Which approach involves maintenance and ongoing monitoring to control lead hazards?

The approach that entails maintenance and ongoing monitoring to control lead hazards is known as interim controls. This strategy focuses on reducing exposure to lead hazards without completely eliminating the source of lead. It typically involves implementing measures such as regular cleaning, maintenance of paint, and safe management of lead-contaminated dust or soil.

Interim controls are crucial in situations where immediate abatement is not feasible. They provide a practical solution by establishing temporary methods to minimize lead exposure while ensuring that continued vigilance and monitoring are in place. This ongoing oversight is essential to ensure that the controls remain effective over time, protecting residents or occupants from potential lead exposure.

Permanent abatement refers to more extensive measures aimed at completely removing lead hazards, while temporary containment focuses on short-term methods to manage lead until a more permanent solution can be implemented. Acceptable remodeling does not specifically target lead hazard control but rather involves alterations or improvements that may or may not consider lead safety. Therefore, the emphasis on maintenance and ongoing monitoring clearly aligns with the definition of interim controls.
