MATERIAL SAFETY DATA
Refrigerant Safety Data R410A:
COMPOSITION/INFORMATION ON INGREDIENTS
Components Material PENTAFLUOROETHANE (HFC-125) DIFLUOROMETHANE (HFC-32)
CAS Number 354-33-6 75-10-5
% 50 50
HAZARDS IDENTIFICATION
Potential Health Effects 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.
Human Health Effects 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.
Carcinogenicity Information 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.
FIRST AID MEASURES
Inhalation 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.
Skin Contact Flush area with lukewarm water. Do not use hot water. If frostbite has occurred, call a
physician.
Eye Contact In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Call a
physician.
Ingestion Do not induce vomiting. Give plenty of water in sips
Notes to Physicians 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.
FIRE FIGHTING MEASURES
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 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.

Refrigerant Safety Data R410A:
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 1
if cylinders rupture and contents are released under fire conditions. Water runoff should be
contained and neutralized prior to release.
ACCIDENTAL RELEASE MEASURES
Safeguards (Personnel) NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL)
sections before proceeding with clean-up. Use appropriate PERSONAL PROTECTIVE
EQUIPMENT during clean-up.
Accidental Release Measures Ventilate area, especially low or enclosed places where heavy vapours might collect.
Extinguish open flames. Use self-contained breathing apparatus (SCBA) for large spills or
releases. Eliminate electrical sources.
HANDLING AND STORAGE
Handling (Personnel) Avoid breathing vapour. Avoid liquid contact with eyes and skin. Use with sufficient ventilation
to keep employee exposure below recommended limits. See Fire and Explosion Data section.
Storage Clean, dry area. Do not heat above 52 deg C (125 deg F).
EXPOSURE CONTROLS/PERSONAL PROTECTION
Engineering Controls Avoid breathing vapours. Avoid contact with skin or eyes. Use with sufficient ventilation to
keep employee exposure below the recommended exposure limit. Local exhaust should be
used if large amounts are released. Mechanical ventilation should be used in low or enclosed
places.
Personal Protective Impervious gloves should be used to avoid prolonged or repeated exposure. Chemical splash
Equipment goggles should be available for use as needed to prevent eye contact. Under normal
manufacturing conditions, no respiratory protection is required when using this product
provided exposure is maintained at or below occupational limits. Self-contained breathing
apparatus (SCBA) is required if a large release occurs.

Single exposure to high doses caused: Lethargy. Laboured breathing. Weak cardiac
sensitization, a potentially fatal disturbance of heart rhythm caused by a heightened
sensitivity to the action of epinephrine. Lowest-Observed-Adverse-Effect-Level for cardiac
sensitization: 100,000 ppm.
Repeated exposure caused: No significant toxicological effects. No-Observed-Adverse-Effect-
Level(NOAEL): 50,000 ppm
ADDITIONAL TOXICOLOGICAL EFFECTS:
No animal data are available to define the following effects of this material: carcinogenicity,
reproductive toxicity. In animal testing this material has not caused developmental toxicity.
Tests have shown that this material does not cause genetic damage in bacterial or
mammalian cell cultures, or in animals. This material has not been tested for its ability to
cause permanent genetic damage in reproductive cells of mammals (not tested for heritable
genetic damage).
HFC-32
Inhalation 4 hour-ALC: > 520,000 ppm in rats
Single exposure caused: Lethargy. Spasms. Loss of mobility in the hind limbs. Other effects
include weak cardiac sensitization, a potentially fatal disturbance of heart rhythm caused by a
heightened sensitivity to the action of epinephrine. 250,000 ppm.
Repeated exposure caused pathological changes of the lungs, liver, spleen, kidneys. In more
recent studies repeated exposure caused: No significant toxicological effects.
No-Observed-Effect-Level (NOEL): 49,100 ppm.
No animal data are available to define the following effects of this material: carcinogenicity,
reproductive toxicity. Animal data show slight fetotoxicity but only at exposure levels
producing other toxic effects in the adult animal. Tests have shown that this material does not
cause genetic damage in bacterial or mammalian cell cultures, or in animals. This material
has not been tested for its ability to cause permanent genetic damage in reproductive cells of
mammals (not tested for heritable genetic damage).
