Many researchers use CO2 from a fire extinguisher as the test gas for fluid dynamics and ventilation studies.

What types of demonstrations are they wanting to see?  Sulfur hexafluoride has the highest global warming potential of ANY chemical known to Man at 23,500 (CO2 = 1), which is why it’s been phased out of nearly every industrial process.  From a GWP/atmospheric perspective, consider that the loss of 42.6 g of SF6 is equivalent to 1 metric ton of CO2.  Just 42.6 g.  All that is to say whatever you decide to do, please be responsible.

Hello, everyone,

 

I have been tasked with investigating procedures for use of SF6 for lecture demonstrations. So I wanted to check in with you all to find out if you have any experience with supplying or supporting this demo and if so what tips, pointers, precautions, and/or prohibitions you might be willing to pass on.

 

Any help or info much appreciated, 

Thanks,
