What should be done if lead dust is found during clearance sampling?

When lead dust is discovered during clearance sampling, the appropriate course of action is to perform additional cleaning and testing until safe levels are achieved. This is essential because ensuring that lead dust levels are below the regulatory thresholds is crucial for the health and safety of occupants, as well as compliance with lead hazard regulations.

After lead abatement activities, the clearance sampling aims to verify that the areas have been adequately remediated and that lead dust levels are acceptable. If lead dust is found, it indicates that the previous cleaning efforts were insufficient, and further actions are necessary to mitigate the risk of lead exposure. Continuing the cleaning process and retesting ensures that the environment is safe for reoccupation and that all regulatory requirements are met.

It is vital to maintain a systematic approach to lead abatement, focusing on achieving safe levels to protect public health. This option emphasizes the importance of thoroughness in lead hazard management and regulatory compliance.
