This study presents the risks generated by the use of the alternative gases to SF 6 for people working on medium voltage electrical equipment or close to these apparatus and the precautions to be taken in order to ensure the safety of people. The acute toxicity of fluoronitrile and fluoroketone being more important than the SF 6, more precautions must be taken in order to ensure the safety of people in case of gas leakage. On the other hand, the level of toxicity of HFO1234zeE is similar to SF6 and precautions to be taken are then same as for SF6.
