First-aid measures

Inhalation - Remove patient from exposure, keep warm and at rest. Administer
oxygen if necessary. Apply artificial respiration if breathing has ceased or
shows signs of failing. In the event of cardiac arrest apply external
cardiac massage. Obtain immediate medical attention.

Skin Contact - Thaw affected areas with water. Remove contaminated clothing. Caution:
clothing may adhere to the skin in the case of freeze burns. After contact
with skin, wash immediately with plenty of warm water. If irritation or
blistering occur obtain medical attention.

Eye Contact - Immediately irrigate with eyewash solution or clean water, holding the
eyelids apart, for at least 10 minutes. Obtain immediate medical attention.

Ingestion - Unlikely route of exposure. Do not induce vomiting. Provided the patient
is conscious, wash out mouth with water and give 200-300 ml (half a pint)
of water to drink. Obtain immediate medical attention.

Further Medical Treatment - Symptomatic treatment and supportive therapy as indicated. Adrenaline
and similar sympathomimetic drugs should be avoided following exposure
as cardiac arrhythmia may result with possible subsequent cardiac arrest.

Fire-fighting measures

General - Extremely flammable.
Certain mixtures of HFCs and chlorine may be flammable or reactive
under certain conditions.

Extinguishing media - Allow gas fires to burn until exhausted.
Keep fire exposed containers cool by spraying with water.

Special hazards arising from the substance or mixture -
Combustion or thermal decomposition will evolve very toxic and corrosive
vapours. ( hydrogen fluoride )
Containers may burst if overheated.

Advice for firefighters - A self contained breathing apparatus and full protective clothing must be
worn in fire conditions.

Accidental release measures

Personal precautions, protective equipment
and emergency procedures -
Ensure suitable personal protection (including respiratory protection)
during removal of spillages.

Environmental precautions - Prevent liquid from entering drains, sewers, basements and workpits
since the vapour may create an explosive or suffocating atmosphere.

Methods and materials for containment and cleaning up -
Eliminate sources of ignition.
Provided it is safe to do so, isolate the source of the leak. Allow small
spillages to evaporate provided there is adequate ventilation.
Large spillages: Ventilate area. Contain spillages with sand, earth or any
suitable adsorbent material. Prevent liquid from entering drains, sewers,
basements and workpits since the vapour may create an explosive or
suffocating atmosphere.

Handling and storage

Precautions for safe handling -
Keep away from sources of ignition - No Smoking. Take precautionary
measures against static discharges.
Avoid inhalation of high concentrations of vapours. Atmospheric levels
should be controlled in compliance with the occupational exposure limit.
Atmospheric concentrations well below the occupational exposure limit
can be achieved by good occupational hygiene practice.
The vapour is heavier than air, high concentrations may be produced at
low levels where general ventilation is poor, in such cases provide
adequate ventilation or wear suitable respiratory protective equipment
with positive air supply.
Avoid contact between the liquid and skin and eyes.
Avoid venting to atmosphere.

Process Hazards -
Liquid refrigerant transfers between refrigerant containers and to and
from systems can result in static generation. Ensure adequate earthing.
Certain mixtures of HFCs and chlorine may be flammable or reactive
under certain conditions.
Care must be taken to mitigate the risk of developing high pressures in
systems caused by a temperature rise when liquid is trapped between
closed valves or in cases where containers have been overfilled.


Conditions for safe storage, including any incompatibilities -
Keep in a well ventilated place away from fire risk and avoid sources of
heat such as electric or steam radiators.
Avoid storing near to the intake of air conditioning units, boiler units and
open drains.

Exposure controls / personal protection

Occupational expousre limit - 1000 ppm LTEL (8 hr TWA) - Company Standard

Appropriate engineering controls - Provide adequate ventilation. Atmospheric levels should be controlled in
compliance with the proposed occupational exposure limit.

Personal protection equipment - Wear suitable protective clothing, gloves and eye/face protection.

Respirators -
In cases of insufficient ventilation, where exposure to high concentrations
of vapour is possible, suitable respiratory protective equipment with
positive air supply should be used.

Eye Protection -
Wear protective eyewear (goggles, face shield, or safety glasses).

Gloves -
Wear thermal insulating gloves when handling liquefied gases.

Stability and reactivity

Reactivity - See Possibility of hazardous reactions

Chemical stability - Stable under normal conditions.

Possibility of hazardous reactions - Certain mixtures of HFCs and chlorine may be flammable or reactive
under certain conditions. Incompatible materials: finely divided metals , magnesium and alloys
containing more than 2% magnesium . Can react violently if in contact
with alkali metals and alkaline earth metals - sodium , potassium , barium .
May react violently with oxidising agents.

Conditions to avoid - Keep away from heat and sources of ignition.
Incompatible materials - finely divided metals , alkali metals ( sodium , potassium ) , alkaline earth
metals ( barium , magnesium ) , alloys containing more than 2% magnesium

Hazardous decomposition products - hydrogen fluoride by thermal decomposition and hydrolysis.

Disposal considerations

Waste treatment methods - Best to recover and recycle. If this is not possible, destruction is to be in
an approved facility which is equipped to absorb and neutralise acid
gases and other toxic processing products.

Regulatory Information - Disposal should be in accordance with local, state or national legislation.
