Hi all, I've been working at UPS for 8 years as a package handler (Portland, OR). Every day after work I've had black snot. So: Does this happen to everybody? Is this bad for you? If so, how bad? Though the effects of this may be difficult to measure, has anyone had any health problems that they think may be in part attributable to this (e.g. respiratory problems). Does anybody know of any regulations UPS is supposed to comply with regarding the amount of dust allowable in the hub? Any feedback regarding this issue would be greatly appreciated.
