What are the primary hazards associated with Type I construction?

The primary hazards associated with Type I construction primarily concern the contents of the structure and the interior finish. In this type of construction, which is characterized by its non-combustible materials—commonly used in high-rise buildings—the main risk arises not from the structural materials themselves, but rather from what is contained within the building.

Contents like furniture, textiles, and decorative elements can be highly flammable and contribute significantly to the fire load. The interior finishes, such as wall coverings, ceilings, and the types of furnishings, can also influence how quickly a fire spreads and the potential for smoke production.

In terms of building safety, understanding these hazards is crucial. While the exterior walls of Type I structures are designed to withstand fire exposure, the presence of combustible contents and finishes presents a significant challenge during a fire scenario. Effective fire protection strategies must take into account not just the fire resistance of the building's structure but also the behavior of the materials used inside the building.
