4. FIRST AID MEASURES
Eye Contact
Ingestion
Contact with liquid or cold vapor can cause frostbite.
Immediately flush with water for at least 15 minutes, opening
eyelids to ensure flushing.
Get medical attention if symptoms occur.
Inhalation
Skin Contact
Victims should be assisted to an uncontaminated area is most
important.
Move exposed person to fresh air.
If not breathing, provide artificial respiration or oxygen by
trained personnel.
In the event of cardiac arrest apply external cardiac massage.
Further treatment should be symptomatic and supportive.
Keep victim warm and quiet.
PROMPT MEDICAL ATTENTION IS MANDAROTY IN
ALL CASES OF OVEREXPOSURE.
RESCUE PERSONNEL SHOULD BE EQUIPPED WITH
SELF-CONTAINED BREATHING APPARATUS.
Take off the contaminated clothing / shoes immediately.
Flush the affected area with lukewarm water not exceeds 105oF
(40oC) immediately.
Get medical attention if symptoms occur.
Unlikely route of exposure.
Do not include vomiting.
Provided the patient is conscious, wash out mouth with water
and give 200-300ml of water to drink.
Get medical attention if symptoms occur.

Special
chemical
High concentrations may cause asphyxiation.
Symptoms may include loss of mobility/ consciousness.
Victim may not be aware of asphyxiation.
As asphyxiation progresses, nausea, vomiting, prostration, and
loss of consciousness may result, eventually leading to
convulsions, coma, and death.
Use an extinguishing agent suitable for the surrounding fire.
Exposure to fire may cause containers to rupture/explode.
R134a does not support life. It act as a simple asphyxiant.
Special protective equipment and
precautions for fire fighters
In case of fire: Stop leak if safe to do so.
Continue water spray from protected position until container
stays cool.
In confined space use self-contained breathing apparatus (opencircuit positive pressure compressed air type) in combination
with fire kit.
Thermal decomposition will evolve very toxic and corrosive
vapors (hydrogen fluoride).
HFC 134a is not flammable in air under ambient condition of
temperature and pressure.
Certain mixtures of HFC 134a and air when under pressure
maybe flammable.
Certain mixtures of HFCs and chlorine may be flammable or
reactive under certain conditions.
Safety gloves and shoes, or boots, should be worn when
handling cylinders.

6. ACCIDENTAL RELEASE MEASURES
Personal precautions
Environmental precautions
Ensure suitable personal protection (including respiratory
protection) during removal of spillages.
Evacuate surrounding areas.
Keep unnecessary and unprotected personnel from entering.
If safe to do so: isolate the source of the leak.
Large spillages: Ventilate area.
Contain spillages with sand, earth or any suitable adsorbant
material.
Try to stop release.
Prevent from entering sewers, basements and work pits, or any
place where its accumulation can be dangerous.

Condition for safe storage
Precaution for safe handling
7. HANDLING AND STORAGE
Avoid inhalation of high concentrations of vapors.
Atmospheric level 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 vapor 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 with naked flames and hot surfaces as corrosive
and very toxic decomposition products can be formed. Avoid
contact between the liquid and skin and eyes.
Use only properly specified equipment which is suitable for this
product, its supply pressure and temperature.
Suck back of water into the container must be prevented.
Do not allow back feed into the container.
Contact your gas supplier if in doubt.
Never use direct flame or electrical heating devices to raise the
pressure of cylinder.
Valve protection caps must remain in place unless container is
secured with valve outlet piped to use point.
Do not drag, slide or roll cylinders.
Use a suitable hand truck for cylinder movement.
Use a check valve or trap in the discharge line to prevent
hazardous back flow into the cylinder.
Use a pressure regulator when connecting cylinder to lower
pressure piping or systems.
Avoid venting to atmosphere.
Keep away from ignition sources (including static discharges).
Do not allow the temperature where cylinders are stored to
exceed 125oF (520C).
Use a “first-in-first out” inventory system to prevent full
cylinders from being stored for excessive period of time.
Store in cool, dry, well-ventilated area of non-combustible
construction away from heavily trafficked areas and emergency
exits
Full and empty cylinders should be segregated.
Containers should not be stored in conditions likely to
encourage corrosion.
Container should be stored in the vertical position and properly
secured to prevent falling over.
Outside or detached storage is preferred.
Post “No Smoking” signs in use or storage areas.
There should be no accidental ignition in areas where this
product is being used or stored.
Avoid storing near to the intake of air conditioning units, boiler
units, and open drains.

- (1,1,1,2Tetrafluoroethane)
Appropriate
controls
Use local exhaust and general ventilation systems.
Engineering control measures are preferred to reduce oxygen depleted
atmospheres.
General methods include force-draught ventilation, separate from other
exhaust ventilation systems.
Ensure that sufficient fresh air enters at, or near, floor level.
Personal protection equipment
Wear goggles for eye protection.
Protective gloves made of any suitable material.
Contact lens should not be worn when working.
Wear suitable hand, body and head protection.
Do not eat, drink or smoke when using the product.
For emergency release use a positive pressure NIOSH approved air
supplying
respirator systems (SCBA or airline/escape bottle)
