What is the OSHA lead blood level of concern for workers?

• A. 25 ug/dL
• B. 40 ug/dL
• C. 3.5 ug/dL
• D. 15 ug/dL

Answer: (B)

Lead exposure is tracked through blood lead levels because they reflect recent exposure and help gauge health risk. OSHA uses 40 micrograms per deciliter as the level of concern for workers, meaning this threshold triggers heightened action: medical surveillance should be initiated or intensified, the worker’s physician should be notified, exposure controls should be reviewed and improved to reduce lead exposure, and removal from exposure may be considered if levels remain high or rise. This level signals that health risks are present and proactive steps are needed, rather than waiting for higher numbers. The other listed values do not represent OSHA’s level of concern.
