Which technique can be used to minimize lead dust during cleanup?

Wet cleaning methods are highly effective in minimizing lead dust during cleanup because they involve the use of water or cleaning solutions to dampen surfaces before cleaning. This reduces the amount of dust that can become airborne, helping to contain lead particles and prevent them from spreading throughout the environment. By using moisture, the likelihood of inhalation exposure to lead dust is significantly decreased, making wet cleaning a preferred option in lead hazard remediation.

In contrast, other techniques like dry sweeping can actually exacerbate the problem by stirring up existing lead dust into the air. Vacuums without HEPA filters might not capture all the fine lead particles, allowing them to escape back into the environment. Chemical solvents may also not effectively address lead dust, and their use can introduce additional hazards or require special handling procedures. Therefore, wet cleaning stands out as the most effective method for controlling lead dust during cleanup.
