I worked in a Chromate plant back in the 70s. Luckily I only worked in the adjacent buildings but the Chromate workers had constant nose bleeds. Chromate dust will eat the septum (the membrane that separates the nostrils/sinuses). Those guys would brag about there green arms (stained green by the cromate pellets that they handled). I stayed as far as I could from that place even though I was assigned to that building every now and then. We would line up and load railroad cars full of 90 lb chromate bags. I tried to explain to the older workers that chromate was cancerous but they would just laugh. They would show off by digging their arms in barrels of Chromate pellets. Their arms would be stained green, then they would say, "You see this stuff is completely safe". I felt sorry for them and their lack of knowledge.
