Which method is NOT recommended for cleaning up lead dust?

Using dry cloths
HEPA vacuuming
Wet cleaning methods
Using disposable sheeting

The correct answer is: Using dry cloths

Using dry cloths is not recommended for cleaning up lead dust because this method can easily stir up and disperse the lead particles into the air rather than capturing them. Lead dust requires careful handling to minimize exposure, and dry cloths may not effectively remove the dust, potentially leading to further contamination and inhalation risks. In contrast, HEPA vacuuming is specifically designed to capture and contain lead particles effectively. HEPA filters can trap very fine particles, including lead dust, which helps reduce the overall lead contamination in the environment. Wet cleaning methods are also favored as they can help prevent the dust from becoming airborne while simultaneously capturing and containing the lead; water or cleaning solutions bind the dust and make it easier to remove. Similarly, using disposable sheeting is effective because it can provide a protective layer that can be discarded after use, reducing the risk of lead exposure.
