So this powder coating company i used to work for has a fan to pull air through the building. Issue is a good bit of the powder the dust collector misses just blows out the building and onto the cornfeild behind the building.
I quit due to bad safety, i wasnt informed i was useing hydrofloric acid in the wash tanks, no msds, lots of powder floating arround waiting for a spark, and the worst part was the boss made the employees pay for drinkable water.
He poluted the water table (ground water) badly near his business with iron + the water was shit in the area to start with
