What type of building construction is known as non-combustible?

The classification of non-combustible construction specifically refers to Type II construction, which is characterized by the use of materials that resist fire and do not contribute to structural collapse during a fire. In Type II construction, the structural elements, including walls, floors, and roofs, are typically made of steel and concrete, which are inherently non-combustible.

This type of construction is often used in commercial buildings, schools, and warehouses, where fire safety is a significant consideration. The non-combustible nature of Type II construction helps to improve fire resistance, enabling the structure to withstand higher temperatures for a longer duration without the risk of rapid structural failure.

Understanding the characteristics of various building types is essential for firefighting operations, as it helps first responders assess the potential hazards and challenges when combating fires in different construction styles. Other types mentioned in the question have varying degrees of combustible materials, which influences their fire behavior and hazards during an incident.
