Emergency overview Colourless, volatile liquid with ethereal and faint sweetish odor.
Non-flammable material. Overexposure may cause dizziness and
loss of concentration. At higher levels, CNS depression and cardiac
arrhythmia may result from exposure. Vapors displace air and can
cause asphyxiation in confined spaces. At higher temperatures, (> 250
°C, 482 °F ), decomposition products may include Hydrofluoric Acid
(HF) and carbonyl halides.
4 (63) CHS01 1951EN

Potential health hazards First aid measures
SKIN: Irritation would result from a defatting action
on tissue. Liquid contact could cause frostbite.
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.
EYES: Liquid contact can cause severe irritation
and frostbite. Mist may irritate.
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.
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.
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: 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.
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.
DELAYED EFFECTS: None known Not applicable
Flammable properties Fire fighting measures
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).
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.
Risks Preventive measures
EXPOSURE CONTROLS, PERSONAL
PROTECTION, AND ACCIDENTAL RELEASE
MEASURES

IN CASE OF SPILL OR OTHER RELEASE: Always wear recommended personal protective
equipment. Evacuate unprotected personnel.
Protected personnel should remove ignition sources
and shut off leak, if without risk, and provide
ventilation. Unprotected personnel should not
return until air has been tested and determined
safe, including low-lying areas. Spills and releases
may have to be reported to federal and/or local
authorities. Regarding reporting requirements refer
to the Material Safety Data Sheet of the refrigerant
manufacturer.
ENGINEERING CONTROLS: Provide local ventilation at filling zones and areas
where leakage is probable. Mechanical (general)
ventilation may be adequate for other operating and
storage areas.
CHS01 1951EN 5 (63)

Risks Preventive measures
PERSONAL PROTECTIVE EQUIPMENT: SKIN PROTECTION: Skin contact with refrigerant
may cause frostbite. General work clothing and
gloves (leather) should provide adequate protection.
If prolonged contact with liquid or gas is anticipated,
insulated gloves constructed of PVA, neoprene or
butyl rubber should be used. Any contaminated
clothing should be promptly removed and washed
before reuse.
EYE PROTECTION: For normal conditions,
wear safety glasses. Where there is reasonable
probability of liquid contact, wear chemical safety
goggles.
Where contact with liquid is likely, such as in a spill
or leak, impervious boots and clothing should be
worn.
DISPOSAL CONSIDERATIONS: Not a hazardous waste
WARNING: DO NOT vent to the atmosphere.
To comply with provisions of the U.S. Clean Air
Act, any residual must be recovered. Contains
greenhouse gas which may contribute to global
warming.
The refrigerant should not be mixed with air above atmospheric pressure for leak
testing or any other purpose.
1.2 Transportation and storage
Transport and store the heat pump in a vertical position.
Be careful when lifting the heat pump. Use appropriate lifting tools.
Preparations for storage, transfer, and lifting
1. Check that the way is free from obstacles.
2. Use appropriate vehicle for transport.
3. At installation site check that you have proper means and resources for lifting and
placing the pump.
Storage
Before transporting to the final installation site and commissioning phase, the heat
pump must not be stored longer than needed. If the heat pump must be stored longer
than one month, the manufacturer must be informed. The heat pump must be stored in
a dry place where the temperature is at least + 5 °C.

1.4 Information regarding the refrigerant R1234ze(E)
If the ChillHeat product contains fluorinated greenhouse gas R1234ze(E) (F-gas
regulation N° 517/2014) (Global Warming Potential GWP: 1, classified in safety group
A2L), it should be equipped with a ventilated enclosure system or be installed in a
special machinery room. The machinery room must conform to the requirements set in
EN 378-3 (2016) clause 5. Please ask Oilon sales for the details.
R1234ze(E) is classified group 2 “non-dangerous” according to the criteria of Pressure
Equipment Directive (PED) both 97/23/CE and 2014/68/CE.
R1234ze(E) is classified in safety group A2L (EN-378 (2016), ASHRAE
Standard-2010). It is in the lower segment of the mildly flammable refrigerants. A
unique characteristic of this refrigerant is the absence of flammable mixture with air
below 30 °C of ambient temperature. That’s why it is nonflammable for handling and
storage.
When utilized in a system, R1234ze(E) could become flammable with air in case of a
leakage. If a flame occurs with R1234ze(E), the effect of this flame would be extremely
mild, as its very low heat of combustion combined with an ultra-low burning velocity
wouldn’t be enough to propagate a fire.
When selecting the installation location for product using R1234ze(E), local building
codes and safety standards shall be followed and approval shall be obtained from
the local building authorities. In absence of local codes and standards, please refer to
EN-378 (2016) or to ISO-5149 (2014) as a guideline.
For further details on physical properties, flammability & toxicity characteristics,
hazards identification, installation safety requirements, etc., refer to standards such as:
● ASHRAE 34, EN 378, ISO-817 and ISO-5149
● Safety Data Sheet (SDS) supplied by the refrigerant manufacturer
● European Union’s REACH database (Registration, Evaluation, Authorization and
Restriction of Chemicals)
