I understand that, but people who are 200 miles down range from this kind of thing aren’t going to be exposed to significant acidity from that plume. If for some reason it is an issue, sure, get the dual acid gas/organic (I’ve got an old school one that stacks cartridges or takes mixed hazard cartridges). This plum isn’t anything much worse than one one of the volcano level tire fires they’ve had out here in the past though and it appears that “click baiters” are milking this and other similar events like late morning cows...
...so easily panicked.
Did you see this unrolled thread? I would like to know what you think of it, lots of technical info beyond my pay grade, but it seems that the thing isn’t as bad as many are portraying.

Based on my preliminary research, the derailed train of Vinyl Chloride is going to be something of a short term calamity with hopefully few long term effects. Apart from the cause of the derailment most everything else makes sense.
