Inhalation of high concentrations of vapour is harmful and may cause heart irregularities,
unconsciousness, or death. Intentional misuse or deliberate inhalation may cause death
without warning. Vapour reduces oxygen available for breathing and is heavier than air. Liquid
contact can cause frostbite.
At flame temperatures, this material can decompose to hydrogen fluoride which can be lethal
at much lower concentrations.
Overexposure to the vapours by inhalation may include temporary nervous system
depression with anaesthetic effects such as dizziness, headache, confusion, incoordination,
and loss of consciousness. Higher exposures to the vapours may cause temporary alteration
of the heart's electrical activity with irregular pulse, palpitations, or inadequate circulation.
Gross overexposure may be fatal. Skin contact with the liquid may cause frostbite.
Individuals with preexisting diseases of the central nervous or cardiovascular system may
have increased susceptibility to the toxicity of increased exposures.
None of the components present in this material at concentrations equal to or greater than
0.1% are listed by IARC, NTP, OSHA or ACGIH as a carcinogen.
If inhaled, immediately remove to fresh air. Keep person calm.
If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician.
Flush area with lukewarm water. Do not use hot water. If frostbite has occurred, call a
physician.
In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Call a
physician.
Do not induce vomiting. Give plenty of water in sips
THIS MATERIAL MAY MAKE THE HEART MORE SUSCEPTIBLE TO ARRHYTHMIAS.
Catecholamines such as adrenaline, and other compounds having similar effects, should be
reserved for emergencies and then used only with special caution.
Flash Point : No flash point
Flammable Limits in Air, % by Volume:
LEL : None per ASTM E681
UEL : None per ASTM E681
Autoignition: Not determined
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 colour 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 vapours 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.
