Asbestos in Buildings: 10 Common Locations & Health Risks

Asbestos—banned in many countries post-1970s—persists in pre-1980 structures. Top 10 locations:

1. Pipe & boiler insulation (lagging)
2. Acoustic ceiling tiles
3. Vinyl floor tiles & mastics
4. Textured wall/ceiling coatings (popcorn)
5. Drywall joint compound
6. Cement roofing/siding shingles
7. Transite pipes & panels
8. HVAC duct insulation
9. Automotive brake linings (pre-1990s)
10. Electrical wire insulation (cloth-covered)

Health Risks

• Asbestosis (fibrosis)
• Lung cancer
• Mesothelioma (pleural/peritoneal)
• Pleural plaques, effusions

Do not disturb suspect materials. Engage licensed asbestos inspectors/abatement contractors. Encapsulation or enclosure may be safer than removal.
