It has an atmospheric life of 3,200 years and global warming potential 23,900 times stronger than carbon dioxide. SF6 is considered one of the most dangerous greenhouse gases known. It is banned as a tracer gas and is limited to high voltage applications. In addition, the US Department of Energy repaired leaks in several laboratories, thereby reducing emissions by 35,000 pounds a year.
The major greenhouse gases (GHGâs) solely responsible for greenhouse effect are Carbon dioxide, Ozone, Methane and Water vapor. Although these gases comprise 1% of our atmosphere, they act like a thick warm blanket outside that surrounds this planet and regulate climate control. Greenhouse effect is not bad.
