EPA Lead Risk Assessor case studies

EPA Lead Risk Assessor · Put your knowledge to work in context.

The EPA Lead Risk Assessor credential is a federal certification under TSCA Title IV Section 402 that authorizes an individual to conduct on-site risk assessments in target housing and child-occupied facilities. Where a lead-based paint inspector determines whether lead-based paint is present and where, a risk assessor goes further: interviewing occupants, evaluating paint, dust, soil, and water data, identifying deterioration and friction/impact surfaces, and judging which conditions actually create a lead hazard for the people living or working there. The EPA Lead Risk Assessor case studies are 5 cases and about 3,910 words.
