Sealing, replacing, and repainting
Cleaning, encapsulating, and removal
Repairing, replacing, and sealing

The correct answer is: Removal, encapsulation, and enclosure

The three forms of lead abatement are removal, encapsulation, and enclosure. Removal involves physically taking out lead-containing materials, such as lead paint or lead pipes, from a building or environment. This is often considered the most effective way to eliminate lead hazards, as it completely eliminates the source of lead exposure. Encapsulation refers to the treatment of lead-painted surfaces with a special coating that acts as a barrier, preventing the lead dust and chips from becoming airborne or accessible. This method is useful when removal is not feasible or practical, allowing the lead hazard to be managed effectively while maintaining the integrity of the structure. Enclosure involves constructing a solid barrier around lead-based materials to prevent exposure to lead dust and chips. This can be done with drywall or other materials, creating a physical barrier that isolates the lead hazard from the living space. These three methods are recognized in national regulations and guidelines as effective strategies for managing lead hazards in homes and buildings. Other choices may involve related actions, but they do not specifically classify as the core forms of lead abatement recognized by authorities like the EPA.
