Environmental Protection Agency (EPA) Model Lead Based Paint Risk Assessor Practice Test

Where should dust samples be collected in a dwelling?

1. In kitchens only

2. In garages only

3. From all living areas accessible to children

4. Exclusively in bedrooms

The correct answer is: From all living areas accessible to children

Dust samples should be collected from all living areas accessible to children because children are particularly vulnerable to the harmful effects of lead exposure, which can occur through ingestion or inhalation of lead-contaminated dust. To accurately assess the risk of lead exposure, it's essential to sample areas where children spend time, as these locations are more likely to have higher concentrations of lead dust due to activities such as playing on the floor or touching surfaces. Collecting samples only from kitchens, garages, or bedrooms would not provide a complete picture of potential lead hazards in the home, as lead dust may be present in other common areas where children play or spend time. Thus, a comprehensive approach that includes all living areas is necessary to ensure an effective risk assessment and to protect children's health from lead exposure.
