Beyond Asbestos and Lead: Understanding PCBs in Older Buildings
PCBs in Older Buildings
What Property Owners Should Know Before Renovating
When discussing hazardous materials in older buildings, asbestos and lead often receive the most attention. However, another environmental concern deserves consideration: polychlorinated biphenyls, commonly known as PCBs.
Once widely used in construction materials and electrical equipment, PCBs can still be found in aging commercial, industrial, and institutional properties. Understanding where these materials may be present is an important part of planning safe renovations, demolition, and building maintenance.
What Are PCBs?
PCBs are man-made chemicals historically valued for their durability, heat resistance, and insulating properties. They were commonly used in building materials and electrical equipment throughout much of the twentieth century.
Although their manufacture was banned in the United States in 1979, PCB-containing materials may remain in buildings constructed or renovated before that time.
Because PCBs break down slowly and can pose health and environmental risks, identifying and properly managing these materials is essential.
Where Are PCBs Found in Older Buildings?
Unlike asbestos or lead, PCBs aren't always associated with one particular building component.
Common sources of PCBs include:
- Caulking and sealants around windows, doors, and masonry
- Older fluorescent light ballasts
- Certain paints and surface coatings
- Electrical transformers and capacitors
- Some adhesives and construction materials
Buildings constructed or renovated between approximately 1950 and 1979 may be more likely to contain PCB-related materials.
Why Are PCBs a Concern?
PCBs can present potential health risks through prolonged exposure, including effects on the immune, reproductive, and nervous systems. Certain PCBs are also associated with increased cancer risk.
During renovations or demolition, disturbing contaminated materials may release PCB-containing dust or contribute to environmental contamination.
Additionally, improper disposal can create regulatory concerns and additional cleanup expenses for property owners and contractors.
The Importance of Testing Before Renovation
PCB-containing materials cannot always be identified through visual inspection alone. Professional sampling and laboratory analysis may be necessary to determine whether contamination is present.
Conducting environmental assessments before construction begins allows property owners to identify potential concerns, develop appropriate remediation plans, and avoid unexpected project interruptions.
When PCBs are confirmed, specialized removal, containment, and disposal procedures may be required to meet applicable environmental regulations.
