Which abatement measure involves replacing building components?

• A. Enclosure
• B. Encapsulation
• C. Building component replacement
• D. Permanent soil covering

Answer: (C)

Replacing building components directly removes the lead source by taking out the old, lead-containing part and installing a new one. This approach eliminates the hazard at its origin, which is why it’s chosen when a component is deteriorated, structurally compromised, or not feasible to restore safely. Enclosure and encapsulation are containment strategies; they keep the lead-containing material in place behind barriers or coatings rather than removing it. Permanent soil covering addresses lead hazards in the soil around the building, not within building components. So, the method that specifically involves replacing the component is the replacement of building components.
