"The affected plant houses chemicals known to cause “acute toxicity, carcinogenicity, and reproductive toxicity, and may cause serious eye damage or eye irritation, skin corrosion or irritation, aspiration hazard, and organ toxicity.”

Was this an "oops" some did something wrong?
Was it planned like East Palestine Ohio?
Was it a terrorist group that our government let in across the border?
