What blood lead level thresholds indicate medical removal when considering average or single test results?

• A. 20 ug/dL average
• B. 30 ug/dL average
• C. 50 ug/dL average or 60 ug/dL on a single test
• D. 70 ug/dL average

Answer: (C)

Medical removal is triggered when blood lead levels indicate a health risk, using either the average of tests or a single elevated result. If the average of two or more consecutive tests reaches 50 ug/dL or higher, the worker should be medically removed from exposure. If a single test shows 60 ug/dL or higher, that alone also triggers removal. Lower numbers or other thresholds don’t meet the standard for removal. This approach accounts for natural fluctuations in testing while ensuring protection from lead-related health effects.
