Does anyone know if our package cars have noise and dust regulations? My package car sucks so much dust inside the cab that I can't breath. I close all doors, shut all vents, and still have dust so thick in the cab, it can be hard to see. I came down with a upper and lower respiratory infection last week, and I am still fighting it. The package car rattles and squeaks very loud also. I have put tape on door jams, guides, and metal to metal contact points, and it has quieted it down a little. Yes I have a country route with many backroads. I drive around 200 miles daily. My ears ring a lot of days when I get home. I forsee retiring with hearing aids, oxygen, artificial knees, a wheelchair, etc. I am grateful for my job at UPS, but know that it is slowly sucking the life out of my worn out body.
