Which method is considered unsafe for lead removal according to HUD?

Abrasive blasting without HEPA vacuum exhaust is considered an unsafe method for lead removal according to HUD guidelines. This method involves using high-pressure techniques to remove lead-containing materials, which can create airborne lead dust and debris. Without a HEPA vacuum to effectively contain and filter out the lead particles generated during the blasting process, there is a significant risk of lead exposure to workers and residents in the surrounding area.

The use of HEPA vacuums is critical in lead abatement because they capture fine particles that may otherwise escape into the environment, thereby minimizing lead dust contamination. Additionally, HUD emphasizes the importance of safety protocols and practices that protect both workers and occupants from lead exposure during removal processes. Proper methods must either contain lead dust during removal or ensure that no harmful lead particles are released into the environment.

Other methods listed, such as HEPA vacuuming, manual scraping, and professional abatement services, align with better safety practices and protocols established by HUD.
