The choice of covering lead paint with non-lead paint is considered temporary containment of lead-based paint because it creates a barrier between the lead-containing substrate and the environment. This method effectively reduces the risk of lead exposure by sealing the lead paint underneath a non-toxic layer, minimizing the potential for lead dust and chips to become airborne or accessible, which can be a significant hazard, especially in homes inhabited by children or pregnant women.

This approach is not a permanent solution, as it does not eliminate the lead paint itself; rather, it merely encapsulates it. To maintain safety, periodic inspections and potential reapplications of the non-lead paint might be necessary to ensure the integrity of the containment continues to protect against lead exposure.

In contrast, complete removal of the paint is a more permanent solution rather than temporary containment. Specialized cleaning techniques may reduce lead dust but do not provide a physical barrier, so they do not qualify as containment. Installation of lead barriers typically involves more extensive measures and regulations, indicating a more permanent remediation approach rather than a temporary containment solution.
