Asbestos fibers can be released from which of the following conditions?

Asbestos fibers can be released from deteriorating materials, particularly in situations where asbestos is used in construction, such as in insulation for steam pipes and boilers. Over time, heat and moisture can damage asbestos-containing materials, causing them to become brittle and fray. When these materials deteriorate, microscopic fibers can be released into the air, posing health risks if inhaled.

Steam pipes and boilers often contain asbestos insulation to manage heat effectively. If these systems are improperly maintained or become damaged, the asbestos can become airborne, especially when repairs or renovations are carried out. Therefore, the presence of steam pipes and boilers is a significant risk factor for asbestos exposure in construction and maintenance activities.

While other conditions may affect the structural integrity or effectiveness of asbestos materials, they do not directly lead to the release of asbestos fibers to the same extent as steam pipes and boilers do.
