Describe "encapsulation" in lead hazard control.

Encapsulation in lead hazard control refers to the process of covering lead-based paint with a protective barrier. This method effectively seals the lead paint from potential exposure and minimizes the risk of lead dust or chips being released into the environment. The encapsulating material can be a special paint or a more durable barrier that adheres well to the surface with lead paint.

This approach is often employed when the lead-based paint is in good condition since it allows homeowners or property managers to manage lead hazards without incurring the cost and disruption associated with complete removal. It's especially useful in situations where immediate removal is not feasible, and it provides an effective means of controlling lead risks while maintaining the integrity of the structure.
