What is the lead dust clearance limit for furniture?

• A. 40 ug/ft2
• B. 15 ug/ft2
• C. 60 ug/ft2
• D. 10 ug/ft2

Answer: (A)

Clearance limits tell you how clean a surface must be after cleaning to reduce lead exposure. For furniture, the standard is 40 micrograms of lead per square foot. This mirrors the commonly used floor limit because furniture is a horizontal surface that can trap and contact dust, posing similar exposure risks to people, especially children. If wipe samples from furniture exceed 40 μg/ft2, the area needs additional cleaning and a retest until the result is at or below this limit. The other numbers are for different surfaces (such as window sills or other areas) and aren’t the standard used for furniture.
