Which of the following is NOT a form of lead abatement?

  1. Removal

  2. Containment

  3. Encapsulation

  4. Enclosure

The correct answer is: Containment

The correct answer is that containment is not considered a form of lead abatement. Lead abatement refers to the measures aimed at reducing or eliminating lead hazards in a structure, particularly in environments that have lead-based paint or lead-contaminated dust. Removal is a clear form of lead abatement where lead-based materials are physically taken out from the environment, thereby eliminating the source of lead exposure completely. Encapsulation involves treating lead-based materials with a sealant that prevents lead particles from becoming airborne or leaching into the environment, which effectively protects occupants from potential exposure. Enclosure entails constructing barriers around lead-containing materials to prevent access and exposure, thus securing the area from lead hazards. Containment, however, typically refers to practices that limit the spread of lead dust or particles during abatement processes rather than directly reducing or eliminating the lead hazard itself. While it is a necessary precaution during lead abatement activities to prevent contamination of the surrounding areas, it does not directly remove or minimize lead hazards; therefore, it is not classified as a form of lead abatement.
