According to HUD, which method is NOT recommended for paint removal?
Heat gun
Dry scraping
Sandblasting
Methylene chloride
The correct answer is: Dry scraping
The choice indicating dry scraping as not recommended for paint removal aligns with HUD's guidelines on lead safety. Dry scraping can generate lead dust, which is hazardous as it can easily be inhaled or ingested, posing a significant health risk, particularly to young children. Dust created by scraping is difficult to contain or clean up effectively, increasing the potential for lead exposure in the environment. While other methods, such as heat guns and methylene chloride, can also pose risks when not used properly, they are sometimes utilized in controlled environments with appropriate safety measures in place. Sandblasting can also release lead particles into the air, but it is not typically used in residential settings due to the potential for extensive lead contamination. In summary, dry scraping is viewed as problematic mainly because of the significant risk it presents in creating lead dust, making it the least recommended method for paint removal in the context of lead safety.
