Which method is effective for lead dust control during renovation work?

The method of using wet techniques to minimize dust creation is effective for lead dust control during renovation work because it significantly reduces the likelihood of lead dust becoming airborne. When performing renovations in environments that have been painted with lead-based paints, moisture can help keep the dust contained and less likely to spread throughout the area. Wet methods involve using water or other solutions when scraping, sanding, or demolishing lead-painted surfaces. This practice not only prevents the release of lead dust into the air but also aids in the cleanup process by ensuring that any debris generated can be more easily managed.

By contrast, employing dry sweeping methods would stir up dust and increase exposure to lead particles, while simply covering furniture with plastic does little to address the primary source of lead dust generation. Ignoring dust creation altogether is clearly unsafe and would not comply with safety regulations, potentially posing serious health risks to workers and occupants. Therefore, the use of wet methods is the recommended and most effective strategy for controlling lead dust during renovation activities.
