Which of the following is considered a low risk deleading activity?

Removing and replacing window sashes on hinges is categorized as a low-risk deleading activity primarily due to the limited potential for lead dust generation and exposure during the process. This type of work typically involves replacing the sash rather than completely removing the window frame or structure, which can disturb lead-based paint less aggressively.

In contrast, activities such as removing interior walls or demolishing kitchen cabinets tend to disturb a larger area of lead-based paint and can generate significant dust, posing a higher risk for lead exposure. Stripping exterior paint is also considered high risk as it may produce lead-laden dust and debris, creating a hazardous environment if not managed properly. Therefore, the relative safety of replacing window sashes on hinges makes this choice appropriate under low-risk activities within deleading practices.
