CDPH Lead Inspector/Assessor California State Practice Exam

What action is required if an employee has a BLL between 40 μg/dL and 50 μg/dL?

1. Normal monitoring every 6 months

2. At least every two months until two consecutive blood analyses are less than 40 μg/dL

3. Immediate medical removal

4. Weekly monitoring

The correct answer is: At least every two months until two consecutive blood analyses are less than 40 μg/dL

When an employee has a blood lead level (BLL) between 40 μg/dL and 50 μg/dL, the appropriate action is to conduct monitoring at least every two months until there are two consecutive blood analyses demonstrating a BLL of less than 40 μg/dL. This option aligns with the protocols set forth by health guidelines to ensure that individuals at risk are closely monitored and to evaluate the effectiveness of any interventions implemented. The frequency of monitoring is crucial in this range because it reflects a significant level of exposure that needs to be addressed. Monitoring every two months allows for timely intervention and management of the employee's exposure to lead, safeguarding their health and preventing further increases in BLL. In contrast to this, choices that suggest longer intervals, such as normal monitoring every six months, would not provide the diligent oversight required at this critical BLL range. Similarly, options that imply immediate medical removal or weekly monitoring do not align with established medical guidelines, which focus on careful observation and gradual intervention rather than immediate removal or excessively frequent monitoring without justification.
