# Flammable Properties
Flash Point : No flash point
Flammable Limits in Air, % by Volume:
LEL : None per ASTM E681
UEL : None per ASTM E681
Autoignition: Not determined
Fire and Explosion Hazards:
Cylinders 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 limit, therefore stop all work and
ventilate to disperse refrigerant vapors from the work area
before using any open flames.
R-410A is not flammable in air at temperatures up to 100
deg C (212 deg F) at atmospheric pressure. However,
mixtures of R-410A with high concentrations of air at
elevated pressure and/or temperature can become combustible
in the presence of an ignition source. R-410A can also
become combustible in an oxygen enriched environment (oxygen
concentrations greater than that in air). Whether a mixture
containing R-410A and air, or R-410A in an oxygen enriched
atmosphere becomes combustible depends on the
inter-relationship of 1) the temperature 2) the pressure,
and 3) the proportion of oxygen in the mixture. In general,
R-410A should not be allowed to exist with air above
atmospheric pressure or at high temperatures; or in an
oxygen enriched environment. For example: R-410A 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
Cool cylinder with water spray or fog. Self-contained
breathing apparatus (SCBA) is required if cylinders rupture
and contents are released under fire conditions. Water
runoff should be contained and neutralized prior to release.
