What activities can cause asbestos to become airborne?

Asbestos is a naturally occurring mineral that can become airborne through various activities, particularly those that disturb or damage materials containing asbestos. When asbestos fibers are released into the air, they can pose serious health risks when inhaled.

The correct choice identifies that any activities involving older buildings can potentially release asbestos fibers. This is because many older structures may contain asbestos in their insulation, flooring, roofing, or other materials. Renovation, maintenance, and even natural deterioration can disturb these materials, leading to airborne asbestos.

Activities such as demolition, renovations, repairs, or maintenance work can all disturb asbestos-containing materials, thereby releasing fibers. Furthermore, even minor activities, like drilling or sanding, can lead to fiber release in older buildings. It's important to recognize that the risk is not limited to major renovations or demolitions; routine activities that disturb materials can also be hazardous.

The other options incorrectly limit the scope of activities that can lead to asbestos release. For instance, suggesting that only demolition of buildings or only indoor renovations can cause airborne asbestos does not account for maintenance or repairs that may take place in both residential and commercial settings. Additionally, attributing airborne asbestos only to weather changes overlooks the various human activities that significantly contribute to the disturbance of asbestos fibers.
