What is a common example of an exterior interim control?

A common example of an exterior interim control in lead abatement practices is paint stabilization. This method addresses issues related to lead-based paint that may be deteriorating or chipping on exterior surfaces. Paint stabilization involves properly maintaining and repairing surfaces that contain lead paint to minimize lead dust and potential exposure, making it a relevant approach in managing lead hazards.

Smoothing surfaces is also a part of overall lead hazard control strategies, but it relates more to the quality of surfaces rather than being a standalone interim control. Replacing windows can effectively eliminate lead hazards when windows are painted with lead-based paint, but it is more definitive and often considered a permanent solution, rather than an interim control which tends to be less invasive and more about managing existing conditions.

Prickly bushes do not relate to lead abatement practices at all as they do not mitigate lead exposure. Instead, they may serve as obstacles or barriers, which doesn’t address the critical need to manage lead-painted surfaces. Thus, paint stabilization stands out as the correct and relevant choice among the given options for exterior interim controls concerning lead hazard management.
