Practical Notes
Due to the highly hazardous nature of asbestos (carcinogenic), the manufacture and installation of these tiles are obsolete and largely banned.
This code serves primarily as a historical reference for engineers, architects, and demolition experts assessing existing old buildings.
When encountering tiles compliant with this code in existing structures, strict asbestos abatement and disposal protocols must be followed.
