Environmental Protection Agency (EPA) Lead Risk Assessor Practice Exam

What are the two categories of lead hazards identified in a risk assessment?

1. Surface hazard and atmospheric hazard

2. Material hazard and surface hazard

3. Toxic hazard and physical hazard

4. Environmental hazard and health hazard

The correct answer is: Material hazard and surface hazard

The correct answer identifies the two categories of lead hazards as material hazard and surface hazard, which are essential in understanding and assessing lead risks in environments such as homes, schools, and child care centers. Material hazards refer to lead-containing materials, like lead-based paint and dust, which can pose risks if they are deteriorating or disturbed. This encompasses lead that is embedded in building components and furnishings, where deterioration can release lead particles into the environment. Surface hazards pertain to the presence of lead on exposed surfaces, such as peeling paint or lead dust accumulation. These hazards are particularly concerning in areas where children may interact with these surfaces, leading to potential ingestion or inhalation of lead particles. In risk assessments, these distinctions help professionals evaluate the specific sources and pathways through which lead exposure can occur, enabling more effective mitigation and remediation strategies. Understanding these categories is fundamental for correctly identifying and addressing lead hazards, ultimately protecting public health, especially vulnerable populations such as children.
