Which method is commonly used to reduce lead hazards in homes?

Encapsulation is a widely recognized method for reducing lead hazards in homes. This process involves sealing or enclosing lead-containing materials, such as lead-based paint, to prevent the release of lead dust or chips into the air. By using materials like special paints, coatings, or coverings, encapsulation creates a barrier between the hazardous material and the environment, effectively reducing the risk of lead exposure to residents, especially children.

In contrast, other methods listed are not suitable for addressing lead hazards. Composting does not relate to lead hazard control and is more relevant to organic waste management. Fumigation is primarily used for pest control and does not address lead exposure. Building renovation, while it can sometimes help in updating a property, can inadvertently disturb lead paint or lead dust if not done carefully, potentially increasing lead hazards instead of reducing them. Thus, encapsulation stands out as the most effective and appropriate method for mitigating lead-related risks in residential settings.
