Which method is used for paint removal as an abatement measure?

• A. Paint removal by heat gun, chemical, or contained abrasive
• B. Soil removal and replacement
• C. Enclosure
• D. Encapsulation

Answer: (A)

The main concept here is identifying methods that directly remove lead-based paint from surfaces. Removing paint uses techniques that physically strip or eliminate the painted coating, such as applying heat to soften the paint, using chemical strippers to dissolve it, or performing contained abrasive blasting to remove layers while keeping dust contained. These approaches target the source of the hazard—the lead paint itself. In contrast, enclosure and encapsulation are containment strategies. Enclosure covers or encloses the painted surface to prevent exposure without removing the paint, while encapsulation seals the coating to reduce dust release. Soil removal and replacement addresses lead contamination in soil, not paint on surfaces, so it isn’t a method for removing paint itself.
