Avoid breathing refrigerant or lubricant vapor or mist.
Exposure may irritate eyes, nose and throat.
If accidental system discharge occurs, ventilate work area before resuming service.
Additional health and safety information may be obtained from refrigerant and
lubricant manufacturers.
Special Considerations with R134a
R134a has been shown to be nonflammable at ambient temperature and atmospheric
pressure. However, tests under controlled conditions have indicated that, at pressures
above atmospheric and with air concentrations greater than 60% by volume, R134a
can form combustible mixtures.
While it is recognized that an ignition source is also required for combustion to occur,
the presence of combustible mixtures is a potentially dangerous situation and should
be avoided.
Under no circumstances should any equipment be pressure tested or leak tested with
Air/R134a mixtures. Do not use compressed air (shop air) for leak detection in
R134a systems.
