Which practice is prohibited in lead removal?

Manual dry scraping an area greater than 2 square feet is prohibited in lead removal practices because it poses a significant risk of lead dust and debris being released into the air. This method can create hazardous conditions for both the worker and the surrounding environment, as lead is a toxic substance that can cause serious health problems if inhaled or ingested.

In contrast, contained sandblasting, machine sanding with HEPA exhaust, and HEPA vacuuming are practices designed to minimize lead exposure. Contained sandblasting is done within a controlled environment to contain dust and debris. Machine sanding with HEPA exhaust helps filter out lead particles from the air, making it safer to use. HEPA vacuuming is an effective method for cleaning up lead debris in a manner that reduces the risk of spreading contamination. These practices adhere to safety guidelines intended to protect workers and occupants from lead exposure during removal activities.
