Fire and Explosion Hazards:
Containers may 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 color of torch flames. This flame effect
will only occur in concentrations of product well above the
recommended exposure limits, therefore, stop all work and
ventilate to disperse refrigerant vapors from the work area
before using any open flames.
HFC-23 is not flammable in air at temperatures up to 100
deg. C (212 deg. F) at atmospheric pressure. However,
mixtures of HFC-23 with high concentrations of air at
elevated pressure and/or temperature can become combustible
in the presence of an ignition source. HFC-23 can also
become combustible in an oxygen enriched environment (oxygen
concentrations greater than that in air). Whether a mixture
containing HFC-23 and air, or HFC-23 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-23 should not be allowed to exist with air above
atmospheric pressure or at high temperatures; or in an
oxygen enriched environment. For example, HFC-23 should NOT
be mixed with air under pressure for leak testing or other
purposes.
Extinguishing Media
As appropriate for combustibles in area.
Fire Fighting Instructions
Use water spray or fog to cool containers. Self-contained
breathing apparatus (SCBA) is required if cylinders rupture
or release under fire conditions. Water runoff should be
contained and neutralized prior to release.
