CO2 as an Inert Gas - CR4 Discussion Thread· CO 2 is emphatically not explosive. If you like it has already "exploded" when carbon reacts with oxygen to give CO 2 plus lots of heat. So CO 2 is inert in that sense. The only elements that might react with CO 2 are those that have an even greater affinity for oxygen than carbon, such as magnesium, sodium, potassium. Flushing a container with car exhaust seems a bit crude, but as long as he ...[email protected]

Switchgear - Wikipedia switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
