Questions and Answers about Polychlorinated Biphenyls (PCBs) in Building Materials
The specific questions and answers (Q&As) provided in this document are meant to help school administrators, building owners, managers and occupants better understand the types of building materials that may contain PCBs, the potential for building occupant exposure to PCBs, and how exposure to PCBs can be assessed and reduced.
Information presented in this document is broadly applicable and serves as practical guidance meant to reduce potential exposure of building occupants to PCBs within a reasonable time frame and under exposure conditions expected in schools and other buildings.
The diagrams below complement the document above in terms of how exposure to PCBs can be assessed and reduced in buildings. They describe actions for reducing exposures to PCBs in indoor building environments.
