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 workers were in the process of assembling storage batteries. These men were working at a battery plate cleaning station, where they would scour the metallic plates used in the composition of lead acid batteries. 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. These workers were wearing filtered masks, but no goggles, and it could not be determined if any of the men were wearing gloves, which would have prevented accidental eye, or dermal exposure.
