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 stationed at a 'casting' machine, equipped with a local exhaust system in order to remove some of the toxic fumes emanating from the manufacturing process. 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. Only gloves were being implemented by these workers.
