Containers shall be marked with warning labels
12、as follows: DICHLOROFLUOROETHANE HCFC- 14 1 b Eye contact with vapor causes irritation. Contact with liquid can cause chemical bums. Prolongedkepeated skin contact may cause dryness/irritation. Exposure can also result in freezing of skin tissue (frost bite). Over-exposure to vapor may cause respira
13、tory system irritation, headache, dizziness and central nervous system (CNS) depression. Exposure to higher levels may also result in increasing sensitivity of the heart to adrenaline. Cardiac arrhythmia could result. Exposure to very high levels could result in death due to dilutioddisplacement of
14、available oxygen, resulting in death by asphyxiation. Low areas are especially susceptible to oxygen displacement. Taste/odor do not provide adequate warning of high vapor levels. Do not use in the general vicinity of welding, open flames or hot surfaces. This could result in the decomposition of th
15、is material to irritating and toxic gases and carbonyl halides. In case of spills/significant release to work space, warn others and leave immediately. Use smallest quantity possible to properly perform the operation. Use only with adequate ventilation. Refer to Material Safety Data Sheet for additi
16、onal information and required precautions for use. Consult medical department authority for guidance in control and proper use of this material, and specific requirements and methods for monitoring vapor levels in the workspace. Have an emergency escape breathing device (EEBD) immediately available
17、for any operation where overexposure to product could occur unless immediate escape to a vapor-free area is possible. Be sure you are trained in the proper care, inspection, and use of this device. Ensure storage areas that contain this product are properly ventilated prior to entry. 3 Provided by I

If breathing has stopped, give artificial respiration. In cases of excessive exposure, pay particular attention
19、 to the potential for cardiac arrhythmia. Oxygen may be used in treating such cases if administered by medical department personnel. Use of vaso-pressor drugs, for example epinephrine (adrenaline), is inadvisable because these drugs may induce cardiac arrhythmia. If high temperature decomposition pr
20、oducts may have been inhaled, observe the patient for immediate or delayed signs of pulmonary edema. In any of these cases, obtain prompt medical attention. NOTE TO PHYSICIANS: Overexposure to dichlorofluoroethane has caused cardiac sensitization to epinephrine. Cardiac arrhythmia, including ventric
21、ular fibrillation could occur if epinephrine or one of its congeners is administered to patients exposed to high concentrations of dichlorofluoroethane. Medical use of epinephrine or any of its congeners is contra-indicated except for patients with no arterial profusion. Skin contact: If pain or fre
22、ezing of tissue occurs, seek prompt medical attention. If no freezing of the skin is apparent, wash areas with wann water. If material soaks through clothing, remove clothing and wash skin with soap or mild detergent and water. If irritation persists after washing, obtain medical attention. Do not r
23、e-use contaminated clothing until it is thoroughly cleaned to remove the material. Eye contact: Immediately wash with large amounts of potable water for a minimum of 15 minutes. Avoid use of any other agents such as oil or saline solutions in the eye. Use of any other agent or dressing should only b
24、e administered by the cognizant medical department representative. Contact lens should not be worn when using this chemical. Ingestion: Do not induce vomiting. Seek medical attention. 2.7 Delivery options. The 1,1-dichloro-1-fluoroethane may be delivered in 5 or 55 gallon drums, or in bulk container
25、s (tank truck, tank railroad car). that have been precleaned.
