Which of the following is an example of abatement?

An example of abatement is the replacement of lead-based materials. Abatement refers to the process of reducing or eliminating lead hazards in a property. This is typically done through methods that are comprehensive and effective in removing the source of lead exposure, which often includes the removal and safe disposal of lead-containing materials, such as paint, pipes, or other fixtures.

While other options, like paint touch-ups, surface cleaning, or sealant application, can be part of lead management strategies, they do not constitute full abatement. These methods may reduce lead dust or seal in existing lead hazards, but they do not completely eliminate the lead source. In contrast, replacing lead-based materials directly addresses the hazard by removing it from the environment, thereby ensuring a safer living or working space.
