On hearing this story, a man hired as a corporate industrial hygienist, tasked with sampling acid mist in the battery-charging area in a Ford battery plant, recounted this: “To set up the air monitors, I had to wear a respirator. Staff asked me to take it off since it might make workers who saw me with it on worry about the ill effect of the air on them. But they needn’t have worried. Some of the guys started to taunt me, the corporate sissy who couldn’t tough it out like they [did]. But when they laughed at me, I could see their teeth were visibly eroded by exposure to sulfuric acid mist.”
