Guidance on Safe Use

First-aid measures

Inhalation

High concentrations may cause asphyxia. Symptoms may include loss of ability to move and loss of consciousness. Victims are not aware of asphyxia

Can cause headache, nausea and irritation of respiratory organs. Victims must be brought into the fresh air using a respiratory device with an

atmosphere-independent air supply. Keep victims warm and quiet. Consult a physician immediately. Artificial respiration in case victim stops

breathing.

Eye contact

Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.

Ingestion

Ingestion by swallowing is not considered a possible mode of exposure.

Fire-fighting measures

Suitable extinguishing media

water spray, dry powder

Extinguishing media which must not be used for safety reasons

carbon dioxide (CO2)

Specific hazards during fire fighting

Outflowing, ignited gas cannot be extinguished.

Stop gas leak if this can be done at no risk.

Cool container with jet of water spray from a safe distance

Extinguish all other flames.

Special protective equipment for fire-fighters

In the event of fire, wear self-contained breathing apparatus.

Further information

Do not quench escaping gas, since an explosion-like recombustion is possible.

Accidental release measures

Personal precautions

Leave room immediately.

Alert all persons!

Close off the danger area with a wide security zone, stay up wind of any gas leak in the open air.

Dispose of ignition sources.

Ensure sufficient ventilation.

Environmental precautions

Stop gas leak if this can be done at no risk.

Prevent substance from entering sewers, cellars, trenches, pits or other places in which a collection of gas could be dangerous

Handling and storage

Safe handling advice

Use only explosion-proof equipment.

Prevent water from entering the gas container.

Carefully flush clear and render inert before working on containers and lines.

Prevent reflux into the gas container.

Use only equipment that is suitable for use with this product at the prescribed pressure and temperature.

Consult supplier in case of doubt.

Advice on protection against fire and explosion

Take precautionary measures against static charges, keep away from sources of ignition.

Explosion protection equipment required.

Storage

Requirements for storage areas and containers

Store gas container and pressurized gas bottles in a cool and well-ventilated place

Observe special instructions applicable to compressed gases.

Max. storage temperature: < 50'C.

Advice on common storage

Keep away from, and do not store with, oxidants and burnable substances

Exposure controls / personal protection

Components with workplace control parameters

CAS-No.       7803-62-5       EC-No. 232-263-4

Control parameters       0.5 ppm

                                                    0.67 mg/m3              Time Weighted Average (TWA):(EH40 WEL)

Control parameters

                                                     1 ppm

                                                     1.3 mg/m3              Short Term Exposure Limit (STEL):(EH40 WEL)

Engineering measures

If possible, use material transfer/filling, metering and blending plants that are closed, or provide for local suction devices.

Priority should be given to closed-system units.

Personal protective equipment

Respiratory protection

In case of dusts/vapours/aerosols being formed or if the limit values like TLV are exceeded:

use respiratory equipment with suitable filter or wear a self contained respiratory apparatus

Hand protection

Use leather gloves as a protection against injury from handling pressurised gas cylinder or from freezing as a result of rapidly evaporating gas.

Eye protection

close-fitting protective goggles (e.g. closed goggles)

Stability and reactivity

Hazardous reactions

May show strong reactions with oxidizable substances. Autocombustible in the open air (fire cannot be extinguished). May form spontaneously

combustible, highly explosive mixtures with air. May form an explosive mixture with air. Exposure to fire can cause the container to burst / explode.

Ouflowing gas cannot be extinguished.

Disposal considerations

Product

Do not release at locations at which there is a risk that an explosive gas/air mixture will form. Burn off unused gas with a suitable burner equipped

with a flashback arrester only. Wash combustion gas with water to precipitate silicon dioxide. Do not release into sewers, cellars, workpits and

other locations where collection of the gas might cause a hazard. Consult gas supplier concerning any problems.
