I might be remembering the name wrong, but I was doing engineering work for a large scale grain silo, tablets of phosgene was used as fumigation agent to kill the bugs and whatnot. Nasty stuff. There was a small spill in a semi-confined area, unaware workers inhaled a little (no mask) and got sick. Reason? The lazy bastard who was supposed to go on top of the silo to put some amount every once in a while while conveyors are filling it, decided to go and dump into conveyors before the grain elevators. There was an overload, elevators stalled, workers had to open the lids to empty it with shovels. To this day I hate that sob.

[@joeylawn36111]

May have been instead something like aluminum phosphide, a solid, which decomposes via moisture into a similar-named gas called Phosphine (PH3). Phosgene (COCl2) is a gas itself, so it would not be in tablet form. Phosphine and phosphine releasers are used in fumigating grain.

[@reinisaugustins8555]

You were using phosphine (PH3), also known as hydrogen phosphide or phosphorus trihydride, not phosgene (COCl2), also known as carbonic chloroanhydride or chloroformaldehyde. These are completely different gases. Phosgene is not used as a fumigant, but phosphine, although controversial due to many poisoning deaths, is a popular fumigant, especially for grain.
