Where should encapsulants be avoided in lead hazard control?

Encapsulants are materials applied to lead-based paint surfaces to prevent the release of lead dust and chips; however, their effectiveness is significantly compromised on friction and impact surfaces. These surfaces, such as window sills, doors, and floors, are subject to constant wear and movement, which can cause the encapsulant to break down, leading to potential exposure to lead hazards.

In contrast, common areas, outdoor areas, and underneath appliances may still be feasible locations for encapsulant application since these surfaces typically do not experience the same degree of physical disturbance. Applying encapsulants in these settings can be a viable option for managing lead paint hazards. It is important for a lead risk assessor to recognize the limitations of encapsulation, particularly in areas that experience direct friction and impact, where the risk for lead exposure remains heightened.
