Description:
1. Toxicity
Maximum allowable concentration: 10ppm (12mg / m3)
Sulfur hexafluoride is physiologically inactive and is
pharmacologically considered an inert gas. But when it contains
impurities such as SF4 will become toxic substances. When inhaled
high concentrations of SF6 may appear dyspnea, wheezing, skin and
mucous membranes turn blue, systemic spasms and other symptoms of
asphyxia.
2. Security
Gas device leak detection with soap. SF6 non-corrosive, you can use
stainless steel, copper, aluminum and other common materials. Fire
and sand can be used to extinguish fire. The leaking gas can be
introduced into a mixed solution of caustic soda and hydrated lime,
or the leaked cylinder can be placed in a fume hood.

Applications:
Electrical Industries Circuit Breaker | leak detection and as a gaseous dielectric for transformers,
condensers |
As an inert gas | For the casting of magnesium.as an etchant in the semiconductor |
As an inert filling | Insulated glazing windows. |
Dielectric medium | SF6 is used in the electrical industry as a gaseous dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment, often replacing oil filled circuit breakers (OCBs) that can contain harmful PCBs. |
Medical use | SF6 is used to provide a tamponade or plug of a retinal hole in retinal detachment repair operations in the form of a gas bubble.SF6 is used as a contrast agent for ultrasound imaging. Sulfur hexafluoride microbubbles are administered in solution through injection into a peripheral vein. |
Tracer compound | Sulfur hexafluoride was the tracer gas used in the first roadway air dispersion model calibration; this research program was sponsored by the U.S. Environmental Protection Agency and conducted in Sunnyvale, California on U.S. Highway 101.Sulfur hexafluoride is also routinely used as a tracer gas in laboratory fume hood containment testing. |
