How to Collect a Sample for Lead (Pb) Analysis
Hygiene and Clean-Up when Collecting Your Paint Sample
Good hygiene practices are imperative when working with potentially lead-containing materials. Always wet-wipe any dust or debris generated during or after the sampling process. Soapy water is recommended for cleaning up any potentially contaminated dust or debris. Refrain from cleanup methods that could make potentially hazardous dust airborne, such as vacuuming. Once sampling is complete, carefully clean your tools as well as the immediate area, and wash your hands thoroughly.
Below you’ll find additional information about how to sample paint for lead (Pb) analysis. Please do not hesitate to contact us if you have sampling questions! If you’re looking to schedule an on-site survey, or want to ensure you are complying with local regulations, contact our field department!
How to Collect A Paint Sample for Lead (Pb) Paint Analysis
Step 1:
Two square inches (roughly the size of a credit card) is the minimum amount of paint required to test for lead (Pb). When collecting paint fragments or dust, please collect ~½ cup of the paint material. It is best to take at least 3 samples of bulk items to ensure you are accurately representing the material.
Make sure to chip or cut the paint down to the substrate to capture all existing layers. Be mindful to capture as little wood/substrate/inseparable materials as possible, as it could impact your analysis results. Each distinct paint type or color within the project area should be sampled separately. Don’t hesitate to contact us if you have questions about your paint sample.
Step 2:
Once the sample is collected, place it in an airtight container- such as a ziplock bag. Next, you’ll want to fill out our General Chain of Custody Form (COC), and choose your turnaround time (TAT) before submitting your sample to the laboratory.
Samples can be hand-delivered to our Milwaukie laboratory or, you may choose to use a delivery service such as USPS, FedEx, or UPS. When placing the baggies in a mailer, make sure that they are shut tight. Please mail the sample(s) to 3315 SE Harrison St., Milwaukie, OR 97222.

How to Collect Miscellaneous Samples for Lead (Pb) Analysis
For miscellaneous bulk items such as soil, please collect ~½ cup of the sample material. It is best to take at least 3 samples of bulk items to ensure you are accurately representing the material. Sample materials should always be placed into individual airtight containers, such as a ziplock bag. Dusty or loose material should be double bagged, especially when traveling via mail. Bulk items for lead (Pb) analysis should always be submitted with JSE’s General Chain of Custody Form (COC).
