CDPH Lead Inspector/Assessor California State Practice Exam

If an employee has a Blood Lead Level (BLL) of less than 40 μg/dL, how often should they be monitored?

1. Every month for the first year

2. At least every 2 months for the first 6 months and every 6 months thereafter

3. Every three months indefinitely

4. Every 6 months only

The correct answer is: At least every 2 months for the first 6 months and every 6 months thereafter

When an employee has a Blood Lead Level (BLL) of less than 40 μg/dL, the recommended monitoring frequency is at least every 2 months for the first 6 months and every 6 months thereafter. This protocol is based on the understanding that while the lead levels are below the intervention threshold, it is still crucial to monitor these levels closely to ensure they do not rise, particularly in an occupational setting where exposure may fluctuate. The initial two-month interval allows for timely responses to any potential increases in lead levels, ensuring the employee's health is safeguarded. After this initial period, the less frequent monitoring of every six months is appropriate for employees whose levels remain stable and below the significant exposure limit, reflecting a balance between safety and the practicality of ongoing testing. This approach ensures that any upward trends can be identified early, and appropriate interventions can be put into place if necessary.
