BAM...that's what I was looking for! Thanks for your insight.
What I am most concerned about is my workplace, where there is constantly DPFs coming apart for troubleshooting or preventative maintenance purposes. I purchased good respirators for everyone in the shop a few years back, but there nothing to stop soot from drifting to other bays where people are not wearing their respirators. Also, with a prevalent mentality that DPF engines are "clean as clean can be", some of my colleagues are lazy when it comes to using the shop exhaust fans while running trucks indoors. I know too many diesel mechanics that died from cancer.
Diesel engine exhaust stinks. Period. Old diesels and new diesels alike, to varying degrees. Chances are, if something offends your nose, it's probably not the greatest for you.
