Dust Levels for Hazard Screen - Floor are measured as which value?

• A. 10 ug/ft2
• B. 1 ug/ft2
• C. 5 ug/ft2
• D. 50 ug/ft2

Answer: (A)

Dust levels for a hazard screen on floors come from a wipe sample and are reported as the amount of lead per square foot. The floor hazard screen value is 10 micrograms per square foot, which serves as the screening threshold to flag potential lead dust hazards and trigger further assessment or remediation. Values much lower than this (like 1 or 5 μg/ft²) would be well below the screening trigger, while a result higher than 10 μg/ft² indicates a higher concern that warrants additional action.
