I guess one could theoretically add anything they wanted; but if it's not on location; why the chemistry lessons?

There is [was!] a rail line running past the plant. Had a loaded LP or chlorine tanker [circa 20K gallons and frequently travelling in multi-car *blocks*] been travelling past when the plant went up, the entire town would be pretty much gone. Think a blast four to eight times the size of what happened, with the high school and triage area also gone.

And instead of the town's hospital [about 1200 feet away from the blast ground zero] being seriously damaged, it would likely have been leveled.
