First-aid measures

Description of first aid measures

General advice: In the case of accident or if you feel unwell, seek medical advice


When symptoms persist or in all cases of doubt seek medical


Protection of first-aiders: No special precautions are necessary for first aid responders.

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


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)

Dry chemical

Unsuitable extinguishing media: None known.

Special hazards arising from the substance or mixture

Specific hazards during firefighting: 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: Hydrogen fluoride

carbonyl fluoride

potentially toxic fluorinated compounds

aerosolized particulates

Carbon oxides

Advice for firefighters

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

Use personal protective equipment.

Specific extinguishing methods: Use extinguishing measures that are appropriate to local circumstances

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


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 if advised by assessment of the local exposure


Advice on safe handling: Handle in accordance with good industrial hygiene and safety

practice, based on the results of the workplace exposure assessment

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


Avoid breathing gas.

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. 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


Acutely toxic substances and mixtures

Substances and mixtures with chronic toxicity

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 if advised by assessment

of the local exposure potential

Use with local exhaust ventilation.

Personal protective equipment

Eye protection : Wear the following personal protective equipment:

Chemical resistant goggles must be worn.


Hand protection

Material : Heat resistant gloves

Remarks: Choose gloves to protect hands against chemicals depending

on the concentration and quantity of the hazardous substance

and specific to place of work. For special applications,

we recommend clarifying the resistance to chemicals of the

aforementioned protective gloves with the glove manufacturer.

Wash hands before breaks and at the end of workday.

Breakthrough time is not determined for the product. Change

gloves often!

Skin and body protection : Wear the following personal protective equipment:

Flame retardant antistatic protective clothing, unless assessment

demonstrates that the risk of explosive atmospheres

or flash fires is low

Respiratory protection : Use respiratory protection unless adequate local exhaust

ventilation is provided or exposure assessment demonstrates

that exposures are within recommended exposure guidelines.

Filter type : Self-contained breathing apparatus

Protective measures : Wear cold insulating gloves/ face shield/ eye protection.

Stability and reactivity


Not classified as a reactivity hazard.

Chemical stability

Stable if used as directed. Follow precautionary advice and avoid incompatible materials and


Possibility of hazardous reactions

Hazardous reactions: May form explosive mixtures in air.

Can react with strong oxidizing agents.

Extremely flammable gas.

Hazardous decomposition products will be formed at elevated


Conditions to avoid

Conditions to avoid: Heat, flames and sparks.

Incompatible materials

Materials to avoid: Oxidizing agents

Hazardous decomposition products

Thermal decomposition: Hydrofluoric acid

Carbonyl difluoride

Carbon dioxide

Disposal considerations

Waste treatment methods

Product : Dispose of in accordance with local regulations.

According to the European Waste Catalogue, Waste Codes

are not product specific, but application specific.

Waste codes should be assigned by the user, preferably in

discussion with the waste disposal authorities.

Contaminated packaging : Empty containers should be taken to an approved waste handling

site for recycling or disposal.

Empty pressure vessels should be returned to the supplier. If not otherwise specified: Dispose of as unused product.
