Michigan Residential Builders License Practice Test

Which work practice is recommended to minimize lead exposure during renovations?

1. Encapsulating lead paint when possible

2. Dry sanding all surfaces

3. Using high-pressure water cleaning

4. Ignoring small amounts of peeling paint

The correct answer is: Encapsulating lead paint when possible

Minimizing lead exposure during renovations is critical for protecting the health of workers and residents, particularly in homes built before 1978 when lead-based paint was commonly used. Encapsulating lead paint is a recommended method because it involves applying a special coating over surfaces that contain lead paint, effectively sealing it and preventing lead dust or chips from being released into the air. This approach not only protects occupants from exposure but also preserves the integrity of the painted surface. Choosing to encapsulate rather than remove lead paint outright can be more practical, less disruptive, and often less costly, making it a recommended strategy in many renovation scenarios. It is essential to ensure that the encapsulation is maintained over time, as any deterioration might again expose individuals to lead hazards. Other practices, such as dry sanding, can create lead dust and should be avoided. High-pressure water cleaning might not remove lead paint safely and can cause paint chips to spread. Ignoring small amounts of peeling paint is irresponsible, as even minimal exposure to lead can be harmful, especially to children and pregnant women. Therefore, encapsulating lead paint is the safest and most effective approach for minimizing exposure during renovations.
