Which of the following is an example of an interior interim control?

The selection of painting as an example of an interior interim control is correct because interim controls are temporary measures used to manage lead hazards until permanent controls, such as lead abatement, can be applied. Painting is commonly used to seal lead-based paint surfaces and prevent lead dust or chips from becoming airborne, thereby reducing lead exposure risk in a home or building.

In the context of lead hazard management, painting over lead-based paint is considered a practical and effective interim control method. It helps to maintain the integrity of surfaces and minimizes the immediate risk posed by deteriorating lead paint. This approach is particularly useful when full abatement is not immediately feasible, allowing for safe living conditions.

Other options, such as mulch, prickly bushes, and planting sod, are typically considered more relevant as exterior controls. While they can contribute to reducing lead exposure in outdoor areas, they do not directly address interior lead hazards in the same manner that painting does. Therefore, painting is the most appropriate choice when discussing interior interim controls.
