Which of the following is an acceptable way to reduce lead exposure in a home?

To effectively reduce lead exposure in a home, the removal of lead-containing materials or their encapsulation is one of the most reliable methods. This approach directly addresses the source of the lead hazard, ensuring that there are no materials present that can release lead dust or chips, which pose a significant health risk, especially to children and pregnant women.

Removing lead-containing materials involves the safe disposal of items such as old lead-based paint, contaminated soil, or lead pipes. Encapsulation provides a protective barrier over lead-containing surfaces, preventing the lead from deteriorating and becoming airborne. Both strategies aim to eliminate or contain the lead source effectively, minimizing the risk of lead exposure.

Other methods, while potentially helpful, do not address the root cause as directly. Regularly using household cleaners or relying on proper ventilation and air purification can help reduce dust and airborne particles but may not eliminate all lead hazards. Solely depending on paint removal can be inadequate if it is not executed properly or if lead-laden dust remains. Thus, the removal or encapsulation of lead-containing materials is the most definitive and comprehensive action to take for lead exposure reduction in a home.
