| First Aid Measures | Back to Contents | 【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 | Back to Contents | 【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 | Back to Contents | 【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. | 【EC Safety Phrase】

| Exposure Controls/Personal Protection | Back to Contents | 【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】
