Sulfur Hexafluoride (Elegaz)
Sulfur hexafluoride (SF6), also known as Elegaz, is a colourless, odorless, non-flammable, and non-toxic gas SF6 is primarily used in the electrical power industry as a gaseous dielectric medium for high-voltage sulfur hexafluoride circuit breakers, switchgear, and other electrical equipment, often replacing oil-filled circuit breakers that can contain harmful polychlorinated biphenyls (PCBs). SF6 is also used as a contrast agent in medical imaging to improve the quality of an ultrasound. SF6 is generally transported as a liquefied compressed gas.

Information for the User about Sulfur Hexafluoride
➤ Electrical Industry:
Widely applied as an insulating gas in high-voltage apparatus like circuit breakers, transformers, and switchgear.
➤ Medical Imaging:
Serves as a contrast agent in ultrasound imaging and functions as a non-reactive tracer for pulmonary function tests.
➤ Industrial Applications:
SF6 proves instrumental in industries necessitating inert and non-reactive environments, including casting and magnesium production.
Handling by proficient experts is imperative to prevent inadvertent emissions. Adequate ventilation is critical during SF6 usage to avert confined space buildup.
While non-toxic, Sulfur Hexafluoride is recognized as a potent greenhouse gas. Caution is paramount due to its air-displacing capability, which may lead to oxygen deficiency.
Ensure cylinders are stored in well-ventilated areas, away from incompatible substances. Adhering to specified storage guidelines guarantees the gas's stability and safety.
