Which paint removal technique is prohibited by HUD and EPA?

1. Using water spray

2. Dry scraping

3. Open flame burning or torching

4. Hand sanding

The correct answer is: Open flame burning or torching

Open flame burning or torching is prohibited by HUD and EPA due to the significant health and safety risks it poses during lead paint removal. This method can not only release toxic lead dust and fumes into the environment but also poses a fire hazard. The use of open flames can potentially ignite surrounding materials, leading to uncontrolled fires, and can cause serious respiratory issues for workers and nearby residents because of the toxic substances released. In contrast, the other techniques mentioned, while they may have guidelines and best practices to follow, are not outright banned. For example, using water spray can minimize dust but must be done in a way that prevents water damage. Dry scraping and hand sanding are also permissible under certain conditions, provided that they are conducted safely and with appropriate protective measures in place. The prohibition of open flame methods is thus a necessary regulation to enhance public safety and protect against lead exposure.
