CDPH Lead Inspector/Assessor California State Practice Exam

Which of the following is a temporary control method for lead hazards?

1. New construction

2. Dust removal and control

3. Demolition of property

4. Installation of lead barriers

The correct answer is: Dust removal and control

The answer is focused on dust removal and control as a temporary control method for lead hazards because it directly addresses the immediate risk posed by lead dust, which can be a significant source of exposure in environments where lead-based paint or lead dust is present. Proper cleaning techniques and dust control measures, such as wet wiping and using HEPA-filtered vacuum cleaners, can effectively reduce the concentration of lead particles in the air and surfaces, thereby minimizing the risk to inhabitants, especially children and pregnant women. In contrast, new construction does not provide a temporary solution to lead hazards—it may even introduce additional risks if lead is present in existing materials. Demolition of property is a more permanent action and can generate substantial lead dust and debris if not done carefully. While installation of lead barriers can provide a temporary measure, they are not as immediately effective in reducing exposure as properly implemented dust removal and control practices. Therefore, dust removal and control is recognized as a key method for temporary mitigation of lead hazards.
