What term refers to dry, crumbling asbestos that is considered a health hazard?

The term that refers to dry, crumbling asbestos that poses a health hazard is "friable." Friable asbestos is made up of materials that can easily be crushed or broken into powder by hand, releasing asbestos fibers into the air. This airborne exposure can lead to serious health issues, including lung diseases and cancer when inhaled.

Asbestos itself is a group of naturally occurring minerals known for their heat resistance and insulating properties, but when it becomes friable, it loses its structural integrity, making it much more dangerous. It is crucial for professionals in real estate and safety management to be aware of friable asbestos locations, as handling and remediation of such materials require specific safety protocols to protect health and well-being.

The other terms mention different aspects: "asbestosis" is a lung disease caused by asbestos exposure, "porous" refers to having tiny holes that allow air or liquid to pass through, and "transparent" describes something that can be seen through but does not apply to the context of asbestos. Understanding these distinctions is critical for those working with or around potential asbestos materials.
