There are two primary methods used to determine whether paint contains lead: XRF (X-ray fluorescence) analysis and paint chip sampling with laboratory analysis. Both methods are accepted by the EPA and the Ohio Department of Health, but they work very differently and have distinct advantages and limitations.
XRF Testing
An XRF analyzer is a handheld device that uses X-ray technology to measure the lead content of paint in place, without disturbing the surface. The assessor holds the device against a painted surface for a few seconds, and it provides an immediate reading of the lead concentration in milligrams per square centimeter. XRF testing is non-destructive, fast, and can be performed on virtually any painted surface.
XRF is the preferred method for lead risk assessments and inspections because it allows the assessor to test many surfaces quickly without causing any damage to the property. A trained assessor can test an entire apartment in under an hour using XRF equipment. The technology is highly accurate and is the standard used by certified risk assessors throughout Ohio and nationwide.
Paint Chip Sampling
Paint chip sampling involves physically removing a small sample of paint from a surface and sending it to a certified laboratory for chemical analysis. The lab determines the lead content of the sample and reports the results, usually within five to seven business days. This method is destructive it requires cutting or scraping paint from the surface, leaving a small area that must be repaired.
Paint chip sampling is generally used when XRF results are inconclusive, when testing surfaces that are not accessible to the XRF device, or when a property owner wants laboratory-confirmed results for a specific surface. It is also sometimes used in real estate transactions where buyers want independent lab verification.
Which Method Is Used for Cleveland Lead Safe Certificates?
Licensed risk assessors in Cleveland typically use XRF testing as the primary detection method, supplemented by dust wipe sampling to measure lead dust levels. Paint chip sampling may be used in specific situations but is not the standard approach. When you schedule a lead risk assessment with Ohio Lead Pros, our assessors use professional-grade XRF analyzers to provide accurate, immediate results during the on-site visit.
