Until the late 1970s, asbestos was the popular choice because of its acknowledged resistance to high temperatures and accessibility. The U.S. military in general and the Navy especially were known to have used asbestos-embedded materials in the shipbuilding and repairing processes. The mineral in question was especially dangerous for the personnel working in narrow spaces, like the rooms located below the deck because of the poor ventilation in those areas.
