This 1947 photograph was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH). The image depicted a number of employees in an Indiana lead battery manufacturing plant. Note that the workers were not using respiratory protection, however, it appeared that workstation ventilators were present.Workers can be exposed to lead through inhalation of fumes and dusts, as well as through ingestion as a result of lead-contaminated hands, food, drinks, cosmetics, tobacco products, and clothing. Furthermore, workers can take lead home on their clothes, skin, hair, tools, and in their vehicles, potentially exposing their families to this element's harmful health effects.
