Pure sulfur hexafluoride gas is non-toxic,but it has a small amount of product in the production process.Some of these products are highly toxic and must be purified to remove them completely before they can be used.

　　Although high purity gas is non-toxic,sulfur hexafluoride gas should be prevented from leaking in the workplace,resulting in a rapid rise in concentration.Once the gas leaks,it will do great harm.If the gas is not pure,it is not only harmful to the human body,but also corrosive to the electrical equipment,resulting in leakage.Therefore,it is very important to ensure the purity of the gas.

　　To detect gas purity,sulfur hexafluoride gas purity analyzer is generally used.There are different types and prices of high-purity sulfur hexafluoride purity analysis instruments on the market.Thermal conductivity method is the main method to detect gas purity.

　　When the concentration is too high,it will suffocate people,so sulfur hexafluoride gas production sites must take this situation into account when designing indoor ventilation devices.The gas also mixes with air by convection.

　　In addition,once high purity sulfur hexafluoride is mixed with air,it will form a mixture of gases,which will not be separated again.Under the action of the electric arc,it will also produce highly toxic decomposition,they are also strongly corrosive.
