Since the Kyoto Protocol of 1997, there have been discussions of measures that aim to reduce emissions of SF 6. One example is the voluntary commitment within the industry in Germany. On the European level, a ban on specific instances of use was discussed in 2014 in the context of the F-gas Regulation (EU, No. 517/2014), but ultimately rejected.

What Is gaz sf6? and How Is It used?Is sf6 gas A Danger to Human Health?How Environmentally Damaging Is It?Has The Environmental Impact Even Been Underestimated?Is The Mitigation of sf6 gas Emissions Difficult? Do Better Solutions Exist?Conclusiongaz sf6 is a long-lived, highly potent greenhouse gas. It is manmade and combines excellent electrical properties with chemical stability and low toxicity. Moreover, It’s non-flammable and low in cost. These characteristics have led to its widespread and enthusiastic adoption by the electrical industry, which uses approximately 80% of all Sulfr hexafluorideproduced (Powell, 2002: 6). Within the electrical industry insulating gasis used as an insulating medium for medium (MV) and high (HV) voltage electrical switchgear. A switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate sections of electrical grids. Low-voltage (LV) switchgear are used for controlling electrical circuits within buildings, medium voltage (MV) switchgear for controlling the electrical grids within cities and towns, and high voltage (HV) switchgear for grids that span a greater geographical area such as countries and regions.

For sound insulation in windows, In vehicle tyres, Is Sulfr hexafluoride a health hazard? Pure sf 6 is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is gaz sf6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. What is the overall contribution of sf6 gas used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE).
