Testing for Lead Paint

5/24/2016 (Permalink)

Character and history are two things many people love to have in their home. However, lead is not. If your home was built before 1978; there is a possibility that the paint is lead based. Lead has been known to cause health problems, espeaically in children. Here are a few simple steps to make sure your remodels goes as smoothly as possible.

STEP 1
Two common types of DIY lead test kits can be found in most hardware and paint stores: rhodizonate-based kits and sulfide-based kits. The type you choose will depend on the color of paint you’re testing. Rhodizonate kits are known to give false positives on red and pink paints, while sulfide kits are known to give inaccurate results on dark paint.

Once you’ve chosen the type of test that promises the most accurate results, you’ll find that most kits of either kind facilitate several tests for less than $100, which is considerably cheaper than hiring someone to perform the test for you.

STEP 2
On each wall, windowsill, or baseboard where you’re testing for lead, choose spots where the paint seems to be at its thickest (particularly if you suspect there are additional layers of paint underneath). Here, use a utility blade, or small, sharp knife to make a quarter-inch incision, slicing through the surface paint and revealing all the previous layers beneath it.

STEP 3
Most lead test kits come with swabs that require precise handling in order to use each one correctly. Generally, the swabs must be pinched in two designated areas in order for the solid and liquid chemicals inside to mix together. Next, you’ll open the swab to reveal the soft tip and press down on the incision made in the paint for the length of time specified on the test’s packaging (usually a few seconds). Apply pressure in a circular motion to make sure the swab has ample contact with each layer of exposed paint.

STEP 4
Now, look for a sign. Many popular rhodizonate-based test swabs will turn red if lead is present, although red paint (even traces of it from a previous layer) can create a false positive. Sulfide-based kits will turn dark grey or black, which of course can create a false positive when dark paint is already present. Even if you choose the correct test kit for your visible paint, additional testing may be required depending on the colors you find underneath.

STEP 5
Should your swab comes back clean, you’re likely in the clear, but double-check your work to be safe. Most test kits come with a confirmation card, which you can use to make sure the chemicals on your swab are reacting properly. The card comes with traces of lead on it, which will cause the swab to change color when it comes in contact with the paper. Now, if your swab remains colorless, you’re out of the woods.

IF YOU TEST POSITIVE FOR LEAD…
The Environmental Protection Agency (EPA) offers a specific set of steps to take if the paint in your home tests positive for lead. Since scraping and sanding painted surfaces can release lead dust and create an airborne health hazard, it’s important to take these steps seriously and follow them to the letter before beginning any renovations:

• Using the EPA’s locator, find a certified inspector or risk assessor to conduct a thorough testing throughout your home.

• Review the written report provided to you upon the testing’s completion, and ask for your inspector or assessor’s recommendations on whether you should seek an abatement professional to remove all lead completely or come up with a strict maintenance plan to prevent exposure.

• If abatement is recommended, the EPA’s locator can also help you find a lead paint abatement specialist. Once you’ve hired a certified professional to remove lead from your home, they must notify the EPA at least five days before beginning the abatement process. Depending on how much time you’ve spent in the home already, blood tests may be needed in order to determine your family’s level of exposure and whether any medical response is in order.

• If a long-term maintenance plan is recommended rather than abatement, you’ll be given a set of instructions that include regular inspections and, in the case of renovations, working only with lead-safe certified home contractors who know exactly how to perform their work in a way that’s safe for all involved.

Rest assured that the patience required to accurately ensure your home is lead-free is always worth it in the end. After all, “safety first” isn’t just a catchphrase; it’s a must for keeping you and your loved ones healthy and happy in a home of any age.
