If PCBs are found in the caulk, avoid regular touching of the caulk, clean it up properly and safely, and make plans to remove the caulk. The potential exposure to building occupants will be lower if they avoid areas where caulk may be present.
EPA is planning on evaluating potential Practical short-term options -- such as isolating the caulk by taping, sealing, or repainting -- that could reduce potential exposure.
In addition, when PCB-containing caulk is removed and disposed of, it must be done with care to avoid contamination of surrounding materials, such as floors, wood, bricks, mortar or soil.
How can I reduce risk to children or occupants if my school or building has PCB-containing caulk?
