Why are dust samples taken?

Why are dust samples taken?

• A. To identify lead paint hazards; to see if the contractor cleaned up properly after renovation; to identify a dust hazard from lead that may not be paint
• B. To measure ambient temperature in the work area
• C. To determine the age of a building
• D. To check for lead content in drinking water

Answer: (A)

Dust sampling is used to detect lead dust hazards and to verify cleanup after work. It helps show whether renovation activities created lead dust that could expose occupants and whether the contractor has removed lead-contaminated dust from surfaces like floors and windowsills. It can also reveal lead dust hazards that aren’t tied to obvious paint, such as dust from other lead-containing materials or soil tracked indoors. By comparing wipe samples to regulatory standards, you can decide if further cleaning or remediation is needed. Dust sampling isn’t about ambient temperature, building age, or lead in drinking water—those require different tests.
