What is the primary fuel load for Type I construction?

The primary fuel load for Type I construction is best represented by the contents within the structure. Type I construction is characterized by non-combustible materials, particularly in the structural components, which means that the building itself is less of a fire hazard. However, the contents within a Type I building—such as furniture, equipment, and other materials—are often combustible and can significantly influence fire behavior and severity during an incident.

In Type I buildings, even though the structural materials and the exterior finishes may play a role in fire dynamics, they do not contribute to the combustible load to the same extent as the contents. Therefore, understanding that the contents are the primary fuel load is crucial for fire officers when assessing fire risks, planning firefighting strategies, and conducting pre-incident planning. This knowledge allows fire officers to better prepare for potential firefighting efforts and manage fire dynamics effectively within Type I structures.
