Environmental Protection Agency (EPA) Lead Risk Assessor Practice Exam

In what area of the home is lead most likely to be found as a hazard?

1. Gardens

2. Bathrooms

3. Living rooms

4. Painted surfaces

The correct answer is: Painted surfaces

Lead is most likely to be found as a hazard in painted surfaces. Historically, lead was commonly used in household paints, particularly in homes built before 1978 when the U.S. banned the use of lead in residential paint. This makes painted surfaces a significant source of lead exposure, especially when the paint deteriorates, chips, or is disturbed during renovations, which can release lead dust into the environment. While gardens, bathrooms, and living rooms could potentially have lead present due to various sources, such as lead-contaminated soil or older plumbing fixtures, the prevalence and direct risk associated with lead-based paint make painted surfaces the primary concern in residential settings. Lead hazards in the home context are primarily linked to the deterioration of lead-based paints on walls, windowsills, and doors, which can directly affect children’s health through ingestion of lead dust or paint chips.
