Which is not a lead safe method to limit worker lead exposure?

The use of dry sanding methods is not a lead-safe approach to limit worker lead exposure. This technique generates a significant amount of dust and airborne lead particles, which can be inhaled or settle on surfaces, posing a serious health risk. In contrast, using HEPA vac attachments, minimizing sawing, and employing wet methods are all practices that can help reduce lead dust and exposure.

HEPA vacuums are designed to capture small particles, including lead dust, effectively preventing their spread. Minimizing activities that create dust, such as sawing, helps to limit exposure as well. Wet methods involve adding moisture to surfaces, which reduces the amount of dust generated during tasks like sanding or demolishing. Therefore, while the other methods are designed to safely control lead exposure, dry sanding allows for the potential dispersion of harmful lead particles into the environment.
