2187FR DuPont Material Safety Data Sheet Page 3 (FIRST AID MEASURES - Continued) In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Call a physician. INGESTION Ingestion is not considered a potential route of exposure. Notes to Physicians Because of possible disturbances of cardiac rhythm, catecholamine drugs, such as epinephrine, should only be used with special caution in situations of emergency life support.
PAGE 4
2187FR DuPont Material Safety Data Sheet Page 4 (FIRE FIGHTING MEASURES - Continued) Experimental data have also been reported which indicate combustibility of HFC-134a in the presence of certain concentrations of chlorine. Extinguishing Media Use media appropriate for surrounding material. Fire Fighting Instructions Cool tank/container with water spray. Self-contained breathing apparatus (SCBA) may be required if cylinders rupture or release under fire conditions.
PAGE 5
2187FR DuPont Material Safety Data Sheet Page 5 (HANDLING AND STORAGE - Continued) Valve protection caps and valve cutlet threaded plugs must remain in place unless container is secured with valve outlet piped to use point. Do NOT drag, slide or roll cylinders. Use a suitable hand truck for cylinder movement. Never attempt to lift cylinder by its cap. Use a pressure reducing regulator when connecting cylinder to lower pressure (>3000 psig) piping or systems. Do NOT heat cylinder.
