Which term is a natural fibrous mineral mined from the ground and resistant to heat and fire?

• A. Ambulatory care facility
• B. Airborne
• C. Barrier
• D. Asbestos

Answer: (D)

Asbestos is a natural, fibrous mineral that is mined from the ground and highly resistant to heat and fire. It consists of silicate minerals that form durable, needle-like fibers, which historically made it valuable for insulation and fireproofing in construction and industry. Because the fibers can become airborne and cause serious long-term health problems when inhaled, handling materials containing asbestos requires strict controls and specialized removal procedures. The other terms refer to facilities or infection-control concepts rather than a mineral with heat resistance, so they don’t fit the description.
