CDPH Lead Inspector/Assessor California State Practice Exam

What is a significant concern regarding targeted and worst case sampling protocols?

1. They are too cost-effective

2. Worst case sampling requires entry to all units

3. Targeted sampling can be too extensive

4. They require lengthy training

The correct answer is: Worst case sampling requires entry to all units

The concern around worst case sampling protocols stems from the requirement for entry to all units involved in the survey. This type of sampling is designed to identify the most hazardous conditions that could potentially lead to lead exposure. To accurately assess these worst-case scenarios, inspectors must access multiple units, which can pose logistical challenges, including scheduling conflicts and tenant privacy issues, as well as potential pushback from occupants. This necessity for comprehensive access is critical for an accurate assessment, making it a significant concern when implementing such protocols. While cost-efficiency and training length are important factors in sampling protocols, they do not directly relate to the immediate practical concerns that arise from needing to access all units for worst case evaluations. Similarly, the extent of targeted sampling, while it can raise its own issues, does not encapsulate the primary challenge that worst-case sampling presents in terms of unit accessibility.
