: Cylinders are equipped with pressure and temperature relief devices, but may
still rupture under fire conditions. Decomposition may occur. Contact of
welding or soldering torch flame with high concentrations of refrigerant can
result in visible changes in the size and colour 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 to
disperse refrigerant vapors from the work area before using any open flames.
This substance is not flammable in air at temperatures up to 100 deg. C (212
deg. F) at atmospheric pressure. However, mixtures of this substance with
high concentrations of air at elevated pressure and/or temperature can
become combustible in the presence of an ignition source. This substance
can also become combustible in an oxygen enriched environment (oxygen
concentrations greater than that in air). Whether a mixture containing this
substance and air, or this substance 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,
this substance should not be allowed to exist with air above atmospheric
pressure or at high temperatures; or in an oxygen enriched environment. For
example this substance 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.
: In the event of fire, wear self-contained breathing apparatus. Use personal
protective equipment. Wear neoprene gloves during cleaning up work after a
fire.
: Cool containers/tanks with water spray. Self-contained breathing apparatus
(SCBA) is required if containers rupture and contents are released under fire
conditions.
Water runoff should be contained and neutralized prior to release.
: Evacuate personnel to safe areas. Ventilate area, especially low or enclosed
places where heavy vapours might collect.
