Which of the following best minimizes dust contamination in lead-based paint scenarios?

  1. Regularly vacuum floors

  2. Ensure thorough replacement of components

  3. Spray floors with water

  4. Limit access to evaluated areas

The correct answer is: Ensure thorough replacement of components

The best approach to minimize dust contamination in scenarios involving lead-based paint is through thorough replacement of components. This option effectively addresses the underlying issue by removing the lead-based paint and any associated hazards from the environment. When components such as windows, doors, or other painted surfaces are completely replaced, the potential for dust creation is significantly reduced since there are no longer lead-containing materials to deteriorate and generate dust. While regular vacuuming, spraying floors with water, and limiting access can help mitigate existing dust, they do not eliminate the source of contamination. Vacuuming can temporarily remove dust but may not fully capture lead particulates if the vacuum does not have a HEPA filter. Spraying water can suppress dust but doesn't remove the lead source, and limiting access does not address the contamination itself. Thus, replacing contaminated components is the most effective long-term solution for dust contamination in lead-based paint scenarios.
