According to EPA & HUD, what is the size of the chip sample?

• A. 2 in x 2 in or 4 square inches
• B. 1 in x 1 in
• C. 3 in x 3 in
• D. 5 in x 5 in

Answer: (A)

The test is asking for the standard chip sample size specified by EPA and HUD for lead-based paint testing. The recommended chip size is two inches by two inches, which equals four square inches. This size provides enough material for reliable laboratory analysis to determine lead content while keeping the damage to the surface reasonably small. It also helps ensure the sample captures information from any layered paint if present. Smaller samples, such as one inch by one inch, may not yield sufficient material for accurate lab results. Larger samples, like three by three inches or five by five inches, would cause more unnecessary damage without added benefit and aren’t the required minimum. So the correct size, per EPA and HUD guidance, is two inches by two inches (four square inches).
