What material is primarily associated with asbestos exposure risks?

Insulation is primarily associated with asbestos exposure risks because asbestos fibers were extensively used in various insulation materials, particularly in buildings constructed before the 1980s. Asbestos was valued for its fire resistance, heat insulation properties, and durability, which made it a popular choice for insulating pipes, boilers, and even walls. When these materials are disturbed, they can release fine asbestos fibers into the air, posing significant health risks when inhaled, including respiratory diseases and cancers.

The other materials listed do not pose the same level of risk for asbestos exposure. Concrete and wood do not inherently contain asbestos, and while fiberglass is used for insulation, it does not have the same asbestos-related concerns. The association of insulation with asbestos highlights the critical need for protective measures and proper handling when working in environments where such materials may still exist.
