Which of the following is a lead hazard evaluation method?

• A. TCLP
• B. RCRA
• C. Visual assessment
• D. XRF measures energy in electrons

Answer: (C)

Lead hazard evaluation starts with identifying conditions that could expose people to lead in a building. A visual assessment does this on-site by looking for deteriorated paint, peeling or damaged surfaces, chewable or accessible lead-containing materials, and other conditions that could generate lead dust or soil. This on-the-spot inspection helps determine if hazards are present and whether further testing is needed to quantify lead exposure. The other items are not used for hazard evaluation: TCLP is a regulatory leaching test for wastes, RCRA is a hazardous-waste law, and XRF is a instrument that can detect lead content but isn’t, by itself, a hazard-evaluation method described in this context.
