Which of the following professions may involve exposure to lead?

The profession of construction workers is particularly associated with exposure to lead due to the nature of the work they perform. Construction activities can involve the renovation, demolition, or repair of older buildings that may have lead-based paint or fixtures, as well as the handling of products that contain lead, such as plumbing materials or certain types of roofing materials. These workers may be directly exposed to lead dust or chips generated during these tasks, placing them at risk for lead exposure.

In contrast, while teachers and hospital staff may encounter lead related to specific environments, such as older school buildings or facilities with lead pipes, the likelihood of direct and consistent exposure is significantly less than in construction. Office workers typically work in environments where lead exposure is not a concern.
