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.
