HFC-134a is not flammable in air at temperatures up to 100 deg. C (212 deg.
F) at atmospheric pressure. However, mixtures of HFC-134a with high
concentrations of air at elevated pressure and/or temperature can become
combustible in the presence of an ignition source. HFC-134a can also
become combustible in an oxygen enriched environment (oxygen
concentrations greater than that in air). Whether a mixture containing HFC-
134a and air, or HFC-134a in an oxygen enriched atmosphere become
combustible depends on the inter-relationship of 1) the temperature 2) the
pressure, and 3) the proportion of oxygen in the mixture. In
general, HFC-134a should not be allowed to exist with air above atmospheric
pressure or at high temperatures; or in an oxygen enriched environment. For
example HFC-134a should NOT be mixed with air under pressure for leak
testing or other purposes.
Experimental data have also been reported which indicate combustibility of
this substance in the presence of certain concentrations of chlorine.
Suitable extinguishing media :
Use extinguishing measures that are appropriate to local circumstances and
the surrounding environment.
Firefighting Instructions :
In the event of fire, wear self-contained breathing apparatus.
Cool containers / tanks with water spray. Water runoff should be contained
and neutralized prior to release.
SECTION 6. ACCIDENTAL RELEASE MEASURES
NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL) sections before proceeding with clean-
up. Use appropriate PERSONAL PROTECTIVE EQUIPMENT during clean-up.
Safeguards (Personnel) :
Evacuate personnel to safe areas. Ventilate area, especially low or enclosed
places where heavy vapours might collect.
Spill Cleanup
:
Evaporates.
Accidental Release Measures :
Should not be released into the environment.
Self-contained breathing apparatus (SCBA) is required if a large release
occurs. Avoid open flames and high temperatures.
