Sulfur hexluoride;

CAS no :2551-62-4

EINECS:219-854-2

molecula , r formula:SF6

molecular weight:146.06

density:6.602;1.88 (-50.8℃, liquid)

Melting point: -50.5

properties :colorless, tasteless, odorless, non-toxic inert non-combustion gas.

Slightly soluble in water, alcohol and ether, soluble in potassium hydroxide.

purpose: used in high voltage switch for arc extinguishing and large capacity
transformer insulation material;It can also be used in particle accelerator and
lightning arrester.It can be used as refrigerant in industry because of its
chemical stability and non-corrosion to equipment.Also used in reflexes because of
its high ability to stop alpha particles;It also ACTS as a reverse adsorbent to
replace oxygen from mine coal.

Obtained by the direct combination of elemental fluorine and sulfur.

[note] a substance with good chemical stability, thermal stability is still very
good above 500℃.Sublimation temperature -63.8℃.

Folding first aid measures

Inhalation: quickly get out of the scene to the fresh air. Keep the respiratory
tract open. If breathing is difficult, give oxygen. If breathing stops, do
artificial respiration immediately. Seek medical treatment.



Folding fire protection measures

Dangerous characteristics: in the event of high heat, the internal pressure of the
vessel increases, there is a risk of cracking and explosion.

Hazardous combustion products:sulfur oxide and hydrogen fluoride.

Fire-extinguishing method: The product is non-combustible. Cut off the air supply.
Spray water to cool the container and, if possible, move the container from the
fire field to the open position.



Folding leakage emergency treatment



Emergency treatment: quickly evacuate the personnel of the leaking pollution area
to the upper hand and conduct the isolation, and strictly limit the access. It is
recommended that the emergency treatment personnel wear self-contained positive
pressure breathing apparatus and wear general working clothes. Cut off the source
of leakage as much as possible. Reasonable ventilation and accelerated diffusion.
If possible, use it immediately. The air leakage container shall be properly
handled, repaired and inspected for reuse.



Folding disposal and storage

Operating precautions:closed operation, local exhaust. Operators must be specially
trained and strictly comply with the operating procedures. It is recommended that
the operator wear a filter gas mask(half mask). Keep away from flammable and
combustible materials. Prevent gas from leaking into the workplace air. Avoid
contact with oxidant. Handle gently to prevent damage of steel cylinders and
accessories. Equipped with leakage emergency handling equipment.



Storage precautions: Store in a cool and ventilated warehouse. Keep away from the
fire and heat. The temperature of the reservoir should not exceed 30 ℃. It shall
be stored separately from the combustible substance and the oxidizing agent, and
the mixed storage shall be avoided. The storage area shall be provided with a
leakage emergency treatment equipment.
