Which practice can help reduce lead exposure on a worksite?

Using wet methods is an effective practice to help reduce lead exposure on a worksite. Wet methods involve using water or other liquids to suppress dust and particles that may contain lead during abatement processes. By keeping lead dust damp, it significantly minimizes the likelihood of particles becoming airborne and being inhaled or settled elsewhere. This approach is particularly useful in environments where lead-based materials are being disturbed, as it directly addresses one of the primary ways lead exposure occurs—through inhalation of dust or ingestion of lead particles that settle on surfaces.

In contrast, dry methods, while sometimes quicker, tend to create more airborne dust, increasing exposure risk. Unfiltered air can exacerbate the problem by allowing lead particles to circulate in the work environment. Additionally, using an ordinary vacuum may not effectively capture lead dust unless it is specifically designed for hazardous materials, as typical vacuums can release particles back into the air if they do not have proper filtration. Therefore, employing wet methods is recognized as a best practice in lead abatement to ensure a safer work environment.
