What is asbestos primarily used for in construction?

Asbestos is primarily recognized for its serious health hazards associated with inhalation, leading to lung diseases like asbestosis, lung cancer, and mesothelioma. This reflects a critical aspect of its historical use in construction, where it was valued for various properties but ultimately deemed hazardous.

While asbestos was indeed used in fireproofing and insulation applications (which might relate to some of the other options), its primary identification and significance in discussions surrounding health and safety in OSHA training is the serious risk it poses to workers and occupants. The choice that highlights its potential to cause severe health issues accurately encapsulates the current understanding of asbestos and its implications in construction settings. Understanding these risks is crucial for ensuring safety in the workplace, underlining the importance of compliance with OSHA regulations.
