Asbestos may be found in facilities constructed before which year?

• A. 1990
• B. 1980
• C. 2000
• D. 1970

Answer: (B)

Old construction practices allowed asbestos use, so the presence of asbestos is most likely in buildings built before 1980. Asbestos was widely used for insulation and fireproofing in materials like pipe wrap, boiler insulation, floor tiles, and sprayed-on insulation up through the late 1970s. By the early 1980s, regulations reduced or halted new use, so buildings constructed after 1980 are far less likely to contain asbestos in new materials. However, older facilities may still have ACMs from renovations or remaining materials, so you should treat pre-1980 structures as potentially containing asbestos.
