At one time caulk was manufactured to contain PCBs because they imparted flexibility. PCB-containing caulk was used as a joint sealant in various architectural applications, including around windows, and masonry expansion joints.

It is known that caulk containing polychlorinated biphenyls (PCBs) was used in some buildings, including schools, in the 1950s through the 1970s. Buildings built after 1980 are less likely to contain caulk that contains PCBs.

Caulk is a flexible material used to seal gaps to make windows, masonry and joints in buildings and other structures watertight or airtight. To date it has been found in buildings in the northeastern United States and in joints in concrete water storage basins in the western United States.

* If you believe the caulk in your school or building was manufactured before 1978, when PCBs were banned, you may wish to have the caulk tested by a chemical analysis laboratory.


* 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.


* When PCB-containing caulk is removed and disposed of, it should be done with care to avoid contamination of surrounding materials such as floors, wood, bricks, mortar or soil.
