4. FIRST AID MEASURES
Eye Contact
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.
Page 4 of 15
Inhalation
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.
Skin Contact
Take off the contaminated clothing / shoes immediately.
Flush the affected area with lukewarm water not exceeds 105oF
(40oC) immediately.
Do not use hot water.
If warm water is not available, gently wrap affected parts in
blankets.
Get medical attention if symptoms occur.
Ingestion
Unlikely route of exposure.
Do not include vomiting.
Get medical attention if symptoms occur.
Most important symptoms and effects,
both acute and delayed
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.
Contact with liquefied gas may cause frostbite.

5. FIRE FIGHTING MEASURES
Suitable extinguishing media
Alcohol-resistant foam.
Carbon dioxide (CO2).
Dry Chemical.
Unsuitable extinguishing media
Water Jet.
Special hazards arising from the
chemical
Exposure to fire may cause containers to rupture/explode.
Vapor is heavier than air, may travel long distances along the
ground before reaching a source of ignition and flashing back.
When mixed with air and exposed to ignition source, vapors
can burn in open or explode if confined.
Sustained fire attack on vessels may result in a boiling liquid
expanding vapor explosion (BLEVE).
DO NOT direct water at source of leak or pressure relief
devices, icing may occur.
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.
Safety gloves and shoes, or boots, should be worn when
handling cylinders.
Vapors may form explosive air mixtures even at room
temperature.
Prevent buildup of vapors or gases to explosive concentrations.
Water runoff can cause environmental damage.

6. ACCIDENTAL RELEASE MEASURES
Personal precautions
Ensure suitable personal protection (including respiratory
protection) during removal of spillages.
Evacuate surrounding areas.
Ensure adequate ventilation.
Keep unnecessary and unprotected personnel from entering.
Beware of vapors accumulating to form explosive
concentrations.
Vapors can accumulate in low areas.
Environmental precautions
If safe to do so: isolate the source of the leak.
Try to stop release.
Prevent from entering sewers, basements and work pits, or any
place where its accumulation can be dangerous.
If the product contaminates rivers and lakes or drains inform
respective authorities.
7. HANDLING AND STORAGE
Precaution for safe handling
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

7. HANDLING AND STORAGE
Precaution for safe handling
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 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.
Condition for safe storage
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.
Electrical installations / working materials must comply with
the technological safety standards.
Do not store with oxidizers.
