Clearance testing is performed by taking XRF readings in four rooms of the house where abatement or renovations took place.

• A. True
• B. False
• C. Only in living areas
• D. Not required

Answer: (B)

Clearance testing checks that post-abatement dust levels meet the required standards, not the presence of lead in paint right after work. It uses dust wipe samples collected from surfaces that were disturbed or likely to accumulate dust, with the samples analyzed by an EPA-recognized laboratory. XRF readings are used to screen for lead in paint on surfaces during planning or execution, but they are not the method used to determine clearance. The number and locations of surfaces tested are based on the scope of work and regulatory guidance, not a fixed rule of testing four rooms. So, using XRF readings in four rooms does not describe how clearance testing is performed.
