This was vapour - but it was being forced through a small smace.
But using a 55 gallon (205L) steel vessel with the top removed means a surface area of 163 cm2 of diethyl ether (vapor pressure 379.6) or THF (vapor pressure 127) - VP at 20C.
I guess that is one reason why THF is preferred. On the other hand, water is miscible with THF which is bad for a Grignard. Swings and roundabouts.
Above is a police bust of a small PCP lab. But I've read of a couple of lab busts in 2016. One burnt down, the other was detected because neighbours complained about the constant odour of chemicals. In both cases their were dozens of 55 gallon drums and in the one that was dismantled, they were using the drums as reaction vessels....
Sheer madness.
Dutch law actually make an unsafe lab a separate crime so even if you were making something legal, they still close you down, take all your stuff and throw you in jail and/or give you a huge fine.
