What is one method of lead paint removal that contributes to contamination?

Sanding lead-based paint (LBP) is a method of removal that can significantly contribute to contamination for several reasons. When sanding occurs, tiny particles and dust containing lead are released into the air. This dust can settle on surfaces, contaminate the surrounding environment, and pose serious health risks, particularly to children and pregnant women.

Moreover, if proper containment methods are not in place during the sanding process, the lead dust can spread throughout the building and even into the community, exacerbating the contamination risk. This makes sanding an effective method for removing lead paint but one that also requires meticulous precautions to avoid the unintended consequence of lead exposure.

Other methods such as applying sealant or painting over with non-toxic paint do not lead to such contamination, as they encapsulate the lead paint rather than generate hazardous dust. Using chemical strippers, while it can be effective, may also have varying degrees of risk depending on the chemicals used and their application, but it typically isn’t associated with the same widespread contamination issues as sanding leads to.
