FIRST AID MEASURES CONTINUED,
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.

HFC-134A is not flammable at ambient temperatures and atmospheric pressure. However, HFC-
134A has been shown in tests to be combustible at pressures as low as 5.5 psig at 177 C (351 F)
when mixed with air at concentrations of 60 volume % air. At lower temperatures, higher pressures
are required for combustibility. Experimental data have also been reported which indicate
combustibility of HFC 134A in the presence of certain concentrations of chlorine.
FIRE AND EXPLOSION HAZARDS:
Cylinders may rupture under fire conditions. Decomposition may occur. Contact of welding or
soldering torch flame with high concentrations of refrigerent can result in visible changes in the size
and color of the torch flame. This flame effect will only occur in concentrations of product well
above the recommended exposure limit, therefore stop all work and ventilate the area before
proceeding. Use forced ventilation to disperse refrigerant vapors from the work area before using any
open flames.
Extinguishing Media
As appropriate for combustibles in area. Extinguishant for other burning material in area is sufficient
to stop burning.
Fire Fighting Instructions
Cool tank/container with water spray. Self-contained breathing apparatus (SCBA) is required if
cylinders rupture or contents are released under fire conditions.
