Which exterior components can be grouped together for lead assessment?

The correct choice involves components that are directly related to the exterior of a home and are commonly assessed for potential lead exposure risks. Windows, porches, lower trim, and upper trim are all significant areas in the context of lead hazard assessments.

Windows above 5 feet are assessed because they are often associated with lead dust and chipping paint that can pose a risk, especially in older homes where lead-based paint may have been used. Porches also present similar concerns as they are frequently coated with paint that could contain lead. Both lower and upper trims are likewise critical areas; trim often has painted surfaces that can deteriorate and release lead particles into the surrounding environment.

The grouping of these components is logical due to their shared characteristics and relevance in lead assessments, which focus on painted surfaces and potential exposure points in residential settings. This also aligns with the established guidelines for identifying lead hazards as part of risk assessment practices.
