What is the proper procedure for cleaning up lead dust?

Using a damp cloth or a HEPA vacuum is the correct procedure for cleaning up lead dust because these methods are effective in minimizing the release of lead particles into the air. Lead dust can be hazardous when disturbed, and using a damp cloth helps to capture the dust particles rather than just moving them around. This method significantly reduces the risk of inhalation or further contamination.

HEPA vacuums are specifically designed to filter out very small particles, including lead dust, making them a safe and efficient option for cleanup in environments where lead exposure is a concern. These vacuums can effectively collect lead dust without redistributing it into the air, ensuring a safer environment for both workers and residents.

Using a broom and dustpan or an ordinary dry cloth is not advisable, as these methods can stir up dust into the air, increasing the risk of inhalation. Additionally, leaving the dust to settle before sweeping is not a safe practice since lead dust can still pose health risks even after settling, and relying on settling does not adequately eliminate the hazard. Thus, opting for a damp cloth or HEPA vacuum provides a more effective and safer approach to lead dust cleanup.
