Which of the following is a lead hazard evaluation method?

• A. XRF
• B. TCLP
• C. 29 CFR
• D. Risk assessment

Answer: (D)

Evaluating lead hazards in a home is about assessing actual risk to occupants, not just detecting lead presence. A risk assessment looks at how people could be exposed—through deteriorating paint, dust, soil, and typical daily activities—and combines that with factors like how long people are exposed, how children might ingest dust or soil, and which environments or behaviors raise risk. It then compares this information to health-based benchmarks to decide whether a hazard exists and what actions are needed, such as remediation or protective controls. Tools like XRF tell you how much lead is in a surface coating, which is useful data, but they don’t by themselves determine whether that lead poses a hazard or what level of intervention is required. TCLP is a test for lead leaching in waste, not for evaluating hazards in a living space, and 29 CFR is a regulatory standard, not a hazard-evaluation method.
