I’m not so worried about an explosion. Those are rare. What is certain is the noise (equipment moving and processing the grain, and then there are the heavy trucks; all easily audible inside our well insulated, masonry construction house; and it’s 24/7 during harvest) and the dust (more like red snowflakes) — it can be as much as 1/4” covering everything in a day or two if the wind is “right”. Not only is it a mess, there are potential health implications too, such as allergies from repeated exposure, etc.
They shouldn’t put those near residential areas. I have an acquaintance who had a coal-fired plant go up near him, and he was able to force the power company to buy him out at a nice profit.
