3. HAZARD IDENTIFICATION
Potential Health Effects
Inhalation of high concentrations of vapor is harmful and may cause
heart irregularities, unconsciousness or death. Intentional misuse
or deliberate inhalation may cause death without warning. Vapor
reduces oxygen available for breathing and is heavier than air.
Liquid contact can cause frostbite.
HUMAN HEALTH EFFECTS:
Overexposure to the vapors by inhalation may include temporary
nervous system depression with anesthetic effects such as
dizziness, headache, confusion, incoordination, and loss of
consciousness. Higher exposures to the vapors 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.
one 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.
4. FIRST AID MEASURES
In case of contact, flush with lukewarm water. Do not use hot
water. If frostbite has occurred, call a physician.
In case of liquid contact, immediately flush eyes with plenty of
water for 15 minutes. Call a physician.
Immediately remove to fresh air. Keep person calm. Call a
physician. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen.
Not a probable route. However, in case of accidental ingestion,
call a physician.
ADVICE TO PHYSICIAN
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.
5. FIRE-FIGHTING MEASURES
FLASH POINT: No flash point
Fire and Explosion Hazards:
Cylinders may rupture under fire conditions. Decomposition may
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-407C is not flammable in air at temperatures up to 100 deg C (212
deg F) at atmospheric pressure. However, mixtures of R-407C with
high concentrations of air at elevated pressure and/or temperature
can become combustible in the presence of an ignition source.
R-407C can also become combustible in an oxygen enriched
environment (oxygen concentrations greater than that in air).
Whether a mixture containing R-407C and air, or R-407C 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-407C should
not be allowed to exist with air above atmospheric pressure or at
high temperatures; or in an oxygen enriched environment. For
example: R-407C should NOT be mixed with air under pressure for
leak testing or other purposes.
