Sulphur hexafluoride (SF6) is a synthetic (i.e., human-made) gas that is colourless, odorless, non-toxic (except when exposed to extreme temperatures), and non-flammable. It is heavier than air and hence stays close to the ground upon release which can cause death by suffocation if large quantities are involved.

Is sulfur hexafluoride safe to breathe in?
* Breathing Sulfur Hexafluoride may irritate the lungs causing coughing and/or shortness of breath. Higher exposures can cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency, with severe shortness of breath.
Is SF6 harmful to humans?
Sulfur hexafluoride (SF6) is a relatively nontoxic gas used in a number of applications for its inert qualities.
What is sulfur hexafluoride used for?
Sulfur hexafluoride (SF6) /is/ used as an electrical insulating material in circuit breakers, cables, capacitors, and transformers.
What does SF6 smell like?
Toxicity. FAULTED SF6 GAS – Faulted SF6 gas smells like rotten eggs and can cause nausea and minor irritation of the eyes and upper respiratory tract. Normally, faulted SF6 gas is so foul smelling no one can stand exposure long enough at a concentration high enough to cause permanent damage.
What gas makes your voice deep?
Sulfur Hexafluoride (SF6)
The Deep Voice Gas – Sulfur Hexafluoride (SF6) – Steve Spangler Science.
Where can I buy sulfur hexafluoride to inhale?
Where can you buy Sulfur Hexafluoride? SF6 is an industrial gas so it must be purchased from a medical, welding or industrial gas provider. We purchase ours at NORCO which is a welding and medical supplier in the United States. We would recommend calling local gas providers and seeing if they can order it for you.
Why is SF6 bad for the environment?
Protect the Environment – SF6 is the most potent greenhouse gas known. It is 22,800 times more effective at trapping infrared radiation than an equivalent amount of CO2 and stays in the atmosphere for 3,200 years.
Is SF6 used in electric cars?
SF6was widely adopted as an alternative to oil and air for insulating mid- and high-voltage electrical equipment. Around 80% of all SF6 produced worldwide is used in the electric power industry. SF6 is used in gas-insulated switchgear for wind turbines to prevent overloading and short-circuiting.
When was SF6 banned?
The European Commission has proposed that SF6, a fluorinated greenhouse gases with a potency 25,000 times that of carbon dioxide, be banned from new electrical equipment as of 2031, as part of a broader tightening of limits on F-gases.
Is sulfur hexafluoride gas flammable?
The material safety data sheet (MSDS) for SF6 indicates that it is non-combustible and non-flammable.
What is sulfur hexafluoride made from?
Sulfur hexafluoride is a sulfur coordination entity consisting of six fluorine atoms attached to a central sulfur atom.
Does sulfur hexafluoride make your voice deeper?
Sulfur Hexafluoride is an inert gas that is known to be six times heavier than the air we breathe. While Helium being lighter makes our voice higher, SF6 makes our voice deeper. The sound travels slower in denser gases which is why our voice will come out deeper and rather slow.
Why does sulfur hexafluoride not dissolve in water?
In sulfur hexafluoride, the sulfur atom is shielded by six fluorine atoms which impede kinetically any reaction with water, alkali hydroxides, ammonia or strong acids; as a result it remains inert to these reagents.
How much SF6 is in a circuit breaker?
Working of SF6 Circuit Breaker
The working of an SF6 circuit breaker is similar to the working of a normal circuit breaker we discussed in previous articles. In the closed position of the breaker, the contacts remain surrounded by sulphur hexafluoride gas (SF6) gas at a pressure of about 2.8 kg/cm2.
What is the heaviest non toxic gas?
Sulphur hexafluoride (SF6)
How can I naturally deepen my voice?
Try speaking through your mouth, rather than your nose. It’s possible to get a deep nasal voice, but it sounds more masculine if you speak through your mouth. To deepen your voice, you’ll want to try and lower your pitch. To do this, relax your throat as much as possible, to avoid tightening your vocal cords.
How do you make sulfur hexafluoride?
Preparation: Sulfur hexafluoride is synthesized by expositing elemental sulfur (crystal solid S8) and elemental fluorine (gas F2) at 300 ºC. After the reaction finishes, the SF6 is purified by heating or alkali washing to remove other SxFy gases.
Where do you find sulfur hexafluoride?
There are no natural sources of sulfur hexafluoride; it originates entirely from human activities. It has a very long atmospheric lifetime.
How much worse is SF6 than CO2?
23,500 times
SF6 is a manmade gas with a global warming potential (GWP) 23,500 times greater than CO2, and a lifespan of 3,200 years in the atmosphere. Every new particle we leak is there to stay, a thick atmospheric blanket warming the earth for more than 100 generations.
Is SF6 ozone depleting?
15,16 The relative contribution of SF6 to global warming is estimated at the present time to be only 0.01%, and unlike other environ- mental pollutants, there is no evidence that SF6 contrib- utes to stratospheric ozone depletion.
