Everyone keeps getting worked up about how the burn off made hydrochloric acid in the atmosphere; is that really worth worrying about compared to the vinyl chloride itself and whatever other byproducts came off the burn? Like, HCL isn't carcinogenic. I have no chemical training to speak of, but I can buy a gallon of muriatic acid at the hardware store. My gut instinct is that I'd rather stick my hand in a beaker full of HCL than be in the same room with any visible quantity of vinyl chloride.

It is unlikely that HCL would have rained on anyone other than the residents in nearby Palestine. The most up to date measurements of atmospheric concentrations of the plume that escaped from the fire show insignificant concentrations of acid rain forming chemicals such as HCL.

I will say that if you are a resident of Palestine, don't go out playing in rain any time soon, but otherwise there isn't too much to worry about down wind.

What other byproducts would you expect to find in the burn plume? Obviously it isn’t an ideal way to incinerate chemicals. They can’t be getting complete combustion.

Phosgene gas a chemical weapon used in WWI is also a potential byproduct but I am unsure of the quantity that would be generated. It appears that those involved are aware of the potential and are monitoring those levels as well. I don't currently see any data that suggest that phosgene gas is of immediate concern but that may change with more data. If it is an issue it would have likely dissipated by now and may only be an issue in the upper atmosphere. I have never dealt with phosgene gas so I am not super confident on how it interacts or dissipates in the environment.
