The following statement is true or false: The concentration of lead paint in deteriorating housing must be greater than 1 mg/cm2 by XRF to pose a threat to workers doing renovation or abatement practices.

The following statement is true or false: The concentration of lead paint in deteriorating housing must be greater than 1 mg/cm2 by XRF to pose a threat to workers doing renovation or abatement practices.

• A. True
• B. False
• C. Cannot be determined
• D. Not applicable

Answer: (B)

Disturbing lead-containing paint is what creates a real risk for workers, not simply whether a single XRF reading surpasses a fixed number. An XRF test shows how much lead is present on a surface, but the danger comes from the potential to generate lead dust or create chips that workers can inhale or ingest. In deteriorating housing, even surfaces with lower mg/cm2 readings can pose a hazard if they are likely to be disturbed during renovation or abatement. Conversely, a higher reading on a well-sealed, intact surface may present less immediate risk than a badly deteriorated surface with a lower reading. Regulatory practice focuses on conditions and activities that cause dust or fragment paint to become airborne, not on one strict threshold. Lead-based paint is typically defined by its lead content by weight, and protective measures are required when such paint is present on surfaces that will be disturbed, especially if the surface is deteriorated. So, the idea that danger only exists when the concentration is greater than 1 mg/cm2 is not accurate.
