Concentrated acids? Extremely strong oxidizing agents? Carcinogens? Stuff that intercalates with DNA? Mildly pathogenic bugs? Random sharps?

I respect all those things. But the lab activity that still makes me anxious is whenever we have to move the gas cylinders.

Nice post, argon is also very usefull on any spectroscopy where you need to use an ICP and sometimes even on gas cromatografy .

Yes, chain them to the wall!

These bottles have been known to propel themselves through concrete block walls.

I didn't know argon was above CO2 in atmospheric gases, but hey, after Nitrogen and Oxygen, everything is a mere fraction of a percent.

Haha this is one of the most classical "story". I am not sure if this really happened before, but probably expanding 200 bar of gas in a room(I assume close system) will definitely get all the windows broken

Well, on the TV show mythbusters they made that experiment, I don't remember what kind of gas they used (probably just air) or what pressure but it went trought a concret wall easy, it probably could be an interesting experience in a lab haha.
