Potential health hazards
SKIN
Irritation would result from a defatting action on
tissue. Liquid contact could cause frostbite.
EYES
Liquid contact can cause severe irritation and
frostbite. Mist may cause irritation.
INHALATION
The refrigerant is low in acute toxicity in animals.
When oxygen levels in air are reduced to 12–
14% by displacement, symptoms of asphyxiation,
loss of coordination, increased pulse rate and
deeper respiration will occur. At high levels, cardiac
arrhythmia may occur.
INGESTION
Ingestion is unlikely because of the low boiling point
of the material. Should it occur, discomfort in the
gastrointestinal tract from rapid evaporation of the
material and consequent evolution of gas would
result. Some effects of inhalation and skin exposure
would be expected.
DELAYED EFFECTS
None known
Flammable properties
Material itself is not flammable. Its autoignition
temperature is 750 °C, 1,382 °F.
UNUSUAL FIRE AND EXPLOSION HAZARDS
The refrigerant is not flammable at ambient
temperatures and atmospheric pressure. However,
this material will become combustible when mixed
with air under pressure and exposed to strong
ignition sources. Contact with certain reactive
metals may result in formation of explosive or
exothermic reactions under specific conditions (for
example very high temperatures and/or appropriate
pressures).

First aid measures
Promptly flush skin with water until all chemical is
removed. If there is evidence of frostbite, bathe with
lukewarm water. Do not use hot water, and do not
rub. If water is not available, cover with a clean,
soft cloth or similar covering. Get medical attention
if symptoms persist. Treatment of overexposure
should be directed at the control of symptoms and
the clinical conditions.
Immediately flush eyes with large amounts of
water for at least 15 minutes. In case of frostbite,
water should be lukewarm, not hot. Lift eyelids
occasionally to facilitate irrigation. Get medical
attention if symptoms persist.
Immediately remove to fresh air. If breathing has
stopped, give artificial respiration. Use oxygen as
required, provided a qualified operator is available.
Get medical attention immediately. DO NOT give
epinephrine (adrenaline).
Ingestion is unlikely because of the physical
properties and is not expected to be hazardous. DO
NOT induce vomiting unless instructed to do so by a
physician.
Not applicable
Fire fighting measures
SPECIAL FIRE FIGHTING PRECAUTIONS AND
INSTRUCTIONS: Firefighters should wear self-
contained, NIOSH-approved breathing apparatus
for protection against possible toxic decomposition
products. Proper eye and skin protection should
be provided. Use water spray to keep fire-exposed
containers cool.
