact with liquid may cause severe tissue damage because of frostbit e.
Do NOT induce vomiting. Get medical aid.
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Get medical aid if irritation develops or persists. Treat for frostbite.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
