One of the cooling traps (for a large diffusion pump, at lab) employed recirculating 1,1,1-trichloroethane, with chunks of dry ice; this is among the least toxic of the chlorocarbons, most often used in degreasing and related. It's what the Fucking Army could/ should/ have used all along - the smarmy iggerant Bastards.

It was Common Knowledge (at the lab, fershure..) *DECADES ago* that: Trichloroethylene is UGLY [long list...] I recall pointed discussions underlining the Necessity of there being no 'name confusion' re replenishing such compounds - we notified All the troops. And checked.

(One can find 100Ks of hits in the usual places, re its toxicity to humanoids -
(except, perhaps, for modern-day reptilian-humanoids?))

As usual The Army is baldface Lying. A Nation with lots of Scum in Authority.
This Lie is ~ as transparent as the fact that Shrub and the neoconmen led a whole nation of feckless consumers down that so artlessly-contrived, primrose path - direct to the Tar Baby in the glen, to which all are now Stuck.

Facts don't matter no mo / we died psychically at about the time of Greed is Good! IIRC.



{Shrug} - add it to the mountain of BS du jour, I guess :-/
I don't even keep score anymore.. Augean Stables.
Generations couldn't un-do this recent and massive, premeditated dismantling IMO. So why worry?
