Which of the following options is NOT a method of interim control?

Interim controls are methods used to manage lead hazards and minimize exposure, typically involving strategies that are not permanent solutions but can provide quick relief or management of risk. Cleaning, monitoring, and temporary containment are all recognized as interim control methods because they directly address existing lead hazards and are often implemented in situations where immediate abatement is not feasible.

Cleaning involves the removal of lead dust and debris, ensuring that surfaces are safe and reducing the risk of ingestion or inhalation. Monitoring is crucial for assessing the ongoing presence of lead hazards and may involve regular inspections and testing to ensure that control measures are effective. Temporary containment, such as using barriers or sealing paint, is utilized to limit access to lead-contaminated areas and reduce exposure until more permanent solutions can be implemented.

In contrast, the construction of new buildings does not fit within the definition of an interim control method, as it represents a more permanent solution rather than a temporary measure. Building new structures may not address existing lead hazards in existing properties and can be a lengthy process, rather than a strategy that can be implemented immediately to manage lead exposure risks. Therefore, this option correctly identifies a method that does not belong to the interim control category.
