CDPH Lead Inspector/Assessor California State Practice Exam

What helps prevent lead exposure in older homes?

1. Regular painting and maintenance

2. Decreasing the number of rooms

3. Installing carpet

4. Using lead-free paint only

The correct answer is: Regular painting and maintenance

Regular painting and maintenance play a critical role in preventing lead exposure in older homes. Many homes built before 1978 may have lead-based paint, which deteriorates over time, creating lead dust and chips that can be harmful, especially to children. By regularly maintaining and repainting surfaces, homeowners can eliminate peeling paint, seal lead-painted surfaces, and reduce the risk of lead dust entering the living space. This practice also allows for the inspection of surfaces to assess any potential lead hazards, ensuring that any deteriorating lead paint is managed safely before it poses a risk. The other options do not effectively address lead exposure. Decreasing the number of rooms does not directly reduce the risk of lead exposure, nor does it promote safe living environments. Installing carpet may help in some instances by covering lead-paint dust on the floors, but it does not address the source of lead exposure and can create challenges in cleaning and maintenance. Using lead-free paint is beneficial for new work but does not directly remedy existing hazards associated with lead in older paint. Therefore, regular painting and maintenance remain the most comprehensive approach for preventing lead exposure in these homes.
