Tips: Hazards of Sulphur Hexafluoride (SF6)

Health Risks:

• Asphyxiation: SF6 is a dense gas and can displace oxygen in confined spaces, leading to a risk of asphyxiation. In high concentrations, it can cause dizziness, unconsciousness, and even death due to lack of oxygen.
• Inhalation: Although SF6 is generally considered non-toxic, inhaling high concentrations can cause respiratory issues and potential harm due to oxygen displacement.

Environmental Impact:

• Greenhouse Gas: SF6 is a potent greenhouse gas with a global warming potential (GWP) 23,500 times greater than carbon dioxide (CO2) over a 100-year period. It has a long atmospheric lifetime of about 3,200 years, contributing significantly to global warming and climate change.
• Persistence: SF6 is highly stable and can remain in the atmosphere for thousands of years, making it a long-term environmental pollutant.
