Published in the 'Public Health Bulletin', No. 262, 1941, this historic image, which was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH) depicted a battery factory in which a respirator-wearing worker was in the process of 'finishing' metal storage battery plates. As a device containing both lead, a toxic heavy metal, and acid, in the form of sulfuric acid, batteries are potentially dangerous, both in their finished state, as well as during their manufacture. Precautions need be taken when building a battery, including the use of goggles, gloves, and filtered breathing devices. This worker was wearing the requisite filtered mask and protective gloves, but no goggles, which would have prevented accidental eye exposure to splashing fluids.
