First-aid measures

General advice: In the case of accident or if you feel unwell, seek medical advice immediately.
When symptoms persist or in all cases of doubt seek medical advice.
Protection of first-aiders: No special precautions are necessary for first aid responders.
If inhaled: If inhaled, remove to fresh air. Get medical attention if symptoms occur.
In case of skin contact : Thaw frosted parts with lukewarm water. Do not rub affected area.Get medical attention immediately.
In case of eye contact : Get medical attention immediately.
If swallowed : Ingestion is not considered a potential route of exposure.

Most important symptoms and effects, both acute and delayed
Risks : Contact with liquid or refrigerated gas can cause cold burns and frostbite.

Indication of any immediate medical attention and special treatment needed
Treatment : Treat symptomatically and supportively.

Fire-fighting measures

Extinguishing media
Suitable extinguishing media : Water spray, Alcohol-resistant foam, Carbon dioxide (CO2)
Unsuitable extinguishing media : Dry chemical

Special hazards arising from the substance or mixture :
Specific hazards during fire-fighting : May form explosive mixtures in air.
Exposure to combustion products may be a hazard to health.
If the temperature rises there is danger of the vessels bursting due to the high vapor pressure.

Hazardous combustion products : Carbon oxides .Silicon oxides. Formaldehyde

Advice for firefighters
Special protective equipment for firefighters : Wear self-contained breathing apparatus for firefighting if necessary. Use personal protective equipment.

Specific extinguishing meth-ods : Use extinguishing measures that are appropriate to local cir-cumstances and the surrounding environment.
Fight fire remotely due to the risk of explosion.
Use water spray to cool unopened containers.
Leaking gas fire: Do not extinguish, unless leak can be stopped safely.
Remove undamaged containers from fire area if it is safe to do so.
Evacuate area.

Accidental release measures

Personal precautions, protective equipment and emergency procedures
Personal precautions : Only trained personnel should re-enter the area.
Remove all sources of ignition.
Avoid skin contact with leaking liquid (danger of frostbite).
Ventilate the area.
Follow safe handling advice and personal protective equipment recommendations.

Environmental precautions : Prevent further leakage or spillage if safe to do so.
Retain and dispose of contaminated wash water.

Methods and material for containment and cleaning up
Methods for cleaning up : Ventilate the area.
Non-sparking tools should be used.
Suppress (knock down) gases/vapours/mists with a water spray jet.
Local or national regulations may apply to releases and disposal of this material, as well as those materials and items employed in the cleanup of releases. You will need to determine which regulations are applicable.

Handling and storage

Precautions for safe handling
Technical measures : Use equipment rated for cylinder pressure. Use a backflow preventative device in piping. Close valve after each use and when empty.

Local/Total ventilation : Use with local exhaust ventilation.Use only in an area equipped with explosion proof exhaust ventilation.

Advice on safe handling :
Avoid breathing gas.
Handle in accordance with good industrial hygiene and safety practice.
Keep container tightly closed.
Wear cold insulating gloves/ face shield/ eye protection.
Prevent backflow into the gas tank.
Open the valves slowly to prevent pressure surges.
Close valve after each use and when empty. Do NOT change or force fit connections.
Prevent the intrusion of water into the gas tank.
Keep away from heat and sources of ignition.
Take precautionary measures against static discharges.
Take care to prevent spills, waste and minimize release to the environment.

Hygiene measures : Ensure that eye flushing systems and safety showers are located close to the working place. When using do not eat, drink or smoke. Wash contaminated clothing before re-use.

Conditions for safe storage, including any incompatibilities
Requirements for storage areas and containers :
Keep in properly labelled containers. Store in original container. Keep tightly closed. Keep in a cool, well-ventilated place. Keep away from direct sunlight. Store in accordance with the particular national regulations. Keep away from heat and sources of ignition.

Advice on common storage:
Do not store with the following product types:
Self-reactive substances and mixtures
Organic peroxides
Oxidizing agents
Flammable liquids
Flammable solids
Pyrophoric liquids
Pyrophoric solids
Self-heating substances and mixtures
Substances and mixtures, which in contact with water, emit flammable gases
Explosives
Acutely toxic substances and mixtures
Substances and mixtures with chronic toxicity

Specific end use(s)
Specific use(s) : These precautions are for room temperature handling. Use at elevated temperature or aerosol/spray applications may require added precautions.
For further information regarding the use of silicones / organic oils in consumer aerosol applications, please refer to the guidance document regarding the use of these type of mate-rials in consumer aerosol applications that has been devel-oped by the silicone industry (www.SEHSC.com)

Exposure controls / personal protection

Engineering measures
Processing may form hazardous compounds (see section 10).
Minimize workplace exposure concentrations.
Use only in an area equipped with explosion proof exhaust ventilation.
Use with local exhaust ventilation.

Personal protective equipment
Eye protection : Wear the following personal protective equipment:
Chemical resistant goggles must be worn.
Face-shield

Hand protection
Remarks : Choose gloves to protect hands against chemicals depend-ing on the concentration and quantity of the hazardous sub-stance and specific to place of work.
